Western; I buy plants, but they are small. Some in 2 inch pots, and others in 4 inch pots. I grow heirloom varieties, with the exception of a couple of Celebrity plants, that are behind the others currently. The Celebrity are "insurance" in case the heirlooms don't produce due to some weird Texas weather. They are not my favorite flavor, but will work on a burger, and to freeze for recipe use in the winter. I could never give $7/plant, as I put out WAY too many to give that (usually 45-75 plants!).
I grow organically, so use lots of compost from here on the garden. If I feel the soil needs a bit more, I'll buy the occasional bag of Back to Nature, cotton burr compost, and top dress around the plants. it does cost about $7/bag, but I never need more than a bag or two a year, with the "home grown" compost that I have.
If you end up short on okra seed, let me know, I will probably have an ounce of seed leftover, even if I have to replant okra, yet again. I grow an old heirloom variety of that, and it produces better than anything I have ever tried, and tastes great too! I could drop it off somewhere, for you to pick up, or mail it to you. I have friends that like the same variety, and I order it, so always get plenty, so we can all plant it. Most years, I have some left over, but with replanting this year, and others replanting, might be able to get all of that seed in the ground! You are welcome to it, if you need/want it!
