Growing onions from bottom cuts (to be updated)

In the beginning of 2016, I've tried to regrow onions from the bottom cuts, although I am still trying to grow a full bulb -- or initially, a flower head -- I do have some thoughts and experiences learned so far.

This post would be tracking one bottom that only re-grows into one bulb.

Steps

1. Cut bottom from root about 1 or 2 cm.
2. Let the bottom dry for a day or two until you can see the rings separate.
3. Plant the bottom, the cut surface just at soil surface level.
4. Dig up and separate each new onion when big enough, then replant.

Thoughts

• Each set of rings grow into one onion.
• Cut each set of rings into section, so you don't need to separate later onion, if want to grow into bulbs. Need to experiment.
• Without drying, it seems to have higher rate to fail.
• Separation could damage if inexperienced.

Example (ongoing)

May 11, 2016, planted after drying, you can see separate rings. This bottom only has one set of rings.

May 19, 2016, 8 days after planting, the green is a few cm tall.

May 23, 2016, 12 days, 13 cm.

One sweet potato coming up

Last week, I bagged one sweet potato and one potato. The latter has a portion rotted, but sweet potato is doing well.

The very same sweet potato was actually suspended in a jar of water back in February, but it didn't go well, so I cut the rotted bottom and threw it into compost. Little did I know I would try again in a bag, but I didn't have any other sweet potato until I recalled there was one in the compost. I dug it out and it had grown some roots and slips, but all in white, because the lack of sun.

Anywho, I put some potting soil in the bag, which now is proved not enough, should be more so the potatoes wouldn't sit in wet soil. The sweet one on the top side of photo, the other on the bottom.

I added another layer of soil and replaced with a new potato, and kept its side of soil a bit of dry.

Not entirely sure if sweet potato can be grown in toweling method, but a quick search did get some results, although I didn't look into it.

I planned on harvesting sweet potato greens, I have seen they could easily take over a bed with their vigorous vines. The bag is really small, so I don't actually have any hopes for good tubers, but we will see.

I actually have another potato in a small container and it has five or six big stems, and it's at flowering stages, for which, I snipped of flower buds, even it doesn't seem to give much bigger tubers, just up to about 10%.

Also looking forward to ginger, which I've grown before about two years ago alongside turmeric. The ginger didn't have any new rhizomes even it had big leaves, but the turmeric produced a handful of rhizomes. They were grown in small box container, it's not a big harvest, but it's enough.

Right now, little beans are everywhere, some tomatoes are slowly growing. I don't trim most of the plants, so it takes really long time to set fruits, but I don't think I planted them for the eating or cooking.
