Tree and shrub care

It is best to water deeply and slowly, which will allow the water to reach deeper roots and be retained by the soil longer.

 

watering

Water freshly planted trees and shrubs thoroughly to give them a good start. Thereafter water when the soil surface dries out. It is best to water deeply and slowly, which will allow the water to reach deeper roots and be retained by the soil longer. Using a soaker hose around the base of trees and shrubs is usually the most effective way to ensure deep, thorough watering. Do not rely on rain to water your trees and shrubs sufficiently. It is important to observe the condition of your trees and shrubs often to ensure continued healthy.

 

All trees should be well watered in the fall as a routine practice, with special attention to those showing any drought symptoms.

 

 

post-planting care

For the first season newly planted trees and shrubs should fertilized using a fertilizer with a high phosphorous content, with is the middle number, we recommend 10-52-10, which stimulates root growth.

 

Note: If Myke has been used when planting the tree or shrub, Myke’s fertilizer must also be used since its low ratio of elements will not inhibit Myke’s production of root extensions (filaments) provided by mycorrhizae. Trees and shrubs planted using Myke carry an extra 5 year warranty if the terms and conditions of the Myke Tree and Shrub Warranty are followed.

 

For established plants you can fertilize deciduous trees and shrubs every two to three weeks, until August 15, with an all-purpose, water soluble fertilizer such as a 20-20-20. For evergreens a 30-10-10 ratio applied in 3 times during the growing season, in May, June and July, is recommended.

 

 

maintenance

Routine feeding and watering will generally be enough to satisfy the nutritional needs of trees and shrubs through their growing season.

 

Water trees and shrubs in well by the end of October. Ensure that your plants root-ball is completely saturated by performing a slow, thorough watering.

 

Trees and shrubs may be pruned back and mulched for extra protection in the fall. This mulch should be removed in the spring. Dead foliage should be pruned away in the spring.





Birch Tree

Birch Leafminer Larvae


Birch Leaf Miner Larvae

When saving your Birch Tree timing is the Key!

In the past, we have been able to purchase a number of different controls for the pest known as Birch Leafminer. Today there are very few, however, nematodes have been found to be very effective at controlling the larvae before they emerge from the ground and now is the time to act.

Birch Leaf Miner Larvae

If you have seen or have had Birch Leafminer in the past, then you know that the damage is unsightly and not really great for the overall health of the tree infected. However, tree death has not been implicated from Birch Leafminer. Damage appears as a small brown or reddish-brown, irregular-shaped patch on the upper surface of the leaf. It actually looks much like a mine through the centre of the leaf. If the mine is occupied, the pupa can be seen when the leaf is held up to a light. The issue is that the pest once inside the leaf is protected from topical treatments.

Leaves that are attacked by Birch Leafminer larvae will often appear curled at the edges. The Leafminer attacks before the leaves have fully expanded, which interferes with normal development and results in a deformed leaf. This is why introducing nematodes into the soil before the tree leafs-out is important! To control the pupa while they are in the soil is most important. Once they are in the leaves or are at large as an adult the nematodes are ineffective! The pupa are now coming out of cocoons where they overwintered from last year. The female will move up the tree depositing eggs that hatch and feed on the leaves before emerging as an adult. Birch Leafminer nematodes attack the pupa in the ground and interrupt their life cycle before they can do damage to the trees. Nematodes are basically microscopic worms that move through the soil by water channels between the soil structure. It's important to apply nematodes at the right time and temperature. Plus 10 degrees is required. Nematodes are applied by mixing them in water or a dispenser designed specifically for the application. Water with the nematodes around the tree's drip line and that's about it. Once the nematodes are in the soil water again in a couple of days, this will help them move about and track down their prey.

You will find the nematodes in the fridge here at greengate Garden Centres and just a tip: keep them refrigerated until use.
