Valrose: is that your typical result at 31 days?

Even if it's not: very impressive.

Typical when everything is perfect. I'll get calluses in a week and roots in 2 weeks. I've been rooting roses for 25 years and it's still a little hit and miss.

Some people mix equal amounts of perlite and vermiculite in a 3 to 4 inch pot and place them in a tray in order to keep the pots moist and root them that way like this article from hedgerow rose blog (not mine). She roots in cowpots. I am going to try them.

I've had little trouble with them actually rooting, but how do you get the roots to grow so well and thickly?

That's the dip n grow. I use it 1 to 10 parts water ratio

A lot of it is variety/type dependent. Some roses want to root, and grow well own-root. Some just plain don't.

Valrose, do you mean that you water the cutting with this 1-10 solution the whole time it's developing roots? Lisa

Never water with Dip n Grow. Just dip the about 1" of the bottom inch of the cutting in the solution for about 5 seconds. Then "stick" the cutting in the rooting soil. No need to premake holes like you do with rooting powder. I like to take a handful of cuttings and dip them all at once. Saves time. I use new growth, just hardened off enough to be stiff. My cuttings are also very short, seldom more than 3 leaf nodes. Also I use intermittent mist and am rooting under a cover to give me about 50% shade.

For what it is worth, the arithmetic is as follows: Pour product to the concentration line, i.e. the lowest line in the little beaker. Then add water to your desired "factor" or "multiplier" line. So for example, for a 10x solution, you put product to the bottom line, then add water to the 10x line. When you make a 10x solution, you are actually making up a 1:9 ratio, i.e. one part product and 9 parts water. The instruction leaflet says to dip for 3-5 seconds, no longer. A longer time is counter-productive. "John" at Dip n Grow told me on the phone that rose growers generally use solution strength in the range of 10x to 15x. Try an eyedropper to make up the correct ratio in a smaller quantity for just one or two cuttings. Avoid any kind of rooting medium containing fertilizer; for example, many peat-based "potting soils" contain fertilizer and are not recommended for this purpose.

I rooted roses for many years before I even heard of rooting hormone. Many roses root easily, so they don't need fancy equipment, or special stuff.

For me, all posts on Houzz are in one thread today. Is this happening for everyone?

Clear your cache (history, or whatever) in the browser. It was happening for everyone for a while, but has been fixed.

I use a 1 cap full of Dip n Grow to 10 cap fulls water. Here is Rossette Delizy at 17 days.

Sorry for the poor photo quality. Hopefully you can see the thick white roots. That is due to the rooting hormone. The rooting powder from Home Depot works as well, it's just more trouble. The holes for the cutting have to be pre made to keep the soil from rubbing off the powder.

Here is the whole tray.

If the soil doesn't come with added fertlizer, then I add a coated slow release at 2 weeks. I've tried cuttings in a controlled trial, fertilizer and no fertlizer. No difference in rooting success, but early fertilized group grew tops much faster and had a better survival rate when potted up.

Never found a rose variety that wouldn't root. Found plenty of varieties that had low vigor as own roots.
