Positioning of the clip calculated

Positioning of the clip calculated

Technical

 

There are different explanations as to why many growers are using wire or plastic clips instead of twisting.  It is totally dependent on the natural vigour of the plant or in fact the growth pattern of the plant.  Some varieties will grow directly up, with leaves pointing upwards, making the procedure of twisting easy or it could be quite the opposite for alternate varieties.   

There are differing opinions as to where to attach a clip.  Although, I think we all agree never directly above the truss for tomato plants.  Let’s take tomatoes as an example, you can place the clip either under the middle leaf or directly under the truss.  A minor problem with placing the clip under a leaf, is that this may slow down the de-leafing process, if you cut leaves.  Clips sometimes get in the way when cutting a leaf. You can cut the string higher up the stem, to release tension so the clip slides down the stem making it is easier to cut the leaf cleanly.

For large loose tomato varieties, that require removing the empty truss, it can be a pain to have clips under the truss but for some cherry tomato varieties, where it is not necessary to remove trusses, it makes sense to always clip under the truss.  I picked a cocktail truss for three seasons and it was easier in that circumstance to have the clips placed in between the leaf and not under the truss.  So a horses for courses approach.

Clip placed directly above the truss.  This is totally avoidable.

Advantages of Clipping:

 

Clipping is extremely useful if you get behind with twisting or if the variety grows at right angles.  I am extremely impressed with the Tomsystem, which uses a steel ring instead of a plastic clip. However, if the work falls behind it can become a tangle, and then the plastic clip, regardless of being slower, is the preferred option. 

Clipping is also much easier on the plant than twisting. It allows a much faster recovery from the stress of cells being strangled around a string, especially in the warmer months.  

It may seem a minor detail but if you don’t put the clip in the place that suits your particular variety it could cost you labour hours somewhere in the chain.  Every variety will require something different that suits your operation.  This small amount of attention to detail, in a competitive market, is important as businesses strive to improve.

Not the end of the world for the position of this clip, however, as this is a cherry tomato, I would prefer it under the truss as per below.
