Ready To Make Your ROSE GARDEN The Envy Of Neighbours?
Rust
Rust is a disease that creates an orange powder in the center of the rose. It is caused by wet and calm winter weather. Putting in some spider mites can help with this because they hate the water. You should consult your local garden center about the best insecticide to use in order to get rid of the spider mites. Once you have chosen the insecticide, spray every 7-10 days until it is under control.
Steps:
Look for rust on the undersides of the foliage. It resembles patches
of rust-colored velvet.
Rake up and dispose of all fallen leaves and debris from under the
plant. Rust spores are carried by water splashing back up onto the
stems and leaves. (Removing the source of the problem should always
be your first step.)
Water roses at the base of the plant instead of overhead.
Water in the early morning hours to give the plants time to dry
out during the daylight hours.
Provide air circulation by pruning and thinning the plant.
Avoid planting annuals or other type plants under roses; this will
provide maximum air circulation.
Remove and destroy infested foliage.
Dust plants with sulfur powder every one to two weeks, starting
when foliage begins to develop in the early spring and continuing throughout
the growing season. The sulfur won't kill the rust, but it will prevent
the next generation from germinating.
Spray with a solution of 1 tsp. baking soda in 1 qt. water to fight
rust.
Spray roses with a dormant oil or Bordeaux mixture when plants are
dormant (usually in winter).
Tips:
Rust is more unsightly than terminal for most rose plants.
Rust is very difficult to eliminate once it appears.
Prevention is the best form of defense.
Spray organic fungicides early in the day for best results.
Chemical fungicides are available for the control of
rust. Always use the least toxic method of pest control first.
Warnings:
If you choose to use a chemical fungicide, always wear protective
clothing and safety gear, including a long-sleeved shirt, long pants,
neoprene gloves, goggles and a respirator.
