THESE SEEDLINGS NEED A LITTLE EXTRA WARMTH, SOW THEM INSIDE AND LET THEM GROW ON INSIDE
Towards the end of March, if you have space indoors or a heated greenhouse, you can start to think about sowing tomatoes to grow on undercover. Last year I succumbed to social media pressure sowed my tomatoes around mid-March, but next year I will wait until at least the 3rd or 4th week of March. Space is a consideration, as they grow so fast so will probably need potting on a few times before they move to the greenhouse. If they become pot bound it can stunt their growth, so it’s best to delay sowing for a few weeks and have healthier plants, if you can resist! If you plan to grow tomatoes outdoors, wait until at least mid-April to sow.
If you started your peppers & aubergines indoors earlier in the year, hold back from transferring to the greenhouse just yet if the forecast is 5 degrees celsius or lower – I try to keep these indoors until the risk of frost has passed. These plants love warmth, so keep them inside if you can, and pot them on if needed so they don’t become root-bound.
