Autumn is a very important time in the garden with lots of preparation work for wonderful spring and summer gardens. For example are your bulbs sown – finish planting tulips as soon as possible. Also have you thought about ordering hedging for winter planting.
November is also a time for maintenance – check stakes and ties are secure on trees and climbers, empty pots of spent annuals, and rake up fallen leaves that could be sheltering slugs.
Also take care of what you have already – move containers of shrubs or winter bedding to a sheltered spot when conditions turn very cold, transplant shrubs that have outgrown their position, and prune rambling roses after flowering.
For more immediate reward think about planting winter colour such as heathers and trailing ivy.
