Light Requirements
The Correa reflexa hybrid 'M' plant thrives in bright to filtered light conditions. However, it cannot tolerate direct sunlight for extended periods. It is recommended to provide the plant with six hours of bright light per day, preferably in the morning or late afternoon.
Temperature Requirements
The ideal temperature range for this plant is between 60 to 75°F (15 to 23°C). It can tolerate temperatures as low as 30°F (-1°C) but only for brief periods. In temperatures above 85°F (30°C), it is best to provide additional humidity to keep the plant healthy.
Soil Requirements
The Correa reflexa hybrid 'M' plant grows well in well-draining soils that are slightly acidic with a pH range of 5.5 to 6.5. A soil mix of peat moss, perlite, and sand in equal proportions is ideal. Additionally, the soil must be moisture-retentive enough to avoid drying out the plant but not too wet as it may lead to root rot.
Cultivation Methods for Correa Reflexa Hybrid 'M'
The Correa reflexa hybrid 'M' requires well-draining soil with a pH level between 5.5 and 6.5 for optimal growth. It is important to ensure the planting hole is wide enough and not too deep to avoid waterlogging. The plant grows best in full sun to part shade positions, and it is essential to maintain consistent moisture levels through regular watering.
The Correa reflexa hybrid 'M' can grow up to 2m high and spread out as much as 2m wide. It is best to space out each plant by approximately 2-3m to prevent overcrowding.
Watering Needs
The Correa reflexa hybrid 'M' requires regular watering to maintain consistent soil moisture. Water the plant whenever the top layer of soil feels dry to the touch. However, avoid overwatering as this can cause root rot and damage the plant's health.
During the hotter and drier months, it is important to water the plant regularly to prevent leaves from dropping and to maintain its lush green appearance.
Fertilization for Correa Reflexa Hybrid 'M'
The Correa reflexa hybrid 'M' does not require heavy fertilization. However, you can add a layer of organic compost to the soil around the plant's root during the growing season to replenish nutrients. It is best to fertilize the plant once a year after pruning to promote healthy and vigorous growth.
It is essential to avoid over-fertilizing the plant as this can cause damage to the plant's growth and overall health.
Pruning Correa Reflexa Hybrid 'M'
The best time to prune the Correa reflexa hybrid 'M' is during the winter months as it is a dormant period for the plant. You can prune the plant by removing any dead or diseased branches and crossing branches causing congestion. Reduce the plant's overall size by approximately one-third, but avoid heavy pruning as this can damage the plant.
Regular pruning helps maintain the plant's shape and promotes healthy and vigorous growth. It also prevents the plant from becoming too leggy or disproportionate. Use sharp and clean pruning tools to avoid damaging the plant's branches and spreading disease.
Propagation of Correa reflexa hybrid 'M'
Correa reflexa hybrid 'M' can be propagated using various methods:
1. Seed Propagation
This is the most common way to propagate Correa reflexa hybrid 'M'. To propagate using seeds:
- Sow seeds in well-draining soil mix.
- Keep the soil moist and warm, but not too wet.
- Germination can take between 2 to 4 weeks.
- Once the seedlings are big enough they can be transplanted.
2. Cuttings Propagation
Correa reflexa hybrid 'M' can be propagated using semi-ripe cuttings:
- Take a cutting from a healthy plant, making sure it's not too soft or too hard.
- Remove any leaves from the bottom half of the cutting.
- Dip the end of the cutting in rooting hormone.
- Place the cutting in well-draining soil mix.
- Keep the soil moist and warm, but not too wet.
- Roots should form in 4-8 weeks.
- Once the cuttings have rooted, they can be transplanted.
3. Grafting Propagation
Correa reflexa hybrid 'M' can also be propagated using grafting:
- Select a healthy rootstock and a scion from a healthy plant.
- Join the two parts and wrap them tightly.
- Keep the graft in a warm, humid place.
- The graft should take between 4-8 weeks to heal.
- Once the graft has healed, the plant can be transplanted.
Propagation of Correa reflexa hybrid 'M' is not difficult to do. It's important to handle plants carefully during propagation to ensure successful growth and healthy plants in the future.
Disease Management:
The Correa reflexa hybrid 'M' is generally resistant to diseases. However, it can be affected by some fungal diseases such as powdery mildew and root rot. To manage these diseases effectively, it is recommended to maintain good cultural practices such as watering only when necessary, providing adequate air circulation, and avoiding overhead watering. Applying fungicides may also be necessary in severe cases. It is essential to use appropriate fungicides and follow the recommended application rates.
Pest Management:
Some common pests that can affect the Correa reflexa hybrid 'M' are aphids, mealybugs, and spider mites. These pests can distort the shape of the plant and cause a decline in its health. To control these pests, it is recommended to regularly inspect the plants and remove any infected or infested parts. Additionally, it is beneficial to introduce natural predators such as ladybugs, lacewings, and predatory mites. In cases of severe infestation, insecticidal soaps or horticultural oils can be applied.
