How to fertilize Chocolate Cosmos
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Chocolate Cosmos after it doubles in size or once a year—whichever comes first.

Help! How do I save him? This is Achilles. I took him after my mom failed to take care of him. He was removed from the soil by cats and was incredibly droopy. Besides that there is no visible damage. I am scared that he will die. I had to plant him very low into the soil to give him a chance to get light so I don’t know if that is bad.

This cosmos flowers are not doing well. Are they not getting enough water or too much water? It was blooming when I adopted this plant a month ago. #MexicanAster

What the freak are these things? Hey all, does any know what these are and how to get rid of them? Whatever they are killed off my sunflowers and are working on my wild flowers now help me please lol no seriously any help would be great! I've been putting cinnamon on everything and coffee grounds, it kicks the ants out short term but nothing else 😩 Update: 6 days later and no still little creepies!! 🙌🏽 I wiped them off with rubbing alcohol. After that I made a solution of alcohol, dawn dish soap & water in a spray bottle (I didn't measure 😅, just eyeballed) and sprayed all the leaves on all my plants. So far nobody's dead and everyone is thriving bug free. I'll keep this solution & my cinnamon on hand at all times! Thanks All!!

if you think it’s dead, it’s probably not. just trim back the dry foliage and it’ll come back!
