10: What to do in the garden in October
With the dark nights getting longer and temperatures starting to take a turn, this is the month you’ll notice the leaves turning from green to orange in preparation of autumn.
This is a great time to add your garden waste to the compost heap or to use leaves to start making leaf mould. There is a potential for frosts in October, so be sure to bring tender perennials indoors to shelter them from frost damage. There is also the potential for strong winds and increased rainfall in October, so it’s worth keeping an eye on the forecast.
October is the time to plant trees and shrubs, start by removing all traces of weed then. preparing the soil with organic matter or a tree and shrub planting compost.
Plan ahead for next year by getting your spring bulbs planted from now but save the tulip bulbs for November!
