|Zinnias need plenty of sunlight when grown in the garden so you will need to provide as much light as you can, which probably means using supplemental light beyond what you would get through a window or else growing them in a greenhouse. They will need to be potted up periodically until they are into sufficiently large pots to accommodate blooming sized plants as well. Finally, you will need to fertilize and water them regularly so that they are in vigorous healthy growth.
