Boulder Tree Care is commented to providing the highest quality of tree service and plant health care.

In the early planning stages, long before you begin a new construction project, contact us and we’ll help you create tree protection zones. We will establish and secure a perimeter around your trees large enough to protect the root structure and create for you a set of written instructions you can hand to the foreman so he understands the proper procedures necessary for preserving your trees. Perimeters in place, he can easily inform construction workers about the tree protection zones on your property.
If you or anyone you know has any questions about the health or safety of your trees due to construction contact us and we’ll have a look.

All the trees are in full bloom early this year and the plants and fruit trees are being pollinated by the wind, butterflies, bees and other insects.

So what happens when there is a cold snap?

Well, depending on how cold it gets, the temperature may determine how much fruit is produced this year.

When the trees and plants flower they produce nectar which attracts bees and other insect. Pollen clings to the insects gathering nectar and when they fly from flower to flower the stigma receives the pollen.

Once the plants are pollinated the petals will fall away and the stem that the flower was attached to will begin to swell, eventually producing a fruit. If the flowers bloom and then there is a sudden cold snap, the flowers fall away before the process of fertilization is complete.

This is one of the main reasons here in the Rocky Mountain region we rarely get apricots. Apricot trees are one of the first to bloom in the early spring.

Often, there is a cold snap that happens soon after those first really nice, warm days. This year is unusual in the way all the trees have already flowered in March, blossoms that we would not normally see until the middle of May are already blooming.

The photos above are from a crabapple tree in our backyard. You definitely want to check out what happened to those apples.

Wow! What an interesting call I got today.

The owner wants us to remove this tree house from an old cottonwood on his property. Look at this thing.

It’s wedged in there real tight from the wind opening and closing the branches and the tree house falling deeper and deeper in there.

The back half pulled of it’s support and fell down while the front is still anchor bolted on the other branches. They said the racoons moved in for a while before it completely fell apart.

Working out the details on the bid. Intense tree house removal job!

Super dangerous with all the tension and stress from the bolts, cabling, the house and the the tree. What do you think? How much would you charge to remove this beast?

Spring is here and you may want to prune back your trees before all their leaves fill out.
Your trees will be happy if we get that heavy, wet April snow.

By thinning the canopy the snow will not accumulate as much on the leaves and branches and they will be less likely to break.

Early spring and late fall is when we get most our emergency calls. Usually, in the spring, it’s because we get a late snow after leaves have already filled out and in the fall we often get an early snow before trees have had a chance to drop their leaves.

Spring is officially here and soon honey bees will begin to swarm. We catch bee swarms if you happen to see one! Here’s a picture of one we caught a couple years ago.

Just last week in April 2016 we were working on a tree down the street from our house when a bee hive on the property swarmed into an apple tree across the street. The swarm was captured and installed in another hive shorty after.
