With a Christmassy name like 'Candystripe', I knew this flower variety had to be included in the Christmas advent calendar. Cosmos is an absolute must-have in your garden. A gorgeous cottage garden favourite. Cosmos are half-hardy annuals- that means they grow, bloom and set seed and die all in one year, meaning that you need to sow fresh seed each year.
The good news is that these are quick and easy to grow from seed, flowering in as little as 12 weeks. These are brilliant in borders and also can be planted in containers or pots too.
Sow Cosmos seed into module trays or pots, leave on a warm sunny windowsill until germinated and then move into a zippy or greenhouse and grow under cover, watering occasionally to ensure the soil doesn't dry out.
Sow in early spring indoor, or direct into the ground (simply poke a hole in the soil, pop the seed in and cover with soil and water) in late spring all the way through to late May.
Once your Cosmos seedlings have two set of leaves, you can 'pinch them'. Watch this video for guidance on how to 'pinch' them for bushier plants with more flowers.
In May, harden them off for around week by placing in either an open cold frame or on a patio, before planting the Cosmos plants out where they are to flower.
Do share any pictures of your Cosmos with me @therosepressgarden- I absolutely love seeing your photos!
