Eight Steps to Growing Eureka Lemons in Containers

This classic lemon is what you most often see in the grocery store and is known for producing large, juicy lemons of high quality. The flowers produced by this tree are extremely fragrant, making it a prime choice for scented gardens.

Eureka Lemon Fruit

Features of the Eureka lemon:

  • The rind is medium-thick, and the flesh color is greenish-yellow and it is fine-grained and tender.
  • Very juicy with a highly sour flavor, excellent for cooking, especially seafood.
  • The fruit can be used as a salt substitute.
  • The crop is well distributed throughout the year, but mainly in late winter, spring, and early summer.

Eureka Lemon Tree

Features of the Eureka lemon tree:

  • Vigorously growing, with purple-tinged flowers.
  • This tree requires pruning to keep appropriate size, and it not recommended in very humid areas.
  • This variety is moderately hardy to cold temperatures and capable of withstanding brief periods of freezing temperatures.

Where Will Citrus Grow?

With proper care, having a citrus tree such as lemon, lime, grapefruit, kumquat, eureka lemon or orange tree will produce decades of delicious fruit. However, the growing regions in the United States where citrus can be planted into the ground are Limited to regions in California, Arizona, South Texas, Louisiana and Florida.

If you do not live in those regions, we do not recommend planting Eureka Lemons in the ground. However, we consider this a good thing, because it's going to make your lemon growing a lot easier.

Growing Eureka Lemons Outside of Growing Zones

So how do you grow Eureka Lemons outside of these growing zones? You do so by planting your tree in a container. You can use a plastic barrel, a wooden planter, a nice decorative pot, or really any sort of container that has adequate holes on the bottom for drainage.

Another option, which we enjoy, are fabric smart pots which do not have holes, however, the entire container is made of a fabric mesh which allows proper drainage and aeration of the soil.

The Planting Process for Growing Eureka Lemon Trees in Pots

The actual planting process of our trees in pots is very straightforward, with standardized use of potting soil and watering and fertilizing schedules.

You can keep any citrus tree pruned back, but the Eureka lemon is naturally a smaller dwarf type variety which gets to be about 4 to 6 feet, but it will still produce an abundant harvest.

Step 1: Container for Eureka Lemon Trees

The keys to an appropriate container are having sufficient drainage through the material either being some sort of mesh cloth (SmartPots) or having a few holes on the bottom of your planter.

Secondly, the size of the pot should be at least 5 gallons, with our favorite size recommend being 15 gallons. We find that anything above 25 gallons is quite difficult to physically move with only one person. so we recommend 15 gallons as the sweet spot.

Step 2: Soil for Eureka Lemon Trees

Choosing soil for your Eureka lemon trees is simple. All you need is any sort of potting soil. We do not recommend gardening soil or topsoil to use for container gardening. This is advantageous because even if you lived in a citrus growing region, you would have to take into consideration the type of soil.

For example, US Citrus is based in the Rio Grande Valley, and we have a wonderful sandy loam type soil which drains very well. Other types of soil such as different types of clay soils especially with limestone mixed in will have a very difficult time draining and this will adversely affect the root health of your tree.

With a standard potting soil for your container gardening, you do not need to worry about any of these factors. You also don't have to worry about the pH balance of the soil. We recommend growing citrus in containers and using any standard potting soil which is available at your local nursery garden center supply store.

Step 3: Watering for Eureka Lemon Trees

Watering is crucial, typically when citrus is planted into the ground there is a worry of proper drainage and overwatering your tree. Citrus trees planted in the ground prefer to have their roots a bit on the dry side. We have found that if there is proper drainage in container gardening it is difficult to overwater citrus trees.

The best way to figure out how much water your citrus tree needs is to actually look at the tree. If the leaves are wilted and dry, your tree needs more water. After watering, the tree’s leaves should perk up.

