Overview
Morella diversifolia (Adamson) Killick is an evergreen shrub that belongs to the Myricaceae family. It is native to South America, specifically in Brazil, Uruguay, and Argentina. The plant is commonly known as Buttonwood, Mastic tree, and Fern leaf Myrtle.Appearance
Buttonwood has a rounded habit and grows up to 10 meters in height. Its leaves are alternate, leathery, glossy, and range from oblong to elliptic, measuring about 3 to 7 cm long. The leaves' color varies from dark green to bronze and may turn reddish-brown in winter. The plant's flowers are inconspicuous and unisexual, with male and female ones in separate inflorescences. Upon pollination, the female flowers can produce small, round, nut-like fruits that turn from green to black and contain a single seed.Uses
Various parts of the Mastic tree have practical uses. The plant's leaves contain compounds that help repel insects, and trees are used in landscaping projects. The wood of Buttonwood is hard and used in making walking sticks, tool handles, furniture, and flooring. Another notable use of Mastic tree is in traditional medicine, where the plant's bark extracts are used to treat numerous ailments such as rheumatism, diarrhea, and wounds.Cultivation
The Mastic tree thrives in well-drained soil, and it prefers slightly acidic to neutral soil with good nutrition. The plant favors a sunny position, but it can also cope with some shade. It is tolerant of cold weather but may struggle in areas with prolonged frost. Buttonwood requires occasional watering during its early growth stage, and once established, it can survive dry spells. The plant can propagate via seeds or cuttings and can grow easily within its prescribed climatic condition.Growth Conditions for Morella diversifolia
Light: Morella diversifolia thrives in full sun to partial shade conditions. It can tolerate a wide range of light intensities, although it grows best in bright light conditions.
Temperature: The plant requires warm temperatures for optimal growth. The ideal temperature range for Morella diversifolia is between 20 and 30 degrees Celsius. It can tolerate high temperatures of up to 35 degrees Celsius, but growth may be stunted in such conditions.
Soil Type: Morella diversifolia prefers well-draining soils rich in organic matter. It can tolerate a wide range of soil pH levels but grows best in slightly acidic soils with a pH of between 5.5 and 6.5. The plant is also adaptable to different soil types, including loamy, sandy, and clay soils.
Soil Moisture: The plant requires moderate soil moisture levels for optimal growth. Overwatering can result in root rot, while underwatering can cause stunted growth and leaf drop. It is best to water the plant when the top inch of soil is dry.
Nutrient Requirements: Morella diversifolia is a low maintenance plant that requires minimal fertilization. A balanced fertilizer applied once a year in spring can enhance growth and promote foliage development. However, excessive fertilization can lead to leaf burn and other problems.
Cultivation methods
Morella diversifolia is commonly known as the Chinese bayberry. It is a subtropical fruit tree that requires a warm and humid climate to thrive. The tree prefers loamy, well-drained soil that is rich in organic matter. The best conditions for planting this tree are in areas with mild winters and wet summers, as it is intolerant to frost.
To cultivate Morella diversifolia, start by selecting a location that receives a lot of sunlight, and where the soil is well-drained. Prepare the planting beds by loosening the soil and adding compost or organic matter. Plant the tree at the same depth as it was in the container and water thoroughly.
Water the tree regularly and deeply to keep the soil consistently moist, but not waterlogged. Mulching around the base of the tree can help to conserve moisture and reduce weed growth.
Watering needs
The Chinese bayberry requires a consistent supply of water to thrive, especially during the hot and dry months. Water the tree deeply and regularly, making sure the water reaches the roots. Depending on the climate and the size of the tree, it may require watering every 2-3 days or even twice a week.
The tree is water-sensitive and can quickly develop root rot from waterlogged soils. To prevent this, ensure that the soil is well-drained and that the tree is not sitting in standing water.
Fertilization
Morella diversifolia requires regular fertilization to support optimal growth and fruiting. The tree will benefit from a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. Fertilize the tree three times during the growing season: in early spring, midsummer, and early fall.
Avoid fertilizing the tree in late fall or winter as it may cause the tree to continue to grow and not go dormant, which can make the plant more vulnerable to frost damage in colder climates.
Pruning
Pruning is essential for maintaining the shape and growth of the Chinese bayberry tree. The best time to prune the tree is during the dormant season in late fall or early winter. Prune out any damaged or diseased branches, as well as any branches that are rubbing against each other or growing in an awkward direction.
Keep in mind that the Chinese bayberry usually produces fruit on the previous year's growth. To encourage fruiting, prune the tree sparingly, as over-pruning can reduce fruit production.
Propagation of Morella diversifolia (Adamson) Killick
Morella diversifolia (Adamson) Killick, commonly known as the Pacific Bayberry, is a small tree or shrub found primarily on the west coast of North America. The plant is dioecious, meaning that there are separate male and female plants. It produces small, spherical, and purple fruits that are edible and have a waxy coating and a fragrant odor. The plant is propagated through seeds or vegetative means.
Propagation by seeds
Seeds can be obtained from mature fruits of the plant. It is best to obtain seeds from female plants to ensure that the seed produces a female plant. To propagate by seeds, the following steps should be taken:
- Scarify the seed coat.
- Soak the seeds for 24 hours in warm water (around 42°C).
- Plant the seeds about 1 cm deep in a mixture of peat and sand.
- Keep the soil moist and at a temperature of about 20°C.
- Germination may take anywhere from two weeks to two months.
- Once the seedlings have grown to a manageable size, they can be transplanted to their permanent location.
Propagation by Cuttings
Morella diversifolia can also be propagated by stem cuttings. The steps for propagation by this method are:
- Choose a healthy stem from a mature plant and cut it at a length of about 20 cm.
- Strip the leaves from the bottom two-thirds of the stem.
- Dip the cut end of the stem in rooting hormone.
- Plant the stem in a well-draining potting mixture.
- Water the stem and put the container in a warm, bright, and humid place.
- The plant should root in three to four weeks.
- Once the roots have developed, the plant can be transplanted to a permanent location.
Propagation of Morella diversifolia can be an effective way to get new plants. The propagation method used depends on the preference of the grower, the equipment, and the availability of materials.
