Monstera Obliqua Bolivia
The Monstera obliqua Bolivia has the least amount of fenestrations in all varieties and proliferates the least often.
Origin Of The Monstera Obliqua
The Monstera originated from the tropical regions of Central and South America, in areas like Panama and Hawaii. The first Monstera plants were discovered in 1693 by French Botanist Charles Plumier.
In 1975, a famous researcher from Miami, Monroe Birdsey, discovered the Monstera obliqua in Peru. It was confirmed two years later, in 1977, by Dr. Michael Madison, who collected 17 Monstera obliqua plants.
The Monstera Obliqua are found primarily in South America and some regions of Central America. These Monstera species are native to Panam, Costa Rica, and the Amazon. Wild obliques have been collected over 710 times, far lower than most due to their extreme rarity.
Care Guidelines
Monstera obliqua is an extremely delicate plant that is tough to grow. It is essential to have the appropriate knowledge of the requirements of the obliqua plant to ensure healthy growth. Below are some care guidelines and requirements for the Monstera obliqua.
Light
The Monstera obliqua is a sunlight-loving plant; the more light it has, the better it will grow. However, the plant leaves do not have large surface areas to absorb light, so too much direct sunlight can burn the plant’s foliage and harm the thin leaves, so it is vital to keep it out of direct lighting.
It can withstand up to three hours of direct sunlight. Due to their Tropical habitat, the Monstera obliqua are accustomed to high levels of humidity that protect them from direct sunlight. The morning light is less harsh and perfect for the obliqua.
Providing your Monstera obliqua plant with eight to ten hours of indirect light from a window is plentiful.
The leaves start to wilt and turn yellow if it receives little sunlight. The leaves begin to curl and dry up if it gets too much sunlight. It is essential to find the right balance.
If you prefer to keep your plant away from sunlight altogether, LED lamps can be a good alternative. Choose an LED lamp that allows you to change the intensity of the light.
Watering
Generally, watering the Monstera obliqua once or twice a week during the summers and once every two weeks during the winters is enough.
Another general rule for watering the plant is to wait until the top layer of the soil is dry. You can check this by touching the soil surface with your finger.
If your plant is not getting enough water, the leaves will start browning and crippling. If you are overwatering your plant, the leaves get waterlogged and start turning yellow, and in extreme cases, the stems will collapse.
Humidity
As a tropical plant, the Monstera obliqua is accustomed to high humidity levels (between 60% to 80%).
If the humidity levels are low, the leaves will curl and wilt. Keeping the plant away from direct heat, open windows, and air conditioners is essential. The plant can stay healthy even in low humidity levels, but appropriate humidity levels are needed for perfect growth.
Misting the leaves frequently or putting them near the bathroom or the kitchen is fine. You could also use a humidifier to maintain the humidity levels required by the plant. You could also place a moist pebble tray underneath the plant or place the plant with other houseplants.
Fertilizer
Although not necessarily a requirement, fertilizers are a great way of taking good care of the Monstera plant. Unlike most plants, the Monstera obliqua is a slow grower and requires less fertilizer. Feeding the obliqua plant every two weeks during the growing period is enough.
Alternatively, it can be beneficial to fertilize it once a month in small amounts during the spring and summer. In the winter, avoid fertilizing the plant to prevent salt buildup that can damage the roots.
Fertilizing the Monstera should be done if you want the plant to grow quicker (albeit still slower than most) or if you notice the leaves beginning to droop.
A 20-20-20 liquid fertilizer mixed with a gallon of water is the optimum choice for feeding. Add the fertilizer a few centimeters above the base of the pot. Fertilize it again every few weeks.
Most potting mixes come with added fertilizers, so it is essential to look at the soil mix before deciding on fertilizers.
Soil Mix Recommendations
Proper soil is essential for the growth of the Monstera obliqua plant. The plant’s delicate roots can be crushed or restricted by dense, dry, or clogged soil. A potting mix that provides the required nutrients, better aeration, and prevents fungal or bacterial infections is optimal for the plant.
A peat-based soil mix is a good choice for good care of the plant as peat stores water, allowing the plant to absorb as much as possible.
Coconut coir is the soil mix is an alternative to peat as it has water-holding capabilities and retains moisture, removing excess moisture from the roots.
Another alternative is loam. Loam soil creates air holes that allow roots to spread without resistance and absorb nutrients.
The optimum pH of the soil for the Monstera obliqua is slightly acidic, with a pH level between 5 and 7.
Pot Types and Pot Sizes
The Monstera obliqua, when bought, usually comes in a small plastic pot. The small pots help allow the roots to settle, but soon the roots start to grow and break out of the pot. When choosing the type and size of pot for your obliqua plant, you need to choose one that’s big enough for the plants to grow while having appropriate drainage.
Pot Type
You can choose many different types of pots to grow Monstera obliqua.
Plastic pots are often the pots that these plants come in. They are an excellent choice for water retention, especially if the plant is placed in a dry environment.
Clay pots are often used for their water-retention properties that don’t dry out quickly, allowing you to water your plant minimally and preventing fungal rot.
Ceramic pots are often the go-to for aesthetics as they come in different designs and make your home look elegant. However, these pots are often expensive and have poor drainage, ultimately harming the plant.
Pot Size
In the early juvenile stages, the Monstera obliqua does not demand a large spot size, so a small pot of around twenty centimeters in diameter can work just fine.
As the plant grows, the pot needs to be changed for a bigger one. An adult Monstera obliqua would demand a larger pot of around ninety centimeters.
It is important to choose an appropriately sized pot as a pot that is too small will damage the roots and cause the soil to dry out. A large pot will not hold moisture, causing moisture to accumulate on the roots, leading to fungal diseases such as root rot.
Repotting
The Monstera obliqua is a slow-growing plant and only needs to be repotted once every few months when it is in its growing period. A mature plant will only need to be repotted once every few years.
A good indicator that your plant needs to be repotted is when you see roots growing out of the pot’s drainage holes. Another method is to check the soil to see if there is enough space for the roots to grow.
When repotting the plant, choose a pot at least five centimeters larger in diameter than the previous. To avoid damage to the plant, avoid repotting the plants in the winter.
Place the plant in the pot and add soil carefully to avoid damaging the roots.
Once you’ve repotted the plant, add water to the soil and continue growing it.
Ideal Growing Zones
The geographical range of the obliqua plants is mainly localized to central and south America. The plant should only be grown in USDA hardiness zones 9b to 11.
The minimum average temperature for these zones is around 25°F to 30°F and consists of some parts of Florida, South Carolina, New Mexico, Hawaii, and Louisiana.
Propagation
You can propagate Monstera Obliqua in two ways:
Propagation from Cutting
To propagate the plant from its cuttings, you need to look for the nodes on the branches. These nodes are areas from where new branches grow. Often, these nodes would start to grow roots themselves. If you notice a node with roots, cut the stem from the node, including the roots.
Place the stem cuttings in a pot, cover with peat or loam soil mix, and water the pot generously. In a few weeks, the cutting will start to develop roots.
Propagation from Stolon
Stolons are stems that grow out of the soil and don’t grow leaves. They are highly polypotent and can grow new roots without being removed from the plant.
Stolons don’t appear often and can take their time. Once they do, cover the stolons with soil in the same pot, and they will start to generate roots. They require high humidity, which is tough to do without damaging the original plant.
Hence, you can cut the stolon from the plant and place it in another pot. You can create a humid environment using a glass or a jar.