Overwatering Your Potted Citrus Tree

Overwatering is a possibility and we find that this especially happens when the trees are indoor and there's a garden saucer used underneath the pot. When there's a garden saucer there is impeded drainage, which is helpful while you're on vacation and cannot water your tree for a week, or when you have your trees indoors to prevent water seeping onto the floors and causing damage.

However, if trees are over-watered, the plant leaves will wilt and may turn a bit yellow and look sad. Watering more will not improve the condition of the tree obviously, and you will likely notice that the soil is waterlogged at this point.

Giving your tree a break by taking it outside if possible or letting the soil drain without a garden saucer in the bathtub for a day is a good solution. Afterward, you can adjust your watering schedule appropriately.

Step 4: Fertilizer for Eureka Lemon Trees

Your Eureka lemon tree will need both macro and micronutrients, just like a human. The macronutrients that all plants need are Nitrogen, Phosphorus, and Potassium. You have likely seen fertilizers and soil which state three numbers together, this is the N – P – K system which shows the concentration and relative amounts of nitrogen, phosphorus and potassium respectively.

These machinations are very important for the development of the root system, the color of the leaves, appropriate photosynthesis, the growth of the trunk of the tree, proper flowering, fruiting, and taste of the fruit. See our blog article on nutrition for more information.

Micronutrients are also very important - think of these as vitamins for humans. They are needed much in smaller quantities and plants can have characteristic symptoms if they have a micronutrient deficiency. We will detail out micronutrients and symptoms of deficiencies in later articles.

Between regular potting soil and the fertilizer we recommend, you will have all the macronutrients and micronutrients that your tree needs and a simple fertilizing schedule for easy and effective fertilizing when you get your tree and for every February, May, and August. See our fertilizer schedule below for amounts that we recommend.

Step 5: Sunlight for Eureka Lemon Trees

Sunlight is crucial to citrus trees, especially citrus being a tropical plant. In most areas of the United States, you want to maximize sunlight with full sun exposure. If you are planting indoors, make sure that it has full sun next to the window, but we would also recommend having a grow light.

Our Grow Light Recommendation

We love SANSI 24W LED grow lights. They have a clean white light because they are full spectrum. They have all the right mix of light spectrum for growth, leaf flush, flower blossoming, and fruit set. 24 watts is a good amount of power for indoor lighting. We recommend placing the grow light anywhere from 6 to 18 inches away from your tree.

Your tree needs 12-16 hours of light a day. You can be very flexible with your light. You can keep it on for many days straight. However, all citrus trees need some dark time.

You can easily use one grow light for 1-3 trees. An easy way is to use one light on a tree for 24 hours at a time.

All grow lights get hot. We prefer SANSI because they use ceramic sinks to dissipate the heat. We have found the majority of grow lights on Amazon to have disturbing safety profiles. Use standard safety precautions, don't let babies and pets stare directly into the light or touch the heat from the grow light!

Our socket/clamp Recommendation:

We recommend the following clamp for your tree. It has a UL certified socket, electrical cord included as well. And it fits the Sansi bulb!

Citrus does best when it has six hours of sunlight a day. If the temperature is consistently above 90° especially for younger trees, there may be some wilting of the leaves. This wilting will reverse however and at this point, it would be advantageous to keep your tree by elementary and partial shade.

Step 6: Winter Protection for Eureka Lemon Trees

We recommend that under freezing temperatures, you move your citrus tree into a warmer area such as a garage or indoors for the entire winter. This point you can utilize grow lights for continued growth.

There is nothing more frustrating than losing years of work and future decades of fruit than losing your citrus tree to a freak cold-snap which occurred while you were vacationing out of town! Citrus can die with exposure to temperatures in the teens for even up to 12 hours.

Step 7: Where Do I Buy My Eureka Lemon Tree?

First of all, if you live in the states of California, Arizona, Louisiana, or Florida, you will need to purchase your citrus tree locally as citrus cannot be imported into your state because of USDA regulations.

Step 8: Harvesting Your Eureka Lemons

The crop is well distributed throughout the year, but mainly in late winter, spring, and early summer.
