[CANUFNET] TreeAzin, drought and deep-root watering?

[Shields, Peter]

I don't have data but can tell you that watering the tree (slow hose trickle, spray trench or deep root injection) will help with the uptake and only ensure the product moves. I am sure the trees will benefit from the watering regardless. The fertilizing is another issue and would avoid fertilizing until into September given the lack of water.  The cheapest way to do this will depend on where the trees are. Are they Municipal trees, private, back yards...letting homeowners know in some way often will get the trees looked after at little to no cost.

Does anyone know if deep-root watering will enable TreeAzin to be effective after the drought we're having in Ottawa, in case we don't get enough rain between now and the closing of the TreeAzin-effective window (end of August)?  There is a risk that we may miss the window if we don't get enough rain in the next few weeks. It would be helpful to know if anyone has any experience or seen any research on whether a deep root watering/fertilizing would be enough to make the TreeAzin injection effective in the absence of some good, long rainy days.
