The Colorado Front Range is naturally a semi-arid, shortgrass prairie that would have few trees without irrigation. Growing trees here is difficult in wet years, not to mention the challenges in drought years. Properly placed and maintained trees are an asset to the environment and to our community.
Growing Season Watering Tips (April- October)
Remember - Winter watering in Colorado is very important!
During the winter, some root development may occur, especially for newly planted trees. Without water they may dehydrate and die before spring. Winter watering can help save your trees.
Winter Watering Tips (October through March)
Maintain wood mulch around the base of the tree throughout its lifetime to increase growth and optimize tree benefits. Mulch plays an important role in regulating soil temperature, maintaining soil moisture, and serves as a barrier to potential damage from string trimmers and mowers.
Mulch is available free to Boulder residents from Western Disposal. You will see the sign for the city mulch pile when driving east on Pearl Parkway between 49th and 55th St.
We may have staked your public street tree when it was planted.
Some trees need staking to provide stability for the roots. If your new public street tree was staked, we will remove the stakes after one year.
Support stakes can do more harm than good when left too long. Stakes restrict movement which reduces natural growth processes and causes the tree to be less able to bend with the wind.
Wrap your tree seasonally to prevent sunscald. Most young, thin barked trees are susceptible to sunscald. Sunscald occurs in winter months during a warm day when temperatures may be high enough to activate cells and tissues beneath the bark. These activated cells freeze at night or when temperatures drop. The frozen cells shrink and die, leaving elongated, sunken sections of dead or cracked bark.
After few years, tree wrap is not necessary in the winter months. As trees mature, their bark will thicken, providing natural insulation and protection to underlying tissues.
Tree Wrap Tips
Keep the mowers and weed whips away!
Before beginning work on your property, consider the possible impacts to trees in the public Right of Way or on your own property.
Most tree roots are in the top 6'- 18' of the soil and extend out beyond the canopy (dripline). Construction and landscape installation within the root zone can seriously damage your trees. Trees that suffer severe root damage may not show symptoms for several years. The damage is not reversable, but it is preventable.
In addition, damage to the bark and the underlying tissues can seriously injure the tree. It is important to be aware of how your landscape practices can help or harm trees.
