There are several reasons why Sweet potatoes did not produce:
- The season was too short, sweet potatoes are a long season crop and most of the tuber formation occurs at the end of the season. They need very warm weather to produce.
- Not enough water, sweet potatoes should never dry out. If there is not enough water through out the season the plant can be stress and will not form tubers. Sweet Potatoes need 1-2 inches of rain a week.
- Too much water, can also stress out the plants and they are not able to produce roots.
- Fertilizer, it is important not to use a high nitrogen fertilizer, too much nitrogen is for growing leaves and can cause the sweet potato to use its energy into producing leaves rather than tubers, It is best to use an organic granular fertilizer that is lower in nitrogen.
- The soil is too heavy, if the soul is not loose and friable the roots will not be able to grow and produce potatoes.
- if leaves are repeatedly eaten or removed, this will reduce the size of the underground tuber.
- Overcrowding is the plants are planted too close together they do not have enough space to produce tubers Make sure the slips are planted 12-18 inches apart.
pace: Sweet potato vines can spread extensively, so it's crucial to give them enough space torow. If the plants are too close together, they may not have enough room to produce large tub the recommended spacing guidelines for your specific sweet potato variety. sufficient Space: Sweet potato vines can spread extensively, so it's crucial to give them enough space to grow.
