SPRING
Once roses are well established, water them occasionally. Spray every two to three weeks as required, for the utmost performance. Check which sprays you can apply together, or need to be
separate. Spray in the cooler part of the day. Spray up and down the plant. You can use liquid fertilizers with your spray to give them a boost. Many older varieties need more attention.
Most of the newer varieties released in recent years (last 10 years) are more disease tolerant, and some people elect for a spray free policy. Feed roses again mid to late November.
SUMMER
To promote a second and third flush of flowers, dead head the spent flowers over summer. Prune back by about 20cm. Feed roses again in February for their final autumn flush. Water occasionally over summer. If roses are potted, water regularly, and have a saucer under your pot.
For a special event, or to time a flush of flowering, cut back the roses 8 - 9 weeks prior to the required date. Fertilize and water well into the ground, avoid overhead sprinklers.
Be careful spraying your lawn for weeds near your roses. Avoid using Roundup near your roses, use Buster.
Roses are very forgiving and will grow and flower with as much or little care you wish to give them. Enjoy!
