Plant now for the best spring display: autumn bulbs and perennials for Kent and Sussex gardens

There's a common misconception that autumn is when the garden winds down. In reality, it's when the most important planting happens. Bulbs planted now will establish strong root systems through the mild Kent and Sussex autumn, ready to burst into growth the moment temperatures rise in late winter.

On chalk soils — the South Downs, North Downs, and the downland villages of East Sussex — autumn planting is especially effective. The free-draining soil never becomes waterlogged, so bulbs establish without rotting. On heavier Wealden clay, plant on a slight ridge or add grit to the planting hole to improve drainage.

Tulips are best planted in November, after the first cold snap, to reduce the risk of tulip fire disease. Everything else — alliums, narcissi, crocus, muscari — can go in from September onwards.

For perennials, autumn is ideal for dividing and replanting established clumps. The soil is still warm enough for roots to establish before winter, and the cooler, wetter weather reduces transplant stress. Hardy geraniums, sedums, and ornamental grasses all respond well to autumn division.

At Argent Garden Designs, we always include a strong autumn-planting layer in our planting schemes — it's the most cost-effective way to create a garden that looks spectacular from late winter onwards, with almost no additional maintenance.
