When to plant vegetables: a guide to sowing and harvesting vegetables

Want to grow your own vegetables, but don't know when to start sowing and harvesting your crops? Then here's our handy Guide to Sowing & Harvesting Vegetables.

WHEN TO PLANT VEGETABLES

It's important to sow your vegetable crops at the right time of year – whether it's directly outside in the ground or indoors with heat – and to harvest them at the right time, when they're at the peak of their tenderness and taste.

The majority of vegetables will be sown in Spring (March to May) however some, such as Broad Beans, may require to be sown a little earlier depending on the weather/temperature conditions. Harvesting usually starts in mid-Summer however some vegetables will require harvesting a little earlier - such as Beans, Carrots, Radishes and Potatoes - and some a little later – such as Beetroot, Brussel Sprouts, Cabbage, Leek and Parsnips. The later harvesting vegetables may continue into the next year – January/February – depending on growing conditions.

Note that certain vegetables will require sowing inside to start propagation taking hold before moving outside. Vegetables such as Tomatoes, Sweetcorn, Cabbage and Marrows will require this step.

Read our detailed planner below for a breakdown of which vegetables require sowing, moving and harvesting and at which points of the year (click on a crop for detailed growing information).
