Finding out how to grow onions is always a good idea as they're used in so many recipes that you'll always make use of a plentiful supply from your garden veg patch. This is a great variety as it has a mild flavour that works well in all meals and it’s super easy to grow, which is always a bonus! 

You can directly sow these or start them off in a greenhouse – the best months are between January and April and again from September to October. Harvesting months are August and September. 

2. Tomatoes

Tomatoes can get affected by blight so we’ve chosen this variety as it’s one of the most resistant. It’s more of a bush type tomato plant which makes it easier to grow and it loves sunny spots. Producing cherry sized tomatoes that are exceptionally sweet and deep red in colour, you can start sowing the seeds in a heated greenhouse from January onwards. 

If you don’t have a heated greenhouse, then they will be fine sown outdoors from March to April. They will be ready to eat from late-June through to September. Find more tips on how to grow tomatoes in our guide. 

3. Aubergine

The best way to start them off is under glass from January to March and you’ll have beautiful aubergines from August until the end of October. They are great roasted in the oven, grilled on the best BBQ or enjoyed in salads and curries. You'll find more ways to make the most of your homegrown veg with our best BBQ recipes

The ‘Aquadulce Claudia’ has been awarded an RHS Award of Garden Merit, it’s a gardener’s favourite and a great choice if you’re new to sowing. You can actually sow these seeds from November to December if you can’t wait until January – just make sure you use a cloche to protect them from the cold. Or, sow in pots or seed trays from January to March and plant out once the soil warms up. They love full sun on rich fertile, well manured soil and germination is quite quick at around 10 days. 

5. Celery

This is a lovely looking celery as it has an attractive blush pink stem that looks great in fresh dishes. It is high-yielding and easy to grow. You can put the seeds in a propagator in January, and transplant once they are large enough to go into trays or individual pots. Celery does like to be moist at all times as this prevents the stems from becoming tough and stringy. It will be ready to harvest from August.
