It is the first of June. I can hardly believe it. We have been a littler cooler on average this spring.
The sweet potato slip above is one of thirty one that I planted in the garden today. They have been “hardening off” outdoors during the day in 4″ pots of potting soil for a couple of weeks. I am able to plant them without disturbing the roots at all by this method.
The sweet potatoes in the plastic tub above produced all the slips that I potted up. The tub is setting on a heating mat (set for 80F) in the basement under a high intensity LED grow light. Some start sweet potato slips in a jar with the potato supported by toothpicks. I have had much better results with the tubers horizontal in a tub of garden soil.
When the slips get to around 4″ tall, twist them off of the parent. This year I placed some in water until they developed roots, then put them in pots. Others, I placed in the pots directly. The pots were all kept well watered by keeping them in restaurant bus tubs with an inch or so of water in the bottom. I couldn’t really tell the difference between the two methods. Next time, I think I will skip placing them in water first.
The ability to propagate these is a gift from God. I am grateful for all the plants that He created to be food for us! He is truly Jehovah Jireh, God our provider!

Fascinating! I didn’t know how this was done. It sounds much more affordable than buying new sweet potatoe plants every year.

It takes a while and some attention, but the price is right.

And you’re doing science! Two tests, one variable, check the results. And if it’s the same, take the easy path.

Life is all fun and games for me, Steve. Today at work I was doing drop testing on electronic assemblies, one meter to concrete. When I was in engineering school, it was pretty hard to tell from physics and science.
