Garden Jobs for August
1. Prevent Peach Curly Leaf – Spraying to prevent peach leaf Curl disease is essential if you are growing fruiting Peaches, Nectarines or Ornamental Peaches. Spray trees thoroughly with Yates Liquid Copper or Fungus Fighter. If you have time spray once now and again at the early bud swell time.
2. Rose Pruning – Don’t panic! Theres’s still time to prune your roses. Don’t be afraid to have a go. Pruning is always an invigorating process for roses. Hybrid tea roses, miniatures and floribunda roses can simply be cut back to half their original height, using secateurs, loppers or hedge shears. Aim to have pruning finished by mid-late August.
3. Protect Plants From Snail And Slug Attack – After good recent rains, snails and slugs are having a field day. So it’s essential to protect new seedling plantings. The best defense is a light sprinkle of a quality snail bait like Multiguard Snail & Slug Killer.
4. Spray Grapes To Protect Against Blister Mite – Spray dormant grape vines with Lime Sulphur to protect against grape vine blister mite. It’s a good insurance policy to protect your vines. Grape blister mite becomes evident later in the season when ugly, raised pimple like blemishes start to appear on the leaves. Below each pimple is a mealy looking, colony of blister mites.
5. Plant Asparagus Crowns – Be quick for our WA sourced Asparagus Crowns. Asparagus crowns should be planted as soon as possible after purchase. Prior to planting improve the soil by blending in plenty of Dawson’s Soil Improver to at least a spades depth. Add a sprinkle of Dawson’s All Purpose Fertiliser or Eco Prime Garden. Dig a trench 30-40cm deep and 30cm wide, then lay a 10-15cm layer of Dawson’s soil Improver and Cover this layer with a 5-10cm layer of improved soil. Then make a mound of soil along the centre of the trench. Crowns are planted top of the mound with roots spread out either side (the crowns should be placed so that they are about 10cm below the surface soil). Cover the crowns with about 5cm of soil, then gradually fill to soil level as the plant grows. Dawson’s also supplies potted Asparagus plant year round.
