FOR MORE GREAT IDEAS: www.dawsonsgardenworld.com.au PLANTING ROSES Because Dawson’s roses are grown in pots, you can confidently plant them into your garden at any time of the year. 1) Before planting, water the rose in its pot. 2) In a sunny location, dig a hole 60cm wide and 45-60cm deep. Mix Dawson’s Garden World Organic Soil Improver with the soil from the hole at a rate of 1 part Soil Improver and 2 parts soil from the hole. 3) Return enough of this mix to the hole to achieve the correct height for the new plant. 4) Take the rose out of its pot, leaving the root ball intact and place in hole. Add 1 tablespoon of slow release fertiliser around the rootball. 5) Return more of the mix around the plant until the soil is level, then add mulch, leaving a 15cm clearance around the stem. 6) Water in well (use at least 10 litres of water per plant), ensuring the root zone is thoroughly saturated 7) Liquid feed fortnightly with Seasol to help stimulate root growth and get plants off to a flying start! WATERING • Water newly planted roses daily during their first season in the garden. • Soil wetting agents allow water to penetrate into water repellent, sandy soils. Apply in spring and midsummer. For a more permanent fix, try mineral claybased soil builders like Soil Solver. • Established roses that have been in the garden more than a year will survive happily on two good soaks a week. • Remember roses growing in pots dry-out much quicker than roses in the ground, so water daily during the growing season for best results. STAKING • Standards and weeping standards will require a permanent and strong stake for support. FEEDING • Feed roses at regular 4-week intervals from spring to late Aprilearly May. • A fortnightly liquid feed, with a combination of Seasol and Powerfeed, is a great addition to your rose feeding program. MULCHING • Use coarse grade mulch applied to the soil at a depth of 5-10cm, leaving a 15cm bare circle around the main stem. Never heap mulch or soil up around the stem. ROOTSTOCK We use Rosa Fortuniana rootstock which is proven to outperform all others in WA conditions with its vigour and hardiness. COMMON DISEASES & PESTS • Black Spot and Powdery Mildew are common rose and fungal diseases. They are most prevalent in early-mid spring and again in mid-late autumn when nights are often cool and damp. Diseases are also more likely on roses growing in too much shade. To Control Black Spot and Powdery Mildew spray with rose fungicides such as Eco Fungicide (used in conjunction with Eco Oil), Rose Shield, Triforine or Sharp Shooter Rose Black Spot and Pyrethrum Concentrate. Better still is preventative spraying, every fortnight over mid- spring and again in mid-late autumn. • Avoid overhead watering. • Control aphids and thrips with systemic insecticide, used monthly. • Red spider mites are the most troublesome pests of roses over the warmer months. Spray with Mavrik*, Natrasoap*, Eco Neem* or Eco-Oil*. Spray twice, two weeks apart, to bring mite populations under control. Predatory mites can also be ordered from your nearest Dawson’s store. • White Rose Scale - Spray with Eco- Oil* or White Oil*. Severely infested canes should be pruned out at pruning time. • Herbicide Damage – Don’t use Glyphosate herbicides near your roses. CHILLI THRIP CONTROL • Cut off all affected growth including flower buds and open flowers. • Spray every 7-10 days with either Success, Conguard or Mavrick. • Ensure the entire plant and underside of the leaves are well soaked in the spray mixture, including the soil around the rose bushes. It is also important to follow up with 2-3 sprays to keep the Chilli Thrip under control. • Monitor your rose bushes by checking the new growth. If Chilli Thrip are present, you will need to continue to spray. * During the warmer months, don’t spray during the heat of the day, or when temperatures exceed 35°C. PRUNING THE EASY WAY The object of pruning is to shape the bush and promote new blooms. Pruning is done every year in winter while plants are dormant, before new spring growth appears. • Before starting, make sure pruning tools are clean and sharp. • Hybrid tea roses, miniatures and floribunda roses can simply be cut back to half of their original height, using secateurs, loppers or even hedge shears. • Tidy up by removing any crossing branches, diseased older wood or branches growing into the centre of the bush. • David Austin rose bushes are best pruned by removing one third of their original height each winter. • Climbing roses should be pruned and trained to restrict them from growing straight up. This is best done by tying new canes to a horizontal position or by arching into a fan shape. • Immediately after winter pruning, thoroughly spray bushes with Lime Sulphur. • Need more help?
