One thing I don't want you to take from this video (or any of or videos) is that you need to change your systems/rotations if they're working for you. In other words, if it ain't broke don't fix it.

It should be remembered that historically rotations were used in combination with a return to fallowed perennial pasture to maintain productivity of fields. This was in a time that we didn’t have fossil fuels and other cheap energy to truck tons compost and mulch materials around. We also didn’t have the many other fertility sources from products of industry and extraction (also available because of fossil energy). Primarily rotations would be applied to large plots growing staple crops; in small home gardens one would still be able to apply more of these techniques of mulching and large compost applications.
I tried rotating them 🤷♂️ the stems just snap.
Only complaint about this channel is your so good at these videos you only need to make one video a week. And I’m such a nerd I can’t get enough
Glad I am not crazy...wait...
It’s quite a quandary! On the home scale it’s even worse. My suggestion is keep your soil healthy, watch your plants, diversify whenever you can and basically hope that works. In the home garden (or allotment) it is very very difficult to NOT cross-contaminate between different parts of the garden. On the other hand, to truly do crop rotation is a true pain in the a%$e 🙄. Great video Jesse, like them it it really makes you think!
I typically plant a winter cover crop (crimson clover) over my tomato bed and call it a day. That being said I have little space. Last year we got some septoria leaf spot, so I will probably move them. Thanks for calling out trellis material as I would have just tossed it in without thinking!
I enjoy these types of videos. Having grown up on a farm we had the standard 4 crop rotation...corn...soybeans...winter wheat...alfalfa. So it doesn't surprise me most of the literature revolves around some variant of this cycle. But what I feel is important...these are the yearly produced crops. So there is a winter between each harvest. And we tilled. Not what gardeners deal with. Basically I am saying I am not sure I would put too much emphasis on the scientific results involving biodiversity health. I will say...it makes sense diseases and pests can only be controlled by rotation ...so for that reason yea...do it. But to say fungal diversity is better? I am not yet convinced that is the case. Just too many variables...many confounding...playing a role
there are some people that think crop rotation is bogus because nature doesn't grow a different thing in that spot every year, but if we don't mess with it, the vegetation in a spot will change over multiple years or even decades. And like you said every farm is different, every farm is in a different stage of life depending on where they started from and how long they've been growing and what kind of management they practice. I think we always need to look at the research and see what resonates with us, that we might be excited to experiment with in our own environments. In all farm things one size never fits all
home garden you can poly culture with mixed planted beds , however that would be impractical for a business grower
I really appreciate the stopping point, there are always more garden videos than time
I like the no dogma approach, Jesse. It makes crazy good sense to say that for a backyard gardener rotating to minimize pest or disease is probably not going to be effective. A big take away from this for me is that the idea of crop rotation is probably more benefiacail to large growers of staple crops.
This is amazing. I'm an official super nerd (personally and professionally lol); we expand our urban garden every year. I've been frustrated with finding clear information on crop rotation- literally every article gives a different pattern! I've always wanted to distill down the science but you did it for me! Great job!
Yay! I did celery in the high tunnels where the tomatoes were last year. What I did, since you asked, is I transplanted the celery up the center of the beds between the tomato rows. BTW, celery doesn't take as long to germinate in late summer as it does in the late winder/early spring and in Japan celery is primarily considered a winter crop.
Jesse, for the cucumber powdery mildew problem .. look up Lofthouse Landrace Gardening videos. He talks about huge PM problems in his operation for years until he crossed enough cucumbers and kept survivors until PM became a non-issue for him. I got a little of his group's cucumber seed last year and had no PM problems where I couldn't get barely anything through PM prior. The commercial seed growers are using lots of inputs to ward off disease and essentially adapting their survivors to relying on heavy chemical inputs.
Love the respect you convey to your viewers. You are not out to proselytise.
A historical perspective on crop rotation: J.I. Rodale and Mokichi Okada were contemporaries a century ago. Rodale is credited with popularizing organic gardening/farming in the US and Okada started Natural Farming (Shinzi Shumeika) in Japan. A big difference is Rodale promoted crop rotation and Okada promoted growing the same crop in the same place every year. In the 90s, Rodale hosted interns and study groups from Natural Farming, in part to learn about crop rotation because they were experiencing plant health issues posssibly due to planting the same crop in the same place every year.
Thanks for doing all that research, sure got me thinking about separating tomatoes and cucumbers completely
