A fascinating feature of this plant is that it often blooms and bears fruit simultaneously – a true spectacle of nature. The glossy, dark green leaves provide a wonderful contrast to the bright lemons, creating a fresh, vibrant appearance. If you rub the leaves lightly, they also release a wonderful citrus aroma.

Typical Characteristics:

• Evergreen with fragrant blossoms and edible fruits

☀️ Location, Soil, and More

The lemon tree is an absolute sun worshipper and needs a lot of light to thrive. The right location is crucial for the plant to stay healthy and bear a rich harvest.

• Full sun and warm location

• Preferably sheltered from wind outdoors during summer months

• Requires bright and cool conditions in winter (approx. 5–10 °C)

• Perfect for: a sunny south-facing balcony, terrace, or an unheated, bright conservatory.

🌿 Care of Citrus Limon – Overview

This plant is an absolute eye-catcher, but requires some attention to thrive optimally. It is particularly suitable for plant lovers who enjoy learning about the needs of Mediterranean plants and proper overwintering.

🌱 Growth

• Grows as a compact shrub or small tree

• Grows steadily in height and forms a bushy crown

• Can grow well to 1.5 to 2 meters in a pot or container

• Contributes to a stately, Mediterranean appearance.

🍃 Leaves

• Oval, leathery, and slightly glossy on the surface

• Deep, rich dark green

• Release a light, fresh citrus scent when rubbed

• The evergreen foliage makes the plant attractive all year round.

💧 Watering / Water

Unlike desert plants, the lemon tree is quite thirsty, but hates wet feet.

• Water thoroughly in summer, then allow the top layer of soil to dry out

• Water much more sparingly in winter, but avoid the root ball drying out completely

• Best to water with tap water or a mix of tap and rainwater (citrus plants need some lime!)

• Waterlogging, however, quickly leads to root rot and leaf drop.

🌼 Fertilizing

• From spring to autumn: every 1–2 weeks

• Special liquid citrus fertilizer (with high nitrogen and iron content)

• Stop fertilizing completely in winter (during the cool resting phase)

• Nutrient deficiency quickly manifests as yellow leaves with green veins (chlorosis).

🌱 Substrate

A structurally stable soil climate is enormously important:

• Nutrient-rich and slightly loamy

• Very well-draining (high mineral content like sand, pumice, or expanded clay)

• Slightly acidic to neutral

• A high-quality, special citrus soil is absolutely the best choice here.

🪴 Repotting

• Every 2 to 3 years in early spring (March/April)

• When the pot is completely rooted through

• Terracotta pots are ideal as they regulate moisture well and provide stability due to their weight.

✂️ Pruning

The lemon tree tolerates pruning well to stay in good shape.

• Best time is early spring before new growth appears

• Completely remove inward-growing, crossing, or dead branches

• Overly long shoots can be shortened to promote a more compact crown

• Always use clean and sharp tools.

🌱 Propagating Citrus Limon

Propagation requires some patience but is well achievable in two ways:

☠️ Is the lemon tree poisonous?

Yes – unlike maranta, citrus limon is unfortunately not safe for pets.

• Slightly toxic to cats, dogs, and horses

• Peel, leaves, and stems contain essential oils and psoralens

• Can cause vomiting, diarrhea, tremors, or skin irritation if ingested

👉 You should place it so that your furry friends cannot nibble on the leaves. (For humans, the fruits and blossoms are, of course, completely harmless and a healthy, delicious treat!)

🧠 Other Care Tips

• Winter rest: Lemon trees need a break. In winter, they must be placed in a bright but cool spot (5–10 °C). A warm spot in the living room almost inevitably leads to leaf drop and severe pest infestation (scale insects or spider mites).

• Yellow leaves are a warning sign and often indicate too much water (waterlogging) or an acute iron deficiency.

• The plant loves plenty of sun in summer, but after being moved outdoors in spring, it should spend a few days in partial shade to avoid sunburn on its leaves.

✅ Conclusion

With its Mediterranean charm, wonderfully fragrant blossoms, and bright fruits, Citrus limon is a dream for every plant lover. While it requires proper overwintering and regular fertilization, it rewards you with your own lemon harvest and pure holiday flair on your balcony or terrace.
