We have looked at growing roses at home previously. If you have planted roses and lovenly nurtured them to grow. There is nothing worth then discovering rose diseases have crept into your prize roses.
To make sure that your prized roses remain in the best of health, simply follow these tips.
Black Spots on Leaves
This disease is commonly known as black spot. Black spots appear as circular with fringed edges on leaves.
They cause the leaves to yellow. Remove the infected foliage and pick up any fallen leaves around the rose. Some artificial sprays may be used to prevent or treat this kind of rose disease.
Stunted or malformed young canes
Known as powdery mildew, this is a fungal disease that covers leaves, stems and buds with wind spread white powder.
It makes the leaves curl and turn purple. Spray with Funginex or Benomyl to treat this fungal disease.
Blistered underside of leaves
Known as rust, this disease is characterized by orange-red blisters that turn black in fall. It can survive the winter and will then attack new sprouts in the spring.
Collect and discard infected leaves in fall. A Benomyl or Funginex spray every 7-10 days may help.
Malformed or stunted leaves and flowers
Spider mites causes this problem. They are tiny yellow, red or green spiders found on the underside of leaves where they suck juices.
The application of Orthene or Isotox may help in treating this infestation.
Weak and mottled leaves with tiny white webs under them
Aphids cause this problem. These small, soft-bodied insects typically appear brown, green, or red
Often clustered under leaves and flower buds, they suck plant juices from tender buds. Malathion or diazinon spray may help roses to survive these bugs.
Flowers fail to open or open in a deformed way
Thrips could be the reason behind this problem. They are slender, brown-yellow bugs with fringed wings that also suck juices from flower buds.
Cut and discard the infested flowers. In some cases, Orthene and malathion may also treat this problem
Remember that roses are hungry feeders that require a lot of fertilizer to become healthy bushes. Rose diseases do not mean you have to get rid of your prized roses.
Give your roses some TLC, and you can deal with any rose diseases you might find.
