General Plant Information

The Eureka Lemon Tree is a small evergreen tree that produces the classic, football-shaped, tart fruits that we are accustomed to buying at the grocery store and using in recipes. Eureka lemon trees grow vigorously and produce heavy crops of fruits all year round. 

The Eureka lemon was introduced to Los Angeles in 1958, from seeds that originated in Italy. But the lemon tree’s history goes back thousands of years.

The lemon tree is thought to have originated in Myanmar (Burma) or Assam, India. From there, it made its way through Persia, to the Middle East, and then onto the Mediterranean. It was introduced to the Americas by Columbus in 1492 and then spread further through the Spanish Conquest.

Lemons have a long history of being used medicinally, symbolically, and for beauty purposes. The ancient Romans didn’t even use them in cooking, instead prizing them for decorative purposes and as a status symbol. Ancient Egyptians used lemon oil to embalm the dead. In the 1500s, Venetian women used a mixture of lemon juice and licorice bark to dye their hair blonde. The British Royal Navy used lemons to protect against scurvy.  Lemon juice was even used to create invisible ink! As far back as 2000 years ago, the Greeks and Persians used this ink in espionage and to transmit wartime correspondences, a practice that continued in some form all the way up through WWII. 

Today, lemon trees still have a dizzyingly wide variety of uses across culinary, household, medicinal, beauty, fragrance, landscaping, and decorative applications. Here are just a few: 


Lemons are used for their juice, zest, and pulp. They’re versatile when used with poultry, fish, and vegetable dishes, in soups, sauces, and marinades. Lemons are also used for preserving and pickling and can be used for meat tenderizing. 

Delicious lemon-based options abound in baking: lemon bars, cakes, cookies, pies, and lemon curd. 

In terms of beverages, we have our superstar, lemonade. Lemons are used in a wide variety of cocktails, for their juice and as a garnish. And there is also the Italian lemon liqueur, limoncello

Cleaning & Household

Lemon juice can be used as a natural cleaner and disinfectant for surfaces, cutting boards, and kitchen utensils. It can also remove stains, freshen the air, and act as a natural deodorizer. Lemon peels can be used to make DIY citrus-infused cleaners, to get rid of ants, and can be placed in garbage disposals to freshen the scent. 


Lemons are high in vitamin C, bioflavonoids, and powerhouse antioxidants like polyphenols. 

Many people enjoy drinking lemon water as a part of their morning routine. 


Lemon trees have glossy green leaves and fragrant white blossoms, which add beauty and fragrance to gardens and landscapes. Their evergreen foliage provides shade and privacy, making them a popular choice for landscaping purposes.

Aromatherapy & Fragrance

Lemon oil is used in aromatherapy for its mood-boosting and invigorating properties. It also can ease anxiety. Lemon oil has antibacterial and antifungal properties

Eureka Lemon Tree Information and Care

Our Eureka Lemon tree is grown in Standard and Semi-Dwarf. The standard citrus tree has a single trunk with the canopy raised above the main trunk.  The Semi-Dwarf grows like a bush with the canopy low to the ground. They are easier to pick than standard trees but need enough room to walk around them. These are also great for pots! Standard trees are often planted near a walkway since they can be walked under. Although a citrus tree can grow over 20 feet tall, prune to keep them short to desired height. Many grow their Eureka Lemon tree 9 – 15 feet tall. When it comes to spacing, plant citrus trees as close as 9-12 feet apart. Provide more space to allow for larger growth. A great choice for the home garden. Its small size will serve as a beautiful ornamental, as well as provide many fruits.

How To Plant, Water, and Fertilize Eureka Lemon Citrus Trees

Plant an Eureka Lemon tree in the full sun. Amend the soil with high-quality planting mix and fertilizer to improve the soil. Water a newly planted tree twice per week during the Spring through Summer. Water once per week in the Fall and Winter, while the weather is cool. Consequently, trees in hot climates or sandy soils may need water more frequently.

Spring is the most important time to fertilize a citrus tree. Use citrus food fertilizer with a 2-1-1 NPK ratio in the Spring through Summer. To promote growth, there is twice as much nitrogen to phosphorus and potassium. Blood meal and manure are great organic sources of nitrogen. Use a fertilizer with more phosphorus and potassium like bone meal during the Winter to promote flowers and fruit. Lemons are less attractive to birds and animals like squirrels.


Size and Spacing

Plant most citrus trees about 10 – 15 feet apart. Some varieties like Grapefruits and Oranges can grow larger.

