This is my first try at growing sweet potato slips and I’ve read conflicting advice on when to ‘harvest’ the slips. Anyone have any advice?
ASAP It's already a tad late for 9b. They are warm/hot weather plants. Get a super sharp knife and slice off each slip with a little bit of the potato skin and meat. Just a little bit, plant and keep moist.

Good looking slips. Your area is ideal. I grow in 5B and the season is usually a bit too short. Leave them in the ground as long as possible, I am limited by frost probably the end of September. I cut the slip leaving a bit of the mother potato. They are great survivors and spread out considerably. Mark the seed slip so you can dig at the center of the mass in a few months. Rabbits love them so if you have some put a fence around the bed.

Luckily, I have a wall enclosing my backyard, so no 4 legged creatures. You’ll see angry Mike come out in the fall when I overseed my grass and the rats with wings swarm my yard though.

When you say, ‘Mark the seed slip...’ what do you mean?

Put a stake marking the slip for later finding. The vegetation takes over and the harvest is around the seed slip in about a foot diameter. A good crop is around 5 pounds from one slip. You may get more being in a warm 9 zone.

Curious where you all get slips? I can only find starter plants or bare roots and they seem to be slow starters. We will see at harvest time I guess, but I'd love to find slips (seed potatoes?).

I just grew mine from a store bought sweet potato. Cut them in half and put them in water.

Sweet potato slips were produced from a purchased supermarket tuber. The potato was placed in water,and light and allowed to grow for about a month. They were then placed in a growing pot and will allowed to grow for about a month. They will be about 4 inches high and then will be planted outdoors when it is warm about 24 May in my area, Zone 5. Even these small slips will grow without further pot growing. I expect 3 to 5 pounds from each plant depending much upon warm weather. Harvest is late Fall.

Good to know, I wander if these will produce better than bare root starters?

Any slip grows. Basically a slip is a bare root.The slips grow slowly at first then they want to take over after getting established. When I grow the slips I leave a bit of the mother potato, for no good reason.
