When to plant vegetables
Whether they’re sown directly outside in the ground or indoors with heat, it’s important to sow and harvest your vegetable crops at the right time of year when they’re at the peak of their tenderness and taste.
The majority of vegetables are sown in Spring (March to May) however some, such as broad beans, may require to be sown a little earlier depending on the weather or temperature conditions. Harvesting usually starts in mid-Summer. However, some vegetables will require harvesting a little earlier, such as: beans, carrots, radishes and potatoes. Some are a little later, like beetroot, brussels sprouts, cabbages, leeks and parsnips. The later harvesting vegetables may continue into early the next year depending on growing conditions.
Note that certain vegetables will require sowing inside to start germination before moving outside. Vegetables such as tomatoes, sweetcorn, cabbages and marrows will require this step.
