Q. I have two lavender plants by our front porch. I’m not sure when to trim them. One time in the fall, I pruned them back and it killed them. I replaced those and the plants are now about two years old. Should I trim/prune them in the fall or spring? If so, how much? – C.G., Knox County A. Since lavender is only marginally hardy in our area, I would wait to prune them…Read more about Prune Lavender at the Right Time[Read More]
Although the benefits of mulching garden plants are many, wood mulch that has been improperly stockpiled can lead to plant injury or even death. Young herbaceous plants are the most susceptible to such injury, which becomes obvious shortly after applying a hardwood bark mulch. Plants may look like they have been burned with fertilizer or pesticides, or possibly, are under severe water stress. All of the above could potentially be a problem, but apparently, we…Read more about Sour mulch can burn tender plants[Read More]
Q. This plant came up in my back yard last summer. It grew to over 13 feet tall. I would like to know if you can identify it. – R.D., Lanesville, Ind. A. That is an impressively tall volunteer! It is difficult to tell much detail in the photo about the flower structure, but considering the size, stem color and foliage, one possibility would be giant ironweed, Veronia gigantea. While this plant commonly reaches up…Read more about Mystery garden volunteer could be giant ironweed/Garden Soil Samples[Read More]
Now’s a good time to survey your landscape and decide what needs pruning following potential freeze injury late this winter, keeping in mind that not all plants need to be trimmed. Pruning generally stimulates new buds to develop and break dormancy, so this year we recommended delaying pruning to reduce freeze injury. We had mild conditions through midwinter, which caused some plants to emerge early from dormancy. The more recent temperatures in the teens and…Read more about Assess Pruning Needs[Read More]
To admire a peony in full bloom is a fitting way to celebrate our full arrival into spring and preview a hint of the colors that summer will bring to our gardens. Although it is native to Asia, the peony has become a staple of Midwestern flower gardens – so much so that the Indiana Legislature in 1957 adopted the peony as the state flower. Zinnia was the state flower from 1931 to 1957 and…Read more about Peony Showtime[Read More]

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…Read more about Leaves of Three, Let It Be’ Should Be ‘Leaflets of Three[Read More]

Although late winter is generally the ideal time for pruning chores, many of our spring-blooming shrubs are best pruned immediately after flowers have faded. Trees and shrubs that bloom in early spring, such as forsythia, lilac, honeysuckle, quince and spirea, set their flower buds the previous fall, referred to as “flowering on old wood.” If you prune in late winter, some or all of the bloom potential for spring is sacrificed. By waiting until after…Read more about Some Shrubs Best Pruned After Flowering[Read More]
