Sweet Potato : Georgia Jet
Cold tolerant and can be successful in areas with short growing seasons
In spite of the sweet potato's Southern reputation, Georgia Jet is cold tolerant and can be planted successfully even in areas with short growing seasons. Its sweet, moist, mildly fibrous, and bright orange flesh make it a classic sweet potato perfect for baking. Our 2011 highest yielding variety.Convolvulaceae Ipomoea batatas
Soil PH: 4.5-7.0, Ideal 5.5-6.5
The Sweet Potato does better in poor soils than most other crops, but (as is usually the case) better soil will give you a larger crop. The ideal soil for Sweet Potatoes is a rich, deep, well-drained sandy loam that retains moisture. It should be fairly acidic, as this reduces disease problems. If the soil is poorly drained there is a risk of root rot. Heavy clay soil isn't good as it may produce slender roots.
Standard Mix, 5 pound(s) per 100 sq. ft., in top 8in of soil, 1 time
Like most root crops, Sweet Potatoes need plenty of phosphorus and potassium, but not a lot of nitrogen, which encourages the growth of foliage rather than roots (and can even result in inferior roots). Incorporate 5 lbs. of Standard Mix into your soil to provide them with these nutrients.
Compost (N), 3 inch(es), in top 8in of soil, 1 time
Sweet Potatoes like organic matter and compost will be beneficial no matter what type of soil you have. It will help to lighten a heavy clay soil, help a sandy one retain moisture and supply nutrients in all situations.
If your soil is heavy or compacted it is a good idea to loosen it by double digging and adding plenty of organic matter (or you could build raised beds and import soil).
