Rose Tips, March 2022

By Master Gardener and ARS Consulting Rosarian,  Judith Kafantaris

Rose bush in bloom.

Spring time and Roses are blooming.

Roses are heavy feeders especially after being dormant and now awake and getting ready to set blooms. Let us start:

Epsom Salts
Add 1/3 cup Epsom salts scattered around the base of each rose bush. The rationale is that Epsom salts help the bush to set new canes known as basal breaks. New canes are needed as the old canes age, turn grey, brittle and eventually need to be pruned away. Some roses will set new canes without any help, such as some miniatures and some shrubs. All bushes though get Epsom salt.

Compost
In the rose garden we celebrated Valentine’s Day by spreading compost in all the rose beds to a depth of 1 inch.

Fertilizers

Fertilizers have 3 main ingredients: Nitrogen, Phosphate, Potash/Potassium. Some fertilizers are balanced and have numbers such as 10-10-10 (all the same). Other fertilizers are complete and have numbers such as 2-5-3, 5-12-5, 15-30-15. The middle number is to be the highest especially for blooming plants, such as roses, tomatoes etc. ML Robinson has always said that plants do not know if the fertilizer is used for roses or tomatoes, so always check the numbers before buying. Follow the instructions on the container as to amount to spread under the bushes or in containers scratched into the soil. Water in well.

Aphids
Aphids arrive as the blooms appear on the bush and can be seen on stems, leaves, and buds. Aphids are a sucking insect and can be controlled with a spray of water from the hose. Some aphids are green although some can be black and orange. They leave a shiny coating on the leaves, buds, and stems known as honeydew, a hint that aphids have arrived. Ants are known to commander the aphids because ants feed the honeydew to their offspring. Most aphids leave when the blooms open.

Powdery Mildew
Powdery Mildew arrives when the days are warm and the evenings cool; and is a fungus that produces spores and spread by the wind. Mildew covers the leaves, stems and buds as though sprinkled with dusting powder. Some rose varieties appear more susceptible than others. Treatment choices range from fungicides to home remedies.

*Gardening in Small Places - Understanding Your Irrigation,
April 16, 2022, 9 a.m.-noon, Zoom class ($10 fee).

With the spring season upon us, it’s time to start thinking of our landscapes again, including the often-neglected irrigation. As your plants grow, and your landscape changes, your irrigation needs change, too. No one type of irrigation is good for all plants. When you have a variety of plants in your landscape, you need a varied irrigation to accommodate those plants. Hint, there is more than one type of drip irrigation. If you'd like to have a better understanding of your irrigation system, or you want to make your system more efficient, then this class is for you. Proper irrigation can prevent water waste and help you save money. Come let Professor ML Robinson help you discover the right type of irrigation for your landscape. Register at (Irrigation).

*Gardening in Small Places, Solving Your Garden Problems, May 7, 2022, 9am-noon, Zoom class ($10 fee).

You may notice holes in leaves, black spots on the bottoms of tomatoes, spots on the leaves, your squash not developing or other things. Learn about common problems in the garden, how they happen, how to avoid them and what to do about them if they occur. Register at (Garden Problems).

* For more information on the "Gardening in Small Places", please contact Elaine Fagin (efagin@unr.edu) or 702-257-5573. If expecting an email,  please check your spam and junk mail folders. Our notices are sent via Listserv emails, which sometimes go to these folders.
