What Tools Do I Need to Prune Shrubby St. John's Wort?

Hand Pruners

For selective thinning and shaping of shrubby St. John's wort, utilize hand pruners, also known as secateurs, which enable precise cuts on smaller stems and branches typically under 1/2 inches in diameter. Ensuring they are bypass pruners will help make clean cuts that promote faster healing.

Loppers

Loppers, especially bypass loppers, are suitable for cutting through thicker branches of shrubby St. John's wort up to 1 1/2 inches in diameter. Their extended handles provide the necessary leverage to cut through denser wood while minimizing plant damage.

Pruning Saw

For branches exceeding 1 1/2 inches in diameter, a pruning saw is essential for making clean and efficient cuts without harming shrubby St. John's wort. A folding saw or a bow saw can be employed, depending on the branch thickness and accessibility.

Gloves

Wear sturdy gloves to shield hands from thorns and rough bark while trimming shrubby St. John's wort. Protection is crucial for ensuring safety during the pruning process.

Cleaning Solution

Sanitize all pruning tools before and after use with a mixture of 1 part bleach to 9 parts water to prevent disease spread and maintain the health of shrubby St. John's wort.

How to Prune Shrubby St. John's Wort

Step1: Optimal Pruning Time Selection

Choose the appropriate time for trimming shrubby St. John's wort, generally late winter or early spring before new growth commences, to minimize plant stress and reduce the risk of disease or pest infestation.

Step2: Sterilization of Pruning Tools

Sterilize pruning shears or scissors with a solution of 1 part bleach to 9 parts water to prevent the spread of diseases between plants.

Step3: Cutting Dead Stems at an Angle

Begin pruning by removing any dead stems. Make cuts at a 45-degree angle, approximately 1/4 inch above a healthy bud or leaf cluster to encourage new growth.

Step4: Weak Twig Removal for Better Growth

Identify weak twigs, which are typically thinner and may not have bloomed the previous season. Trim these twigs back to their origin point or to a strong outward-facing bud to enhance air circulation and light penetration.

Step5: Damaged Branch Excision

Inspect shrubby St. John's wort for damaged branches caused by weather, pests, or disease. Carefully remove these branches by cutting just beyond the break or diseased area, ensuring you cut back to healthy wood.

Step6: Desired Plant Shaping

Shape shrubby St. John's wort as desired after removing dead, weak, and damaged parts. To maintain a natural appearance, make selective cuts to reduce the shrub's size without altering its overall form.

Step7: Old Stem Thinning for Rejuvenation

Thin out some older stems to rejuvenate shrubby St. John's wort. This encourages new stem growth from the base, resulting in a healthier and more vigorous plant. Cut selected older stems down to the shrub's base.

Step8: Post-Pruning Clean-up
