Watering Afghan/Mondell Pines and Mediterranean Pines
How often should I be watering these two types of trees? I will be watering by hand, also how long should I water each. They have not been watered except rain in the last 2 years, and I think they maybe drying out. I also think most are about 25 years old some are about 10 I guess. I read that the Afghan/Mondell Pines do best in about 12 to 16 inches of rain, and the Mediterranean/Jerusalem Pines do best in about 20 inches of rain. That is 3 to 5 times higher than the average of 4.5 inches per year in Las Vegas, NV. So they obviously need some watering, the Southern Nevada Water Authority says they need low to moderate watering but does not say how much that is. Can someone Please Help?!
