Can all shrubs be pruned hard the same way as forsythia?
Q. Can all shrubs be pruned hard the same way as forsythia?
A. Forsythia is a shrub I put in a class I call “The Many.” That means when you look at the plant, it has many stems growing out of the ground (4-5 or more), rather than just one or two.
Most forsythia clearly have many stems coming out of the ground.
Other plants commonly grown in mid-Michigan that have many stems are:
- Spirea,
- Lilac,
- Dogwood,
- Deutzia,
- Potentilla, and
- Privet
Some varieties of Hydrangea, Viburnum, and Barberry have a few branches and others have many. Don’t get too concerned; just look at them and it will be clear if they are “many stems” or “few stems”.
The reason I bring these other plant varieties into the conversation is because they will respond well to the same care (i.e., rejuvenation pruning or hard thinning).
Why is this important?
Plants with many stems need to be thinned hard. By doing so, you will encourage new tender shoots to come out of the ground. Thinned hard means cutting the largest, oldest stems out as close to the ground as possible. This could entail removing up to a third (or even half!) of the stems on an annual basis. But don’t worry, this type of pruning will keep them from becoming overgrown.
