Rose Care Calendar

Summer

Maintain moisture levels by a weekly deep soak.

The once flowering roses can be pruned back following their flowering display in late November / December.
Spider mite can be an issue in hot dry weather. Spraying with water underneath the foliage will discourage the spider mites. Two sprays with a miticide a fortnight apart should control severe outbreaks.

Fungal problems are usually not a problem during South Australia’s summer season unless on the rare occasions there is extended rainfall.

Now is the time to plan the rose bed. Select a site that receives six hours of sunlight each day. When replacing poor performing roses remove the old rose and as much of the roots as possible and incorporate organic material, Neutrog’s Seamungus and GoGo Juice into the area.

In late summer a full deadheading program will ensure plenty of blooms for the Autumn Rose Show. As a guide, trim your roses fifty days before the rose show or an autumn wedding for a magnificent display. Apply Sudden Impact for Roses around this time.

Autumn

Keep your rose bushes in tip top condition with preventative sprays of Triforine, Mancozeb Plus, Pest Oil or eco oil. Fungal problems usually occur when there is moisture on the leaves for more than six hours.

Fertilize in early autumn with Sudden Impact for Roses if there was no application in February.

Autumn is the ideal time for roses and the production of quality blooms. Remember the fifty-day rule for rose trimming before an event where you need the rose garden to be at its best.  Continual deadheading throughout autumn will ensure the display until cold winter weather sends the rose into dormancy.

Order your mail order roses and continue your soil preparation for the new roses.

Winter

Winter is the best time to prune your roses. Remove dead, non-productive canes and spindly growth. Remove suckers, ensuring that water shoots are left. Cut back remaining canes by around a third, remembering that harder pruning produce fewer but better quality blooms while more blooms are the result of a light prune. Clean up around the base of the plant and spray with lime sulphur or an oil-based spray.

Bare rooted roses are planted out in late winter. Upon arrival place the bare roots in a bucket of water for one or up to twelve hours to allow hydration of the roses. Dig your hole and spread the roots over a slight mound at the bottom of the hole. Back fill and ensure the bud union is level or slightly above the surface of the rose bed. Water well and maintain soil moisture as the rose develops. No fertilizer is applied at this stage, but a soil conditioner such as Neutrog Seamungus is highly recommended and can be added to the base of the planting hole. Label your roses and make a planting plan.

Recommended plant spacing 1.3 to 1.5metres for hybrid tea and shrub roses, 1metre for floribundas, patio and ground covers.  A half metre is usually sufficient for miniature roses.

Winter is the recommended time to shift roses when they are dormant. Prune the rose before transplanting. Apply Neutrog Seamungus for healthy plant development

Mulch around your roses in late winter to avoid damage to new growth if mulching is left until spring.

Spring

Fertilize with Sudden Impact for Roses when growth first appears.

Ensure you have mulched around your roses.

Stake new water shoots.

Keep black spot and mildew at bay by protective spraying with Triforine or Mancozeb Plus. Pest or eco oil will quickly control any scale problems.

Avoid spraying insecticides to eliminate aphids, as the beneficial insects will quickly control these pests. Squirting a jet of water will help keep them under control until the beneficials take over.

Enjoy the pleasure of roses in the home by cutting the blooms early morning or evening and placing in a bucket of water.
