wow, how do you guys get so big trees? That size would be my 4th or 5th year or something of growing from a 3 gallon.. is it better buy a 7 gallon one then? I saw that other post about $20 or $25 3 gallon mangos, however, if we buy it here in CA (even online), it would be at least $60+.. and $100+ for a 7 gallon one (including shipping)..
