For example, we get calls from customers who want to use their existing sprayer and simply purchase a new spray gun to spray to further heights.  Unfortunately, this is not how it works: the whole system needs to be adequate.  If you don’t use the right tank, pump, spray hose or spray gun you won’t hit the desired distance.  

Here are 3 important things to consider when spraying tall trees: 

1. Pick the right tank size - It's necessary for the tank capacity to be 5 - 6 times the max flow rate of the pump. We recommend the largest tank possible while still fitting space requirements. One of the main issues with using a tank that's too small is that the high flow rate of most pumps will empty a small tank quickly and create cavitation in the lines which leads to decreased performance. 
2. Pick the right pump, spray hose, and spray gun - In order to proper height when spraying tall trees, both flow and pressure are required. So a spray hose with with a diameter large enough that it does not restrict  the flow of the liquid is essential. High pressure will atomize the droplets and allow them to reach increased heights. 
3. Wear appropriate personal protective equipment (PPE) - PPE protects the body from  hazardous chemicals. To reduce the risk of harm or injury, professional spray applicators should wear face, eye, skin, and hand protection.
