What to do in the garden in September

Lisa Garden on 01-09-2016

As the sun dips lower, things get busy in the garden again. The autumn harvest needs gathering in, and late summer flowers are at their best - so gear up and get stuck in to this month’s jobs around the garden.

General tasks:

Clean the greenhouse after clearing spent tomato and cucumber plants, washing the glass thoroughly and disinfecting benches and pots.

Feed established lawns with low-nitrogen feed to encourage plenty of root growth ahead of winter.

Ornamental garden:

Keep up with dead-heading, removing faded blooms to encourage flowerbuds to keep coming until the first frosts.

Plant paperwhite narcissi in pots of free-draining compost ready to force for sweetly-scented flowers this Christmas.

Plant new shrubs, trees and perennials while the soil is still warm and rain is likely, so they’re well established before winter sets in.

Kitchen garden:

Direct sow hardy salad leaves to harvest through autumn and winter, choosing cold-tolerant varieties like ‘Winter Density’ lettuce, mibuna and pak choi.

Bring pots of basil indoors and pop on a sunny windowsill where they’ll stay productive for weeks longer.

Plant Japanese onion sets to overwinter as seedlings and get a head start in spring, giving you bulbs weeks earlier than spring-sown varieties.
