Pruning Impatiens Aurella Rydb.
Pruning helps to rejuvenate the Impatiens aurella Rydb. plant and keep it looking neat and tidy. Use sterilized pruning shears to remove dead, diseased, or damaged parts of the plant to prevent the spread of diseases. You can also pinch the tips of the stems early in the growing season to encourage branching and promote bushier growth. Avoid pruning the plant during the hottest part of the day to prevent wilting.
Propagation of Impatiens aurella Rydb.
Impatiens aurella Rydb., commonly known as Yellow Balsam or Orange Balsam, is a herbaceous plant belonging to the Balsaminaceae family. It is native to North America and can be found in wet prairies, riverbanks, and swamps. Propagation of Impatiens aurella Rydb. can be done using different methods, such as seed propagation and stem cuttings.
Seed Propagation
The easiest and most common way to propagate Impatiens aurella Rydb. is by seed. The plant produces small, brown seeds in capsule-like fruits. Seeds should be collected when the fruits are dry and starting to split open. To ensure successful germination, seeds should be cleaned and soaked in water for 24 hours before planting.
The best time to sow Impatiens aurella Rydb. seeds is in early spring when the soil is moist and temperatures are about 20°C. Seeds should be sown in a well-drained soil mix and covered with a thin layer of soil. Water the seeds lightly and keep them in a warm, bright location. Seedlings should emerge in about two to three weeks.
Stem Cuttings
Another way to propagate Impatiens aurella Rydb. is through stem cuttings. This method is useful if you want to produce new plants that are identical to the parent plant. Cuttings should be taken in the spring or early summer when the plant is actively growing.
To take a cutting, pick a stem that is about 8-10 cm in length and has several leaves. Remove any flowers or flower buds from the stem. Dip the cut end of the stem in rooting hormone and plant it in a well-drained soil mix. Water the cutting and cover it with a plastic bag to create a humid environment. Keep the cutting in a warm, bright location but avoid direct sunlight. Roots should form in about four to six weeks, and the plant can be transplanted to a larger pot or to the garden.

Impatiens aurella Rydb., commonly known as Aurelle's touch-me-not, is a species of flowering plant in the Balsaminaceae family. To keep this plant healthy and thriving in your garden, it is important to manage diseases and pests that could potentially damage it.
Common Diseases
The most common diseases that affect Impatiens aurella Rydb. are fungal diseases, such as powdery mildew and leaf spot.
Powdery Mildew: This disease appears as a white powdery coating on the leaves, stems, and flowers of the plant. It is caused by different fungal species that thrive in warm and humid environments. The leaves may turn yellow and drop, leading to stunted plant growth.
Leaf Spot: This disease appears as brown spots on the leaves that are circular or angular in shape, and they may have a yellow halo around them. It is also caused by a fungal infection, which spreads easily in wet conditions. The infected leaves may fall off, leading to defoliation and plant stress.
Common Pests
The most common pests that affect Impatiens aurella Rydb. are aphids, spider mites, and whiteflies.
Aphids: These are small, pear-shaped insects that are usually green or yellow in color. They feed on the plant sap, leaving sticky honeydew on the leaves and stem. This honeydew attracts sooty mold, which can reduce the photosynthetic capacity of the plant.
Spider Mites: These are tiny arachnids that spin webs on the underside of leaves, where they feed on plant sap. They are pale in color and difficult to see with the naked eye. Infested leaves may turn yellow and drop off, leading to defoliation and plant stress.
Whiteflies: These are small, flying insects that are usually white in color. They feed on the plant sap, and their feeding can weaken the plant and cause it to wilt. They also excrete honeydew, which can attract ants and sooty mold.
Managing Diseases and Pests
Here are some ways to manage diseases and pests that affect Impatiens aurella Rydb.:
Cultural Practices: Proper cultural practices can help prevent diseases and pests in the first place. This includes planting the Impatiens aurella Rydb. in well-drained soil and providing it with enough water and sunlight. Make sure there is adequate space between plants to promote good airflow, which can reduce the risk of fungal infections. Dispose of infected leaves and plants appropriately to prevent the spread of disease.
Biological Control: Using beneficial insects, such as ladybugs and lacewings, can help control aphids and spider mites. Additionally, introducing nematodes to the soil can help control soil-borne plant diseases.
Chemical Control: If cultural and biological control methods fail, chemical control may be necessary. Always read and follow the instructions on the pesticide label carefully. Be aware that pesticides can harm beneficial insects and may not be effective against some pests and diseases.
