How to sow cosmos seeds
Sophie said: “Sow the seed. I have tried two method and both have been successful. Either surface sow and cover with soil, or pop them in a 1cm hole and cover.”
She claimed these methods have been “so successful in fact (she is) now drowning in cosmos seedlings.”
Sophie went on: “Make sure you keep them moist not soggy.
“I use a water sprayer and carefully overhead mist them.
“Once germinated I pop mine in the zippy greenhouse to stop them getting leggy.
Sophie recently detailed a plant to sow in your garden, calling the hardy climber “incredible”.
Sophie, who is a mum to three boys, suggested sowing Spanish Flags to her followers.
The plants are also known as Ipomoea lobata and come in red and yellow.
