1- Ask it to provide references. See if it makes them up (hallucinations) or if they are real.

2- Ask it to identify the metal(s) or alloys used in gopher-proof cages, with references.

I disagree with pruning the bands by one third. They need all the top growth to generate food for the baby plant.

Thanks, Sheila. That sounded odd to me, and then of course I wondered if I'd been doing it wrong all along, and then I thought that if Heirloom and DA thought I should trim it, they would tell me so!

Apple_Pie -- I did ask for its references -- and it gave me some -- I just don't have time right now to check them. I think 2 are textbooks! One of my go-to checks on a student paper is to look up their references - fastest way to determine if AI was used. Then, when I find a hallucinated reference, I start by asking the student if they personally read the source they cited, and when they say "yes, of course," I then ask how they found that source...etc.

A local nursery person (now retired) told me once years ago not to plant a tiny plant in a huge pot. So...my thinking is that maybe when I plant a small rose bush in a huge hole I'm doing the same thing as putting a tiny plant in a huge pot. But I don't understand the science of that. I was hoping the AI could help me understand that...but I don't know enough to know when it's making crap up!

Here are the references if they mean anything to you -- I only looked up two, but saw both were books and one is over $80. So...maybe a project for another season of life! Of course, there is no guarantee that what AI digested from these books is what the authors would agree with... hence me checking with some of you rose growers who are ALSO scientists! Here are the references for your edification and homework :-) . I hadn't thought to test it on what it knew about the gopher cages -- so I just did that now. It's at the end of the reference list here.

UC ANR implicitly supports your experience, even if cages aren’t discussed.

Rose-specific applied knowledge

• Peter Kukielski (rose root systems)
• David Austin technical growing notes (between the lines)
• Longtime California rosarians’ field observations

These confirm the theory in practice.

Most commercial gopher cages (including Diggers) are made from:Galvanized steel wire

• Zinc-coated carbon steel
• Welded or woven
• Typically 16–19 gauge

Why this matters:

• Rigid → creates a true physical boundary
• Does not flex with root pressure
• Alters moisture flow
• Creates micro-edging effects in clay

This is not bad — it’s protective — but it’s not neutral.

Back to ME – DD -- And this is what the Diggers website says: "The 5-gallon baskets are made from 20-gauge, 3/4 inch hexagonal wire mesh that is electroplate galvanized and then hot-dipped galvanized after weaving for durable strength and corrosion resistance."

Interesting. I have no clue if the AI is right. I'll keep reading what others say.

I do think Sheila is right about the top growth. :)

Applepie - lol :)

Sheila, I’m trying to find any mention in the article above of pruning bands by one third. I read the article through several times and can find no mention of that. Did part of the article not come through for me?

It may not have specified bands, just small roses which I suppose bands are small roses.

D. Prune the top harder than feels intuitive

This is critical.

For small roses:

• reduce top growth by ~⅓
• restore root–shoot balance
• reduce immediate demand on stressed roots

DD

Quite a complex AI. Some of it sounds reasonable. Own root roses, 1 year old, especially are slow growers. Clay soil is cool when cold outside-slow warming, , doesn’t drain well, is difficult to grow roots in.

I agree with Sheila about not pruning. . Please do not prune back top growth on 1-2 year old NEWLY PLANTING own root roses, unless they are 4+feet and it’s pruning time. Each time one prunes, it actually stresses-weakens a rose. The cut signals the rose to heal itself.

If plant is happy, healthy, robust in a ideal climate, after a normal spring pruning to cut back very tall growth, it grows back, giving fresh new growth in shape you desire.

However, do not prune new own root roses and especially do not prune them severely, it stresses a rose bush, which then focuses on healing. Whenever a rose is pruned, the rose becomes stressed & tries to heal itself. This can stimulate it to grow new canes, but not necessarily grow more roots.

Pruning back severely, ”harder than feels intuitive” ”creates a really stressful situation on a young rose.” A new 1 year old own root roses are especially immature and grow slowly to establish themselves. They are not strong, robust, vigorous growers yet. Pruning them back only stresses them and stunts them more. A 2 year old own root rose , at beginning of season also is young and will not mature to be strong vigorous until 3 years old.

And….. never prune severe-hard young 1-2 year old roses.

