Q.How To Take Care Of Zinnia Plants Grown In Small Pots?
I bought a zinnia plant which was already grown in a small pot. I kept the plant in a good sunlight place and good air circulation. It bloomed 3-4 flowers but, after 4 days plant started drying up like in the photo. I’m not sure what to do next. I just cut off the grown and dried up flowers alone for now. Please let me know on: a. What is the next step that I should take? b. How often should I water ? c. What’s the ideal pot size to grow zinnia ? d. What should be the routine care for it ?

I would get it in a pot a couple sizes larger (regular potting mix) and water it every day unless it is still moist. Zinnias in pots dry out quickly. If you have a nice garden space, you also could plant it. If in the ground, it will drop seed at the end of summer and should return next year. The kind you have do better inground.
