Eureka Lemon Tree and Fruit Characteristics
The Eureka lemon tree is ideal for small gardens or even indoor spaces because it is a very small lemon tree. The branches also have a very short spread which gives this tree a small total footprint.
Planting Zones
This is an interesting point for the eureka lemon. It is technically classified with zones 8-10, but because it is so easy to grow and so hearty, you can grow it in any zone as long as it’s indoors and has enough sunlight.
Size and Spacing
Technically you could let this tree grow to nearly 20-feet tall, but most prune the eureka back down to somewhere between 9 and 15 feet. These trees also need about 9-feet of space between them and their neighbors.
Pollination
Like many commercial fruits, the eureka lemon tree is self-pollinating. You can add a fan to help “shake” the flowers during pollination, but that isn’t strictly necessary. You can also manually pollinate this tree to ensure a good growth cycle, but this is also not necessary.

Culinary uses
Lemon juice, rind, and peel are used in a wide variety of foods and drinks. The whole lemon is used to make marmalade, lemon curd and lemon liqueur. Lemon slices and lemon rind are used as a garnish for food and drinks. Lemon zest, the grated outer rind of the fruit, is used to add flavor to baked goods, puddings, rice, and other dishes.
Other uses

Horticulture
