Q.Orange Tree And Depth Of Soil
We have a dwarf orange tree about 6-7 years old which was planted by a nursery 4 years ago. It has hardly grown, but it had 5 oranges on it the first season and none after that nor any flowers. The leaves have always been a bright green, and it seemed healthy. I just recently found out that we have been overwatering it as the reading was off the gauge. it was only twice a week for about 5 minutes, but I think our soil must not drain very well. I am letting it dry out, but even about 3 weeks later it is still off the gauge. The soil depth around the tree is about 4 inches; under that is either rock or hard clay. Is that soil depth enough to sustain it and allow it to thrive eventually once the water issue is solved? Thank you so much for your answer.

Hello again! So, yes. That does look like could be overwatering, but I would not rely on the gauge if it is reading wet after 3 weeks.Test it against others to get a better idea if the meter is the problem, because that's a bit strange. I'd dig a finger or tool as deep as you can when you know it is about time to water and There is a chance that whatever compacted materials under your soil layer could be holding water if it is a dip or a low spot within the harder layer. I don't know if I find that the most likely culprit though. I have 4 citrus that I keep indoors in container, and I know that they will adapt to those cramped conditions with just a little help. I don't the the shallow soil depth would have that much of an effects, besides for anchoring. It may tear out of the ground easier. Doesn't seem like that is a big worry given the time it has been there. Now, the big issue I'd worry about is feeding. Citrus are hungry. Testing your soil will be necessary to know when and what to feed.
