We cross-posted ! If you have been adding tree leaves......you should be getting the trace elements you need, but, if you have been adding them to the beds "un composted", that will tie up a lot of the nitrogen in the soil (it's used in "breaking down" the leaves). I still think a soil test is in order......your county extension office can get you the particulars on getting one done, or, there are "on line" places that will do it, or, a simple test kit should be available at your local nursery, or garden center.
