Why does my plant look limp

When indoor plants are thirsty

When buying a houseplant, the question of proper care usually arises. In addition to information on the location, such as sunny / shady or cool / warm, recommendations for optimal water supply are also important. Plant damage can often be traced back to casting errors.

There is no such thing as a “scheme F”. The water requirement depends on the specific requirements of the individual plant species and is also dependent on the location, humidity, temperature and growth period. A sure instinct is required here, because these factors must be viewed in context.

How much water the plant evaporates depends on the room temperature, the humidity and the size of the leaf area. The higher the temperature and the dry air, the more intense the evaporation. Even if the soil feels dry on top, there may still be enough moisture in the soil. It is best to check a little deeper first. Since water also transports the nutrients in the plant, a lack of water results in a lack of nutrients.

Caution, risk of drying out!

If leaves droop, curl up, turn yellow or dry up, a lack of water may be the cause. In this case, the plants will recover within a few hours after watering. They can be poured or dipped. When diving, the ball-dry plants are placed in the water with the pot up over the edge. The root ball is soaked when no more air bubbles rise. Only then take it out and let the excess water drip off. Diving is particularly useful for plants that are found in substrates with a high content of humus or peat or in coniferous soil, such as azaleas. Here the completely dried out soil does not absorb the moisture during normal watering, it simply rolls off.

Note the water temperature

Stale water, preferably room temperature, is best for watering. Tap or well water can be quite cold. Seven to twelve degrees Celsius is normal. Such a cold pour causes the floor temperature to drop sharply. "Cold feet" impair the root activity, so the plants can absorb less water and nutrients.

Correctly assess the water requirements of the plants

In these cases, you should water more often:

If the planter is made of unglazed clay, the permeable walls of the container also release water into the environment. If the plant is large and the pot is relatively small, the small volume of soil can only store small water reserves. This also applies if the plant has deeply rooted in the pot.

Plants need a lot of water and nutrients during the main growing season or when they are in bloom. High room temperatures and low air humidity stimulate evaporation. The demand for water increases. If the plant has large, soft leaves, it will also evaporate a lot of water. Species that live in a swampy biotope close to the groundwater, such as cyprus grass or papyrus, can withstand standing water in saucers or cachepots.

In these cases you should water less. Planters made of glazed clay or plastic do not allow moisture to escape into the environment. Small plants in large pots need less water. The larger volume of the soil serves as a water reservoir. This also applies to plants that have not yet rooted their pot.

Caution: freshly repotted plants do not need more, but less water until their roots have grown into the new habitat. This prevents waterlogging and the roots can quickly grow through the new substrate in search of water.

Plants need very little water even when they are resting. Numerous houseplants need a break to set flowers. If you keep them in vegetative growth by watering, they will not bloom. This applies, for example, to blood flower (elephant ear), Turmeric (Saffron root), Hippeastrum (Knight's Star), Clivien, columns, porcelain flower, Streptocarpus (Twist fruit), Christmas cacti, room calla or cylinder cleaner.

The plants evaporate less water at low room temperatures, as well as when the relative humidity is high. Plants with thick-fleshed leaves and shoots such as cacti and succulents are living water reservoirs that mostly come from areas with dry weather conditions.

If you familiarize yourself with the living conditions of the plants at their original home location, you can derive the conditions under which they also feel comfortable with us as indoor, container or balcony plants. You can tell by looking at them whether they get the care or not.
