The Eureka Lemon produces large crops of lemons annually. Bearing fruit all year, this lemon fruit tree produces somewhat knobby, thick-skinned lemons, and each lemon has a short neck at the stem end.
Watering this fruit tree systematically, like once a week is very important, but containerized citrus trees should be allowed to dry between waterings. Fertilizing it 3 times a year with a well balanced citrus fertilizer will benefit the health of Eureka as well. It is easy to espalier, grows vigorously with a spreading and open form, and has fewer thorns than other traditional lemon trees; needs full sun, well-drained soil, and no pollinator is required. This dwarf citrus will average 8-10' tall, and it will get taller unless pruned.
Eureka lemon trees bear multiple crops per year, but the main season is late winter, spring, and early summer. This tree can grow in zones 9-11, but for northern gardeners it needs to be in a pot and brought indoors for the winter. It should be pruned every year or two to keep the tree within bounds and the fruit easily reachable. Can be shaped as a small tree.
The fruits are borne on the outside of the canopy and are frequently held in clusters. The Eureka lemon contains a moderate amount of juice, and is grown primarily for this acidic juice, which can be used to flavor both sweet and savory dishes.
Lemons are very rich in vitamin C and also provide potassium and folic acid. The Eureka Lemon can be kept in a plastic bag in the refrigerator for up to 2 weeks. Lemons stored at room temperature will keep for about 1 week. The juice and zest of lemons can be frozen.
