How much water for rhododendron?

Posted by anitje 5b (My Page) on

1. Approx. how much water (in gallons) should I use in watering a rhododendron that is 4-5' tall? I planted it about 2 months ago (with a burlap-encased root ball) in partial shade, and was told to water 2-3x/week. I would guess the soil drainage is fairly normal.

2. How can I tell if I am over-watering or under-watering by looking at the plant?

Thanks.

RE: How much water for rhododendron?

It's really impossible to give a number in gallons of water. There are just too many factors involved: soil composition, drainage, water holding capacity, atmospheric moisture, air temperature, etc.

In general, a thorough soaking once a week unless there is substantial rainfall is better than 2 to 3 times per week. If the leaves tend to curl even when temperatures decrease overnight, water is needed. Overwatering is more difficult to detect, but if there is good drainage and you stick to the once a week soaking you should not experience any problems.
