Yard & Garden Printable

Tree and Shrub Care Log

A printable multi-year tracker for your trees and shrubs covering inventory (plant ID, species, location, planting year, current DBH, canopy width, target health), annual fertilization (date / tree ID / product / amount lb+kg / application zone / soil pH / cost USD+CAD), pruning, pest and disease, mulch and amendments, and multi-year DBH growth tracking. Quick reference card at the bottom covers target pH by species type, N rate per species, dripline ring math, when NOT to fertilize, and US Cooperative Extension + Canadian provincial labs.

Pair with the Tree and Shrub Fertilization Calculator for the math, the how to fertilize trees and shrubs guide for the practice, the Soil pH Testing Guide for the testing side, and the Soil Test and Amendment Tracker printable for soil-side tracking.

Frequently Asked Questions

Why log trees and shrubs separately from the lawn?

Three reasons. (1) Decision cycles differ: lawn fertilization is yearly with multiple applications; tree fertilization is often zero applications per year for healthy mature trees and 1 to 2 for younger or struggling trees. (2) Per-tree tracking matters: when one oak struggles and another thrives in the same yard, the log tells you which one got pH amendment, fertilizer, or mulch differently. Memory exaggerates. (3) DBH growth tracking is the early warning system for tree health: most trees add 0.5 to 1.5 inches of trunk diameter per year; consistently slower than that signals soil or pest issues worth investigating. A paper log takes 5 minutes per tree per year and pays back in better care decisions.

How often should I measure DBH?

Once a year, ideally at the same time (early spring or fall). Use a flexible tape at 4.5 ft (1.4 m) above ground. Measure circumference and divide by 3.14 if you do not have a diameter tape. Mark the trunk at the measurement height with a small dab of paint or a tied ribbon so subsequent years measure at the same spot. Year-over-year growth: most species add 0.5 to 1.5 inches of DBH per year; oaks and slow-growing conifers can be 0.3 to 0.7 inch; fast-growing maples and poplars can be 1.5 to 2.5 inches. A consistently slow grower or a tree that has stopped growing entirely needs investigation.

Where in Canada should I send a tree soil sample?

A&L Canada Laboratories (London, ON) handles tree-zone samples nationwide at CAD 45 to 65 per sample. ALS Canada has multiple labs across BC, AB, ON, QC for faster western turnaround. MAPAQ (Quebec public lab) tests in French or English at CAD 35 to 50. Provincial agronomy offices serve their own provinces: BC Ministry of Agriculture, Alberta Innovates, SK Soil Testing Lab, MB Agriculture, NS Soils Lab (Bible Hill), PEI Analytical Services, NB Agriculture. For US-side trees, state Cooperative Extension labs at any Land Grant University handle tree zone samples for free to USD 25. Sample 4 to 6 inches deep at the dripline ring; mix 5 to 8 sub-samples per tree zone.

What does year-over-year DBH growth tell me?

It is the simplest tree-health metric available to homeowners. Most established trees add 0.5 to 1.5 inches of trunk diameter per year under good conditions. A tree that adds 0.2 to 0.3 inches per year is stressed: drought, pest pressure, soil compaction, or fertilizer deficiency. A tree that has stopped growing entirely is declining and needs investigation. Compare year-over-year, not against neighbors (genetics, microclimate, and underplanting all vary). Track on the multi-year DBH section of this log; flag any year-over-year drop greater than 50 percent.
