A Brief Guide on What to Grow in Your Greenhouse

Whether you’re a green-fingered genius who enjoys gardening as a pastime or you simply want to become more environmentally friendly by growing your own food, a greenhouse is an incredibly useful structure to appeal to both. But, if you’re unsure of what exactly you can sow and grow in your greenhouse throughout the year, we’ve put together a blog to explore what you grow year-round.


Winter can be a tricky time of year to grow things due to frosts and cold temperatures. However, there are still some vegetables you can sow in winter at the start of the year leading into spring. These are the crops you should consider sowing in your greenhouse in winter:

  • Spinach
  • Cabbage
  • Lettuce
  • Broccoli

These plants endure lower temperatures better than other crops and are able to be transferred outdoors 3-4 weeks before the last frost date. But, you can use your greenhouse to sow and grow them earlier without frozen ground to hinder their growth.


With the arrival of spring comes the birth of life and prime planting season. This time of year, you’re able to grow more tender plants in your greenhouse including:

  • Melon
  • Cucumber
  • Squash
  • Pepper

Plants like these will require a warmer and controlled environment with at least eight hours of sunlight in order to thrive. So, aim to sow them in your greenhouse in mid-Spring to avoid frosty conditions that could kill your crops.


Once your spring crops are transferred outside, it’s time for your bright and beautiful summer crops to be sown. Heat-loving plants will thrive in your greenhouse – here are some to plant at this time of year:

  • Aubergine
  • Tomatoes
  • Chilli peppers

However, if you’re experiencing a heatwave in the summer, it may become slightly too hot in your greenhouse, inviting mould and mildew inside as well as helping to dry out any soil. Consider investing in a vent kit to keep your plants at a comfortable temperature to ensure they don’t shrivel and die.


When the cooler weather starts to return, finish with your summer plants and start your autumnal crops. These plants could be:

  • Kale
  • Peas (snap or snow)
  • Turnips

You might notice that growth this time of year will be slower, but be patient and they’ll be ready in time for hearty and comforting roast dinners during the winter months.
