The Fund is dedicated to planting trees, providing education on the care of trees, and the on-going beautification of our community.
Over a 50-year lifetime, a tree generates $31,250 worth of oxygen, provides $62,000 worth of air pollution control, recycles $37,500 worth of water, and controls $31,250 worth of soil erosion. (USDA Forest Service Pamphlet #R1-92-100) Total: $162,000 — quite a return on a $750 investment!
We have a downloadable brochure (in PDF format) that has all the information you need on ordering, planting, and caring for your tree. You may view our brochure here. You may also contact us via email or telephone — please see our Contact Us page.
Important Information about Watering our Street Trees
A Cobble Hill Tree Fund member passed on the note and information below, sent out by our Boerum Hill neighbor, Margaret Cusack, of the Hoyt Street Association. It contains very useful reminders and important information regarding care of our street street trees during the hot weather. — CHTF
With all the hot weather that we are having, many of the street trees are stressed because they are not watered regularly. Please read the info below (provided by the NYC Dept of Parks & Recreation) and take an interest in the street tree nearest your home. (You might even consider adopting more than one tree.) Keeping containers of water near your front door will remind you to take care of your tree. Thanks.

CARING FOR STREET TREES
- Water each young tree 15-20 gallons once a week between May and October (that’s 3-4 large buckets).
- Using a hand cultivator, loosen the top 2-3 inches of soil to alleviate compaction and help the water and air reach the roots.
- Water slowly so the water penetrates the soil and does not run off of the surface.
- Water at the soil level, not the leaves of shrubs and groundcovers.
- If it rains 1 inch or more in a week's time period, you do not need to water.
Watering is the most important thing you can do for your street tree. It may also be the most difficult task to accomplish. Transporting water from the source to the tree is a challenge. Furthermore, because of compaction and pollution, urban soil is hydrophobic and difficult to penetrate. This means that you need to cultivate or loosen the soil so that the water can reach the tree's roots. There are a number of different tools and techniques available to aid your watering efforts.
- Poke small holes at the bottom of a large trash-can. Fill it with 15-20 gallons of water and leave the trash can next to the tree overnight.
- Ask building maintenance staff to water trees while they are hosing off sidewalks.
- Ask street vendors and merchants to dump water from their containers (coolers with melted ice or flower buckets) into nearby tree pits at the end of the day. Make sure water with detergent or bleach is dumped into the gutter, not the tree pit.
- Apply a three-inch layer of mulch, preferably shredded bark, to the tree pit. Mulch keeps the water from evaporating quickly, reduces soil compaction, and improves the soil as it breaks down. Do not pile the mulch against the trunk of the tree or shrub; water will accumulate and rot the trunk.
- Prevent dogs from peeing and pooping in the tree pits.
- Remove weeds and debris from the tree pits.
