It’s For The Birds


Q: I would like to plant bushes that will attract birds in fall and winter. I’m thinking of something that produces a berry they eat? – J.W., Winfield, Indiana A: Birds require not only food such as fruits and seeds, but also shelter and water. Planting a variety of plants that offer these resources across the seasons will help attract more birds to your yard. Some native shrubs to consider include: Aronia (chokeberry) Callicarpa (beautyberry) […]

What’s killing the oak trees?


Q. In 22 years I’ve had more than a dozen oaks die because of a grub or larvae. Symptoms: First the leaves die and turn brown at the top of the tree. It slowly spreads down the tree until all the leaves are brown and have fallen off. Then the bark begins to peel away from the trunk, and then it falls off pieces at a time. You can see where it cuts off the […]

Gardeners worn down; clearweed may be culprit


Q: I have had a garden on our property for about 14 years. Naturally, we’ve always had to deal with weeds, but until last year they had been the usual crabgrass and other types that could be controlled if you kept ahead of them. But last year, some type of weed or ground cover has sprung up, and it’s infuriating!! There is absolutely no way to weed it out by hand because it comes up almost […]


Blue spruce not a great choice for Hoosiers


Q: We have 5.5 acres with several hundred white pines, 7 blue spruce, and 2 red pines. Several of the blue spruce are dying. Several years ago, two started dying from the bottom up. We put evergreen spikes around them, and after a year or so they came back to normal. Presently some of the large ones are now dying from the bottom to the top. We put spikes around two large and one small, […]


Damage control for the yellowstriped armyworm; Transplanting trees from the woods


Q. I have a worm eating my flowers. The flowers are in a tall planter so I am wondering if I need to add something to the base of the planter to keep them from coming up the plants OR are they hatching out on the plants? Some of the damage is caused by small slugs as well.Can you tell me what kind of worm this is? Also, what do you recommend to deter them? – […]


Peeling sycamore tree bark is normal; Top heavy hydrangea plants; Should I treat my lawn for Japanese Beetles


Q.  We have a large sycamore tree in our yard. Every summer it sheds its bark over a few weeks’ time. I think as it grows it is growing new bark and losing the old bark. Am I correct? – J.C., Walton, Ind. A.  You’re on the right track. Peeling bark is normal, and is a key ornamental characteristic for a sycamore, also known as American planetree. The bark starts out a bit gray-brown and as the […]


Roses: A Feast For Many Insects/Mystery Plant ID/Why Hydrangea Flowers Fade Pink to Tan


Q. How can I keep the beetles away and keep the invisible insects from eating holes in my rose leaves? The beetles have not been too bad the last couple of years, but the holes in the leaves never stop. I have tried so many different kinds of insecticides but to no avail. Our soil is not too sandy, but it is not all dirt either. Drainage does not seem to be a problem as […]


Weed or flower? Sometimes it’s in the eye of the beholder


Q) This flower/weed came up in my flower garden this year. I know that I did not plant it and two other people said that they have it growing in their yards also. I took it to our local nursery. They did not know what it was and looked it up in their books but could not find it. They gave me a few suggestions but when I looked them up on the internet, they […]


Best fruit tree for central Indiana / What to do about moles?


Q. Do you have a suggestion of a good/easy to grow fruit trees in the Indianapolis area? Any tips on the “how to” will be appreciated. – N.D. A. A dwarf, scab- resistant apple cultivar would likely be the best adapted of the fruit trees for the central Indiana area. There are quite a few cultivars to choose from. Most apple cultivars require cross pollination from a compatible cultivar in order to reliably set fruit. It […]


Leaves of Three, Let It Be’ Should Be ‘Leaflets of Three


Most gardeners have heard of the wise advice “leaves of three, let it be” referring to the pest plant poison ivy. While not quite as catchy, the saying really should be “leaflets of three, let it be.” Poison ivy leaves are compound rather than simple – a single leaf is divided into three separate portions, called leaflets. Plants with three leaflets are often referred to as being trifoliate. Another key identifying characteristic is that one […]
