Renewal pruning has immediate, delayed rewards
Q: I have 2 Forsythias, 2 Spireas, a Ninebark and a variegated Dogwood that appear to be half dead. My thought is to cut them down now to regrow so they’ll have all summer to do this. What are your thoughts? Last year all of these bushes were lush and full. A: Although it could be done now, late winter is the ideal time of year to completely cut the shrubs to the ground. But […]
Assess Pruning Needs
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 […]

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 […]

Spring Pruning of Roses
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. Since a spring freeze is still […]
April “In The Grow”
Q. I’ve been out in the backyard giving myself a backache chopping down ornamental grasses. We love them 363 days a year; every day except for the two that we spend chopping them down and getting rid of the debris! Any thoughts? – Amy Raley, West Lafayette, Ind. A. We buzz down our ornamental grasses with electric hedge shears and a chain saw. The task goes by quickly! We leave the dried grasses in place […]
