Trimmit Plant Growth Regulator

Trimmit Growth Regulator – Long-Term Hedge & Shrub Control

Shape once, enjoy for months.
Trimmit is a systemic plant growth regulator formulated with Paclobutrazol (250 g/L) to slow and manage new shoot growth in ornamental hedges and shrubs. By reducing internode length and promoting earlier bud formation, Trimmit delivers a neat, compact appearance that lasts season-long — cutting pruning frequency and labour in half.

Used by professional landscapers and councils, it’s ideal for maintaining species like Murraya, Syzygium, Photinia, and Duranta, producing denser foliage and a cleaner finish with less trimming required.

How much to apply:

• Hedges up to 2 m: Mix 0.5–2.5 mL per L of water per plant, adjusting for species and size.
• Apply as a root drench at the base of the plant in late winter to early spring when new growth begins.
• Lightly irrigate after application and avoid pruning for 4–6 weeks to allow full uptake.
• Do not treat stressed or recently transplanted plants.

Trimmit works below the surface to redirect energy into root and bud development, enhancing colour, thickness, and long-term structure without compromising plant health.
