Foliage
There are several types of foliage in Hoyas, which vary depending on the species. The leaves can be simple or compound, green or variegated, smooth or hairy, and can have varied shapes. Some Hoyas have thick, leathery leaves, while others have thinner, delicate leaves. Some species have narrow, elongated leaves, while others have wider, rounded leaves. Generally, Hoyas have green leaves, but some species have variegated white, cream, or yellow leaves.
Watering
Hoyas are drought tolerant plants, so it is important not to water them too frequently. It is best to let them dry out slightly between waterings. In general, it is recommended to water Hoyas once a week or every two weeks, depending on the heat and humidity of the air. It is important not to let the roots soak in water, as this can lead to root rot. It is also important not to water the foliage, as this can lead to fungal diseases. It is best to water the plant from the bottom.
It should be noted that the water needs of Hoyas can vary depending on the season, the size of the plant and its location. It is therefore important to regularly monitor the condition of the plant and adjust watering accordingly.
Brightness
Hoyas generally prefer indirect light to partial shade, but some species can tolerate higher light levels. It is important not to expose Hoyas to direct sunlight, as this can cause leaf burn and faded colors.
Hoyas that have variegated white or cream leaves may require a little more light to maintain their coloring, while species with dark green leaves can tolerate lower light levels.
It is important to note that the light requirements of Hoyas can vary depending on the species and age of the plant. It is therefore important to regularly monitor the condition of the plant and adjust it accordingly.
Minimum temperature
Hoyas are tropical plants and prefer warm, high temperatures. Most species of Hoyas can tolerate minimum temperatures of 10 to 15 degrees Celsius (50 to 59 degrees Fahrenheit). It is important to note that colder temperatures can damage leaves and slow plant growth. It is therefore best to keep Hoyas at temperatures as warm as possible, avoiding temperatures below 10 degrees Celsius (50 degrees Fahrenheit).
It is important to note that the temperature needs of Hoyas can vary depending on the species and age of the plant. It is therefore important to regularly monitor the condition of the plant and adjust it accordingly.
Soil type
It is possible to use a soil mixture for Hoya that includes pine bark, pumice, coconut fiber, activated charcoal, peat moss and earthworm casting. However, it is important to note that these ingredients should be used in small quantities to avoid insufficient drainage or excessive water accumulation.
Pine bark can help maintain good drainage, aeration of the soil and nourish the soil as it decomposes quietly. Pumice can also improve drainage, capture micronutrients and increase soil porosity. Coir can help maintain moisture in the soil, but it should be used in small quantities. Activated carbon can help root development thanks to the released carbon. It also helps eliminate rot and fungus. Peat moss can help maintain moisture in the soil but should be used in small quantities. Earthworm burrows can add nutrients and minerals to the soil, but they should be used in small amounts.
Fertilization
Fertilizing Hoyas is generally necessary to maintain healthy, vigorous growth of the plant. It is recommended to use a balanced fertilizer (5-5-5 or similar) diluted to half the recommended strength and apply it every 4 to 6 weeks during the growing season (spring and summer). It is important not to over fertilize, as this can cause yellow leaves and slowed growth. It is also important not to fertilize Hoyas during the dormant season (fall and winter), as this can cause damage to the plant.
It should be noted that the fertilization needs of Hoyas can vary depending on the species and the age of the plant. It is therefore important to regularly monitor the condition of the plant and adjust it accordingly. It is also important to follow the manufacturer's instructions regarding the dilution and frequency of application of the fertilizer used.
Bloom
The flowering of Hoyas is often one of the most attractive aspects of these plants. Hoya flowers are usually large, fragrant, and can be different colors, such as white, pink, red, or yellow. Flowering can occur at different times of the year depending on the species, but is generally most abundant in summer or autumn.
Hoyas can be difficult to achieve flowering because they need optimal growing conditions to flower. Hoyas need sufficient light, warm temperatures and good drainage to bloom. They also need good nutrition, regular watering and periodic rest to bloom.
Some Hoyas do not flower easily in domestic cultivation, but rather in outdoor situations. It is therefore important to find out about the specific needs of the plant before ordering it.
Spread
The hoya cutting technique is quite simple and can be done using different methods. Here are some general steps for cutting a hoya:
-
Choose a healthy, flexible stem from the parent plant. It is best to choose a stem that has nodes close to the base, as this indicates that the stem is mature enough for cuttings.
-
Cut the stem at a 45-degree angle just below a node with a clean, disinfected knife. Remove lower leaves from the stem to reduce water evaporation.
-
Place the cut stem in a mixture of sand and peat moss or in water. Make sure the leaves do not touch the substrate or water to avoid rot.
-
Cover the stem with a plastic bag or cloche to keep humidity high and prevent drafts.
-
Place the cutting in a shaded area and keep the substrate moist. It may take several months for roots to appear.
-
Once roots appear, remove the cloche or plastic bag and place the cutting in full sun. Water regularly and fertilize once a month to encourage growth.
It is important to note that some hoya species may be more difficult to take cuttings than others. It is therefore important to check the needs of the specific species before starting.
Dormancy
Most hoya species have a dormant or resting period, usually in winter or early spring. During this time, plant growth slows significantly and it is important to reduce watering to avoid root rot problems. It is also important not to fertilize during this time, as this can damage the roots.
In general, it is best to keep hoyas in low light and cooler temperatures during the dormant period. This may mean placing them in a cooler room in the house or placing them outside during the winter months, climate permitting.
It is important to note that specific dormancy requirements vary from species to species. It is therefore important to check the needs of the specific species before starting.
Toxicity
There isn't much information on the toxicity of hoyas. Some species of hoya can cause mild skin irritation if handled frequently, but there is no evidence that hoyas are toxic to humans or pets. However, it is still important to keep plants out of reach of children and pets to avoid any risk of disease or accidental ingestion. It is also best not to ingest the plant parts, as this may cause digestive problems.
