Coffeeberry is used in traditional medicine as an anti-inflammatory, antipyretic, and analgesic agent. It is also used as an astringent for treating diarrhea, dysentery, and hemorrhages. The plant is also beneficial in treating skin disorders such as rashes, eczema, and boils. It is also used in treating respiratory infections such as cough, asthma, and bronchitis. In addition, coffeeberry is utilized for its laxative properties.
General Appearance
The plant is an evergreen shrub or small tree with an erect, slender trunk that can reach up to 9 meters in height. The bark is brown and slightly rough. The leaves are simple, opposite, and dark green in color, growing to as long as 20 centimeters. The plant produces small white flowers that are densely clustered, followed by fleshy, purple-black fruit that look similar to coffee beans, hence the name. The fruit is approximately 1 centimeter in diameter and contains two seeds.
Light Requirements
Gonzalagunia spicata prefers an environment with bright, indirect sunlight. It can tolerate some shade, but too little light can stunt its growth. It is important to keep the plant away from direct sunlight as this can damage the leaves.
Temperature Requirements
The optimal temperature range for Gonzalagunia spicata is 21°C to 26°C. It can tolerate temperatures as low as 15°C, but prolonged exposure to temperatures below this range can damage the plant. High temperatures, above 30°C, can also harm the plant by causing leaf scorching and dehydration.
Soil Requirements
Good drainage is essential for Gonzalagunia spicata to thrive, as standing water can cause root rot. The soil should be well-draining and rich in nutrients with a pH range of 5.5 to 7.5. A mixture of sandy soil, perlite, and peat moss can provide good drainage and aeration for the plant's roots.
Cultivation
Gonzalagunia spicata (Lam.) G. Maza is a tropical plant that prefers warm temperatures and high humidity. This plant can be grown outdoors or indoors in containers. If you're planting it outdoors, make sure you choose a spot with well-drained soil, as this plant doesn't tolerate soggy soil.
When planting Gonzalagunia spicata, dig a hole twice as wide as the root ball and plant the stem at the same level as it was in the pot. Water the plant thoroughly after planting and keep the soil moist, but not waterlogged, until the plant is established.
Watering needs
Gonzalagunia spicata requires consistent watering, especially during dry weather. This plant can't tolerate drought, so it's essential to keep the soil evenly moist. However, make sure not to overwater it as it may cause root rot.
The frequency of watering may vary depending on various factors such as temperature, humidity, and soil type. So, it's recommended to check the soil's moisture level before watering. Use your finger to test the soil's dryness; if it feels dry to the touch, water the plant.
Fertilization
In the growing season, Gonzalagunia spicata requires regular fertilization to thrive. Use a balanced fertilizer every two weeks to ensure healthy growth.
You can use a slow-release granular fertilizer or a liquid fertilizer diluted to half strength. However, be cautious not to over-fertilize the plant, as it may cause damage to the roots.
Pruning
Pruning Gonzalagunia spicata is not necessary but can help keep the plant tidy and promote healthy growth. Prune the plant in early spring before the growing season to remove any damaged or dead branches.
To promote bushy growth, pinch off the tips of the stems. However, don't prune off more than one-third of the plant as it may stress the plant and reduce blooming.
Also, remove any suckers that emerge from the base of the plant to encourage the main stem's growth.
Propagation of Gonzalagunia spicata (Lam.) G. Maza
Gonzalagunia spicata (Lam.) G. Maza, commonly known as "Lancewood", is a small, slow-growing shrub or tree that is native to Central America and the Caribbean. It is mainly propagated by seeds and stem cuttings, which are easy to propagate and produce new plants.
Propagation by Seeds
Propagation by seeds is the most common method used to propagate Gonzalagunia spicata. Seeds are readily available from mature fruits that have fallen to the ground or from harvesting fruits from the tree. The best time to collect seeds is when the fruit is fully ripened, which is indicated by a change in color. The seeds must be extracted from the fruit, and then they should be properly dried and stored in a cool and dry place. Prior to planting, the seeds must be soaked in water overnight to facilitate germination.
To propagate Gonzalagunia spicata by seeds, fill a seed tray with a well-draining soil mix, and then sow the seeds at a depth of about 1 cm. Cover the tray with a clear plastic bag to maintain humidity and warmth. The seeds will typically germinate within 2-3 weeks, after which the plastic bag should be removed. The young plants should be kept in partial shade until they are mature enough to be transplanted to their permanent location.
Propagation by Stem Cuttings
Propagation by stem cuttings is another method used to propagate Gonzalagunia spicata. It is a more reliable method that produces identical plants. Stem cuttings should be taken in the spring or early summer, when the plant is in its active growth phase.
To propagate Gonzalagunia spicata by stem cuttings, select a healthy stem that is around 15-20 cm in length. Cut the stem just below a node using a sharp, sterilized knife or pruning shears. Remove the lower leaves, leaving only two or three leaves at the top. Dip the cut end of the stem in a rooting hormone, and then plant it in a well-draining soil mix. The cutting should be planted to a depth of about 5 cm and should be watered thoroughly.
The cutting should be kept in partial shade and should be misted regularly to maintain humidity. Roots will typically develop within 4-5 weeks, but should not be disturbed until they are well-established. Once the cutting has developed a strong root system, it can be transplanted to its permanent location.
