Growing Pelargonium Graveolens
If you want to give your Sweet-scented geraniums the time of their life, proper sunlight exposure is what you are looking for. These plants prefer locations with full sunlight, but they can also do just fine in partially shaded ones. In regions with very warm climates, your flowers will actually benefit from some afternoon protection from harsh sunlight. However, shady conditions for too long will cause your plants to grow somewhat leggy.
Like most tropical species, Pelargonium graveolens plants grow at their best in hot, humid environments. These flowers can also do just fine in dry climates and will withstand short periods of light frost. If you live in a zone with cooler temperatures, we recommend you transplant your plants in pots and bring them inside in early autumn.
Sweet-scented geraniums are typically trouble-free when it comes to pests and fungal diseases. However, common pests like aphids, spider mites, or mealybugs can bother these shrubs occasionally. Due to this, you must prepare yourself for any possible infestation. If you notice any suspect presence on your plants, handpick them if possible and apply suitable insecticides/pesticides.
Planting Pelargonium Graveolens
Pelargonium graveolens plants thrive in well-draining soils that are not too rich in nutrients or organic matter. In general, most herbaceous plants can lose their strong fragrance if you are growing them in rich substrates. And these shrubbies are no different! They will tolerate a wide range of soil pH, but your geraniums will perform best in slightly acidic growing mediums.
Overall, geraniums do not require too much fertilizer to grow healthy and happy. Potted plants, however, will demand more frequent fertilizing than those from the garden. Feed your potted geranium flowers with a balanced fertilizer at ½ strength once in spring. If they look a bit lifeless, you can repeat this process once every three to four weeks during the summer.
Sweet-scented geraniums are shrubs by nature, so they will need occasional pruning and pinching to look all full and bushy. The ideal time to prune your plants is in spring because this will give them enough time to produce flowers. You should remove all damaged or spent blossoms to allow new ones to show up. Moreover, if your shrubs grow larger than you might want, you can always prune them back during any season.
Watering Pelargonium Graveolens
Pelargonium graveolens plants are very tolerant of drought, making them excellent start-ups for beginners or forgetful gardeners. These shrubs do not enjoy soggy conditions or waterlogging, so you should avoid over-watering in their routine.
For best results, make sure you always check the substrate in-between waterings. When the soil feels dry to the touch at 1 inch (2.5 cm) deep, you can provide your plants with a touch of water. If you want to grow your Sweet-scented geraniums indoors, look for pots that have drainage holes at the bottom.
Although Pelargonium graveolens plants are drought-tolerant, prolonged periods of dry soil can damage them. When you under-water your shrubs, their foliage will turn yellowish-brown and eventually fall off. But no worries! You can fix this problem by giving them a nice, deep soaking and adopting a proper watering routine.
Propagating Pelargonium Graveolens
Even if you can always start Pelargonium graveolens plants from seed, most specimens are hybrids and will not come true to the parent. However, this is not a reason to get all sad and discouraged! You can easily propagate these shrubby friends through stem cuttings with little to no experience required as a gardener.

- How to grow a plant from seed
- After filling the pots with soil, the soil surface should be lightly sprinkled with warm water and left for one day to warm the earth to the required temperature (21-22 °C). Then with your finger or suitable tool to make small holes at a distance of two cm from each other. Seeds sprinkle with a layer of soil thickness of one cm.
- The soil should be moistened again a little and cover the container with a film, in which small holes are made to ensure air access. At home, geranium is necessary to provide optimal temperature and lighting, but in any case do not put the pots with seeds planted on the windowsill.
- When the first soft green shoots appear, remove the shelter, so as not to create conditions of high humidity for the plant. Now is the time to put the pallets with pelargonium on the windowsill to provide the plant with sunlight, otherwise the cultivation of the flower will take two to three times longer.
- In order to obtain a healthy Bush with strong stems, as well as to strengthen the root system, the soil must be periodically loosened. After the appearance of two real leaves, pelargonium should dive and transplant the Bush into a narrow and high container. Waiting for the appearance of the pelargonium fifth leaf-seedlings should be pinched. This will ensure the growth of the most branched Bush, otherwise-you get a plant with a long thin stem.

Look for healthy stems and cut about 6 inches (15 cm) off them using a sharp and sterilized knife. Once you have your cuttings, remove all leaves from each one but make sure you are letting an upper pair of leaves untouched. For optimal growth, dip the cut ends of your Pelargonium graveolens cuttings in rooting hormone.
Fill a large container or bed with fresh, moist vermiculite. After this process, you must plant your cuttings in their growing medium and place them in a bright, warm location. If you maintain the substrate constantly damp, the cuttings will develop a healthy root system in several weeks.
You can check the progress of your cuttings by pulling them gently once in a while. When you start to feel some resistance, you can transplant them in their permanent spots.
