A daisy dilemma

I planted a perennial garden several years back. In the past two years, the Shasta daisies have spread and are taking over the whole garden. I have dug several up but the roots are numerous. Should I just spray them to kill them?

DaisiesWhen you read comments about Shasta daisies on garden websites, it’s clear that gardeners either love them or hate them. Love them because these daisies (Leucanthemum, in botanical nomenclature) are easy to grow and bloom reliably year after year; hate them because they can be aggressive and can, indeed, muscle out plants that are more well-behaved.

Rose of Sharon is an easy summer favorite

I remember a large Rose of Sharon shrub that grew in my grandmother’s yard that had big, pretty flowers every summer. I’d like to have one for my own garden. Can this shrub be started from cuttings?

Lil Kim Proven Winners

Lil’ Kim Rose of Sharon (H. syriacus) from Proven Winners Plants.

The old-fashioned rose of Sharon, or shrub althaea (Hibiscus syriacus), is easy to grow, and often pops up in unexpected places from dropped seeds. It can also be propagated from stem cuttings. Here are general guidelines for taking cuttings of rose of Sharon and other woody ornamentals:

Cut lengths of softwood (soft, succulent new growth) or semi-hardwood (partially mature wood of the current season’s growth) about six inches long from a healthy host plant. Remove the bottom leaves, and dip the cut ends in rooting hormone powder. Stick the cut ends about one-third their length into a rooting medium that drains well, such as perlite or vermiculite. Cover the cuttings with some sort of plastic covering to maintain a humid environment, and place them in indirect light.

Keep the rooting medium moist until roots develop. It will likely take several weeks, but you’ll know the cuttings have grown roots when you tug gently on the cuttings and feel resistance. Transplant them into containers to allow them to grow to a larger size before you plant them in the garden.

Rose of Sharon grows and blooms best in full sun, and thrives in almost any well-drained soil. Once established, it tolerates heat and drought. Flowers bloom on new growth, so if it needs pruning, you can do that task in winter.
