If/when you have acres you can rotate. I have grown tomatoes in the same beds for over 15 years without a problem. Compost and then add compost.

I've been planting tomatoes in the same beds for 15 years. Pretty much the same every year. Rotation is something large ag installations do when they can't amend the soil regularly. You can. Crop rotation is NOT a useful gardening strategy for home gardeners. Please ignore whoever is telling you to do it.

One of the main reasons for crop rotation is the carry-over of plant-specific pathogens and insects from year to year. By rotating crops to different soil every year you eliminate most of this. It is effective IF you have the room to do it. I'm like you... don't have the room. Also, many plants that would normally die-out in winter go on from year-to-year here in central CA - like peppers and tomatoes.

Agree with the others above. I do practice rotation, but understand it isn't feasible in most cases. Adding amendments, especially compost, is a big factor when not rotating.

Keep an eye on your plants, if you continuously grow veggies in the same family. If you discover a disease on your plants, don't assume it's from growing the same plants in the same spot. Make sure you identify the disease and determine if you are dealing with soil-borne or airborne pathogens. Most of the diseases encountered in the garden are airborne.

It is true that if you have a pest or disease problem, skipping that bed with that plant for a season is smart. Just about the only strategy to get rid of SVBs is to do that. Their pupae overwinter in the soil, and emerge the following season. Serious fungal infections may also be a good reason to move. Yes, diseases are usually airborne, but a lot of the air contains stuff picked up from the local soil. So if you rotate, do it for a reason. Not just so you can say you rotated.

I try to do a little bit of crop rotation in my small 1500sqft garden. I'm an inexperienced gardener, just my second year with anything other than a couple of tomato plants or something similar...so what do I know? :) The idea of running from a disease or pest is good, but in a smallish garden I can see that it's not really going to work much...but it might just a little. ;) The primary reason I'm trying to rotate things is so I can move my nitrogen-fixing peas to different parts of the garden and follow them with something that will benefit from that nitrogen. And, if a bug crawls out of the bug in the spring of the year and is confused that his favorite vegetable isn't growing close by for him to chomp on that's fine too...even if he'll eventually find it, at least he'll have to work for it.

Definitely adding compost is a good thing, I wish I could have a compost pile but down here the fire ants think of them as a luxury resort and move in uninvited. There's nothing like starting to turn a pile and suddenly white ant eggs and thousands of vengeful fire ants are heading towards you! But yes, being in a smaller garden we can amend and take more detailed care of our soil. As for the big farms rotating crops...that seems to be something that is going by the wayside with mono-cropping. I mean, how many years in a row can you grow corn in a field? Better living through chemistry.<sigh>

But, is crop rotation necessary for a small garden, nah, but will it help?...in my mind...it might. ;)

I'm baffled as to why crop rotation would not be possible in smaller gardens. My garden is permanent beds--in ground, not raised. It's good sized, but not huge. I simply rotate what is in one bed to the next bed, with a little variation for one hill planting of zucchini, and have been doing so for many, many years. I grow a very wide range of vegetables and grow deep into the winter when I am harvesting savoy cabbages, sometimes in January. By February, I'm sowing spinach and parsley directly into the beds.

I have beds with variable sun. One bed is vastly better for tomatoes than others. My tomato beds have fixed trellises. It would require a lot of work to move those. Not simple. No one says it isn't possible to rotate. We're just saying that it isn't really necessary.

<We're just saying that it isn't really necessary.>

And in many (small) home gardens will accomplish nothing as the separation distance is negligible.

One reason to do crop rotation is if you have root knot nematodes on a specific crop. I noticed root damage when I pulled my old tomato plants last winter, so I put the tomatoes and other nightshades in a different bed this year. I have 3 small raised beds so I can rotate. If I hadn't noticed the nematode damage, I wouldn't have bothered.

If you have a SPECIFIC REASON to rotate, as in, avoidance of something in the bed, sure, then do it. There are a number of such specific reasons. Heavy infestation of fungal spores in a tomato bed, SVBs in a squash bed, etc. etc. But it is not important as a general practice for a home gardener that is practicing regular bed amendments.

"And in many (small) home gardens will accomplish nothing as the separation distance is negligible."

Agree. It all depends on how one defines "crop rotation". Simply moving things from one row to another or from one bed to an adjacent bed in the same yard with the same soil isn't really crop rotation in the real sense of the term.

True crop rotation involves a very wide diversity of crops used, large field-wide distance separations, field dormancy periods, interim cover crop plantings, often heavy or even delayed tilling, etc. All well beyond the average home gardener.

So if you can move things around - fine. Just don't expect it to make a big difference. But if you can't for many reasons then you focus instead on soil improvement and the control or elimination of the problems in the specific area.

In my Pot Farm I can easily dump the soil from the pot into the green bin and just start over, something that's hard to do with raised or in-ground beds.
