What shrubs should not be pruned?

When it comes to pruning shrubs, it’s important to know which ones should not be pruned in order to maintain their optimal growth and blooming potential. Spring flowering shrubs such as Forsythia, Lilac, New Mexico Privet, Spirea, Flowering Quince, and many others fall into this category. These shrubs produce flowers on the previous year’s growth, also known as old wood. Pruning these shrubs in the wrong season or removing too much old growth can greatly reduce or even prevent flowering altogether.

One example of a spring flowering shrub that should not be pruned is the Forsythia. This vibrant shrub is known for its stunning display of bright yellow flowers that signal the arrival of spring. Pruning Forsythia in the wrong season can result in the loss of these beautiful blooms. It’s best to wait until immediately after the shrub has finished flowering before considering any pruning.

Lilacs are another prime example of a shrub that should not be pruned indiscriminately. These fragrant shrubs are cherished for their clusters of colorful and aromatic flowers. Pruning Lilacs at the wrong time can disrupt their blooming cycle and result in a lackluster display. It’s recommended to prune Lilacs immediately after they finish flowering, allowing them to produce new growth and set buds for the following year.

The New Mexico Privet, also known as Desert Olive, is a popular shrub in arid regions. This shrub produces delicate white flowers that give way to dark berries. Pruning the New Mexico Privet at the wrong time can remove the potential for these flowers and berries. It’s important to wait until after the shrub has finished flowering and the berries have ripened before considering any pruning.

Spirea is another shrub that should not be pruned if you want to enjoy its beautiful blooms. With its clusters of small, dainty flowers in a range of colors, Spirea adds a touch of elegance to any garden. Pruning Spirea at the wrong time can result in a lack of flowers. It’s best to prune this shrub immediately after it has finished blooming, allowing it to produce new growth and set buds for the next season.

Flowering Quince is a stunning shrub that produces vibrant flowers in shades of red, pink, and orange. Pruning this shrub at the wrong time can remove the potential for these eye-catching blooms. It’s recommended to prune Flowering Quince immediately after it has finished flowering, allowing it to develop new growth and set buds for the following year.

It’s important to avoid pruning the branches of spring flowering shrubs such as Forsythia, Lilac, New Mexico Privet, Spirea, Flowering Quince, and others. These shrubs produce flowers on the previous year’s growth, so removing old growth can greatly reduce or prevent flowering. By waiting until after these shrubs have finished flowering before considering any pruning, you can ensure that you’ll be able to enjoy their beautiful blooms year after year.
