Lighting Requirements

Lemon geraniums prefer bright, indirect light but can tolerate some direct sunlight. East- or west-facing windows are ideal, as they provide gentle, indirect light. Avoid placing your plant in a south-facing window, as it may receive too much direct sunlight, leading to scorching or leaf drop. If you don't have a window with natural light, you can also use grow lights to supplement the lighting.

Watering Your Lemon Geranium

Watering is crucial for the health of your lemon geranium. Overwatering is the most common cause of death in these plants, so it's essential to get it right. Check the soil moisture by sticking your finger into the soil up to the first knuckle. If the soil feels dry, it's time to water. Water your plant thoroughly, making sure the pot drains well to prevent waterlogged soil. Reduce watering in the winter months when the plant is dormant.

Humidity and Temperature

Lemon geraniums prefer a relatively high humidity, typically above 50%. You can increase the humidity around your plant by placing it on a tray filled with water and pebbles or using a humidifier. As for temperature, these plants thrive in temperatures between 65°F (18°C) and 75°F (24°C) during the day and no lower than 55°F (13°C) at night. Avoid placing your plant near heating or cooling vents, fireplaces, or drafty windows.

Fertilization

Feed your lemon geranium with a balanced, water-soluble fertilizer during the growing season (spring and summer). Dilute the fertilizer to half the recommended strength to avoid burning the roots. You can also use a fertilizer specifically formulated for flowering plants, as it will promote more blooms. Avoid fertilizing during the winter months when the plant is dormant.

Pruning is essential to maintain the shape and size of your lemon geranium. Remove any dead or damaged leaves or stems, and cut back long stems to encourage bushy growth. You can also prune your plant to maintain a desired shape or size. Use clean, sharp scissors or pruning shears to prevent spreading diseases. After pruning, remove any weak or spindly growth to promote healthy growth.

Pest Control

Check your plant regularly for pests like spider mites, mealybugs, and aphids. If you notice any pests, isolate your plant to prevent the infestation from spreading to other plants. Treat your plant with insecticidal soap or neem oil according to the product's instructions. Make sure to read the label carefully and follow the instructions to avoid harming your plant.

Propagation

You can easily propagate your lemon geranium through stem cuttings or leaf cuttings. Take 3- to 4-inch stem cuttings from the tip of a healthy stem, removing lower leaves and dipping the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep the soil moist. You can also propagate using leaf cuttings, placing the cut end in a pot filled with moistened potting mix. Keep the soil moist and warm until roots develop.

Common Problems and Solutions

Some common problems you may encounter when caring for your lemon geranium include leaf drop, yellowing leaves, and root rot. Leaf drop can be caused by overwatering, underwatering, or sudden changes in temperature or humidity. Yellowing leaves may indicate too much direct sunlight, overfertilization, or root bound conditions. Root rot is often caused by overwatering or poor drainage. To address these issues, adjust your watering schedule, provide more indirect light, or repot your plant in fresh potting mix with good drainage.

With proper care and attention, your lemon geranium can thrive and bring joy to your home or office. By following the guidelines outlined in this article, you'll be well on your way to becoming a successful lemon geranium caregiver. Remember to monitor your plant's condition regularly, and don't hesitate to reach out if you have any questions or concerns. Happy planting!