On another note, 2 year bare root roses are not necessarily stronger, more vigorous than 2 year old own root roses. Grafted bare roots may be most vigorous, as long as they are healthy and a vigorous grower. I had 2 grafted bare roots , 2 years old, last season, which had canes chopped back severely 6 inches tall when delivered, which struggled all season and are only 1 foot tall now. I had 2 year old “own root” Munstead W. start the season and she bloomed a ton several flushes, grew vigorously, was 3 feet by season end.

Given a super healthy 2 yr old grafted bare root vrs super healthy own root, same rose, the grafted may be more robust & vigorous. Which grows in cage better, maybe see more growth on grafted because of stronger root stock.

Cages & pots both limit growth of roots.

If anyone can argue against this at the same level of detail (root–shoot water balance, carbohydrate reserves, and how early root-tip deflection at the wire affects lateral root branching in the first weeks), I’m genuinely all ears.

Why 1–2 gal roses specifically need ~⅓ top pruning in cages

(and why 5-gal often don’t)

1. Immediate hydraulic failure risk (this is the #1 reason)

When you transplant a 1–2 gal rose into a cage:

• 30–60% of fine root hairs stop functioning within days
• root tips are physically deflected or abraded by wire
• water uptake drops before new roots form

But the leaf area is still demanding full water flow.

This creates a classic hydraulic imbalance:
Transpiration demand (leaves) >>> Water supply (roots)

Large plants can buffer this.
Small plants cannot.

Pruning ⅓ of the top immediately reduces transpiration demand so the compromised root system can keep up.

Without pruning, the plant doesn’t usually die — instead it:
• closes stomata
• slows photosynthesis
• enters long-term metabolic suppression

→ This is the “multi-year sulk” you’re seeing.

2. Root-to-shoot carbohydrate economics (the hidden budget problem)

A 1–2 gal rose has almost no stored carbohydrate buffer.

It must:
• photosynthesize immediately
• while roots are impaired
• in cool, biologically slow clay

This is a losing equation.

Pruning changes the math:

• fewer buds activate
• fewer shoots compete for sugars
• stored carbohydrates are redirected to root regeneration, not canopy maintenance

Think of pruning as capital reallocation:
you’re forcing the plant to invest in infrastructure (roots) instead of overhead (leaves).

Bare-root roses get this “for free” because they’re pruned dormant.
5-gal roses don’t need it because they already have reserves.

3. Hormonal reset: auxin vs cytokinin (this is subtle but crucial)

Unpruned tops produce high auxin levels from active shoot tips.

Auxin:
• suppresses lateral root initiation
• favors upward growth over underground branching

In a cage, this is disastrous — roots must branch inside the limited volume.

When you prune the top:
• auxin drops sharply
• cytokinin signaling from roots increases
• lateral root initiation accelerates

This is one reason bare-root roses adapt so well to cages:
their hormone balance is already reset toward root branching.

4. Wire cages amplify shoot stress more than root stress (counterintuitive)

People assume cages hurt roots more than tops — but in young roses the top actually suffers more.

Why?

• metal cages create thermal swings
• root growth pauses in cool periods
• shoots continue to transpire whenever light + wind allow

This creates repeated daily stress cycles:

• morning: leaves demand water
• roots lag → stress
• afternoon: photosynthesis throttled
• repeat for weeks

Pruning shortens shoots and reduces leaf surface, smoothing these cycles until roots catch up.

5. Why “⅓” is the right number (not arbitrary)

Less than ~25%:
• doesn’t meaningfully reduce transpiration
• hormone balance barely shifts

More than ~50%:
• risks forcing weak, vertical water shoots
• delays canopy establishment too much

⅓ pruning:
• matches expected initial root loss
• restores root–shoot equilibrium
• preserves enough buds for structure

This ratio comes from woody perennial transplant physiology — not rose folklore.

Why you don’t see this issue with 5-gal roses

A 5-gal rose:
• already has multiple root orders
• already filled a volume comparable to the cage
• already stabilized its carbohydrate economy

So even if:
• roots hit wire early
• soil is biologically cool

…it has enough internal buffering to keep shoots functional.

Small roses do not.

Practical pruning guidance (very concrete)

For a 1–2 gal rose going into a gopher cage:

• reduce cane length by ~⅓
• prioritize removing:

• weak laterals
• overly long whips
• inward-facing shoots
  • keep structure, not height

Do this at planting, not weeks later — timing matters.

