September Gardening Tip: Bulb Planting & Autumn Prep in Hampshire
September is the best month of the year for productive garden work. The soil is still warm from summer, the days are getting shorter, and there’s a satisfying urgency to getting things planted before the cold sets in. In Hampshire, September work pays dividends all the way through to next summer.
Plant Spring Bulbs Now
Tulips are best planted in November, but daffodils, alliums, crocuses, muscari, and fritillaries all go in from September onwards. Plant at two to three times the bulb’s depth in well-drained soil. Layer different bulbs at different depths for a long season of colour.
Renovate Your Lawn
September is the prime time for lawn repair. Scarify out the thatch, aerate compacted areas with a hollow-tine fork, overseed bare patches, and apply an autumn lawn feed (high in potassium, low in nitrogen). The warm soil and autumn rain do the rest.
Move Tender Plants Under Cover
Before the first frosts arrive, move tender plants like cannas, dahlias, and half-hardy perennials into a frost-free greenhouse or shed. In Hampshire, the first frosts usually arrive in October.
Helyers’ September Tip: September is ideal for planting new trees, hedging, and shrubs. The warm soil helps roots establish before winter, giving them a head start for spring growth.
