“My Tree Is Out Of Control!”

A Niwaki customer gave our arborist a call and said their maple tree was growing way too large for its space. The tree provides great shade from the setting sun, but if left alone, will overgrow the space and need removal.

A trench has been made around the flare of the tree and is ready for the tree growth regulator application.

Niwaki has the solution to this common problem. We can treat the tree with a tree growth regulator and slow the tree’s growth up to 70% its normal growth rate. This treatment is very affordable and only needs to be performed every three years. If

Tree growth regulator solution is evenly applied within the trench and will be drawn into the tree through normal respiration.

you have a tree or large shrub that is getting out of hand call Niwaki at 704-980-9516. Our ISA Certified Arborists will evaluate your tree to see if its a good candidate for this service.

 

Self Defense

OLYMPUS DIGITAL CAMERADid you know that certain types of trees warn each other when they’re being attacked by insects?

It has been found that Willow and Poplar Trees produce an excess of chemicals to not only reduce the nutritional value of their leaves for the insects, but also warn neighboring trees. Following the warning, nearby trees will begin to produce the same chemicals, defending themselves from similar attack.

Why we have Fall color…

Do you know What Produces the Different Colors in Tree Leaves?


Yellow Pigments = Carotenoids

Carotenoids are pigments that have been present in the leaf cells all the time during the leaf’s life. They provide the yellow that leaves exhibit when the chlorophyll is not present.

Red or Purple Pigments = Anthocyanins

Anthocyanins are pigments that form in the cell sap of some species in the summer and fall. The combination of dwindling chlorophyll and resulting sugar breakdown, along with bright sunlight, cool temperatures, and transfer of phosphorus from the leaf to the steams, produce the red and purple anthocyanin pigments seen in maples and other species.

Orange Pigments = Carotenoid’s and Anthocyanin’s

It is the combination of the two pigments that bring out orange colors in trees.

Green Pigments = Chlorophyll

During the spring and summer, the green chlorophyll pigments dominate and mask out other pigments in the leaf.

Brown Pigments = Tannin

Tannin’s cause the brown hues often seen in tree like oaks. Tannin’s actually act as a defense system for plants against pathogens, herbivores and poor environmental conditions.