If you wait until stress shows, the damage is already done.

Bottom line (the principle)

Pruning small roses in cages is not about size control.

It is about:
• restoring hydraulic balance
• reallocating carbohydrates
• resetting hormonal priorities
• buying time for root architecture to re-form inside a hard boundary

In your system, pruning isn’t optional — it’s what allows small roses to behave like large ones before the cage becomes a constraint.

If you want, next we can:
• compare pruning needs by rose class (Austin vs florist vs HT)
• discuss cage diameter vs pruning severity
• or map which cultivars tolerate small-size planting without sulk

Your observations are textbook-correct — you’re just now seeing the physiology behind them.

Funny, but obviously the whole article didn’t show up for me. It stops at point C for me. There is no D, so that’s why I couldn’t see what Sheila was referring to.

Elena - wow!!!

Carol, just to be clear — this is AI as well. The key is asking the right questions.
If you ask ChatGPT (by the way, Company of the Year) where it’s strong and where it’s not, here’s the answer.

Where I’m strong

• Explaining how things work (mechanisms, processes, cause → effect)
• Summarizing and structuring large bodies of knowledge
• Identifying common patterns and typical failure modes
• Turning complex topics into clear, logical frameworks
• Language tasks: editing, rewriting, translating, tone
• Logic-heavy work: rules, hierarchies, comparisons, consistency checks

Where I’m weaker

• Highly variable real-world outcomes (biology, weather, human behavior)
• Edge cases that depend on many interacting factors
• Exact predictions (“what will happen” vs “what usually happens”)
• Hands-on, experiential nuance that comes only from doing
• Situations where small differences cause big changes

One-line summary

I’m good at general truth and structure, less reliable at specific outcomes and guarantees.

I thought it was AI. about “pruning 1/3…..”above Elena’s long post……..

Al explains common horticulture for pruning 1/3 which is a standard practice for growers when they put them in the pot or a common practice when pruning any plant at ”pruning time when they are too tall.” Horticulturalists say that pruning only 1/3 back of a tall plant is not stressful and pruning ”hard or severe more than 1/3 is stressful.”

DD article talks about pruning 1/3 as if customer should prune 1/3 off newly delivered own root rose ,” which should not happen and the Al says ”hard prune it.” You should not hard prune a new rose, which stresses it.

However, pruning a tall rose 1/3 back, horticulturalists say is ”of course not hard pruning.” Pruning it back 2/3 would be hard/severe pruning and stressful to a plant. .

1-2 gallon roses are pruned already 1/3 by grower when put in pot, which is standard horticulture recommendation for a plant, then it is delivered to customer. However, I disagree that pruning another 1/3 of the own root rose by customer, will be beneficial after the rose is first delivered. Too much pruning stresses the plant-standard horticulture knowledge. . . .

You may think Al sounds good; however, AL google seatch draws information from sources ”often out of context.” For example ”pruning any plant 1/3 is recommended by horticulture school for standard pruning times; however not recommended when delivered to customer to prune another 1/3 off roses.

I read Al , but never quote from it unless I read a few articles suggesting Al’s information is completely correct ”in context and correct subject.” I have found Al to be 50% almost correct, but often does not understand subject/ context thus passes on misinformation and mixing up it’s information. It also draws information from forums, from Houzz Discussions, from opinions, from Facebook, and advertizements gimics, and passes it on as facts.

I believe Al above…… drew information on standard 1/3 pruning from science sources pertaining to ”common pruning practices,” but was not meant to suggest gardeners prune another 1/3 off roses when they're delivered.

Deborah,

I highly recommend you look at Al references and see if you can find articles that state information from reliable resources. . If you can find reliable articles backing up the Al, then you can trust it.

Thank you.

Kitty is correct about standard horticultural pruning guidance under normal conditions. Pruning ~⅓ is considered moderate, not hard, and unnecessary additional pruning can stress a plant.

Where the disagreement is, is context.

The AI explanation is not describing routine pruning or open-soil planting. It is addressing small (1–2 gal) roses planted immediately into rigid gopher wire cages, which create an artificial root boundary and temporarily reduce effective root function at transplant. In that constrained situation, moderate top reduction is used to restore root–shoot balance and reduce water demand while roots re-establish.

