VEGETABLES

 

FLOWERS

Sow leaf lettuce such as Salad Bowl 12mm (1/2 inch) deep in rows 25-30cm (10-12 inch) apart.

 

Provide stakes for delphiniums, hollyhocks, pinks and any other tall or weak-stemmed perennials.

Sow leeks in a seedbed, 12mm       

(½ inch) deep

Prune forsythia when it has finished flowering.

Thin summer lettuce to 23-30cm      (9-12 inches) apart.

 

Plant out bulbs which have flowered indoors.

Harvest spring cabbage cutting them off at soil level.

 

Plant late flowering perennials, gladioli and pinks.

Sow winter cabbage for harvesting from early November to Spring. Sow seeds 18mm (¾inch deep) in drills 15cm (6 inch) apart in a seed bed.

 

Water newly planted roses thoroughly during periods of dry weather apply a mulch to help them retain moisture.

Thin carrots to5cm (2 inch) apart.

 

If not already done, feed and mulch established roses.

Sow garden peas. Make a flat bottomed drill approx. 15cm (6 inch) wide and 7.5cm (3 inch) deep and sow the seeds in 3 rows, 5cm (2 inch) apart each way. The space between rows should be about the height of the crop.

 

There is still time to lift and divide large clumps of herbaceous plants. Replant the young healthy parts from around the outside and discard the old woody middle.

Sow beetroot seeds early in the month 10cm (4 inch) apart in rows 17.5cm    (7 inch) apart. The plants are thinned to one per station.

 

Delphiniums, herbaceous phlox and lupins can be increased from root cuttings.

Thin onion seedlings 5-7.5cm              (2-3inch) apart.

 

Plant water-lilies and other water plants.

Thin summer spinach to 7.5cm         (3 inch) apart, then later to 15cm (6inch) apart.

 

Continue to remove the faded flower heads from bulbs.

Sow second early and maincrop potatoes, 15cm deep (6 inch) and 38cm (15 inch) apart in rows 70cm (28 inch) apart.

 

Hoe between plants to keep the weeds down.

FRUIT

 

LAWNS

Apply sulphate of potash to the soil around gooseberry bushes, 25 grams a square metre (¾ oz per square yard)

 

Sites for new lawns can be prepared now if the soil is not too wet.

l Dig, weed, rake and level, removing all stones above 5cm (2 inch) diameter. Soil preparation can be completed by treading the soil, shuffling sideways across the plot. Do not use a roller.

l Rake the surface level, then rake a lawn fertilizer into the top 2.5cm     (1 inch) of soil

l Sow a suitable seed mixture evenly, a week after adding the fertilizer.

l Lawn seed will germinate between 7-10 days from sowing. Stretch black cotton over the site to deter birds attracted to the seed.

l Carefully water site in dry weather.

Prune plums and gages as soon as the sap starts rising.

 

Prune peaches and nectarines as soon as the buds start to develop.

 

Apply sulphate of ammonia around blackberry and hybrid berry plants at the rate of 70 grams a square metre (2oz a square yard)

 

Shallow hoe around raspberry canes to avoid damaging the roots. Feed with 25 grams a square metre (¾ oz per square yard) of sulphate of potash.

 

Feed established lawns with a quick acting lawn fertilizer at 70 grams a square metre (2oz a square yard).

Spray against pests and diseases at bud burst or after petal fall, but never on open flowers. Avoid using these sprays when pollinating insects are active.

 

Continue mowing established and new lawns in dry weather, gradually lowering the mower blades.

GREENHOUSE

 

GENERAL

Plant greenhouse tomato plants into large pots or growing bags. Sow tomatoes for planting out later in the year.

 

Avoid using sprays when pollinating insects are active.

Harden off bedding plants sown under glass and previously pricked off into boxes. Protect from frost in a cold frame or in the shelter of a south-facing wall.

 

Hazel and birch twigs make good natural pea sticks and supports for perennial plants.

Sow melons and cucumbers for growing in the greenhouse. Sow two seeds in each pot at a temperature of 18oC/64oF, thin to the strongest seedling.

 

Check the supports of climbing plants and make repairs to structures and supports before the onset of vigorous plant growth.

Hanging baskets can be planted up later in the month. Hang up, or place on the top of a large pot. Keep well watered until they can be safely placed outside when the danger of frost has passed.

 

Protect fruit against bird damage with netting or fruit cages. Inspect the netting and structure now for damage and holes and repair it where needed.

Continue to prick out crowded seedlings into pots or boxes.

 

Always use a RDC (residual current device) circuit breaker when using electrical garden equipment.
