  • Can I use railroad ties to form a flower bed?
    Railroad ties are usually treated with creosote. This material is no longer used due to its negative effect on human health and the environment. Instead border the flower bed with stones or a long-lasting wood like oak or cedar. You could also use timbers treated with one of the newer more environmentally friendly preservatives.
    Will the high iron content of our well water harm my perennials, shrubs or vegetables?
    The iron content in well water usually isn’t harmful to common landscape plants. This is especially true where the soil pH is 7.0 (neutral) or higher. Most soil in our area is neutral or higher.
    My bee balm and roses develop gray leaves toward the end of summer. It looks like mold and is spreading. What can I do to stop this?
    Powdery mildew is a common disease of both roses and bee balm. You could replace your bee balm with a more mildew-resistant variety. Reduce the risk of powdery mildew and other diseases by giving your plant plenty of room to grow in a sunny location. Proper spacing allows good light penetration and airflow that reduces risk of powdery mildew. Several organic controls are also on the market. Neem is labeled for controlling powdery mildew.
    Can you tell me why one yellow daisy would grow up in my clump of white daisies?
    A chance seedling or a mutation may be the answer to this mystery. Offspring of plants do not always come true from seed. It is possible that one of your white daisies produced a yellow flowering seedling or that a mutation caused a portion of the white daisy to produce a yellowing flowering stem. You can enjoy the diversity or remove the yellow stem.
    My sedum is leggy and topples over by the end of summer. Any suggestions?
    Prune your leggy sedum back halfway in mid-June. This will encourage more compact growth. The flowers will be smaller but there will be more of them.
    Is it ok to put ashes from my wood burning stove in a garden?
    Wood ash is not the best soil amendment for your garden as it tends to be alkaline which can increase the soil pH.
    My oak tree has pink fuzzy balls on it. Is this ok?
    Sounds like your tree has galls. There are many types of galls that affect oak. Insects cause these growths as they feed. The galls contain seed-like structures and look ‘lumpy.’ The damage is only cosmetic and won’t harm your tree.
    Page 2 of 2 - My Stella de’Oro daylilies are suppose to bloom more than once. I have only an occasional second bloom. What’s wrong?
    Dig and divide daylilies every three or four years to keep them blooming. Add a bit of compost to the planting area before you put the divisions back in the garden.