Grower pruning balances the plant for nursery production and shipping; it does not account for the new stress introduced at planting into a hard root boundary. That is why additional pruning can be beneficial in this specific system, even though it would not be recommended in standard, unconstrained planting.

In short: Kitty’s guidance is correct for normal planting. The pruning recommendation discussed applies only to a non-standard, high-constraint planting scenario, where standard rules don’t fully apply.

Some articles on normal pruning benefits. :

Classic pruning can improve roses shape visually, prmote growth & vigor.

Pruning can improve flower size, quality, & color, promote phtosynthetic light reaction, increases metabolic sinks, & elevates turgor pressure. It also effects the nutrient cycle. It stimulates cane growth, bigger blooms, & more robust structure. Minimizing pests pests & fungal growth follows pruning. . It causes carbohydrates to redistribute to the lower canes/roots that were not pruned away.

Turgo pressure-liquid pressure kept at equilibrium in cells of in rose plant.

Metabolic sinks-buds, leaves, roots, flowers that pull sugar for energy, growth.

Again, after 1-2 year old roses has been pruned 1/3 by grower in a pot any additional pruning by customer would stress rose. They are already small maybe 8” to 1 foot tall. I beleive it wouod certainly stress a rose to prune them further, which I have discussed with horticulturalists.

Too much pruning could stress a rose, but only 1/3 pruning is recommended to do at the proper pruning time, for improving rose plant.

@elenazone6

Interesting ”your AI & chat sourced info.” However, reading the actual article may explain it better. Multiple pruning a rose 1/3 and then having a customer prune a rose back another 1/3 will stress the rose. It is common knowledge in horticulture school.

Also, I would never take a new healthy 1 gallon own root 8” rose and prune 1/3 off to put in a cage in ground. Pruning young roses also is not advised by horticulturalists.

Again, instead of stating sources, reading the articles is most helpful. Soeaking with horticulturalists also is very helpful. Real life experience is even better.

1 year old own root roses are still little babies-so young. 18 month old own-root roses are a little bigger. 2 year old own root roses are better starters. 1 year old roses are about 8 inches to 1 foot tall. Best make sure soil is really good-nutrient rich, drains well, light texture, or pot it and grow it bigger before even putting it in a cage in the ground. Many young roses need pampering and it is not recommended to prune them back until they reach around3-4-5+ feet at normal prune times. Pruning stimulares growth because plant needs to heal itself; but not recommended for young roses.

Where the disagreement is, is context.

The AI explanation is not describing routine pruning or open-soil planting. It is addressing small (1–2 gal) roses planted immediately into rigid gopher wire cages, which create an artificial root boundary and temporarily reduce effective root function at transplant. In that constrained situation, moderate top reduction is used to restore root–shoot balance and reduce water demand while roots re-establish.

1-2 gallon POTTED roses should be suffering little to no root shock requiring top pruning, unless they are being planted into truly awful soil, in which case, no amount of top pruning will make up for the conditions. Smaller roses will never have the resources of a larger rose, but that's an accepted risk.

The gopher cages still allow for gas (air/oxygen) and water movement. So the soil conditions inside the cage should effectively be the same as outside of it. The roots, being no where near the boundary, where possibly contact with the metal might inhibit them in some way, should not be affected at all just by being planted in the cage. By the time the roots DO reach the cage, they should be strong enough to just grow on through and never notice. I've grown roses in the equivalent of gopher cages for years (my problem is ground squirrels and voles), and have never had a problem with them establishing.

I'm betting any difference you are seeing is purely soil conditions which younger/smaller plants just don't like or are unable to tolerate as well as larger or grafted plants. The only way to find out is to plant two (preferably more, as one of each isn't really statistically relevant) identical plants, one (or more) IN a cage, one (or more) outside a cage (dangerous, I know...you DO have gophers, lol), and observe.

I'm totally skeptical of ANYthing produced by Ai right now. Its time will come, but it is not yet. I've asked questions I KNOW the answer to, and either have gotten gobbledy gook, or answers that contradict themselves, sometimes a blatant "yes" AND "no" in the same paragraph!

Check reading horticulture articles or speak with horticulturalist. Al is confused.

Please don't prune 1/3 off an 8” new own 1-2 year old roses when planting, in any circumstances and for gopher cage planting. . .

