I need advice for pinching zinnia plant. The height of plant is about 6 to 7 inches up till now. Is it appropriate time to do it because couple of rain spells are also coming in lahore from time to time. They are planted in beds with full sun exposure. Also I want to know does this plant need any kind of fertilizer at this stage ? They germinated through seeds which I got from pride store in mid of April . Kindly suggest .
