"Welcome to Urban Forestry on ChangeX! We want to inspire and empower you to increase the trees in your neighborhood. Trees provide so many benefits for our communities and appropriate tree species and placement can maximize those benefits and minimize maintenance efforts. Share the benefits of trees with your community, find out here how to find a place and organize a tree planting. " - Aubrey Coffey-Urban, Arizona Sustainability Alliance
You'll need 2-3 hours each week to get your team together, to create a project plan, to reach an agreement with your property owner and to plan your planting day. Your planting day will be one full day (in early fall).
Planting trees is an opportunity to engage with lots of people in your neighborhood and getting a strong team onboard from the outset will be critical to your success. One of the most important parts of your 30 Day Challenge is building your team and getting them together to kick-start this project. These are just some things to keep in mind as you get your team together:
Your organizing team will ideally include:
You'll need approximately 1.5-2 volunteers per tree for the day of the planting. You don't need to have all of these on board from the initial planning stages but keep in mind where and how you might recruit these volunteers as you plan and get your initial organizing team together.
Once you have your organizing team together, you'll need to decide on the goals of your tree planting project - discuss with your team why you are interested in doing this planting and decide on what you want to accomplish, or what you want to improve in your neighborhood.
One of the most critical considerations in undertaking this project is the planting location - based on the purposes of the planting, determine where to look for a planting location and set out some requirements as to how it will be selected. For example, if you want to increase walkability, you will want to look for areas where there is room for trees that could help cool/shade a walkway/street. If you want to increase trees in parks, you will need to look for parks in your area that have room to plant additional trees. If you want to increase tree canopy overall, you may want to look at a tree shade map (see below).
An important part of choosing a suitable location is getting to know / working along with the property owner. Maybe you already have a location & property owner in mind? What do they think of your project and what concerns or challenges do they have that affect the project? What are the needs of the property and how do they intersect with your goals?
Does your City have an urban forestry master plan that your planting might further and align with?
Here are some examples of Forestry Plans in Arizona:
This is a good resource for information about desert-adapted trees that are good choices for the Phoenix metro area. It includes information on naming and quantifying the community benefits of those trees. The info in this report can be used outside of Tempe, but it’s also a good idea to see if your city has a similar master plan with even more customized information. This can help you wrap your private planting into the City’s broader goals.

At this stage, it's also good to do some research into where you might source tools and trees locally. Often, you can borrow tools from a tool library or tool bank, this eliminates waste associated with buying tools if you don't plant to use them again in the future or do some research on local nurseries where you can purchase your trees.
Some things to consider to reach agreement with your Property Owner
An Arborist or a tree consultant can help you choose suitable tree specimens from your local nursery and also advise you on planting locations
You should decide where you will source your trees and make sure tree expert can go to pick out the specimens at least 1 month in advance. Don’t forget to ask about delivery cost and timing options
Once you've made a decision on the size of trees you can decide whether holes will be pre-dug and which tools will be needed (don’t forget a caliche or digging bar) - these are both important decisions for your Planting Day plan!
Your planting day will be a fun day out for all of your team and you'll finally get to see all your hard work in planning and research pay off!
Typically the responsibility for ongoing maintenance would lie with the property owner so make sure this is something you discuss as part of your agreement
Watering Advice
The information below is for desert-adapted trees. This means trees like palo verde, palo blancos, acacias, eucalyptus, and desert willows. If you are planting a new tree, the amount of water it takes will vary as it grows and what season it is. See the below table for estimates of how much to water a tree, so that it is watered to a depth of about 3 feet, based on its canopy size. We take a few of these numbers to create estimates for how much water the tree will need to be watered as it increases in size. It takes 2-3 years for trees to become established.
Newly planted:
Week 1: 1-2 days per week (summer) 3-4 days per week (winter)
Week 7: water every 7 days (summer) 10-14 days (winter)
After 8 weeks gradually increase the amount of days in between waterings until established
Below is an estimate for how many days the trees need to be watered once established. This is a high estimate, as some of these trees may need no water at all in certain years.
Established trees March - May: 14-30 days May - October: 7-10 days October - December: 14-30 days December - March: 30-60 days You can find much more detailed information from:
