VEGETABLES

 

FLOWERS

Lift and store onions and main crop potatoes and carrots.

 

Lift and store gladioli corms.

Cut down asparagus to near ground level once the tops begin to yellow.

 

Buy and plant spring flowering bulbs such as daffodil and narcissi.

When harvesting beans and peas leave the roots in the ground as a natural fertiliser.

 

Dig up bedding plants once they have finished flowering.

Consider growing green manures. Sow whilst the soil is still warm and dig in once they have been killed by the frost. They help protect bare soil in the Autumn and some fix nutrients to reduce the need for fertiliser.

 

Divide perennials that have become overcrowded. Generally this will be every 3 to 5 years. First carefully lift them out of the soil and then divide with a fork for fibrous roots or a spade for fleshy roots and replant immediately.

Sow winter salads either in a warm, sunny part of the garden or in boxes. Protect from very cold temperatures.

 

Colchicums, autumn-flowering crocus, should be planted now in sunny but sheltered positions under trees.

Trim parsley to encourage fresh shoots.

 

Cut and dry seed heads for decoration indoors

Plant sets of overwintering onions from now until mid-October.

 

You can now plant shrubs, trees and other hardy plants.

Place cloches over outdoor tomatoes to help to ripen the last fruits. First cut the plants from their stakes and lay them along the row.

 

Herbaceous clematis, which flower on the current season’s growth, can be planted now for next year. Plant 2” deeper than they come in the pot to protect against clematis wilt and encourage basal buds.

Harvest haricot beans when the pods turn yellow.

 

Finish taking cuttings of tender perennials.

Plant spring cabbages 25 – 30cm apart (10 – 12in) in rows 30cm (12in) apart. Plant firmly to avoid wind rock or frost heave.

 

Take hardwood cuttings of roses using the current season’s growth, about the thickness of a pencil. They can be rooted out of doors or in a cold frame.

FRUIT

 

LAWNS

Pick pears as soon as they can be removed stalk intact.

 

Continue to mow the lawn, gradually raising the blade height

Continue to pick apples as soon as the stalks part easily from the spur. The stalks should remain attached to the fruit.

 

If you haven’t fertilised for six weeks consider another application but with an Autumn product

Plant peaches and nectarines. These are best grown as wall-trained trees and protected from cold winds.

 

Any patches in the lawn can be re-seeded now. Use an Autumn pre-seeding fertiliser and rake in some seed.

Dig up strawberry runners required for propagation and pot them up or transplant directly into new beds

 

To prevent the lawn becoming waterlogged spike or aerate it to improve drainage.

Space out the new raspberry canes formed during the year which will bear fruit the following season.

 

Remove moss and dead grass using an electric-powered lawn rake or a hand rake.

Plant blackberries and hybrid berries any time from now until late winter.

 

Lay turf for new lawns, water well and ensure it never dries out.

GREENHOUSE

 

GENERAL

Continue to maintain good ventilation to reduce condensation and the risk of mildew. Also reduce watering for the same reason.

 

Check supports and ties on young trees and climbers after early autumn gales.

 As the duration and intensity of daylight reduces, any shading put up for the peak summer months can be dismantled to allow more light into the greenhouse.

 

Try collecting your own seeds. Foxglove, honesty and sunflower are easy ones. Cut off a near mature seed head and hang in a paper bag to ripen.

Consider growing annual flower seeds to provide an early spring display

 

Winter hardy spring bedding plants can be planted now whilst the soil is still warm.

Pot up hyacinths and narcissi for flowering indoors at Christmas.

 

Summer-flowering wildflower meadows can be cut this month.

Pick all tomatoes and cucumbers and clear away the plants. Support canes should be cleaned and stored for next year.

 

Remove any rubbish left on the soil from crops to prevent pests and diseases lingering in the soil and spreading.
