Sensational Shrubs

What is a sensational shrub? I believe it’s a shrub that features striking characteristics multiple times a year, or as my friend Lee May puts it, “they multi-task.” Whether it’s flowers, fragrance, foliage, or winter interest, a sensational shrub will provide your garden with interesting qualities throughout the year. Fothergilla x gardenii ‘Blue Shadow’ fits perfectly into this category.

Spring is on the fast-track over much of the country and with it blooms abound. It’s been quite entertaining and worrisome at the same time. Still plenty of time for hard frosts and freezing temps. One of spring’s early bloomers is Fothergilla. This shrub typically blooms in early spring (April to early May) but has been blooming for me since mid March. I love the small pom pom blooms composed of tiny bottlebrush spikes. The white flowers are echoed in the many dogwoods currently in bloom. They feel light and fresh. To me, they symbolize a start to a new beginning.

As new leaves emerge, they appear powder blue– an effect caused by the silver-grey felt which covers them. The foliage will become leathery and broad as it transforms to a striking blue to blue-green throughout the growing season, changing to brilliant shades of red, orange, and yellow in autumn. You might even see some purple in the final act.

Fothergilla ‘Blue Shadow’ is a compact slow-grower. It will grow 4-6’ tall and as wide for the first 10 years. So far, there are no known serious insect or disease problems. Try Fothergilla and put a little white in your life this spring. I’m looking forward to following its progress all year.

Say No To Mulch Volcanoes

‘Mulch Volcano’ is term used to describe a deep pile of mulch around the base of a tree or shrub that forms a mound or volcano shape. You see them everywhere, especially on or around commercial properties, as grounds crews and gardeners alike are busy applying hardwood mulches to beds, borders and trees.

Generally speaking, there are many benefits to mulching, but I wonder if people see these volcanoes and think it s ok to copy this? It most certainly is not and there are several reasons why one should avoid it.

 

The consequences of overmulching trees and shrubs:

Piling soil, mulch, or both, against the trunk flare has been shown to prevent needed gas exchange causing the inner bark tissue (phloem) stress, dysfunction and subsequent root stress.

Overmulching can promote excessive soil moisture which can lead to root rot.

Fungal and bacterial diseases, crown and butt rot can also be caused by excessive mulching.

Mulch that touches the trunk of a tree can lead to rodents chewing on the bark as well as insect problems.

 

So, what s the proper way to mulch? Follow these guidelines:

Apply the mulch to the surface of the soil anywhere from 2 to 4 inches thick.

Do not allow the mulch to touch the trunk or stems. Keep it about 3 to 6 inches away.

Apply the mulch from the center of the tree to the dripline if practical. Otherwise, at least a 3-foot radius around the trunk.
