Another nice video. I'm a fan of your new youtube videos.
I tried your old once a week deep watering schedule here in Tucson, but
had to immediately give it up. My trees, especially VdB, didn't like it. They
prefer at least twice a week, three times a week during hot spells. One new
observation I've seen with VdB is that the droopy, thirsty looking leaves it
has during hot spells is from the leaves themselves. I happened to graft a limb
of Col de Dame noir onto my in ground VdB. The leaves on the Col de Dame don't
droop like the VdB leaves do in the heat. I think maybe the drooping leaves aren't
necessarily a sign of underwatering if the CdD shows no sign of water stress fed
from the same roots. Its a bit funny looking to see the VdB drooping with the
one CdD limb leaves all upright.
I'm interested in your list of favorites. I have three of the four and agree with
your rating of DK, BM and VdB. I have had good results from Panachee here as
well in a nearly identical climate.
I hope you have lots of video material again this year into the fall.
