Horizontal Support Netting
Horizontal support netting is a simple and effective way to keep your dahlias upright, even in wind and rain.
What You'll Need
Polypropylene or nylon support netting with 10–15 cm grid squares
Steel posts, wooden stakes, rebar, or T-posts
Cable ties or twine
How to Install
Position posts around your dahlia bed, spacing them about 1.2 metres apart.
Stretch the netting tightly between the posts and secure it firmly.
Install the first layer 30–45 cm above the ground.
As your dahlias grow, add another layer of netting every 30 cm to keep the stems supported.
Why It Works
The stems grow naturally through the mesh, which keeps them upright without restricting growth.
The netting supports heavy blooms, improves airflow, and helps prevent stems from bending or breaking.
