When is the best time in the UK to start gardening?

Beginning gardeners may have difficulty knowing when the gardening season officially starts and ends; here are a few general guidelines to assist them.

February may be cold but planting bare-root plants and perennial flowers is still achievable. July brings abundant harvests to your plots, flourishing vegetable gardening with its long days. Autumn ushers in an opportunity for pruning, tidying up, and preparing the garden for winter.

Winter gardening might not be your cup of tea, but that doesn’t have to stop you. Winter can still provide opportunities to clear out, tidy beds, remove perennials and weeds from borders, plant shrubs and climbers, and order seeds for springtime plantings.

Winter provides an excellent time for pruning fruit trees, such as apple and pear varieties. As these plants are dormant, the pruning process is less stressful than if done in the summer, when their full growth would have occurred. Furthermore, this season offers the ideal conditions to plant bare-root trees, hedgerows, or roses, provided that your soil doesn’t freeze up completely or flood completely.

If you have a vegetable garden, now is an excellent time to plant cool-weather crops that won’t survive the heat of mid- and late-summer, such as broad beans, cabbages, carrots, onions, peas, and salad mixes. Winter flowering bulbs such as narcissi, crocus, and pansies add colour, while hedges and climbers provide shelter to birds and bees during their hibernation phase. Try planting Cotoneaster sternianus hedges as dense evergreen hedges or Cirrhosa clematis varieties as beautiful climbers!


Gardeners take great pleasure in witnessing lush green growth and blooming plants, yet only experienced gardeners know when and how to plant their crops, whether that means vegetables, flowers, or perennials.

Spring marks a fresh start, with blooming bulbs such as daffodils and tulips welcoming in the warm sun while perennials and shrubs like hydrangeas and hawthorn shrubs sprout up to welcome them. Additionally, this month is ideal for sowing vegetable seeds such as peas and lettuce indoors as well as planting cold-season produce in greenhouses or cold frames.

Roses, hedging, and bare root trees should also be planted this month, provided they have been hardened off and your soil is sufficiently warmed up. Keen gardeners may consider sowing some annual flowers like bee balm, poppy, lupine, or baby’s breath indoors in preparation for when the weather warms up again.

Based on your climate, it might also be worth sowing carrots and other cool-season vegetables in the autumn for the best results in the spring. Seedlings each have individual preferences written into their DNA that dictate when and how they should flourish—only growing when given ideal conditions!


No matter if you are an experienced gardener or just starting out, having an understanding of the UK gardening seasons will enable you to get more out of your outdoor space. When planting trees, shrubs, flowers, or vegetables at specific times throughout the year, it’s ideal; don’t just rely on any old time!

By May 1, in milder areas of the country, typically frost-free conditions have returned, and planting of perennial foliage plants like Echinacea, Heuchera, and Geraniums, as well as patio plants, flowering annuals, and summer vegetable seeds such as courgettes, cucumbers, and French beans, is beginning. You should also set out bare-root trees. Hedge plants or rosebushes are now possible.

June is a busy month for any garden. Long days and hot temperatures make June ideal for sowing vegetables for the coming season, such as second-ear and maincrop potatoes, as well as salad leaves and spinach. Additionally, June can also be used to plant runner bean seeds for later harvest or cultivate squash inside or on windowsills.

Summer is the time of year when many plants put on new leaves and flowers to be pollinated by bees and other insects, drawing pollination from bees and other pollinators such as beetles. Summer also provides an excellent opportunity for lawn maintenance, trimming hedges, dividing perennials, mulching garden beds with organic material to retain moisture and prevent weed growth, and performing other general garden care duties such as trimming hedges.


Autumn offers the ideal opportunity for gardening enthusiasts. Soil remains warm from summer and nourished by autumn rains; days are shorter and temperatures cooler, causing less stress on plants than during spring, so they can settle quickly and thrive quickly.

Autumn is an ideal time for planting bare root trees, shrubs, and roses, as well as perennials and winter flowering shrubs like hellebores, camellias, clematis varieties, and magnolias. Additionally, evergreens, such as hardy evergreens, make for great hardiness. Evergreens and container displays featuring delicate blooms of cyclamen, asters, and pansies can also thrive during this season, plus salad greens like arugula, mache, and minutina can handle colder temperatures as well.

If you sowed crops during mid- or late-summer, now is a great time to harvest and prepare for winter by clearing away debris, cleaning greenhouses, cold frames, and tools, mending any trees or plant supports that need repair, and purchasing any seeds or bulbs you plan on growing next year. If your vegetable garden has been neglected in favour of all those beautiful flowers you’ve planted instead, now may be a good time to get back into it, as many hardy varieties can still produce all through winter if sowing now will ensure delicious homegrown vegetables right up until Christmas time!
