What we do at each treatment, how it differs from spraying the whole tree and the best time to treat.
During the free visit we look at the tree: its species, size, condition and the pest or problem affecting it.
We choose a product authorised for that use and adjust the dose to the tree.
Using dedicated endotherapy equipment, we inject the product into the trunk. The sap carries it throughout the tree.
We explain what to expect and when the treatment should be repeated, so your tree stays protected.
In a garden with a pool, a terrace, children or dogs, you'll notice the difference.
| Endotherapy | Spraying the whole tree | |
|---|---|---|
| Where the product goes | Inside the tree | Onto the crown and everything around it |
| Wind | No effect | The product can drift onto terraces, pools or your neighbours |
| People and pets | Minimal exposure | More exposure during and after treatment |
| Rain | Doesn't wash the product off | Can reduce the effect |
| Public and urban areas | The recommended method; some palm products are only authorised this way | More restrictions |
On palms, we combine endotherapy with foliar spray aimed at the crown, so we also kill the adult beetles on the outside.
The treatment itself is always the same. When we treat depends on what's affecting your tree.
| Problem | Trees | When we treat |
|---|---|---|
| Red palm weevil | Palms | Prevention with three treatments a year: endotherapy plus foliar spray in spring and autumn, and foliar spray only in summer. |
| Pine processionary | Pines and cedars | Once a year, in October and November, while the caterpillars are still small. |
| Fungi and chlorosis | Various trees | After the inspection, depending on the tree and the season. |
No. Only authorised products may be used, and treatments must be carried out by staff with an applicator's licence. Endotherapy also takes the right equipment and experience to avoid damaging the tree.
Mainly pines and cedars against pine processionary, and palms against red palm weevil. We also treat trees with fungal diseases or chlorosis. During the free visit we'll tell you whether endotherapy is the best option for your situation.
