Here you will find a list of everything I’m sowing this year in a weekly format. I will soon update with varieties too. You will notice quite a bit of repetition with some veg, in particular salad leaves and carrots. This is to ensure successional cropping of these veggies and so they are not all ready to harvest at the same time (who needs 10 broccoli ready all at once?!)
Early sowings will need extra heat and, more importantly, light. Onions, Peppers, Leeks, Tomatoes and Pumpkins will all be started on a heated windowsill propagator. The other early sowings will be started indoors but without extra heat.
The only seeds that will be direct sown are carrots and parsnips. Everything else is started in trays/pots indoors or in the greenhouse.
Come April many plants can be moved to the unheated greenhouse but you need to keep an eye on over night temperatures and take action for any cold nights. Make sure to have a roll of fleece handy. Temperatures above 10c over night are fine for tender plants, below 10c you need to bring them indoors or run a greenhouse heater. Above 5c is fine for hardier seedlings such as peas, salad leaves, brassicas etc. Below 5c these plants will need fleecing or bringing indoors.
By mid May we are usually safe enough to start moving tender plants outdoors. Hardier plants can be planted out earlier but may need fleecing in cold snaps.
By August sowings have slowed down but make sure to sow in late summer/autumn for overwintering.
I hope this is helpful, Steph 🙂
