I planted a Meyer Lemon tree 8 years ago and for 3 years it yielded beautiful, juicy, thin- skinned, seedless lemons. Then disaster struck! For the past 5 years, it has produced an abundance of bitter lemons with green insides instead of yellow insides. Whatever happened is an absolute mystery to me. HELP! Now I just enjoy its ornamental value. Maybe I can sell the bitter lemons to Schweppes and make a fortune ;-)
