Sweet potato propagation update

sweet potato update

It took a few weeks for our sweet potato propagation technique to start showing signs of life, but now the new sprouts are popping up like they want to start a family of their own.

Hi Anna and Mark,

Well, I have 3 sweet potatoes and just bought a heating pad and will be trying to reproduce your method!

Could you please tell me what the temperature of your soil is?

The heating pad I bought has a 1 hour automatic cutoff. I disabled it :). But now I want to know how hot I should let the soil get so I am more or less like you.

I gather you keep the soil quite damp?

John --- You can see the nitty-gritty details in this post. However, unless you live a lot further north than us, it's probably too late to try it out this year. It takes about a month for sweet potatoes to start to sprout, and they really need to get in the ground within a couple of weeks after your frost free date. But you can always mark your calendar for next year.

Hi Anna and Mark,

Too late??!! Sounds like a challenge?

My local farmer friend tried them last year and they also rotted.

He controls the temp to 72. I have noticed my uncontrolled heat pad temps to be in excess of 85. I guess that might be too hot?

Since I build electronics, I guess I will start at 80 since this is a hot weather plant?

Lots of fun!
