Japanese Boxwood

[tricketts]

I planted some new Japanese boxwoods a week ago. The last two days I noticed that the leaves on those along with my Grapefruit tree are now turning yellow. Does this mean they are getting too much water? I want so bad for them to be okay. I also have to boxwood beauties and they are doing fine and get the same amount of water. Any suggestions?

Sounds more like a nitrogen/iron problem. Too much water may be leaching them out of the soil. Those two elements depend on each other to work and both the citrus and boxwoods are heavy iron users. Adding some ironite or a similar product might help. Iron is bad about getting tied up with other minerals in the soil that make it unusable for plants even when there is plenty there. Ironite is chelated to make it available fairly quickly.

I bought one of those soil test kits at home depot. Do you think it will test fairly accurate in telling me if that is the problem?

Most of those only test the PH of your soil. If it's off very far on either the acid or alkali side your iron is probably tied up. If your kit tests for nitrogen you can at least see where that is. Iron added in liquid form is the fastest acting if you can find it.
