Sweet potato seedbed arrangement matters: master the method for good seedling results
The adventitious buds on sweet potatoes are most numerous at the head end, fewer in the middle, and fewest at the tail end. When arranging seed potatoes flat or at a slant in the seedbed, follow the principle of head end up, tail end down, back side up, belly side down to increase the number of sprouts. If large and small tubers are arranged in the same seedbed, large tubers sprout slowly and produce few but sturdy seedlings, so they can be placed...
The adventitious buds on sweet potatoes are most numerous at the head end, fewer in the middle, and fewest at the tail end. When arranging seed potatoes flat or at a slant in the seedbed, follow the principle of head end up, tail end down, back side up, belly side down to increase the number of sprouts. If large and small tubers are arranged in the same seedbed, large tubers sprout slowly and produce few but sturdy seedlings, so they should be placed in the middle; small tubers sprout quickly and produce many seedlings, so they should be placed on both sides. Large tubers should be arranged densely and deeply, while small tubers should be arranged sparsely and shallowly. After arranging, the tubers can be drenched with diluted human and livestock manure water, then covered with fine fertile soil, with a soil thickness sufficient to hide the tubers from view. After covering the seed potatoes, build an arched frame and cover it with film to keep warm for seedling cultivation.