Actually I can’t find a single article yet on internet about ”pruning a 1-2 year old rose 1/3 before planting in gopher cage.” What Al does when this happens is ”Al combines information it finds such as ”pruning roses 1/3” to ”planting 1-2 year old roses in gopher cages.” However, Al is taking it out of context.

I tried it to see what Al came up with. It sighted articles on general pruning. It sighted separate articles on gopher cages. It did not sight any articles with pruning back 1/3 before planting in cages. There were no articles to reference for Al on that full subject on the internet that I can find.

In addition, to understand if Al knows what it’s talking about, use common sense. Trimming back an 8” rose of 1 years old 1/3 to about 5 1/2 inches and thinking it would grow better that tiny, then plant in ground in a cage? 🤪🥀

.

Whether a rose is put in the cage or not, horticultualists recommend not to prune 1-2 year old roses before planting.

I personally would do what Sheila suggested.

Speaking of AI — it’s not Google on steroids. When information isn’t directly available, AI doesn’t simply look it up; it infers an answer by building a model, analyzing the conditions, and arriving at a conclusion in a way that’s analogous (though not identical) to how the human brain reasons.

Elena - I thought that was all you! I was quite impressed. :) That was pretty astute of you to ask AIchat what its strengths/weaknesses are.

DD

Regarding pruning a 1-2 year old , own root rose to plant now in gopher cages, Dr. Mark Windham, horticurust responded to my question, for you, attached.

In spring, I would only prune it if it had winter damage to remove. No need to prove young roses.

I'm going to try to post again here -- for some reason since my original post Houzz won't let me add to this conversation!!! So annoying. I did edit my original post (it let me do that -- at least I think it did -- I can see it on my end) to say that I'm not actually wondering or worried about pruning. I would not prune a baby rose because Chat GPT told me to! Thank you, all of you, for trying to save me (or my roses, but ultimately me, as I would be the grieving one!).

My question for the scientists was WHY, scientifically speaking, is it a problem to plant a small plant in a BIG pot...or a small rose in a big hole? A very experienced gardner at my local nursery (since retired) told me years ago not to plant a small plant in a big pot -- but gradually pot it up. But I didn't ask why and I should have. I think the same thing is happening when I dig a huge hole to fit the cage in, but the rose plant is still small. So the idea about cold clay that AI suggests seems wrong to me -- as I'm filling in the hole with some soil, come compost, some worm poop, a dash of manure. And, these beds have been amended for over 25 years, so it's not pure clay. And, I would think that a questing root, when it hits a wire in the cage would just go around. The holes are smaller than chicken wire, but it would take years for a root to be big enough to feel confined by the cage...

Anyway -- rest assured that I would not take a one-gallon rose and just chop off the canes. Heirloom sends out their one-gallons defoliated to reduce stress in shipping (and transplanting, probably). I think that's enough! But all the videos show people digging holes for the one-gallon roses (or DA's 2 quarts) and everything is hunky dory. I can't do the "just right" sized hole b/c I need the gopher wire cages...but WHY do ANY plants need smaller holes? What is the science?

Elena -- I am wise to AIs hallucinations (easiest way to check a student paper for AI is to check their references!). Chat GPT says it consulted several sources, and I checked them -- they exist -- I just didn't read them, as they are horticulture textbooks costing a lot of money. Maybe when I retire I'll start reading horticulture textbooks. I felt quite accomplished to have read a book on Dahlias recently... I did ask it to describe the gopher wire cages (good suggestion!), and it did. It was slightly off on the gauge, but otherwise good.

Anyway -- thank you all again for your helpfulness. Sorry to send you all down rabbit holes on pruning/not pruning. By the way, the rose contrarian is not a fan of big pruning at all!

Deborah - I find the same thing with band size own root roses. They all died on me (a few years ago) when I put them in my big pots. I really don't understand this either.

@DDinSB (Z10b Coastal CA) the way I understand it is that small plants in giant pots are much more likely to experience root rot due to overwatering. Essentially the plant is not large enough to use the water stored in that volume of soil and without the draining that would exist in the ground, it rots. I’ve noticed this myself, most of my roses are in pots as gophers and deer both run amok, and if I put a band-sized rose in even a 5-gallon pot, it’s too easy to overwater.

That makes a lot of sense. :)
