I've a four-foot deep privet hedge that needs replacing. I'd like to plant fruit bushes (gooseberries, blackcurrant etc) or trees (like espalliered apple trees, maybe?) It gets the sun from early morning till about 4 o'clock in the afternoon
Without knowing what zone you're in, it's hard to be much help but I've had great success using kumquats as an easily maintainable hedge. I'm in central CA so we have a pretty mediterranean climate year-round and the soil is more on the acidic side. As a good rule of thumb, if oranges or other citrus grow well in your area, kumquats should do well also. Hope this helps and good luck!
