Pest and Disease Control

Choose insect and disease resistant varieties when possible. Keep the garden clean, neat, and weed-free, and be alert for early signs of trouble to reduce the need for pesticides. To prevent the spread of leaf diseases, water in the morning or early enough in the evening so foliage has time to dry before dark. Soapy water or insecticidal soap will control many insect pests. Read all label directions before buying or using any pesticide, and follow all precautions.

Like most gardeners, I love watching the various butterflies that visit my garden.

Let’s face it. Sometimes we need a quick, inexpensive bouquet of flowers to give to a friend or family member or to freshen up our own spaces.

Variegated burgundy and chartreuse coleus laves fill a container.​
Filed Under: Flower Gardens June 25, 2018

Since we celebrated the first day of summer last week, I think this is the perfect time to talk about one my favorite color plants, the coleus.

Coleus used to be that colorful plant that would grow only in the shadows, never exposed to the sun. One of my favorites of this kind is the sun-bashful coleus group, Kong.
