What to grow in your greenhouse in Autumn

It’s a quieter time of year in the garden, but a greenhouse offers an ideal, sheltered space for many plants to thrive. If you’re wondering what the best things to grow in a greenhouse in the Autumn are, then we’ve got some tips for you.

As the days shorten and temperatures begin to drop, there is still plenty of opportunity for growing greenhouse vegetables, herbs and plants.

There are a few things you can do to prepare your greenhouse for Autumn. One of the biggest things to consider is the lack of natural light, so give the glass a clean and remove anything that may be blocking the sunlight from getting into your greenhouse. You should also clear out any spent summer crops before sewing your new seeds.


Root crops are ideal for growing in your greenhouse during the Autumn. Try carrots, beets, radishes and kohlrabi.


Some hardier salads, such as rocket or mizuna cope really well with autumn temperatures. You can sow the seeds in trays or pots of compost and then transfer the seedlings to larger pots.


Sweetpeas can be sown in October or November. Soften the seeds first by putting them between two sheets of moist kitchen towel. When they begin to sprout, sow individually and overwinter the seedlings in your greenhouse or cold frame.


More hardy herbs, such as basil, coriander, dill, chives, rosemary, thyme, oregano, mint and parsley can tolerate cooler temperatures and work well in a greenhouse. Plant seeds in pots and leave in the sunniest spot in the greenhouse. Prune your herbs regularly to encourage healthy growth. You could also consider adding lighting to your greenhouse, or using one of our S-Series mini greenhouses.


Microgreens that are tolerant of slightly cooler temperatures are perfect for growing in the greenhouse in Autumn. Choose spinach, beetroot, broad beans, arugula or radishes. Plant the seeds in shallow trays with nutrient-rich soil and good drainage.

The microgreens will need good sunlight, consistent temperature and humidity and good ventilation to prevent mould. Water little and often, ensuring the soil is evenly moist.

Microgreens are ready to harvest in just a few weeks, when the first true leaves appear. Snip them just above the soil level and enjoy.

There are plenty of things you can fill your greenhouse with during the Autumn. So have a clear out, clean the glass and start planning what you’ll sow.
