I start my 'slips' in mid to late May, depending on the weather. I usually do not plant the rooted slips until second week of June.
I take the saved sweet potatoes from previous year, and place them in the soil covered just slightly, potting soil works best if the soil is not super loose. I have been putting mine in a raised bed near a water barrel and water frequently. Then as the slips grow I break them free from the potato and place them in a glass jar and keep them watered. I have been told it is best to cut off any of the potato that breaks with the new slip, apparently having part of the potato interferes with the plant forming strong multiple roots.
Once the roots get established, and it will not take long, a week or so, then I plant the slips in a prepared raised bed just for sweet potatoes. They love water but do not like to stay in water so need good drainage.
There is a place in TN that I ordered some slips some years back. I also found at Lowe's a few slips this year. But if you are still interested in planting some come next April, give me a ping and I will let you know how my potatoes are looking for making new slips. IF they look good I would be pleased to send you some.
Ok. Thanks, I’ll try to remember that if I decide to plant them. That’s so nice. Thanks again.