Planning is the most important step when planting a tree. Plant your tree where it has enough space to grow to its full potential. Otherwise, your tree will grow into your surrounding trees.  A tree that can grow taller with faster growth will overshadow nearby trees. You may need to move other trees to allow for the one that is thriving rather than cutting back one that naturally grows fast and tall.

Planting Information

Step One:

Soil and Planting: Plant in soil that drains well. Dig a hole that is as deep as the tree’s roots and at least twice as wide.

Step Two:

Place the tree in the hole and backfill around the plant’s roots with a mixture of the native soil and high-quality planting mix that has washed sand and organic fertilizer.

Step Three:

Create a basin around the roots drip zone so that water collects. Water deeply until the roots and nearby soil is saturated and reaches field capacity.

Plant Care Information

How To Water

The quantity and frequency of water to provide is based on the tree’s maturity – Fully saturate most soils with water once per week during the early spring. Increase to twice per week as the weather warms. Water 3 times per week or more during hot summers. Provide about 5 gallons of water for a 5 gallons size plant, 15 gallons of water for a #15-size container plant, and 25 gallons for a #25 depending on soil type. Sandy soils can hold less water required more frequently, while clay soils can hold more water and require less frequent irrigation. Young trees with less developed roots require water more frequently while mature plants with developed roots will require less frequent watering.

Fertilizer and Plant Nutrition

Fertilize your tree every 3-4 months. Use a complete balance fertilizer with a 1-1-1 or 2-1-1 NPK ratio during the Spring and Summer growing season, and a formula with more phosphorus and potassium before the tree flowers to improve fruit production and development.

Winter Pruning and Summer Thinning

Prune your tree to allow light into its center for proper growth and fruit production. 

Prune fruit trees in the Winter to maintain size and shape to prepare for Spring growth. Thin the tree in the Summer, and remove excessive fruits. Remove any dry twigs and branches. Cut off any new growth below the graft or very low in the tree, this will direct the plant’s energy to its main branches. Thin your trees during the Spring and Summer seasons to ensure the plant’s energy is directed as desired. Harvest ripe fruit to prevent undesired pests.

Harvesting and Pest Management

The basics of integrated pest management is cleanliness and the use of a combination of methods. This means we use of organic pesticide when the pest population reaches a threshold that requires action. Horticultural oils such as Neem oil is an organic pesticide that controls tiny, soft bodied insects. Use organic Bordeaux and Liqui-cop to manage fungus causing diseases such as powdery mildew, rust, and leaf-curls.

Keep a clean environment, free of weeds and dropped fruit that host insects or attract animals. Harvest when fruit reaches size and store indoors. Use repellants and bird netting to protect your harvest from other animals.

Sun Exposure: Full Sun

Plant Trees under at least 4-6 hours of direct morning sunlight in fertilized soil that drains well. Provide enough water to saturate roots at the right frequency to develop good-quality fruits.  To grow healthy trees, trim using proper techniques at the right time to prevent biotic pest problems and protect from abiotic Stresses like wind and heat. Sunlight Sensitive plants can burn if they receive direct afternoon sunlight in hot climates due to heat stress. Use shade to prevent this damage.

The two factors that determine if a deciduous fruit trees will grow well and produce fruit in a certain area are the Chill Hour Requirement and the Cold Hardiness. “Chill hours” are the amount of cold a deciduous fruit tree need to produce fruit. This is measured in the number of hours below 45 degrees Fahrenheit a plant must experience during its winter dormancy. Paradise Nursery only grows Low Chill fruit trees that meet the chill requirements of all areas of the United States.

The second factor is Cold Hardiness. Cold Hardiness refers to the minimum temperature a plant can tolerate. The USDA’s Cold Hardiness Zones indicate the average minimum winter temperatures of areas. Based on the shipping zipcode, our website will only allow you to add plants to your cart that grow within your USDA Hardiness Zone, and tolerate your climate.

Pollination & Propagation

(Grafting/Cutting) Most of Paradise Nursery’s edible plants are self-fruitful. Self-pollinating trees do not require an additional tree to produce fruit. For your convenience, we have indicated which trees require a pollinator, and their associated pollinators. Only the sweet cherries, avocados, and some plums require a pollinator. All of our other propagated edible plants do not require a pollinator. All of our edible plants are either grown from cuttings, budded, or grafted. This way, we can ensure that our plants are high quality and fruit immediately. Plants will generally begin fruiting within a year of planting.
