what I learned about watering young trees
This will probably seem obvious to the farmers out there ....
Was talking to the guy that farms some of my acres this weekend while he was harvesting corn. It was a dry year here but good enough to get a decent corn crop if you got it in early.
Farmer mentioned that he could easily tell the sandy soil areas by the lower yield and shorter corn stalks. He mentioned in a normal year of rain there is no difference.
I had a couple other indicators that maybe my watering was inadequate and this kinda finalizes it.
If your soil is sandy you need to water a lot more even with mulch. I was watering new planting once weekly for the 1st year and now believe sandy soil requires more frequent watering for optimum growth. Ditto for a really dry year like this past one. (I also discovered trees in sandy soil can need additional nitrogen as it washes out of the sandy soil relatively quickly. thx to harvestman for that diagnosis.)
hopefully this will be helpful to someone else.
one of the fun things about growing these trees is you are learning something new constantly.
