Light Conditions
Gerbera plantaginea Harv. var. pusilla Dummer requires bright, indirect light for healthy growth. Direct sunlight can burn the leaves and damage the flowers, so it is recommended to place the plant in a shaded area with access to some natural light.
Temperature Requirements
The ideal temperature range for Gerbera plantaginea Harv. var. pusilla Dummer is between 15°C to 25°C. The plant cannot withstand extreme temperatures, especially below 10°C, which might stunt its growth or cause the flowers to wilt. It is important to keep the plant away from drafts or sudden temperature changes.
Soil Preferences
Gerbera plantaginea Harv. var. pusilla Dummer prefers well-draining soil with a pH range of 6 to 7.5. The soil must be rich in organic matter and nutrients for the plant to thrive. The soil must also retain moisture without becoming waterlogged, as too much moisture can cause root rot and damage to the plant.
Cultivation Methods
The Gerbera plantaginea Harv. var. pusilla Dummer prefers partial shade to full sun and requires well-drained soil for optimal growth. It's a hardy plant that can withstand drought conditions, high humidity, and moderate cold temperatures. It can be propagated by division, seeds, or stem cuttings, with stem cutting being the easiest method of propagation.
When planting, it's advisable to dig a hole slightly shallower than the root ball and twice as wide as the root ball. Gently loosen the root ball and place the plant in the hole with the top of the root ball level with the soil surface. Cover the roots with soil and firm it in place, then water the plant well.
Watering Needs
The Gerbera plantaginea Harv. var. pusilla Dummer requires regular watering during the growing season. Water the plant thoroughly, allowing the soil to dry slightly between waterings. Be careful not to overwater, as this can lead to root rot. During the dormant season, water the plant sparingly.
The plant prefers soil that's consistently moist but well-drained. If you're growing the plant in a container, make sure it has drainage holes to prevent waterlogging.
Fertilization
It's important to fertilize the Gerbera plantaginea Harv. var. pusilla Dummer regularly to keep it healthy and promote growth. Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium, and apply it every four to six weeks during the growing season. Follow the manufacturer's instructions for proper dosage and application.
If the leaves of the plant begin to turn yellow, it may indicate a deficiency of nutrients like iron, magnesium, or nitrogen. In such cases, use a suitable fertilizer that provides the required nutrients to the plant.
Pruning
The Gerbera plantaginea Harv. var. pusilla Dummer doesn't require much pruning. However, removing spent flowers and dead leaves can help maintain the plant's appearance and prevent pest and disease problems. Pinch off the dead flowers and leaves and dispose of them to prevent the buildup of harmful pathogens.
If you notice any diseased or damaged branches, remove them promptly to prevent the spread of disease to other parts of the plant. Use a sterilized pruning tool to make clean cuts, and dispose of the affected plant material appropriately.
Propagation of Gerbera plantaginea Harv. var. pusilla Dummer
There are several methods by which Gerbera plantaginea Harv. var. pusilla Dummer can be propagated. The following are some of the common propagation methods:
Seed propagation
Gerbera plantaginea Harv. var. pusilla Dummer can be propagated from seeds. Seeds should be collected from mature plants and cleaned of any debris. They can then be sown in seed starting mix and kept in a warm, moist environment. The plants should be kept in a bright, sunny spot and kept well-watered. The seeds will germinate in about 2-3 weeks.
Division
Gerbera plantaginea Harv. var. pusilla Dummer can also be propagated by dividing the plant. This should be done in the early spring or fall when the plant is not actively growing. Carefully dig up the plant and gently separate the roots, making sure each section has some roots attached. Replant each section in its own pot or in the ground.
Cuttings
Another way to propagate Gerbera plantaginea Harv. var. pusilla Dummer is by taking stem cuttings. Cut 4-6 inch sections from the plant and remove the lower leaves. Dip the cut ends in rooting hormone and plant in a pot with moist potting soil. Cover the pot with a plastic bag to create a humid environment and place in bright, indirect light. Once the cuttings have rooted, they can be transplanted into their own pots.
