With temperatures in the low 90’s summer
is here in Central Florida. Your
roses will not be at their best for the next 4 months. However, they will
continue to produce some nice blooms, if you keep in mind that they need plenty
of water during the hot weather.
also need regular protection against black spot and spider mites.
Continue your weekly spraying for black spot using Cleary’s 3336 and
Dithane or Funginex and Dithane, or you may prefer to alternate these.
down the underside of the foliage under pressure at least twice a week to
control spider mites. You may use a water wand or a regular hose nozzle for good
results. The roses will love a good bath anytime during the hot weather as long
as the foliage dries before night falls. Wet leaves over night will encourage
the spread of black spot.
Rosarians continue their regular fertilizing program of feeding every two weeks
during the summer months, while others prefer to cut back on the amount of
chemical fertilizers used. I prefer the latter approach.
I use chemical fertilizers about once every four weeks during the hot

weed will really multiply. Save your back as much as possible by using Round-up
or some other weed killer. But be careful to protect your bushes, or they will
get damaged. Summer is a good time
to propagate. Try rooting some cuttings this summer. Use a jar or plastic
covering to keep the cutting moist and use a light potting soil and you should
have good success. If you use a rooting compound on the planted tip of the
cutting after roughing it up a bit, you will increase your success. I get a lot
of satisfaction from starting new rose bushes, and I believe you will too.
