Sunflowers are great for gardens as they grow in any type of soil and are easy to maintain. However, you need to plant them in the Spring to prepare this sunshine in a vase for Summer.
If you live in a cold climate area, you can start sunflowers indoors about 2 weeks before the frost ends.
Sunflowers have a very deep taproot (especially if it is a giant variety) that does not do well when you transplant it from a pot to the ground, so i recommend using peat pots and coco pots indoors. Both can be planted in the garden where the sunflower can continue to grow! The great thing about these pots is that they will break down in the soil and actually improve the soil! Once you plant the seeds, water and cover it with a baggie or homemade greenhouse which is a repurposed water bottle. This keeps the seedling from drying out.
When it’s warmer outside, transition your sunflower to the outdoors by placing your little pot outdoors during the day for one week, and bring it indoors at night. This is called, “hardening” your plant and you can plant it outside afterwards.
