Soil Requirements
The ideal soil type for Phlox austromontana Coville ssp. vera Wherry is slightly acidic, well-drained soil. It cannot tolerate heavy and waterlogged soils, as this can lead to root rot. Adding organic matter or compost to the soil can improve drainage and fertility.
Cultivation Methods
The plant Phlox austromontana Coville ssp. vera Wherry thrives well in areas with a cool climate and well-draining soil. It would be best to plant it in a location with partial shade, especially during the hottest parts of the day. If the soil in your area is not well-draining, you can amend it with organic matter or create a raised bed. You can propagate Phlox austromontana Coville ssp. vera Wherry through seeds or stem cuttings.
Watering Needs
Phlox austromontana Coville ssp. vera Wherry prefers moist but well-draining soil. Water it regularly, especially during the growing season, to keep the soil constantly moist. Avoid overwatering or leaving the soil waterlogged, as it can lead to root rot.
Fertilization
You can fertilize Phlox austromontana Coville ssp. vera Wherry with a balanced fertilizer in the early spring, just before new growth appears. You can also apply a slow-release fertilizer halfway through the growing season. Always follow the manufacturer's instructions and avoid overfertilizing, which can damage the plant.
Pruning
Phlox austromontana Coville ssp. vera Wherry requires minimal pruning. You can deadhead spent flowers to encourage the plant to produce more blooms. In the late fall or early spring, you can cut back any dead or damaged stems to prevent the spread of diseases or pests. However, avoid pruning too much, as it can affect the plant's growth and flowering potential.
Propagation of Phlox austromontana Coville ssp. vera Wherry
Propagation of Phlox austromontana Coville ssp. vera Wherry can be done through both seeds and cuttings.
Seed Propagation
The plant produces seeds in early summer which can be collected for propagation. The seeds should be sown on a moist, well-drained soil mix in a seed tray. They should be covered with a thin layer of soil mix and kept in indirect sunlight. The ideal temperature for germination is around 70°F. Germination may take 1-3 weeks depending on conditions. Once the seedlings are established, they can be transplanted to their final location.
Cutting Propagation
Propagation by cuttings involves taking 2-3 inch long stem cuttings from a healthy plant. The cuttings should be taken in early summer when the plant is actively growing. Dip the cuttings in rooting hormone and plant them in a well-draining potting mix. Cover the pot with a plastic bag to keep humidity high and place it in indirect sunlight. The cuttings should root within 2-3 weeks and can be transplanted to their final location once they have established good roots.
