We’re making good progress with catching up on our big transplanting tasks. We’ve planted the Roma paste tomatoes, peppers, melons, okra, eggplant, yet more lettuce and over half of the sweet potatoes. After this there’s “just” the watermelons and leeks to go. Then only the roughly weekly lettuce planting until the fall brassica transplanting shifts in late July and August. In order to give our transplants the best chance of thriving, we never plant in the mornings (except leeks), and prefer to make the extra effort to plant late in the day. That way, the plants have the cool of the night to get established before being called on to photosynthesize, transpire, extract water and nutrients from the soil, deter bugs and all the many plant tasks we don’t even know about. Currently we are transplanting 4-6 pm each day, with just a small group of people so that everyone focuses on planting and we are not training new people (a feature of our big morning work shifts).
This year we are once again planting our sweet potatoes on ridges with drip tape and biodegradable plastic mulch (bioplastic). Here’s a photo from last year:
Sweet potato vines grow to completely cover the area and the plastic is out of sight and being digested by the soil micro-organisms. Very little hand-weeding is needed. I think last year we did one walk-through (wade-through!) weeding.
The deer have reappeared and as sweet potato leaves are one of deer’s favorite foods, we got ourselves prepared, installing two Scare Crows, one at each end of the patch. These are water sprinklers activated by motion detectors. We’ve found Scare Crows quite effective against deer. They seem to have dropped off the market. Havahart is selling the Spray Away which looks similar but I haven’t tried. They can only be used during the frost free period, because you have to leave the water supply hooked up. As sweet potatoes will only be in the garden during the frost free period, this is a good match!
This spring we are trying a new lettuce variety: Sword Leaf (Yu Mai Tsai) Looseleaf Lettuce.
This is a fast growing, productive Asian lettuce. It has a sweet flavor and plenty of crunch. In our climate, I think it would not do well in summer. Better for spring and fall. We bought seed from Southern Exposure Seed Exchange You can read about it here, on this TaiwanFinn Blog. “Taiwan (and Luxembourg) Through the Eyes of a Finn”. one comment says this is known in the English-speaking world as Celtuce. But Kitazawa Seeds sells both. With celtuce, the stem is the main part eaten. With Sword Leaf it is the leaves. So I’m doubting they are the same.
