SUMMER CARE OF ROSES GUIDELINES
1. Water! 2 to 3 times a week. More if it is hotter. Roses in
containers need even more water.
2. Fertilize! Every 3 to 4 weeks with liquid, granular or organic
fertilizers. Every 2 to 3 months with slow release fertilizers.
3. Mulch! Roses love organic soils. This also keeps the
temperature cooler for the roots and keeps the moisture level more even.
4. Dead-head the old flowers. Constant pruning of old flowers and
rose hips will trick the rose into producing more roses. It
is only necessary to remove the rose flower. If you want to prune
back harder, remember to
cut the flower stem back to a leaflet with 5 leaves.
5. Insects. Insects are usually more of a problem in cooler
weather, especially aphids. However, snails can always be a problem,
also earwigs and grasshoppers. Thrips are tiny and attack the flowers,
often distorting them or making the flowers not develop properly. Any
of the systemic insecticides, either sprayed on or granular, take care
of most pests. Often by the summer, beneficial insects have caught up
with pests and take care of most of them.
6. Diseases. Rust, mildew, blackspot: when it is hot and dry,
most these diseases disappear. Be careful if we get a sudden cool down
or cool moist nights, mildew is likely to pop up on some of your roses.
Most diseases must be dealt with before they get started. Applying
fungicides as a preventative will keep diseases in check.
7. Deer! If you have deer that like to visit, you know how
frustrating they are when they eat your prize rose. Spray liquid fence
as a preventative, especially in the fall when the deer are getting more
desperate for food.
8. Sun. Most roses require at least 5-6 hours of sun daily.
However, many shrub and floribunda roses can take more shade (or less
sun) than hybrid Tís. Lighter colored flowers also donít mind a little
less sun and they will hold their soft pastel colors better than being
in the hot sun all day.
9. Pruning. Donít be afraid to prune, especially older or
smaller branches that donít seem to be producing. Encourage healthy and
vigorous shoots. These will be the framework for next years rose.
Prune to keep your rose open so air can circulate. This will help
against most diseases.
