Water Gardening: Hyacinths in my pond, blooms, 1 by Dinu

I'm attaching a picture I took a few weeks back. I had allowed these hyacinths to spread and cover the surface so that it can keep the thread algae down and it seemed to work. There was just some 20% area of water visible. The huge leaves of the water lily also covered. I have also noticed that the ones that are freely floating with roots hanging down flowered less but the ones that rested on the rocks (placed) higher up near the surface seem to flower more quickly and those also had larger leaves. It seems to bloom in warmer weather. It is summer here with mercury touching about 36 Celsius max. Min. is around 21C. The peak of summer in this part of India will see 37-38 C. It will be in May. In June, the monsoon arrives and cools things down. My pond has a sort of bog area on the two sides having a shallow level. I don't take any special care of the pond but I keep removing the hyacinths every now and then as it is a very invasive type here and a quick spreader too! Two weeks ago, I removed >50% of what you see in this picture now.
