The nights are squeezing the light of day, despite sunshine there’s a chill in the air, and mornings are often shrouded in mist and fog. October marks the real onset of autumn, I think – here are a few important things to do in the garden this month.
1. Leaf litter pick
Clear up fallen autumn leaves regularly, including rose leaves, to prevent diseases such as black spot from over-wintering – don’t compost these leaves. Create compost bins for collecting fallen leaves and dead plant material or a separate ‘Leaf mould’ bin if you want to create this wonderful material – stuffing leaves in black plastic bags is another option.

2. Cut backs
Cut down stalks of perennials that have died down, unless they have some winter or wildlife merit. Clear overhanging plants away from pathways and prune climbing roses and rambling roses once they’ve finished flowering, tying in the stems before autumn winds cause damage.
3. Parting is such sweet sorrow
Divide herbaceous perennials and rhubarb crowns. This is also the time to move trees and shrubs, and plant hedges.

4. Come in out of the cold
Move tender plants, including aquatic ones, into the greenhouse or other frost-free place. Lift Dahlias and Begonia tubers and Gladiolus corms to store in the dry (removing the dead leaves before storing them). Cannas, Pelargoniums/Geraniums and fuchsias can also be lifted before any proper frost. Trim back soft growth on geraniums and fuchsias, potting them into multi-purpose compost and keeping them barely moist over the winter in a cool frost-free place.
5. Food – strip, store and plant
Strip: Apples, pears, grapes and nuts can all be harvested as can squashes and pumpkins before the first frosts. Finish harvesting beans and peas and once finished cut the plant away at ground level, leaving the roots in the soil as these have nodules on them that have fixed nitrogen from the air and will slowly release this as the roots break down. Any plants with green tomatoes or peppers remaining can be hung upside down indoors to ripen.
Store: Check over any stored onions, garlic and potatoes and remove any rotten ones immediately. Try to improve air flow around your stored veg to prevent rot e.g use onion bags or hessian sacks.
Plant: spring cabbages, garlic bulbs and onion sets. Reuse old grow bags by cutting off the top and sowing late salad crops – cropping can be extended into winter if grown under glass or a cloche. Autumn is an ideal time to plant bare root fruit trees – alternatively order fruit trees now in preparation for spring planting.
Careful storage of apples will give you a supply well into winter
6. Sourcing seeds
Collect seed heads from perennials, alpines, trees and shrubs. Order seeds for next year.

7. Spring loaded
Plant spring bedding such as wallflowers, Bellis, Primulas and winter pansies. Now is the ideal time to plant Clematis. Finish planting spring bulbs such as Narcissi and Crocuses – Tulips can wait until November.

8 Grassy act
Finish off essential lawn maintenance to avoid water logging and compaction over winter (see September tips for more detail). Fresh turf can still be laid now – Autumn rains (assuming we have some) should ensure the turf settles in.
9. Odds and …..
Remove netting from fruit cages to allow birds to feed on any pests and invest in bird baths and bird feeders if you don’t have them – the birds you support will help you keep pest numbers down. If you haven’t already done so, turf out the last of the tomatoes, cucumbers etc. from the Greenhouse and clean and disinfect it. This will allow more light in and prevent pests and diseases over-wintering. Set up your greenhouse heater if you have one in case of early frosts. Empty and if possible clean out water butts and let the autumn rains refill them. Maybe install a new water butt ready for next year? Check tree ties and loosen if they are too tight around growing stems – and add stakes and support for young trees and shrubs to avoid them being ‘wind rocked’ during the winter.

10. …Sods
Prepare your soil for next year – start digging in leaf mould, compost, manure and as much organic matter as you can lay your hands on to replace the goodness in it, though if your soil is on the sandy side, like mine, richer material like compost and manure is probably best left until the Spring when it’s nutrients are needed and they will not have leached away in the winter wet. However, if your soil is heavy, then pile it in now! It can be left in a pretty rough state over the winter when the elements will break the clods down, making spring planting that much easier.
