I am on the Va/NC line zone 7B.I have had success growing Beauregards, Okinawas, and Covingtons, The best producers at my place were in that order.

A friend of mine gave me some sweet potato plants rooted and planted in soil before last winter. She told me to keep them and water occasionally and plant in April/May in North Texas. These little plants are about 6" high with multiple shoots from a center stalk. Do I plant the whole plant in a pot or cut off the shoots and plant? Confused? Thank you.

You can do both. More plants if you break it up into a few.

Hi; I know what a sweet potato slip is but what the heck is a sweet potato crown? All I can find on the internet is recipes for cooking not planting.

Crowns are the top sprouting part of a sweet potato. It should say slips too.

A slip should be 20 cm/8 in

Read the posting here in the New Zealand section - I just put a reply there about growing Sweet Pots.

If your sweet potatoes wont sprout it is because commercial growers spray them with a anti sprouting chemical. It can be removed buy giving your sweet potatoes a ascorbic acid bath for 15 minutes then rinsing. I use 2 tsp in a half gallon of water. you could also use crushed vitamin C pills.

Hi Santy, The fresh food markets (belconnen markets and fyshwick markets) have sweet potato. Most often they only stock the orange variety, but I have seen white and purple (purple skin, white flesh) there also. I am going to try to grow them this year, but keep in mind that they are not really suited to our climate!
