Rain? What a novel concept. We're watering every day - I say we, my lovely wife is watering every day for me whether they need it or not!
The only thing I change is the duration. In the spring it's 2 minutes; now it's 3 minutes; and it will be 4 minutes during the high heat months.Except for rainy days, my automatic watering comes on TWICE a day at 10 am and 3 pm. I have 10 zones of watering and each zone receives 3 minutes of watering each watering.
It all depends on your trees. A larger tree in a bigger pot needs to be watered less frequently than a shohin in a small pot. Also, trees that have recently been repotted will require less water than a tree that is almost root-bound. Deciduous trees will often require wetter soil conditions than conifers... and the list goes on. I find it easiest to use broadcast sprinklers with a WiFi timer and group trees based on water needs. That way, if (for example) you need to water your Japanese maples, while you want to avoid watering your Japanese black pines, you have different "zones" that will receive different levels of water.Should I have my wife water in the morning also on weekdays.
It's been mid to high 90's with dew points upper 70's to low 80's the last few days here in SE MI... breezy, too. I've been watering twice daily, but I'm checking themI know this subject haunts us beginners and probably irritates the pros. I got my trees late in the year last year and the heat was gone. My area of the county is having a brief shower here and there (1/4 to maybe 1/2 inch) with heat of 100 degrees Fahrenheit with feel like 105 or so, Zone 8b Georgia. The humidity stays very high around here and I know I need to account for that also.
I am watering in the morning and evenings on weekends. Should I have my wife water in the morning also on weekdays.
I'm slowly getting to 3 times a day on some deciduous... later this week 35+ celcius... don't want to think what August will bring here in Shanghai...This time of year, I'm more likely to be watering TWICE a day, as the new foliage is rapidly extending, and the weather here in SE MI tends to be windy and warm, with LOW humidity, which vastly increases water loss through the foliage and soil surface. Once the foliage hardens off, and the summertime humidity arrives, once a day will be the rule.
You can tip large flat pots up on one side with a block of wood to help them drain faster when you have heavy rain.I think I don't water fully or something.The first 2 days of long rain I looked at everything in the morning and it is still stopping wet, not needing water the next day at all. I never had things looking like that the day after I watered.
After 2 weeks of substantial rain I had a couple things ROTTING! But it is better than dried out : )
