To trim back a fern, start by identifying the fronds that you want to remove. Use a sharp pair of pruning shears or scissors to carefully cut the fronds at the base where they meet the main stem.

Additionally, be sure to clean your pruning tools before and after trimming to prevent the spread of disease. **

The general rule of thumb for trimming a hedge is to avoid cutting back more than one-third of its total height or width at a time. Trimming beyond this limit can stress the plant and affect its health and growth. It's best to trim hedges regularly to maintain their shape and size, rather than allowing them to become overgrown and requiring drastic pruning. If a hedge has become severely overgrown, it may be necessary to trim it back gradually over the course of several seasons to avoid damaging the plant. **

Ultimately, the choice is yours and you should go with what makes you feel most comfortable and confident. **

Thujas, also known as arborvitaes, can be trimmed in the early spring or late summer. It is best to avoid trimming them during the fall months as this can leave them vulnerable to winter damage.

It is best to trim Thuja tips in the late spring or early summer, after the new growth has emerged. This timing allows the plant to recover and continue to grow throughout the rest of the growing season. Avoid trimming Thuja tips in the fall or winter, as this can leave the plant vulnerable to winter damage. Additionally, it is important to only trim the tips of the branches and avoid cutting into older wood, as this can harm the plant's overall health. **
