Whether you’re looking to spruce up your garden or aiming to make the most of your outdoor space, award-winning seed supplier Dobies of Devon has produced this handy grow your own gardening calendar so you know exactly what to plant and when.

January

This is the month when your garden will likely experience some of the harshest weather of the year. Fortunately, the Winter Solstice will have passed and, as a result, plants will be trying to increase their growth rate to take into account the amount of light they receive.

Checklist for growing your own in January

• Plant bare-root trees and bushes, as long as the soil isn’t frozen
• Use a mild area of the garden to sow broad beans
• Start sowing seeds indoors for early crops — cabbage, cauliflowers, lettuce, salad onions, spinach and turnip are all great for this.
• Used a heated propagator to sow onion seeds
• Prune apples, autumn raspberries, currants, gooseberries, pears and quinces
• Harvest any citrus fruits, as long as they are mature
• Lift rhubarb crowns up using compost and transfer them to a cool greenhouse
• Plant garlic cloves in pots

February

While the first signs of spring may peek through, frost and snow are still likely in February, so vulnerable plants will still need protecting. Don’t worry though, your patience will be rewarded in the months to come.

Checklist for growing your own in February

• Plant fruit trees, bushes, canes and vines, as long as the soil isn’t frozen
• Chit potato tubers, with the plan to plant them out around six weeks after
• Sow cucumber and tomato seeds from the middle of the month, ready for them to start growing in a greenhouse
• Plant out garlic and shallots but only in light soils at the moment
• Early beetroot, broad beans, bulb onions, carrots, lettuce, parsnips, peas, spinach and summer cabbages can be sowed outside under cloches this month, if you have light soil and live in a mild area of the UK
• Plant Jerusalem artichoke tubers
• Use a garden fleece to cover strawberry plants to encourage early fruiting
• Plant summer-fruiting raspberries
• Harvest Brussel sprouts, harvest leeks and sprouting broccoli

March

The beginning of spring also represents the start of sowing in your garden. Just be aware of the unpredictable British weather — everything should be covered in fleece if you hear severe weather forecasts, to prevent your early spring work being undone.

Checklist for growing your own in March

• Plant bare-root fruit trees — it’s the last chance to do so in the calendar year
• Prune any hardy fruit trees present in your garden

November
