Once the temperatures rise towards May, you can sow your seeds outdoors. Space them 60 cm apart and sow two seeds per hole. After a few weeks, you can simply pull out the weaker seeds and allow the stronger plants to continue growing. It takes approximately eight to ten weeks from sowing to harvesting.

Hello, I’m Pete and I’m currently based in the west of Scotland, in a small place called Rosneath, where I’m exploring my garden adventures. I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
