Managing Trunk Injection Work in Your PHC Program

Trunk injection is its own kind of PHC work. It is slower per tree than a foliar round, it often depends on tree size, and some injection programs run on multi-year cycles instead of every season. It is also some of the highest-value work in a PHC program, especially when a property has large, valuable trees under pressure from a serious pest. Managing it well means getting the schedule, the records and the price right.

Why Injections Need Their Own Planning

Scheduling Recurring PHC Treatment Programs Without Losing a Round covered recurring rounds in general. Injections deserve their own look because they behave differently from spray and soil rounds. Time on site depends heavily on tree count and size, product amounts often scale with trunk diameter, and cycles may run longer than a year.

If you treat injections like just another round, you end up under-booking the day, under-pricing the job, or losing track of which trees are due this year.

Using DBH and Tree Counts on the Property

TreeBossPro property records hold the number of trees, trunk diameter (DBH, in inches) and tree height in feet, plus custom fields and tags. For injection work, DBH is the field that matters most, because many injection products determine dose by trunk diameter, according to their labels.

Measure and record DBH during the consult or the first visit. Note which trees are enrolled in the injection program in the crew notes or a custom field. When the injection round comes up, the applicator knows exactly which trees and how big, before they arrive.

Injection days also tend to run long when the crew discovers more enrolled trees than expected or trees larger than recorded. Accurate property data is what keeps those days on schedule, which is why the first visit is the time to get it right.

Scheduling Multi-Year Cycles

Some injection programs repeat every year; others run on longer intervals, depending on the product and the situation. Set up the injection round as its own recurring job at whatever interval your program uses. That way an injection that comes back in two years is still in the system when it comes due, instead of depending on someone remembering.

Keep injection rounds separate from the rest of the property's PHC rounds so you can schedule them on days and crews suited to the work.

Trees grow, so DBH recorded five years ago may understate the tree today. Re-measure enrolled trees periodically, especially fast-growing species, and update the property record. The price and the product amount both depend on it.

Recording Each Injection

Injection applications deserve the same records as any other application: product with its EPA registration number, rate, amount used, and the applicator with their license number. The per-service application record captures product, rate and amount, tied to the property and date. Note which trees were treated in the job notes.

Photos from the crew app are useful here, for example showing the tree before treatment or the injection sites. Always follow the product label for dose, timing and method; your record documents what was done.

Keep a clear note on each property about which year the injection cycle started, especially if cycles differ between trees on the same property. A customer who added a second tree to the program two years after the first may have trees on different cycles, and the schedule needs to reflect that.

Pricing Injection Work

Because injection effort and product often scale with trunk size, many companies price by DBH or by tree. The tree count and DBH on the property record make that straightforward when building an estimate. Estimates go out with online approval and automatic follow-up for customers who do not respond.

Make sure the price covers product cost, time on site and travel. The amount used on past application records helps you check whether your pricing assumptions held.

Explain injection pricing clearly on the estimate. Customers understand that a large tree costs more than a small one when the reasoning is visible. Listing the enrolled trees with their sizes, rather than a single lump sum, makes the price easier to accept and easier to renew.

Selling Injections Inside the Program

Injections often come up during a consult or a pruning visit, when a crew member notices a valuable tree under stress. Capture that observation as a lead or an estimate on the spot. Recurring injection work that renews on its cycle is exactly the kind of revenue PHC programs are built on.
