How do I choose the right grafting clip?
Grafting clips are used for various kinds of plants, especially for tomato, pepper, egg plant, cucumber, zucchini and (water)melon. Each type of seedling needs different growth conditions which makes it important to choose the appropriate clip. In this article our specialist explains the different types of grafting clips further and he’ll help you choose the appropriate grafting clip for your type of plant.Grafting clips for tomato, sweet pepper and egg plant
The choice between a hard or soft grafting clip for grafting tomatoes, peppers and egg plant depends on growth conditions. In Mediterranean countries more rigid clips are preferred over more flexible, softer clips because of the cultivation of fairly tough plants. The flexible, soft clips are the preferred choice in the moderate climates.
Rigid grafting clips
Models PT2, PT3, PT4 and PT5 are fabricated from sturdy plastic. Each model has different characteristics:
- PT2: this is a rigid clip with a round opening. Available in sizes 1.2-3.5 mm.
- PT3: this is a softer clip with an oval opening*. Available in sizes 1.2 -3.5 mm.
- PT4: this is a rigid clip with support and an oval opening. Available in sizes 1.5 – 2.7 mm.
- PT5: this is a rigid clip with an oval opening*. Available in sizes 2.0 - 3.0 mm.
* An oval opening offers more flexibility with difference in diameter between lower and upper stem.
Soft grafting clips
Models PT7, PT8 and PT9 are fabricated from softer/flexible material and are a good substitute for silicone grafting clips. Each model has different characteristics:
- PT7: this is a soft, flexible clip. Available in sizes 1.2-2.5 mm.
- PT8: this is a soft, flexible clip with stick support. Available in sizes 1.3 – 2.5 mm.
- PT9: this is a soft, flexible clip with ridges on the ends. This provides extra grip and makes working with it easier. Available in sizes 1.0 – 2.5 mm.
Grafting clips for cucurbits
There are two grafting methods for grafting cucurbits: the approximation clip or the splicing clip ( also known as the Japanese grafting method). There are grafting clips available for both methods.
Approximation graft
The PS2 or PS3 grafting clip can be used when an approximation clip is needed.
- PS2: this clip is available in the 10mm size.
- PS3: This is by far the most sold clip for the approximation graft. This clip is available in sizes S, M and L.

Splicing graft or Japanese grafting method
For the tip graft or Japanese method one can utilize the PS1 or PS7 clip. These clips have sufficient strength to keep the grafted plants approximated well without a support stick, which offers saving on labour and materials.- PS1: this clip is appropriate for various stem thicknesses. Available in size 7 mm.
- PS7: this clip is appropriate for smaller stem thicknesses. It is by far the most used grafting clip for tip grafting of cucurbits. Available in size 6 mm.
Grafting clips for roses
One can also use grafting clips to graft roses. These grafting clips replace grafting clamps. In addition, these small, powerful clips don’t have to be removed from the young plant after the graft cultivation. These clips are available in sizes XS, S and M.
Different colours
All grafting clips are available in different colours: natural, red, green, yellow, blue, purple, orange and black. This gives an advantage when different sizes and kinds of clips are used. The colours enable you to easily distinguish the clips from each other which leads to fewer mistakes.
