I got a few marigold plants planted in the ground. A lot of them died, two are surviving somehow.

Earlier these two seemed to be dying also. Their leaves are turning white or are they white spots ?

Next, they turned all green, new branches came out and buds and a flower too.

Now the leaves are all turned white again.

What is this? Why are they turning white again after recovering from that? I water them everyday, they get enough light also.

  • Where are you in the world and what have the day/night temperatures been like in the last month or so? Is the white stuff like a deposit on the leaves that can be wiped off, or in the leaf itself?

  • I've grown quite a few marigolds. Haven't come across anything like this. Temperature for sure isn't to blame. Tell me a little bit about the leaves. Do they have a crispy texture to them? Those that are turning white. Do they appear to be on the verge of drying out? Do you water them at the base or from overhead? What kind of fertilizer do you use? How often? Was there anything else planted before in place of the marigolds? If yes, what? Feb 23, 2019 at 20:24

Our marigold leaves (in India) have been turning white too. It is a form of fungus. Spraying NEEM OIL is suggested. Even the soil may need to be treated with neem. If things still don't get better, may have to just discard the plant. And remember to treat the soil before planting new.

  • Thanks for letting me know. Those have died and I haven't planted anything there since then. However I'll keep in mind your suggestions if it happens next time.
