Drought is killing Colorado trees, either directly through lack of water, or by causing such stress that insects and parasites are able to cause problems.
We’ve got a bit of drought scorch on one of our new maples. I need to get out there and do some deep watering around all the trees.
If you have the $, buy a few of those 20 gallon soaker bags – you fill them and they drip irrigate the tree slowly, so it has a chance to pick up more water, and uses less water than your deep soak.
I imagine if you have a few five gallon pickle buckets (I pick these up free at the Festival, if you’re brave, you can ask if they will give you one at a fast food place) and put a few small pinholes in the bottom, you can get the same effect…
(I use my pickle buckets as rain barrels, to catch the runoff from my roof… not very efficient(sp?), but it’s something!)
Hmmmm. Soaker bags …
