Natural Black Spot  & Mildew Control

Can you tell me how to control black spot in roses?? I would like to get a head start on this problem. Is there something natural I could spray on them to control black spot??

Cornell University did a research project using 'Baking Soda'. It works quite well with mildew and a bit on 'Black Spot'. The formula is 3 teaspoonful of Baking Soda, 1 teaspoonful of liquid detergent soap, in one gallon of water. Sprayed every 10 to 14 days during the spring and summer growing season. Dormant spraying at this time of the year with a 'Dormant Spray' will also help. Spray the rose canes and surrounding soil.

Owen's Gardens is located in Monroe. You can reach them by phone at (360) 794-6422 or they have a terrific display of their plants at the 'Northwest Flower and Garden Show', which will be held in Seattle on Feb. 19th, 20, 21, 22 and 23 at the Washington State Convention Center in Seattle.

Controlling Oxalis

Could you please help me? I have a plant in my garden that I can't get rid of. It has three leaves (Similar to Clover) has a NUT ON THE ROOT that the new plant comes from, and grows like hair on a dogs back. I have tried just about everything (Chemicals, black plastic, vinegar) to get rid of it and cannot.

Sounds like Oxalis. There are products on the market (Oxalis and Clover Killer) that seem to do a pretty good job of controlling this pest. Also, if you're persistent 'Finale' or 'Round-Up' will help keep it under control. The problem is it seeds at a very young age and the roots are also very persistent.

Calla Lilies

I cannot find info on the care of Calla Lilies, would appreciate any info you can send.

They prefer a light well-drained soil, and should be planted where they are protected from the hot mid-day sun. The small flowering (new varieties) are not very hardy and will need winter protection should the weather get cold in the region in which you live.
