Answer: Hi Vicky, While perennials sometimes will successfully break through a thick layer of mulch, other times damage will result. Don’t take a chance with the health of your perennial flowers!
In late winter or early spring (depending on the weather) you should begin checking to see whether the ground is thawing or not. If the ground is thawing, leaving landscaping mulch on top of your perennial flowers can smother them — so it is time to remove the mulch, to let your perennials breathe.
Once the perennial flowers have pushed up (so that you know where they are) and have achieved a bit of height, then you can re-apply mulch around them to suppress weeds.
Question: Jimmie, Is there a general rule of thumb for when to prune flowering shrubs? I know your super busy so I appreciate your time! Susan P. in Prosper
If you are pruning flowering shrubs to rejuvenate them, the best time to prune is late winter or early spring. True, pruning early-flowering shrubs at this time will reduce or eliminate blossoming in spring that year, but the trade-off is in gaining healthier, more vigorous flowering shrubs for the long run. Until next time …Happy Gardening!!
