IT’S TIME TO CUT BACK

My cutting back period is typically Valentine’s Day to St. Patrick’s Day and this week I chose to cut back lavender, my bird topiary, and a bunch of grasses, so I can prepare for planting.

Before lavender is cut back

Lavender is one of those evergreen woody ‘perennials’ that needs to be cut back hard every year to regenerate the plant-right down to new growth closest to the center of the plant. Otherwise lavender turns into a twisted mess of wood in about 5 years and you have to replace it.

After being cut back-and even then maybe it could be cut back more sharply.

I trimmed the bird topiary lightly and then took a photo to study its shape. Note my red lines which are the guide for its final trim.

Red lines help guide how I’d like to improve its shape.

Even dried grasses have a wintry presence. Wait until late winter to cut back.

Big, bold grasses add structure even during the winter.
Smaller grasses add texture and increase the definition of evergreen shrubs.

When I trim grasses, I do so knowing the trimmings will be chopped and used as mulch, not taken away to become compost elsewhere.

Plenty of grasses mean plenty of mulch for plants that need protection from evaporation during hotter days.
One last thing to remember, there’s a different technique for cutting back herbaceous grasses from evergreen grasses. On the left is Japanese Blood Grass (and prefers moist soil). It turns brown in winter. Cut it back to about 3″. On the right is Sesleria autumnalis (which tolerates drier soil). It is evergreen but has some die-back which makes it unattractive. Cut it back to 6″. Don’t cut it too short or it can die from crown rot.

Fern Bench Progress

 With the help of my son and his friend, a new box for plants is now part of the bench. After trimming the coir to fit snugly into place, I’m ready to plant ferns! Some details of the process:
