Growing Conditions and Care Tips for Air Plants
Air plants are fascinating plants that can grow luxuriantly without soil and can produce bright flowers, and they have high ornamental value, which makes them a great choice for many people growing indoor plants. Below we will take a detailed look at air plant growing conditions and air plant care tips.
The Living Habits of Air Plants
Air plants do not need to be planted in soil, nor do they need to be grown in water. They are a special plant that can grow with just misting. The fine hairs on the leaf surface can absorb water vapor and nitrogen compounds from the air, and they can live very well without special care, though they grow quite slowly.
Growing environment: Air plants grow in tropical and subtropical rainforests or arid mountain areas at elevations of 100 m to 5000 m, attached to tree trunks, rocks, or cliff crevices, with a few growing on cacti. Their biggest difference from terrestrial plants is that their roots do not have the function of absorbing water and nutrients; they only serve to anchor the plant and carry out a small amount of air exchange. Nutrients and water are absorbed through the silvery-gray hairy scales on the leaf surface. They basically cannot survive when grown in water or soil.
Most air plant varieties are native to the tropical or subtropical regions of Central and South America, growing on flat ground or in high mountain areas at elevations of 1000 m to 3000 m, where there is little rain, strong sunlight, and great temperature variation, but where there is misty moisture all year round. This unique ecological environment gives air plants their distinctive habits. In their places of origin, these plants mostly grow attached to cacti, rock walls, rotten wood, utility poles, eaves, and other places, so when growing them, no flowerpot or soil is needed. They can be hung up or stuck to dead wood, walls, and other objects, or placed in other shallow containers. If potted, coarse gravel, stones, and similar materials can be used as the growing medium to anchor the plant.
Air plants are tolerant of drought and strong light, and their root systems are very poorly developed. Some varieties even have no roots, and even if they do have roots, these can only serve to anchor the plant and cannot absorb water and nutrients. So how do air plants absorb water? On careful observation, you will find that there are many small white scales on the leaf surface. These scales are mostly shield-shaped and sunken, and moisture in the air or rainwater is captured by the stomata in the sunken areas and then penetrates into the plant body through the gaps between thin-walled cells. Usually, the stomata in these scales are half-closed during the day when the temperature is higher and the air is relatively dry, in order to reduce water evaporation; at night, when the temperature drops and air humidity increases, they open completely to absorb moisture from the air.
Most air plant varieties grow in dry environments, while a small number prefer humid environments. Varieties that grow in rainforest climates or other relatively moist, shaded areas have broad, green leaves and produce larger flowers, but the flower colors are relatively plain. They live as epiphytes on another plant or tree trunk, and over time they gradually grow roots to anchor the plant itself. They can reproduce the next generation by seeds or offsets. Varieties from dry areas have a completely different appearance. Their plants are smaller, with needle-like or hard leaves, and usually grow in a whole clustered clump to reduce water evaporation. They rely on the large number of hairs on the leaf surface to absorb rainwater, dew, mist, and nutrients. Because they survive by absorbing moisture from the air through the leaf surface, their bodies have made many changes, including water-storage tissue, complex absorbent hairs, reduced leaf number, root degeneration, smaller body size, and increased seed quantity. Most of the more advanced air plants look grayish-white because the leaf surface is covered with hairs, which serve to reflect light, avoid sunburn, and prevent water evaporation. The more exposed they are to sunlight, the denser their hairs are.
The biggest difference between these plants and ordinary plants is that they have no root system, and the water and nutrients they need are completely absorbed through the stomata on the leaf surface. If planted in soil or water, they instead cannot survive. Their flowers and leaves are both very special. The leaves have evolved into special forms, including water-storage tissue, scale hairs on the leaves, reduced leaf number, and root degeneration. They have extremely strong adaptability to adverse conditions and can tolerate drought, light, wind, shade, heat, and cold; they need no pot, no soil, and do not breed mosquitoes; they are plants that grow attached to tree trunks, rock walls, and even cacti.
Air plants are drought-tolerant aerial species in the genus Tillandsia of the pineapple family, and are perennial epiphytic or aerial herbaceous plants.
Cultivation Methods
The main cultivation containers for air plants include shells, stones, dead wood, tree fern boards, rattan baskets, and so on. For fixing, they can be tied with wire or rope, or attached to the container with all-purpose glue or hot-melt glue, or cultivated by hanging, tied with copper wire or rope and suspended in the air.
Temperature
Air plants are native to the highlands of Central and South America and can tolerate low temperatures of 5°C. The suitable growing temperature is 15°C-25°C. When above 25 degrees, ventilation should be strengthened and humidity increased.
Watering
Air plants can be misted with a spray bottle 2-3 times per week, and in dry seasons they should be misted once a day. When misting, spray until the leaf surface is completely wet, and be careful not to let water accumulate in the leaf center. If too much water is sprayed, the plant can be turned upside down to let the excess water flow out.
Light
Varieties with grayer leaves and more, thicker, harder white scales need stronger light; varieties with greener leaves and fewer, softer scales are more shade-tolerant. When cultivated indoors, they should be placed in a place with bright light. If light is insufficient, the plant will become leggy and weak.
Fertilizing
Under artificial cultivation conditions, Hyponex or monopotassium phosphate plus urea diluted 1000 times with water can be sprayed once a week, or the plant can be soaked in a fertilizer solution diluted 3000-5000 times for 1-2 hours. Fertilizing can be stopped in winter and during the flowering period.
Precautions
1. Strictly speaking, it is not necessarily required to keep the temperature above 5 degrees in winter. If there is good light during the day, even below 0 is no problem;
2. Also, I must remind everyone that you absolutely must not grow it in a tank. Air plants need a very large amount of air circulation and will rot in a stuffy tank. If the weather is too dry, just soak the plant in water for about an hour, then shake off the water on the leaves. Also, when the leaves are wet, absolutely do not put it in the sun, or the leaves will be sunburned. All air plants are relatively drought-tolerant, and there will absolutely be no problem if they are not given water for a few days;
3. Varieties in the silver-leaf group are even more drought-tolerant than others, so please appropriately reduce watering frequency to avoid rot;
Most air plants do not have as high a demand for air humidity as imagined, and even in their places of origin, air humidity is not high during the day when there is light, but at night, because the temperature drop causes a temperature difference, water vapor condenses on the plant to form water, which is then absorbed by the leaves. As long as you grasp this characteristic, you can adjust the water supply according to different cultivation environments. Generally speaking, air plants only need to be given water at night. The specific amount depends on the environment and the condition of the plant, and growers need to control it flexibly according to the situation.
Air plants have extremely strong stress resistance. When they look slightly dry, their resistance can reach its peak. Plants that look tender have very low resistance and are prone to disease and rot at the slightest disturbance. Therefore, in cultivation, it is better to let the plant be slightly dry so that it can maintain a healthy state.
