Before planting a tree: build a plan with local guidance
Gather useful site information, find reliable local advice and decide how a tree will be cared for before choosing one.
Describe the place before choosing the tree
Write down what you want a tree to do: provide shade, mark a family occasion, add seasonal interest or contribute to a larger garden plan. Then sketch the possible location with nearby buildings, paths, existing plants and visible overhead lines. Add approximate dimensions and photographs taken from more than one direction.
The Arbor Day Foundation’s planning guide identifies mature height and canopy spread, soil, sunlight, moisture and hardiness among the factors to consider. Use that as a list of questions to investigate. The size of a young tree in a container tells you little about the space its mature crown will need.
Notice what you can without digging: which parts of the site receive sun, where water seems to linger after rain, and how the space is used. Mark uncertain observations as questions instead of filling the gaps with guesses.
Find an adviser who knows your area
Your state’s university Extension service is a useful starting point for research-based local gardening information. The USDA’s land-grant university directory can help you find the institution, then its Extension pages and local contacts. Municipal forestry staff may also provide guidance about public trees and street-side planting.
Bring your sketch, photographs and goals. Ask which locally appropriate species suit the site, which invasive or problem species to avoid, whether soil testing would help and what season is suitable for the particular tree stock. Request a local planting and establishment-care guide you can refer to later.
State-specific advice needs its geographic context. For example, University of Maryland Extension’s planting guide discusses sunlight, mature size and drainage alongside regional recommendations. Use it to understand the kinds of issues that matter, then find the guidance for where you actually live.
Resolve permissions and utilities early
Confirm who owns and controls the proposed site before buying a tree. A verge beside a sidewalk, a shared courtyard or rented property may need approval from someone other than the person volunteering to plant. Ask the relevant owner or local authority about the location and any applicable planting requirements.
In the United States, use the official 811 before-you-dig service before digging. Follow the instructions for your state, including the required notice, responses and marking process. Ask about privately owned lines that may require separate locating. Do not treat a surface inspection or an assumed shallow hole as a substitute for that process.
Include the utility information when confirming a site with your adviser. A tree needs room as it grows, and the final placement should account for overhead as well as underground services. This is a planning step to finish before a planting-day invitation goes out.
Write down who does what after planting
Before committing, name the person responsible for ongoing care and a backup when that person is away. Ask your local adviser for a watering and inspection plan suited to the tree, site, weather and available water. Record where the instructions will be kept and how you will note completed care.
Keep a simple tree record: species and cultivar if known, planting location, planting date, supplier information, local care guidance and a starting photograph. If a problem appears later, those details make it easier to ask a useful question.
If the site or care plan is not ready, Arbor Day can be the day you finish the research. Attend a demonstration, visit mature examples of a candidate species or bring your questions to Extension. A well-considered decision is a useful result of the holiday, even when the planting happens another day.
