growing citrus in zone 7 (montgomery county MD)?
Are there varieties of citrus (dwarf grafted lemons and limes) that will grow well enough to produce fruit in our zone?
If so, where can they be purchased locally?
Montgomery County Maryland
Citrus are tropical and will not grow reliably outdoors in Maryland. Occasionally we may have a winter that will not kill them, but they must be in pots that can be moved indoors most winters. Yes, they produce edible fruit. The Improved Meyer Lemon is a suggested variety and probably the most cold tolerant.
