Christmas Advent Calendar Wrap Up

So you’ve received a 2020 TRPG Flower Seed Advent Calendar and opened up seeds from each day… now what to do next? Well hold tight as not all of the flower seeds can be sown straight away. But I promise it’s worth the wait. You have a very exciting few months ahead of you- sowing and growing all these seeds into beautiful flowers! Your garden/allotment/Pots/borders are going to look amazing come summer and you will be able to pick bunches of flowers to bring indoors or share with friends, or just admire your lovely garden! Whether you are a new beginner or a long-standing green-fingered expert, I hope the next few months bring you as much joy as I get from growing a beautiful garden from seed.

This post is hopefully going to give some helpful hints and tips on how to grow your seeds. Plus if you have any particular questions then let me know by dropping me an email or message me on Instagram @therosepressgarden. I’d also love to see all your pictures of you sowing and growing your seeds, and of course all the finished results too!

Sweet Pea ‘The Blues Mixed’                           

A Monet style mixture of flaked colours. Sow this winter in module trays and then transplant into pots as they get bigger. Pinch out the seedlings for branching, and therefore more flowers! Keep watering, feeding and deadheading throughout the season for best results.


Ammi Majus Graceland

A real unique show stopper, suiting baskets and containers. Produces masses of bicolour white/yellow flowers with a strong scent. Sow Feb-April, 2 weeks at 15-18°C. Higher temperatures supress germination. I’d recommend planting in a pot to keep on your summer table to enjoy the scent outside!
