It is unlikely that…Read more about Question and Answer[Read More]
Although recent rains have relieved many gardeners from their watering chores, the respite is sure to be temporary.

Now’s the time to prepare your garden roses for the coming growing season. The three primary purposes of pruning are to remove damaged and unwanted canes, promote optimum blooming and reduce size of the plant, if needed. Roses are best pruned before the new foliage emerges so that you can easily assess winter damage. Winter mulch and foam covers should be removed as soon as new growth becomes apparent.

Chlorotic (a yellowing of the leaves) azaleas and rhododendron are a common sight in the Indiana landscape. The term chlorosis gets its name from the lack of chlorophyll, the pigment responsible for healthy plants’ green color. One major cause of chlorosis is a deficiency of either iron or manganese. Other landscape plants such as pin oak, river birch, holly and sweet gum are also susceptible to chlorosis. Iron deficiency leads to a pattern of yellowing…Read more about Interveinal Chlorosis on Azaleas and Rhododendron[Read More]

Q. In an earlier In The Grow Column you were writing about possible replacements for white pine trees in Indiana. Yet you did not mention Eastern red cedar as a possibility. Is there something wrong with the native species of evergreens? A. Eastern redcedar is actually a species of Juniper rather than a true cedar. It is widely adaptable to various stresses, especially drought, so it can be very useful for group plantings, windbreaks and…Read more about Question and Answer[Read More]
