Should a surfactant or wetting agent be added when applying UGF6in1 as a foliar spray?

Should a surfactant or wetting agent be added when applying UGF6in1 as a foliar spray?

A wetting agent or surfactant may help more evenly disperse UGF 6-in-1 (fish/kelp emulsion) more so over the leaves, although we are not aware of anyone that has used a wetting agent, thus far.

It may be more effective to evenly distribute it, however, if it is not evenly distributed on the leaves is it still used by the plant?  

The suggestion is yes. It doesn't necessarily need to be even for the plant to absorb UGF 6-in-1 liquid fertiliser, which is the most crucial factor

Is there any downside to using a wetting agent or surfactant?

Although there may not be any major disadvantages, it's important to consider that if the plant has a waxy coating, using such a chemical could potentially cause some breakdown of the coating. It's possible that the natural integrity of the plant is temporarily altered to facilitate the absorption of the foliar spray by the leaf.

What is the best way to use UGF as a foliar spray?

Most people that apply it as a foliar spray simply mix 1:100 or 1:200 and do it semi regularly (this could be weekly or fortnightly or there about). Watch below how Award winning Australian Gardener of the year - Charlie Smith applies UGF as a foliar...



We suggest you leave it on the leaf (as long as its not a really hot day in direct sunlight) giving a better chance of absorption. If it is going to be hot day in direct sunlight, then we suggest you could put it on overnight, with a view to give it a light watering the morning after. This will let it disperse so you don't have fish oil sitting on the foliage.

All in all, it’s a case of horses for courses and we encourage people to do different split tests to judge more effectively what works for you and your garden.
