It’s a good idea to test the seed varieties you decide to include in your stash. Each one will have its own preferred climate, soil, and growing style. It often takes trial and error to find the best match for your garden. If the variety you choose is adapted to perfect soil, chemical fertilizers, long summers, and frequent doses of fill-in-the-blank-icides, then it probably won’t produce well using organic methods in so-so soil, with late spring frosts and early winters. Find a variety that fits the way you garden, and you’ll get MUCH better results.
Varieties with a lot of built-in diversity, such as landraces or grex varieties, will be highly adaptable.
I recommend books like “The Resilient Gardener” by Carol Deppe, and “Teaming With Microbes” by Jeff Lowenfels and Wayne Lewis. There’s an endless list of other books I’d recommend, but those will cover quite a lot.
I grew up on and lived on a farm with greenhouses most of my life.
My own experience is that with proper weed and insect control, you get good results. Those two are a learning experience.
This year I did about 20 different varieties of specialty peppers and 15 different varieties of tomatoes.
Made the mistake of not sorting the pepper plants by Scoville units when planting so I had to tie a red plastic ribbon on the super hots an orange ribbon on the medium, and yellow on the mild.
I planted a dozen Carolina Reaper and Ghost Peppers for the heck of it. Those are dangerous!
My wife accidentally picked one of the cute little Thai Hots and burnt her mouth pretty bad.
My tomatoes are almost all on wire trellis system like grapes. The increased air flow and sun really helped keep disease to a minimum.
I enjoy vertical gardening. Easier to care for the plants, weed, till, harvest, ..... highly recommend it.
