Everything it needs
9 essentials at a glance
Watering
Pelargonium graveolens prefers to dry out slightly between waterings.
Water thoroughly when the top inch of soil feels dry, typically every 1-2 weeks. In the growing season (spring and summer), increase frequency if the soil dries out quickly. In fall and winter, reduce watering to once every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement includes south or west-facing windows. While it can tolerate partial shade, too little light may result in leggy growth and reduced fragrance.
Soil
Pelargonium graveolens prefers well-draining soil with a pH range of 6.0 to 7.0.
A mix of potting soil, perlite, and sand is recommended for optimal drainage. Ensure the pot has drainage holes to prevent water accumulation.
Humidity
The sweet scented geranium prefers moderate humidity levels around 40-60%.
To increase humidity, consider misting the leaves or placing a humidity tray filled with water and pebbles beneath the pot. Signs of low humidity stress include browning leaf edges and leaf drop.
Temperature
Ideal temperatures range from 65-75°F (18-24°C) during the day and slightly cooler at night.
Pelargonium graveolens is hardy in zones 9-11. It can tolerate brief periods of cooler temperatures but should be protected from frost.
Fertilizing
Use a balanced, water-soluble fertilizer with an NPK ratio of 10-10-10 or similar.
Fertilize every 4-6 weeks during the growing season and reduce or stop feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Pelargonium graveolens in early spring to promote bushy growth and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. Deadheading spent flowers can encourage more blooms and prevent the plant from going to seed.
Repotting
Repot every 1-2 years or when the plant becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. To repot, gently remove the plant from its current pot, loosen any tightly bound roots, and place it in fresh potting mix, ensuring the crown is at soil level.
Propagation
Propagation can be done through stem cuttings, division, or seeds.
For stem cuttings, take a 4-6 inch cutting from a healthy plant, remove the lower leaves, and allow it to callous for a few hours. Place the cutting in a well-draining potting mix and keep it moist until roots develop, usually within 2-4 weeks. The best time for propagation is in spring or early summer.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or poor drainage.
How to fix it

Leggy growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location with more direct sunlight.
Browning leaf edges
Why it happens
Low humidity or underwatering.
How to fix it
Increase humidity levels or adjust watering frequency.
Root rot
Why it happens
Excess moisture in the soil.
How to fix it
Reduce watering and improve drainage; consider repotting if severe.
Pest infestations (aphids, spider mites)
Why it happens
Dry conditions or stress.
How to fix it
Regularly inspect the plant and treat with insecticidal soap or neem oil.
Care through the year
Spring
In spring, prune back any dead growth and begin a regular watering and fertilizing schedule as the plant comes out of dormancy.
Summer
During summer, ensure the plant receives adequate sunlight and water more frequently as the soil dries out faster. Monitor for pests.
Fall
In fall, gradually reduce watering as the plant prepares for dormancy. Stop fertilizing and consider bringing the plant indoors if temperatures drop.
Winter
In winter, keep the plant in a cool, bright location and water sparingly. Avoid over-watering to prevent root rot during the dormant period.
Toxicity & Safety
Pelargonium graveolens is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset. Always monitor pets around plants.
