They spray every 7 or 10 days using a variety of products to do the job, carefully choosing chemicals to suit the problem. They do not believe in over using chemicals to cure rose problems instead preferring to use less, especially in hot weather. They fertilize with horse manure, Fertrell products, Epson salts and banana peels. Yes, that's right, banana peels, either dried or fresh, worked into the soil around the rose bush. Donna claims the banana peels help keep the Aphids under control.
Green sand is used over the winter for mineral content.
J.R. is really good at starting roses from cuttings. He takes a cutting and inserts it into damp good soil with lots of leaf mold in it, and covers it with a plastic milk jug with the bottom cut out. He then covers the jug with an old umbrella stuck into the ground. I have seen their garden overflowing with beautiful roses and growing a good crop of beat up umbrellas also. Donna and J.R. regularly attend meetings of all three clubs they belong to and also the District meetings.
