Tools
Decide with numbers, not guesses
Simple calculators built on rules of thumb we use in the nursery. Every one shows its assumptions, so you can argue with them.
Tree finder
Filter every plant we grow by USDA zone, mature size, sun, soil moisture and what you want it to do: flowers, fall color, honey, fruit, wildlife, evergreen.
Open the finder →
Watering calculator
Gallons per week for a newly planted tree, from trunk caliper, weeks since planting and the rain that fell, with a schedule for the establishment phase you are in.

Growth estimator
A height and trunk-diameter projection by species, site quality and years ahead, shown as a poor-to-good range with a year-by-year table.

Tools we are building next
Planting-site check for a species
Enter a species and your site conditions and get a plain verdict on whether it will thrive, struggle or fail there.
Companion species
Pick one tree and see the natives that grow with it in the wild and in the yard.
Fertilizer rate
Whether a tree needs feeding at all, and if so how much of what, from soil, age and symptoms.
