More indoor plants

Remember those pineapple seeds I put in water to see if they would sprout? Well, two of them have! They are turning into teeny tiny plantlets. So that has taken two months. If I'm honest, I'm not sure what to do with them next. They're so small - almost microscopic - I don't want to plant them in case they dry up really fast and die. Do I leave them in the water, since pineapple plants apparently take in most of their nutrients through their leaves anyway? I have given them some new water this morning.

The pineapple top I planted has grown too. Its middle leaves have shot up, and are even getting a bit spiky around the edges. The ginger root it's sharing a pot with doesn't seem to be doing anything. I think that one might be a failure. Something to try again next year (if dh lets me...)

As for the avocados, they're all nice and tall now. I've pruned two of them back. The websites all say prune them back to about 6 or 8 inches once they get to a foot high, but I couldn't bring myself to cut them quite that much, they're more like ten inches. One is still too small to prune, and I'm waiting for the others leaves to grow a bit. In fact that one has leaves that are turning brown round the edges and falling off. Strange because the two it shares a pot with are fine! I suspect root damage - perhaps those pesky fungus gnats again - and will be pruning it this week to see if that helps.

You may wonder why pruning would help (if, like me, you're a novice), and the reason is that brown leaves usually result from water shortage. I can't water more because that will only make the gnats worse, so pruning the tree will decrease its water needs, meaning it will already be getting enough. That's the theory anyway!
