General tips
- Installing a 2 - 3 foot high wire mesh fence
with 1 inch or less opening will exclude rabbits from the garden.
Secure the fence to the ground with "sod staples" so
they cannot get underneath it..
- Keep your eyes open for pests and diseases
in the greenhouse and the garden, and take appropriate action
immediately to stop the problem getting out of hand.
- Weed regularly.
- If the weather is dry be prepared to water
vulnerable plants.
- Ventilate the greenhouse and apply shade
paint if necessary. Damp down if the weather is hot
- Use contact weedkiller to control rampant
weeds; its not too late to mulch.
- Use fungicide on plants prone to mildew in
dry weather.

Lawns
- Progressively lower the mower blade.
- Trim your lawn at least once a week
to keep it neat and dense.
- Trim lawn edges each time you mow.
- Treat weeds individually with a spot weeder
or dig them out with an old knife.
- Remove any coarse grasses by hand.

Containers
- It is essential to keep all container plants
well watered
- Tidy summer containers. Remove fading flowers
regularly.
- Feed container-grown shrubs and perennials

Annuals
and biennials
- Support tall-growing hardy annuals.
- Now is also a good time to cut back leggy
annuals and perennials like petunias, cornflower, black-eyed susan,
spiderwort and yarrow. Removing dead flowers will stimulate repeat
blooming later this summer.
- Spider mites love hot dry weather and are
very active currently on many plants. They feed on the underside
of leaves and can been seen with an unaided eye. Spider mite damage
is called stippling and looks like tiny yellow dots on the leaves,
in severe infestations the entire leaf may look yellow. Control
them with by spraying the plants daily with a hose or apply insecticidal
soap.
- Thrips feed on flower buds and opened flowers
which causes them to turn brown. Check the underside of leaves
for their presence, it will look dirty and silvery. Control with
insecticide.
- Attract beneficial insects that will help
to naturally control pest insects to your landscape and gardens
by planting a wide variety of flowering annuals and perennials
that bloom over the entire growing season. We suggest marigolds,
daises, asters, mums, carrot, dill, fennel, parsley, mint, and
thyme.
|
Perennials
- Put plant supports and stakes in position.
- Remove weak new shoots.
Roses
- Spray bush and climbing roses with fungicide
and insecticide mix.
- Dead head regularly to encourage flowering.

Shrubs, Trees and Climbers
Herbs
- ·Pinching back herbs to stop flowering
will keep the best flavour in the leaves and encourage branching.
Fruit
- Harvest blackberries when the fruit is a
dull, deep purple, then prune the fruiting wood away.
- Raspberries in intense sunlight that also
experience high temperature can show symptoms of White Druplet
Disorder. The fruit becomes hard and turns white, but is still
edible.
- Thin tree fruit clusters.
- Tip-layer bramble bushes to get new plants.
- Old strawberry beds (3-4 years) should be
renovated this month. Peg down any runners into pots if you want
plants for forcing.
- Brown rot affects peach, cherry and plum
fruit. Small brown spots develop in bruised or punctured fruit
skin usually one to three weeks before harvest. The fungal lesions
expand and the fruit turn brown, shrivel and are then referred
to as "mummies". Control disease with early and continued
fungicide applications, by removing mummies from trees and ground,
and with proper annual pruning in February.
- Harvest fruit gently being careful
not to bruise the skin.

Vegetables
- Lift shallots and dry for storage.
- Transplant winter cabbages and brussels sprouts.
- Sow chicory and radiccio for winter forcing.
- Sow swiss chard for winter leaves.
- Sow late carrots and turnips, using 'early'
varieties.
- Lift last of the early and second early potatoes.
- Earth up maincrop potatoes for the last time.
- Sow fast-growing lettuces such as little
gem for a late crop.
- Ensure pumpkins and marrows are supported
off the soil on bricks or tiles.
- Flea beetle is a serious pest of brassicas.
This small black beetle is named for its habit of jumping when
disturbed. Damage symptoms are small shot holes in leaves. Good
botanical insecticides are used to control them.
- Some things are easy to grow and take minimal
effort. Spinach, swiss chard, flat-leafed parsley, kale, beans,
rocket, potatoes and courgettes are all great beginners' plants.

Greenhouse
-
Remove tomato plant leaves
infected with the Early Blight fungus. Look for leaves with
lesions resembling a bulls-eye pattern and yellow halo on the
lower part of tomato plants. The fungal spores splash up from
soil onto the lower leaves, but are also spread on wind currents.
Prevent disease by covering the soil with newspaper and watering
only the base on the plants. Apply a copper fungicide to severe
disease outbreaks.
-
Cucumber plants that continue
to wilt despite watering are infected with bacterial wilt disease
transmitted by the cucumber beetle. The is no control for the
disease, remove infected plants.
