The Eureka lemon tree is easily the most popular lemon in the United States. This lemon got its start nearly 200 years ago in Los Angeles and has since taken the world by storm.
The Eureka lemon is a delicious treat used in countless dishes from simple lemon water to 5-star main courses. You can even use this lemon in candy recipes and preserves.
Let’s take a look at the history of this lemon, what you’ll need to grow your own, and what you can cook when life hands you lemons.
History of the Eureka Lemon
The Eureka lemon tree has an interesting history. Prior to California entering into the lemon industry, most lemons in America were shipped in from Italy. It was actually the Lunario lemon that was the predecessor of the Eureka.
In 1858, the Eureka lemon tree was first grown out of seedlings planted in California. It wouldn’t be until 1877 that this lemon was first introduced to the public. Today, the Eureka lemon tree is easily the most popular lemon in the United States and one of the most popular in the world!
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.
The fruit is typically oval to round with a pitted yellow skin. The flesh of this lemon is greenish yellow with a low seed count. The eureka lemon tree is amazingly consistent in terms of both how it grows and the taste and texture of the fruit.
If you’re thinking of growing your own, here’s what you should know.
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.
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.
With that said, access to pollinators and other plants in its flower group as well as some outside time can all help with the pollination.
Now that you’ve got a eureka lemon in your living room, how do you take care of it?
These are full sunlight trees. They love to soak up as many rays as they can get. This tree will do best out in the sun in your garden. If you’re growing this indoors, you might want to make sure that it is parked near a window, or you can carry the planter outside in the warmer months to let the tree get some natural sunlight.
The eureka lemon is a tolerant plant. It doesn’t need extreme watering, but depending on the humidity of your environment, you should water this tree around twice each week. Make sure the soil is damp, but not soaking.
If you’ve got your eureka potting, be on the lookout for root rot. This can happen if your container doesn’t have adequate drainage and you water too frequently. You’re going to want to make sure that a potted lemon tree is in a container that is not only big enough to accommodate the final size, but also has drainage in place to prevent any rot from taking hold.
You’re going to want to tackle pruning your lemon tree somewhere between February and April. Before spring really gets started and right around when winter is just starting to end.
Prune healthy branches about a quarter inch above a healthy bud to promote and direct new growth. Branches thicker than an inch will need to be sawed and cut with care paid to not harm the tree.
If you spot dead or dying branches, make sure to prune those away in the early spring to promote more energy being given to the fruiting branches.
This is a good beginner fruiting tree partly because of how forgiving it is when it comes to pruning mistakes.
