I started growing duckweed about a month and half ago. I had 3/4 of the pool covered, then all of a sudden it started going backwards, till it nearly all died. I thought the problem was no direct sunlight. I put it in a 100 litre container in the full sun, it seemed to stabilise then just rolled over and died. I have some in my guppy ponds that is dark green, with very little growth. What do you think I am doing wrong?
Any ideas will be much appreciated.
Hi Grassroots,
I've experienced the greatest success with duckweed when it has been in a tank with continuous recirculation.
You can kill duckweed by shading it, by feeding it too hard or if the water in which it is growing becomes too hot.
You can find more information that may be of help in my blog post on duckweed here.
