Q.How to grow pompom marigolds from seed
How to grow pompom marigolds from seed with only a small unheated plastic greenhouse? I would like to grow yellow pompom marigolds from seed. I’ve never grown anything from seed before and I have recently bought a small plastic greenhouse with just a rack of shelves but no heating.
I would suggest starting your seeds indoors. Most seeds need quite warm temperatures for germination.
Always follow the directions for sowing your seeds from the back of the seed packet.
I start nearly all my garden from seeds, and I think you will enjoy the process. Marigolds are a great plant to start with.
Here are some links to help you get started.
