(Solidago rugosa)

Wrinkleleaf goldenrod, also known as Roughleaf goldenrod

Native to North America, this perennial herb is recognized for its tall, stiff stems and rough, hairy leaves. For optimal growth and health of wrinkleleaf goldenrod, gardeners should prune in early spring to promote new growth or in summer to remove spent flowers and prevent unwanted self-seeding. Cutting back the plant by one-third can encourage a bushier appearance and enhance flowering. Pruning also helps maintain airflow, reducing the risk of fungal diseases. Always use clean, sharp tools for clean cuts.

What Are the Benefits of Pruning Wrinkleleaf Goldenrod?

Pruning wrinkleleaf goldenrod encourages vigorous growth and maintains its desirable shape. Removing older stems or spent flowers stimulates new, healthy shoots and a more compact form, optimizing the plant's vitality and aesthetic appeal.

What Is the Best Time for Pruning Wrinkleleaf Goldenrod?

Spring

Summer

The best time to prune wrinkleleaf goldenrod is in late spring to early summer after flowering since plants typically start their active growth phase in spring. Pruning during this period encourages healthy new growth and allows gardeners to shape the plant and control its size. It also helps prevent the spread of plant diseases, as fresh cuts can heal more quickly in active growth phases, reducing the risk of infection. Furthermore, trimming after the flowering season allows gardeners to remove spent flowers, which can encourage a second bloom in some species and improve the overall vigor and appearance of the plant.

Over pruning

Removing too much foliage can stress wrinkleleaf goldenrod, leading to reduced vigor and flowering potential. Aim to prune no more than one-third of the plant at a time.

Blunt tools

Using dull or unclean pruning tools can cause damage to wrinkleleaf goldenrod's stems, leaving jagged cuts that are susceptible to pests and diseases.

Wrong cut location

Cutting either too close or too far from the bud can impair healthy growth. Cuts should be made just above a leaf node or set of leaves.

Neglecting deadheading

Failing to remove spent flowers from wrinkleleaf goldenrod inhibits new bloom production and can result in a less tidy appearance.

Ignoring shape

Not considering the natural form of wrinkleleaf goldenrod during pruning can result in an unnatural or lopsided appearance and affect the plant's overall health.

Stripping interior

Over-zealously thinning the interior of wrinkleleaf goldenrod can decrease the plant's foliage density too much, reducing its ability to photosynthesize effectively.
