 Last week I was delighted
to hear you mention the motion sensor sprinklers for deer. I have been trying
to find some for well over a year. Can you please give me some suppliers?
 Sorry, I do not have a specific
source for the sprinklers. The ones my son uses came directly from a wholesale
nursery supplier. Even at wholesale, they were fairly expensive (about $70
each as I remember). You can order them directly at the website
http://www.scatmat.com/scarecro2.htm
or ask a local nursery to order them for you.
There are small orange dots
all over the leaves of my raspberry bushes. I'm guessing it's some
type of fungus. I've also noticed some tiny (1/4") white and black caterpillars
munching on the leaves.
Is there anything that can be done? I really don't like the idea of spraying
any chemicals on the plants since a lot of berries have already started.
The orange dots are probably
rust, although they could also be copper spot disease. For rust it is best
to cut back the old raspberry canes as soon as they have fruited. Throughout
the season pick-up all fallen leaves and discard them. Then in the fall cultivate
around the raspberries to eliminate the infection source. You can pick off
the caterpillars or treat them with a vegetable dust or spray. Most 'Vegetable'
type sprays or dusts are quite environmentally friendly. Read and follow
label instructions.
How do I train, prune, my
new wisteria to stay a tree shape? I purchased it this spring and would like
it to have the tree form. Please help if you can.
First, you train it up a post
or pipe, when it grows to the height you want simply pinch out the tip, top
growth. Then as it forms the tree shape, prune and thin much like you would
any tree. If the branches get too long and begin hanging too close to the
soil, prune them back in an informal shape.
We would like to know what
we can do about black spots (and sometimes the entire leaf) of our roses
turning black. It appears to only be on our heirloom rose. Any suggestions?
I am told the American Rose
Society recommends Ortho's Funginex for the control of Mildew and Black-spot
on roses. Read and follow label instructions.
