Hello everyone,

Last year, we purchased a plot of land in North Rhine-Westphalia.

On the property, we have two cherry trees, one apple tree, and one pear tree. All the trees bear fruit and, according to the previous owner, are approximately 15 to 20 years old.

Since it hasn’t rained for weeks, we are concerned that the cherry harvest might be smaller than usual. The cherry trees are blooming, but the fruit development has only just started.

Should we provide artificial irrigation, or do the trees draw enough water from the soil? According to our neighbors, who all have wells, the groundwater level is currently about 5 to 6 meters (16 to 20 feet) below the surface.

Old trees should be able to survive a dry period, but it won’t hurt if you water them a little. You could ask your neighbors with a well if you can take a few hundred liters (a few hundred gallons) in exchange for a small payment or a beer.
It’s supposed to rain next week, so the situation should improve.

It's really surprising that the 8,000-liter (2,113-gallon) cistern has been empty for over a week already. And this in April.

The cherries are flowering, but does growth only really start now?

When it comes to the blossoms, the tree would conserve resources first. I watched a film yesterday with forester Wohlleben, who warned against watering trees artificially: this prevents them from extending their roots deeper as a form of self-help. In other words, they can help themselves, and if you intervene, it can actually harm them the following year—it’s better to let them activate their own natural coping mechanisms. From a forester’s point of view, a tree of this age is still quite inexperienced.

Regular watering of trees should always be done through deep root irrigation. Otherwise, the tree's roots will not grow deeper.
Occasional surface watering does not cause much harm. If the dryness becomes severe or urgent, build a watering ring around the tree and allow a few hundred liters (several dozen gallons) of water to soak in.

I have watered my trees for the first time now. They have already been under a lot of stress over the past few years. However, I am not doing this regularly; it was an emergency measure. Trees also need a lot of water since their roots are relatively deep. Surface watering doesn’t help much anyway. If it doesn’t rain in the coming period, I will repeat this once a month. I slowly applied about 300 liters (80 gallons) of water, distributed over two spots a few meters away from the tree. I have no idea if this is the correct method. But I hope that, in this way, the water slowly seeps down to the surrounding roots.
