There may be slugs when its wet, greenfly when its dry and spiders and caterpillars when it is hot. Tackle problems as soon as they arrive.
There are two ways to tackle pests in the garden, culturally and chemically. Prepare the ground well, this will make sure plants grow well and are healthy. Try to keep the ground free from soil pests.
Ants will loosen the soil around plants so that they wilt and die. Woodlice hide under decaying leaves and plant pots, they come out at night to attack seedlings and young plants.
Slugs and Snails are serious garden pests, particularly when the weather is wet and cool. They hide under stones during the day and come out at night and devour seedlings, roots, stems, leaves, flowers and mature plants.
Cutworm eat plants at ground level they are very busy during late summer. Grubs feed throughout the year on roots of trees, shrubs, flowers and vegetables, Millipedes damage seedlings and underground parts of mature plants.
By digging, liming and rotating crops you will be able to keep down the number of pests in your garden. For Worms and Grubs, use Bromphos or an equivalent, for Millipedes apply BHC dust to the soil and rake lightly.
For Slugs and Snails use snail bait, spread around the base of plants and scatter around seedlings and for Ants sprinkle anti-ant powder along ant runs. Insect contact control is used for sap sucking insects such as greenfly, and works by hitting and killing the pests.
Spray during attacks, use a forceful jet and cover all the plant. Leaf contact is for plant chewing insects such as caterpillars, it works by coating the insects source of food.
Systematic insecticides work by going inside the plants and into the sap stream. This means that new growth after the attack is protected.
Some problems you may encounter are mildew, canker, greenfly, silver leaf, woolly aphid, leaf curl, capsid, brown rot, scab, moths and caterpillars. Benlate will work for Greenfly, caterpillars, capsid, weevils, scab and mildew.
For Brown rot, make sure you burn the diseased fruit and leaves. The best solution is to spray with Dursban twice a month from May until October. This is a very good general insecticide and should be used on lawn, shrubs, trees and flowering plants.
It is worthwhile investing in a good pump action spray, preferably one that straps onto your back, although if you have a small terrace garden or container garden, the hand held sprays are adequate.
Dont forget the importance of feeding plants, flowers and vegetables love bone meal, spread around the base of plants. Roses love to be fed with a rose fertilizer and a liquid feed around the base, and laws need a fertilizer with high nitrogen content. If you inspect the plants in your garden regularly you will know exactly when you have little troublesome invaders.
