Recently planted (4-6 weeks ago) 4-6 feet dark American arborvitaes. First we were told to water once or twice a week with soaker hose. Then we were told by friend to keep water ongoing. Now our trees are turning yellow and brown. I am concerned that we over watered them. I have not watered them in a couple of days. But now I don't know if they are going to die and how much watering I should do. Is there something to give them to make them come back? They are not to serious yet but some are looking worse each day. |
We have heavy clay soil and it is very easy to over water. We usually dig a hole larger than recommended, break up the walls of the hole then plant. After too many losses we decided to invest in a moisture meter. Small investment great rewards. |

To make it more complicated, yellowing can be a sign of over watering or under watering or occasionally of some other problem. You might want to check with your supplier or with your County Extension to see if they have any additional guidelines to offer. |
My experience is the yellowing is due either to overwatering, under or over nourishing. Hard to pinpoint without testing the soil. My first step is to feel the moisture in the soil by gently feeling around the root level. If sopping, add some dry soil and gently work it around. See how that goes over a few days. Depending on what you have done for fertilizer already, if things look better or the same, I might add a weak mixture of organic fertilizer. The watering recommendations of the previous writer seem right on. Good luck. I successfully brought back my seven year old hibiscus that was yellowing by taking care in watering and nourishing. |
