Garden Problems, Pests & Diseases

Insects:
  • Asparagus beetles: Watch out for and can be removed by hand. 
  • Flea beetles:  Cause problems on brassica plants, but you can keep a look out for typical small holes that they make and ensure additional watering to help them grow well despite the damage.
  • Carrot Fly: If growing at ground level protect with insect proof mesh / netting.
  • Apple Sawfly: Treat to prevent damage fruit blossom (Blossom Wilt), usually only necessary if it happened the previous year.
  • Capsid BugTreat to prevent damage fruit blossom (Blossom Wilt), usually only necessary if it happened the previous year.
  • Codling Moths:  Add traps to apple trees

Pigeons: Brassicas and Peas are a particular favourite at this time of year, so given them some projection from pigeons.

Slugs: Continue to manage and treat to prevent any damage to crops
Mould:  Remove yellowing leaves from brassicas to reduce spread of Grey Mould and Brassica Downy Mildew (it also reduces habitat for slugs and snails)

Diseases:
  • Spur Blight: Look out for and treat on Raspberries, Blackberries and other fruit shrubs.
  • Cane Spot:  Look out for and treat on Raspberries, Blackberries and other fruit shrubs.
Birds: Protect soft fruit with bird netting, but make sure small birds can not become trapped inside. and check regularly
Raspberries:  Leaf and Bud Mite, as well as rust may start to become a problem 

Weeds: Ensure weeds are kept down and keep this up throughout the summer. 

General care

Vegetables

Potatoes: Start earthing up as the plant grows (around 20-25cm tall, leaving only 5cm above the soil to allow continued growth.  This prevents new potatoes greening in sunlight.

Tomatoes:  Remove side shoots on cordon tomatoes as soon as you see them.  These can be found in the angle between the stem and leaves, usually at 45 degrees.  They will take away energy that could be used to grow the fruit and reduce yields

Broad Beans: Stretch string along the top of plants to provide support and stop them collapsing under the weight of developing pods.

Peas: They will need supporting with pea sticks, netting, or twigs that have been taken from the garden.

Fruit

Fruit Trees: Remove suckers that grow from the base of the tree

Liquid Feed: Fruit trees grown in pts will benefit from a feed every couple of weeks.

Strawberry Plants: Remove flowers on new runners planted after September.

Watering:  Ideally use rainwater to water Blueberries, Cranberries and Lingonberries.

Melons:  If you are growing melons, now is the time to warm up their grow bags, simply by putting them in the green house.  Ensure they are well watered prior to planting.

Grapes: Indoor vines will need to be hand pollinated, simply by running hands over the flowers

Water Well:  Especially those in pots and plants against walls are at risk from drought stress even if there has been some rain.

Pollination:  Ensure bees and other pollinating insects can access fruit flowers that are usually caged or covered.

Blossom: Protect from frosts if neccesary
