Get into Dawson’s and beat the winter chill!

It’s July and winter is really here. Chilly mornings give way to glorious, sunny days. Make the most of sunny weather to enjoy the garden, complete major plantings and get the secateurs ready, it’s pruning time!

Winter Rose Pruning

Give your roses the snip! Rose pruning is really the kindest cut of all. It’s always an invigorating process for roses and you’ll be delighted with the spring flush of blooms. In Perth and generally frost-free districts, roses can be pruned any time from mid-June until mid-August, while in cooler frost prone districts pruning can be left until late July and August.

FREE! Rose Pruning Demonstrations at Dawson’s Forrestfield, Joondalup, Swanbourne and O’Connor. All sessions start at 11am on the following days: Saturday 12th July

Rose pruning is actually very easy. Why not come and watch one of our free rose pruning demonstrations? These popular, practical sessions are presented by Dawson’s staff and cover all aspects of rose pruning and winter rose care. Come along and join in! A free Dawson’s Rose Pruning Made Easy leaflet is also available from all stores.

Garden Jobs for July

1. Rose Pruning – Hybrid tea roses, miniatures and floribunda roses can simply be cut back to half their original height, using secateurs, loppers or hedge shears. Follow up by removing and dead, diseased or crossing branches and any branches growing directly into the centre of the bush. Immediately after pruning, thoroughly spray canes with Lime Sulphur.

2. Prune Grapes – Can be pruned now. There are two main styles of grape pruning spur and cane pruning. The majority of grapes can be spur pruned. To establish a spur system simply cut back a number of the most vigorous canes growing off the main framework arms (branches) to just two buds length. In spring each of these buds produces a cane, which will bear a number of fruit bunches. Ideally spurs should be spaced 15-20cm apart along the main arms. The following winter cut each spur back to the best and lowest cane and then cut this back to two buds length to maintain the spur. Some varieties of grape such as Sultana are not fruitful when spur pruned so they are cane pruned. To cane prune select a number of the strongest canes arising from the main arms (branches) and prune these back to canes of 8-15 buds in length. Then twist or tie these onto support wires. Follow pruning with a dormant spray of Lime Sulphur to prevent Grape Blister Mite.

3. Protect Plants From Caterpillar Attack – Caterpillars particularly white cabbage moth and tiger moth larvae (also known as “woolly bears”) are very active at this time of year. These are voracious eaters and can be very destructive to most soft foliaged plants. To control, begin spraying with Yates Success as soon as damage is noticed and repeat spray at 7-14 day intervals while pests are active.

4. Protect Plants From Snail And Slug Attack – Snails and slugs become more active following the first rains. These pests can be particularly devastating to new seedling planting so beware. The best defence is a light sprinkle of a quality snail bait like Multiguard Snail & Slug Killer.

5. Transplant Trees And Shrubs – July is a good month for transplanting as plants won’t be heat stressed at this time of the year and it’s easier to maintain soil moisture while they settle in. The key with all transplanting is to try to retain as much of the original root system as possible. Prune plants to compensate for the root loss during transplanting. Plant into soil improved with the addition of Dawson’s Soil Improver and keep transplants well watered until established.

July Planting Guide

1. Double Grafted Cherry Minnie Royal/ Royal Lee – These multi grafted Cherry trees are grafted with a cross pollinating pair of low chill varieties, Minnie Royal and Royal Lee. These varieties were developed in America for growing in warm temperate and mild winter climates. They have estimated winter chill requirements of only *200-300 hours, so they are well suited to growing in Perth. Minnie Royal has rounded juicy, red fruit and Royal Lee has rounded to heart shaped fruit. Both varieties have red to dark red skin with red flesh and mature in early December. (* Chill hours refers to the cumulative number of hours below 7 ºC recorded over a winter period)

2. Spicezee – We think Spicezee is one of the most exciting new fruit trees we’ve seen in recent years. Spicezee is a nectarine/plum cross. It has maroon-red skinned fruit with pale green-white, juicy flesh with a distinctive tang. The fruit matures mid-January and is freestone. The tree has purplish-pink spring time blossom, followed by attractive red hued spring foliage which gradually fades off to green over summer. Spicezee is a vigorous tree to 4m high and wide.

3. Crimson Rocket- The first columnar Peach to be released in Australia. A unique variety with a naturally narrow and upright growth habit. Produces medium sized, yellow fleshed, freestone, juicy, sweet fruit. Just perfect for desert! Ideal for growing in pots or narrow spots.

4. Black English Mulberry – What childhood would be complete without climbing a backyard Mulberry Tree and feasting on its delicious fruit. The Black English Mulberry is an old favourite with delicious red/black juicy fruit, maturing in late spring. Attractive rounded to slightly heart shaped foliage. A slow growing tree, gradually forming a dense, rounded canopy, giving good shade. Grows to around 4m high and wide. We also have available Mulberry Hick’s Fancy, a much faster and taller growing Mulberry, also maturing in late spring.

5. Prunus Oakville Crimson Spire – This narrow growing, spire like ornamental Plum, is one of our best-selling trees and deservedly so! Crimson Spire is perfect for modern smaller gardens and very useful for providing a tall privacy screen. Growing to only 1.5m wide and 6m high at maturity, it’s a great one for planting along the fence. Crimson Spire has white to palest pink blossom in spring and burgundy/purple blushed foliage.

Standard Rose Iceberg

Iceberg

We now have new seasons stock of Standard Icebergs available, along with many other standard roses! As a standard rose, Iceberg is just as reliable and prolific as the bush Iceberg. It carries great flushes of semi-double, white blooms throughout the season and often well into winter! It is very rewarding with endless uses; plant in feature pots, plant either side of an entrance or along the drive way, or use to add interest to rose and flower beds. While it is most happy in full sun situations, Iceberg performs admirably in semi shade also.

Iceberg is one of the world’s most popular roses, bred in Germany by Reimer Kordes and released in 1958.
