There’s a rhythm to the garden centre year that experienced gardeners understand instinctively, and beginners pick up the hard way. Buy at the wrong time and you’ll either find bare shelves, overpicked stock, or plants that cost twice as much as they should. Buy at the right time and you’ll find quality, choice, and often much better value.
Here’s a rough guide to what’s worth buying — and what to hold off on — at each point in the year.
January and February
Most people skip the garden centre in January, which is actually one of the better times to go. Bare-root trees, roses, and shrubs arrive in quantity from late December and are at their best before the end of February. Bare-root stock is cheaper than containerised plants, establishes well, and the selection is often excellent before the best varieties sell out.
This is also a good time to buy seeds — the new season’s catalogues are in, and you’ll find the full range before the popular varieties go. Seed potatoes and onion sets typically appear from late January.
March and April
The busiest months of the garden centre year. Bedding plants start arriving in earnest, though early April bedding is often pushed before the last frost risk has really passed — worth knowing if you’re in the north of England or Scotland. Hardy perennials come into excellent stock from March, and this is the best time to buy summer-flowering bulbs: dahlias, gladioli, begonias.
Compost sells fast at this time of year. If you use a lot of it, buying in bulk in February before the spring rush is consistently better value.
May and June
The peak of the garden centre season. The widest range of plants, the best display, the longest queues. Tender bedding — petunias, geraniums, busy lizzies, fuchsias — reaches peak availability once the frost risk is past (roughly after the Chelsea Flower Show for most of the UK, traditionally). Container and hanging basket plants are at their best.
Garden furniture, barbecues, and outdoor accessories are all prominently displayed and well-stocked. If you’re planning summer purchases, buying in May before the good-weather surge in June means better choice and sometimes better pricing.
July and August
Midsummer is when garden centres start discounting. Bedding plants are half price or less by late July — often perfectly good plants that just need deadheading and a feed. Perennials and shrubs are also frequently reduced, and while root establishment in summer heat can be challenging, the savings are real.
This is also the time to buy and plant autumn-flowering bulbs: nerines, colchicum, and autumn crocus. And it’s worth checking what’s in the seed section — summer sowings of biennials like wallflowers and foxgloves pay dividends the following spring.
September and October
Autumn is arguably the best time of year to plant most things, and garden centres stock accordingly. Hardy perennials planted in autumn establish before the ground gets cold and are away early the following spring. Shrubs and trees planted from September onwards can be watered in naturally by autumn rain. Spring-flowering bulbs — daffodils, tulips, crocuses — arrive in September and are best planted between October and December.
November and December
Christmas stock dominates from November, but the practical gardening section still has things worth buying. Bare-root stock of roses and fruit trees starts arriving from November. Amaryllis and paperwhite narcissi for indoor winter colour are well-priced at this time. And December is actually an excellent time to plant bare-root hedging — beech, hornbeam, hawthorn — when it’s cheap, widely available, and will establish well over winter.
