I’m so glad I live in a world where there are Octobers
L.M.Montgomery: Anne of Green Gables
For the avid gardener you’re spoiled for choice, especially with the mix of sun and rainfall in September promoting growth – the lawn seems to be growing as you look at it. A good place to start if you haven’t prepared it for winter and next year is to aerate and scarify early in the month.
On to borders, it’s time to cut back faded herbaceous perennials and to lift and divide overcrowded ones. Which means it’s also a good time to visit the garden centre and find new plants to add to next year’s border canvas, with the soil still warm and moist.
Planting spring flowering bulbs should be high on your list but wait until November to plant tulips. In some warmer regions dahlias and cannas may be overwintered in the ground, but for most of us it’s time to lift the tubers and rhizomes when the first frosts occur. You can be planting wallflowers, Primula, winter pansies and Viola, Bellis and other spring bedding plants in the ground or pots. Climbing roses could do with a prune now along with hedges.
Tender plants in pots can be moved into the greenhouse or conservatory, Pelargoniums for example can overwinter indoors to go out next year. Autumn planting of trees and shrubs is less stressful for them so preparation in October for November planting is a good move.
