VEGETABLES

FLOWERS

Prior to sowing seeds, fork over vegetable beds, remove weeds, rake to fine tilth and apply a general fertilizer.

 

Cover dahlia tubers with moist compost and keep in a warm humid place. Growth will appear in about 3 weeks.

Plant out leeks sown under glass in January.

 

Snowdrops can now be planted ‘in the green’ after they have finished flowering.

Sow parsnips for autumn cropping.

 

Plant out autumn raised sweet peas.

Sow cauliflowers and Brussels sprouts in a seed bed for planting out in June.

 

Top-dress establishes borders with a general fertilizer.

Sow broad beans 10cm (4 inch) apart in drills 75mm (3 inches) deep and 25cm (10 inch) apart.

Plant out hardy perennials as soon as the ground is ready.

Sow carrots thinly in drills 12 mm (½ deep) and 20cm (8 inch) apart.

 

Sow hardy annuals where they are to flower.

Sow radishes 12mm (½ inch) deep in rows 15cm (6 inch) apart.

 

Lift and divide large clumps of herbaceous plants. Replant the young healthy parts from around the outside and discard the old woody middle.

Sow summer spinach 12mm (½ inch) deep in rows 30cm (1ft) apart.

 

Complete the planting of container and bare rooted bush and climbing roses as soon as possible.

Protect early sown vegetables against frost with fleece.

 

This is the last chance to prune established bush and climbing roses. If late frosts damage new shoots prune back to an undamaged bud.

Plant early potatoes 15cm deep (6inch) and 30cm (1ft) apart in rows 60cm (2ft) apart.

 

Dead head bulbs as they finish flowering.

Remove straw covering globe artichokes and top-dress with a general fertilizer.

FRUIT

LAWNS

Winter prune gooseberries. Cut out damaged and low growing shoots. Cut back the shoots on newly planted bushes by half.

 

Cut edges of lawns/flowerbeds straight with a half-moon edger. Lawn edge grass can be trimmed with edging shears.

Spray blackcurrants against big-bud mite.

 

Sow new lawns if the weather is warm.

Spray apple and pear trees against scab disease.

 

Remove any leaves from lawn with a stiff brush or wire lawn rake.

Blackcurrants, raspberries and strawberries can still be planted. Hard prune blackcurrants and raspberries after planting.

 

Brush and scatter worm casts to prevent unsightly patches. Flattened worm casts can suffocate fine grasses.

Train blackberries and loganberries onto support wires.

 

If the grass is long do not cut it too closely, set the mower blades high and gradually reducing the blade height over time.

Protect the opening flowers of peach, almond and apricot from frost with netting or fleece.

 

Patchy areas of lawn can be overseeded now or in the autumn. Net newly seeded areas to protect from birds.

GREENHOUSE

GENERAL

Sow chillies and peppers now for harvesting from mid-July onwards. Sow in 3cm (1¼ inch) compost  plugs. Provide bottom heat of 20ºC (68ºF) and keep well watered.

 

Before putting tools back in your shed apply oil or DW40 to prevent rust. Keep an oily rag handy to wipe the cutting edge after use.

Check all plants for pests and diseases and treat by spraying or fumigating as necessary.

 

All garden machinery should be serviced. Safety checks should be carried out and worn and damaged parts replaced.

Move forced bulbs as they finish flowering to a sheltered cool position. Stop watering and allow the foliage to die back naturally

 

Remove algae from ponds using a net or rake.

Re-pot all plants that have filled their pots with roots.

 

Continue hoe between plants to remove emerging weeds.

Ventilate the greenhouse whenever necessary, avoiding draughts..

 

Replenish stone chippings or gravel in the rock garden.
