Though your aching back may not agree, recent heavy snows actually will be good for your garden and landscape. Snow provides moisture as well as protection from cold and wind. Snow is an excellent insulator against low temperatures and excessive winds. The extent of protection depends on the depth of snow. In addition, the soil gives off some heat so that the temperature at the soil surface can be much warmer than the air temperature. […]
Q: I’m having an argument with my wife about a plant in our yard, and we hope you can help arbitrate. I’ve sent a photo of a plant that we found growing near some shrubs. Neither of us remember planting it. My wife thinks it’s pretty ground cover and that we should let it stay. I think it’s a weed and that we should get it out of there before it takes over the whole […]
By selecting Stachys officinalis ‘Hummelo’ as its 2019 Perennial Plant of the Year, the Perennial Plant Association once again continued its focus on pollinator-friendly plants. ‘Hummelo’ is a compact, clump-forming perennial, reaching 1.5 to 2 feet tall and wide.

Although some folks may be sad to see summer coming to a close, many gardeners are looking forward to harvesting their sweet potato treasures. Sweet potatoes are warm-season plants that are very sensitive to cold temperatures. The tuberous roots should be harvested by the time frost kills the vines or soon thereafter. Sweet potato roots continue to grow until frost kills the vines. Roots can be left in the ground for a short while; […]
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, […]
Q. I saw these holes in my tree and am wondering what they are from. This tree is the only one I have seen them on. – M.S., Chesterton Some species of woodpeckers cause large holes in tree trunks. A.

The eastern red cedar is a juniper, rather than a true cedar. Known […]
