These are my first lotus plants and I dont know much about them. I have grown them from seeds. Roots are in a container filled with soil,organic compost and gravel. This pot is inside a big container filled with water. Also its a rainy season here with temp ranging between 25 degree celsius to 30 degree celsius.

From couple of days leaves started to rot. Is this normal behaviour for lotus? Or i am doing something wrong ? How frequently i should change water in the container? I last changed it around 4-5 days back.

    Could be overwatering. – J. Musser Sep 1 '17 at 17:06
  • ;)... Have you seen fungus gnats on the leaves at all? – J. Musser Sep 1 '17 at 17:13
  • Do you have a recirculating pump? – stormy Sep 1 '17 at 22:05
  • So this is in a large pot of some kind? What kind of water are you using? Have you considered putting fish in this water? The lilies should keep the water from overheating. What have you added to this system? How are the roots and soil doing in their pots in the pot? I've done this so many times without fungus problems. Is this pot out of doors?? – stormy Sep 1 '17 at 22:09
  • I wish I would read the questions more closely. Have you fertilized at all? What kind of compost? Was this compost decomposed or raw? Do change out the water or better just stick a hose in your system and allow it to overfill and replace some of the water. Do this every day in lieu of recirculating. This adds oxygen to the water. – stormy Sep 1 '17 at 22:13

I suspect black spot fungus and you have a lot of necrotic lesions on those leaves sadly.

Treat with Neem oil initially. And then try a fungicide if that doesn't work.
