We put in four 4x4 squares, in late March. Hubby put small pvc-type pipes cross-ways over the tops and when it was to get cold or frosty, we draped clear plastic over the beds. Every thing came up and was growing life crazy. THEN...suddenly the red onions started going south. Then the tomatoes started wilting. Then we started watering ALOT more and the tomatoes perked back up. The bush beans didn't produce like I expected. The "lady fingure" squash hasn't produced as I expected. The bell peppers haven't produced as I expected. The heirloom corn was the pits, and the hybrid corn caught up with it! The carrots did great, the radishes did great, the yellow neck squash went crazy and I've had to use my special "veggie soap" to keep the squash bugs off it and the other winter squash that's coming on. Not sure if we've worked any less...??? Next year we're making some changes to where we position the produce. We tried to keep low growers on one side of the beds and tall growers (like corn etc.) at the backs. We love not having to weed etc. Next spring, we're planning to put in 4 more 4x4's but maybe deeper and putting corn etc. in them so they can draw from more Mel's Mix. Anyway...for the most part, we figure it's a combination of our inexperience with sfg, draught, and thinking heirlooms would produce more than hybrids. I don't want to dry & preserve my own seeds. I'd rather just vacume seal tons of them and store them in my freezer. Anyway, just couldn't resist posting about our square foot gardening experience. Oh, still not sure how our buckets of potatoes are going to turn out. Chalking lots up to experience!
