Size

These heavy-duty plant clips snap onto trellis twine, string, or support wire to hold plant stems upright as they grow. Each clip is moulded from UV-stabilized plastic with a rounded opening.

They suit a wide range of plants and growing setups, and come in packs from 25 to 1000 clips, so you can buy what fits the job, whether that's a single houseplant, a backyard garden, or a full commercial crop.

Key benefits

  • Round, stem-friendly profile: The rounded opening supports the stem without crushing it, lowering the risk of girdling as the plant thickens through the season.
  • One-handed snap closure: Opens and closes with one hand, so training a long row or moving a clip up a growing stem takes seconds each.
  • Reusable season after season: Durable enough to reuse year after year, so a single pack lasts for years rather than being thrown out.
  • Better airflow and access: Training plants upright and off the ground keeps the canopy open, which improves airflow and light and makes the plant easier to reach.

How to use plant clips

Place a clip on the main stem just below a leaf node or branch, at the Y junction, so it rests against the joint and won't slide down. Add a fresh clip as the plant gains height rather than moving one too far up the stem.

String and twine trellis: Run vertical twine from an overhead wire or frame down to each plant. Clip the stem to the twine at each new set of leaves, roughly every 20 to 30 cm (8 to 12 inches), to keep it trained straight up.

Stakes, cages, and frames: Secure the stem to a stake, cage ring, or wire frame the same way. The clip carries the weight, so heavy fruiting branches are less likely to snap.

Greenhouse and high tunnel: In protected culture the clips pair with overhead string systems and suit the lower-and-lean method, holding the stem to the string as it's dropped and shifted along the row.

Cattle panels and outdoor arches: A cattle panel makes a strong outdoor trellis, run vertically or bent into an arch, and these clips work great to train stems up it as they climb. Lifting plants up off the ground opens the canopy to better airflow and light, which helps them stay productive later into the season. For sprawling crops like cucumbers and small melons, that improved airflow also eases the powdery mildew pressure that often cuts outdoor crops short.

Crops and growers it suits

The clips work on most stems that need training or support: tomatoes, cucumbers, eggplant, peppers, pole beans, peas, melons, squash, and climbing flowers. They fit growers at any scale, from home and raised-bed gardeners to market gardens, greenhouse and high-tunnel operations, and commercial vegetable production. Cannabis growers also use plant clips to train and support stretching plants.
