About This Plant

Eureka Lemon (Citrus limon Eureka) is a dwarf citrus tree variety that originated in California and is one of the most widely grown commercial lemon varieties. Indoors it produces glossy, oval, dark green aromatic leaves, and actual yellow lemons that are edible and true to type. With enough direct light it can produce flowers and fruit year-round.

It produces actual edible lemons indoors. The Eureka is one of the commercial lemon varieties so fruit produced indoors is the same seedless, thin-skinned, intensely flavoured lemon found in grocery stores.

Keep it away from pets. The ASPCA confirms Citrus spp. is toxic to cats, dogs, and horses. The leaves, fruit peel, and essential oils contain psoralens and limonene that cause vomiting, diarrhea, depression, and photosensitivity in pets. Keep it in a room that pets cannot access. Fallen fruits and leaves on the floor are also a risk.

It spends Canadian summers outdoors and overwinters indoors. The Eureka Lemon thrives on warm Canadian summers outdoors on a sunny patio or balcony in full sun from late May through September. The outdoor sun, heat, and outdoor pollination trigger prolific flowering and fruiting. Bring it inside before temperatures drop below 10 degrees C. A south-facing window is the minimum indoor requirement.

Winter Slowdown

Growth slows significantly indoors from November onward as light levels drop. The transition from outdoor sun to indoor winter conditions can trigger leaf drop. Bring it indoors gradually before the first frost, keep it in your sunniest south-facing window, and water less frequently. Fruit that is already on the tree will continue to ripen slowly through winter.

Toxicity

Toxic to cats, dogs, and horses, confirmed by the ASPCA (Citrus spp.). The leaves, fruit peel, and essential oils contain psoralens and limonene. Symptoms include vomiting, diarrhea, depression, and photosensitivity. Keep in a room that pets cannot access. Fallen fruits and leaves also pose a risk.

Pests

Scale insects, spider mites, and aphids are the main pests. Aphids commonly appear on new growth and flower buds. Scale appears on stems and the undersides of glossy leaves. Check all parts of the plant when watering.

Other Plants You Might Like

Not sure this is the right fit? Here are three other plants our Canadian customers love. All ship across Canada and thrive in Canadian homes.

Calamondin Orange. Fruiting citrus, smaller fruit.

For another dwarf fruiting citrus that produces smaller but decorative oranges year-round in a bright Canadian room, the Calamondin Orange has the same bright white fragrant flowers and ornamental fruit.

Coffee Plant. Glossy leaves, potential fruit.

For another glossy-leaved plant that can eventually produce fruit with patience and good light, the Coffee Plant has highly glossy dark green leaves and can produce actual arabica coffee cherries after several years.

Ponytail Palm. Outdoor summer, indoor winter.

For another plant that thrives outdoors on a sunny Canadian balcony in summer and overwinters well indoors, the Ponytail Palm has a striking bulbous base and long arching leaves with minimal care needs.

Common Questions

How often should I water the Eureka Lemon?

Water when the top two inches of soil feel dry. In summer outdoors this may be every three to five days. Indoors in a Canadian winter, every seven to ten days. Never let it dry out completely as leaves yellow and drop. Never leave it in standing water. Our indoor plant watering guide shows how to check moisture correctly.

How do I pollinate it indoors?

When the fragrant white flowers are open, use a small clean paintbrush to transfer pollen between flowers by gently brushing the centre of each flower. Do this on several consecutive days when flowers are open. Outdoors insects do this naturally. Successful pollination is indicated by the base of the flower swelling into a tiny green fruit.

Is the Eureka Lemon toxic to cats and dogs?

Yes. The ASPCA confirms Citrus spp. is toxic to cats, dogs, and horses. The leaves, peel, and essential oils contain psoralens and limonene causing vomiting, diarrhea, depression, and photosensitivity. Keep it in a room that pets cannot access. Fallen fruits and leaves are also a risk.

When should I move it outdoors in Canada?

Move it outdoors after the last frost date in your area, typically late May in Ontario and Quebec. Start it in partial shade and transition to full sun over one to two weeks to prevent sunscorch. Keep it outside until September or until nighttime temperatures regularly drop below 10 degrees C.

Will it fruit indoors in winter?

Fruit already on the tree when it comes indoors will continue ripening slowly through winter. New fruit production slows but does not stop in a south-facing window. The most prolific fruiting happens outdoors in summer. Read our tips on keeping plants alive in winter for the transition indoors.

How to take care of Citrus Eureka Lemon

Good to Know

Sun: Direct to bright

Needs as much direct sun as available. A south-facing window is the minimum indoor requirement. Outdoors in a Canadian summer, full sun is ideal. Without strong light indoors, new fruit production stops.

Light: Bright direct

A south-facing window is essential indoors. From October to February in Canada, keep it as close to the glass as possible. A grow light can supplement natural light during the darkest winter months.

Water: When top 2 inches are dry

Water when the top two inches of soil feel dry. More frequently outdoors in summer. Every seven to ten days indoors in winter. Never leave in standing water. Glossy leaves droop slightly as an early signal of underwatering.

Humidity: Moderate to high

Prefers moderate to high humidity. The dry forced-air heating in Ontario and Quebec homes causes leaf drop and attracts spider mites. A humidifier nearby or grouping with other plants helps through the Canadian heating season.

Pet Friendly: No

Toxic to cats, dogs, and horses, confirmed by the ASPCA. Contains psoralens and limonene in the leaves, peel, and essential oils. Keep in a room that pets cannot access. Fallen fruits and leaves on the floor are also a risk.

Pro Tip

The most reliable way to get substantial lemon fruit from an indoor Eureka Lemon is to put it outside on a sunny patio or balcony from late May through September. A plant that spends summers outdoors will reliably carry fruit through the winter that can be harvested as it ripens.
