As qualified tree climbing arborists, our surgeons are always mindful to identify any poor structural conditions in a tree that will compromise the tree’s structural integrity and safety.
Our tree surgeons will use precise pruning techniques to remove any condition/s of weakness from trees, making the final cut back to the branch collar where the tree will be best able to compartmentalise to prevent the entry of decay or the establishment of dangerous epicormic regrowth.
Our tree surgery does not make use of chemical insecticides or pesticides, as they are not often practical to apply on residential properties and there effects are often short lived.
We encourage the good health of a tree to be it’s best line of defence. As the health of trees starts from the ground, we encourage the use of mulch, compost and organic fertilisers to improve the soil environment and tree health.
Tree Surgery for Mangoes
Mango trees on the Gold Coast are prone the diseases of Anthracnose and Bacterial Black Spot. These fungal & bacterial diseases will first establish on the old leaves where the leaf canopy if thick and aeration is poor. These diseases will often spread to the ripening fruit.
Symptoms on leaves- spots form commonly towards the margins, tan to dark brown in colour, often with a darker border.
Symptoms on fruits– slightly depressed grey black areas in the skin on ripening fruit, often rendering the fruit inedible.
Bacterial Black Spot
Symptoms on the leaves– black raised spotsthat tend to be angular in shape as they are limited by the larger veins.
Symptoms on fruits– black scabby spots are formed and open with star shaped cracks with water soaked margins, rendering the fruit inedible.
Chemical Control–In orchards the diseases are often managed with the frequent spraying of Mancozeb from flowering to harvest and Copper Oxychloride from flowering to fruit set.
As the frequent spraying on a residential property is impractical for many reasons, the tree surgeons of Your Branch Manager approaches the control of these diseases in a more holistic way.
Selective pruning controls Disease in Mangos
When left unpruned, the dense canopy of a mango tree will be prone to a bacterial & a fungal disease that establishes on the leaves & fruit. To control the diseases the tree surgeons of Your Branch Manager will remove some the taller upper canopy and will provide a suitable canopy thinning. With the improved aeration & light penetration, the opportunity for disease establishment has become less favourable and the incidence of anthracnose and bacterial black spot will decline.
The added benefits of this pruning method, is improved flowering and fruit set throughout the lower canopy of the tree, where the fruits can be more easily picked.
