The Beaumonts Seasonal Gardening Calendar
A well-tended garden follows the rhythm of the seasons. This calendar gives you a clear picture of what to do each month — from the first stirrings of spring to the quiet preparations of winter.
Spring (March – May)
March is the time to start sowing hardy annuals under cover and to divide established perennials before new growth takes hold. Clear away any remaining winter debris and apply a balanced slow-release fertiliser to borders. In April, direct-sow hardy vegetables such as carrots, parsnips and beetroot once the soil has warmed. Harden off any seedlings started under glass before planting out. May brings the last frost risk — hold back tender plants until the middle of the month. Stake tall perennials early, before they need it.
Early Summer (June – July)
June is peak planting season. Deadhead roses and repeat-flowering perennials regularly to extend the display. Water deeply and infrequently rather than little and often — this encourages deep root growth. In July, keep on top of weeding before plants set seed. Harvest courgettes, beans and salad leaves frequently to encourage continued cropping. Take softwood cuttings from shrubs such as lavender, salvia and fuchsia.
Late Summer (August – September)
August is a month of abundance. Harvest regularly, water consistently and feed container plants weekly with a high-potash feed. Begin collecting seed from open-pollinated annuals and perennials. September is the ideal time to plant spring bulbs — tulips, alliums, narcissi and crocus. Sow green manures on bare vegetable beds to protect and enrich the soil over winter.
Autumn (October – November)
October brings the first frosts. Lift and store tender tubers — dahlias, cannas and begonias — before the ground freezes. Plant bare-root trees, shrubs and roses from mid-October onwards. November is the time for structural work: pruning deciduous trees and shrubs, laying new turf, and improving soil with well-rotted compost or manure.
Winter (December – February)
December and January are quieter months, but there is still work to be done. Clean and sharpen tools, order seeds for the coming year, and plan any changes to borders or layout. In February, watch for the first signs of growth — snowdrops, hellebores and early bulbs. Begin chitting seed potatoes and sow onion seeds under glass towards the end of the month.
