Shrub Spray Program – How it Works

Shrub Spray Program – How it Works

On Long Island, there are two things attacking your trees and shrubs; insects and fungus. Pests and fungus can take over your garden quickly and negatively affect the investment you made in your landscaping.

The good news is there is a way to battle back.


Old Mill’s Shrub Spray Program

Old Mill’s Shrub Spray program helps eliminate the insects and fungus that destroy your trees and shrubs.

If you suspect there is an issue with your trees, like leaves of your trees turning brown in the middle of the season, our team will come visit you and determine what is attacking your plants.

Once we determine the insect or fungus attacking your trees and shrubs, we prescribe an insecticidal or fungicidal treatment that will make your plants healthier, eliminating what is ailing them.


Timing is Everything

Our technique, timing, and type of spray we apply to your plants depends on what is being treated.

Some pests and fungi require that we apply a series of sprays for control. When multiple applications are necessary, timing is critical.

For your plants to receive the best treatment, we apply our spray according to the life cycle of the pest/fungus to be controlled.  This approach yields the best results.


How to determine if your Plants are under Attack

There are a lot of pests out there that can destroy your plants. Here’s four common problems our customers have:

Leaf Miner:

Leaf Miner is a name for insects when they are in their larvae stage. Two of the most “popular” insects that we see on Long Island are moths and flies.  These insects attack various kinds of shrubs and bushes but lately we have seen a lot of damage to our customers’ Arborvitaes.

Leaf miners go through complete life cycle from egg and larva to pupa (cocoon) and adult. Adults lay their eggs on the leaf’s surface and the larvae burrow into the leaf and eat the plant tissue from inside the leaf.

The burrowing larvae leave a meandering trail on a leaf or turn arborvitae tips brown.


Spider Mites:

Spider mites are technically not insects, but are classified as a type of arachnid; a relative of spiders. Spider Mites live in colonies, and are typically found on the underside of leaves. They feed by piercing leaf tissue and sucking up the plant fluids. The piercing and feeding marks look like light dots on the leaves.

As spider mites continue to feed, leaves turn yellow and may dry up and drop off.



Scale looks more like a plant disease, but scale are actually tiny insects. They adhere to plants in colonies and feed off the plant’s sap.

As scale continue to feed, leaves turn yellow and branches begin to die.



Most fungus attacking Long Island trees looks very similar to a mushroom. Fungi can grow on the trunk or roots of a tree. Fungi attack the interior of a tree and can weaken or even kill the tree.

Whenever you see “mushroom-like” structures around or on your tree, most likely it’s due to a fungal infection.
