I was sent a second batch of seeds for free but I held onto them until just about three weeks ago. I soaked them for several days, planted them in compost and then left them in a warm cupboard. I had to use ice cream pots which seem to work really well. Six seeds were planted in each. The right one was always kept indoors until sprouting. For the left one I wanted to see if they would sprout in outdoor temperatures. After a week there was nothing so I brought it in and then they started to sprout.
I've been putting the seedlings outside on sunny days and bringing them in during the winter. It's still a bit cold here in the evenings and I don't want to impede growth. Animals also LOVE these little Moringa seedlings and there is no way I'll leave them outside unguarded during the night.
For anyone that wants to know why I'm so interested in this plant, take a look here. The nutritional properties of Moringa species are similar. My goal is to grow them as a tuber in the summer and then dig up and store for the winter. We'll have to see how it goes!
