Water and Light Requirements of Indoor Plants

Two of the basic fundamentals of growing indoor plants are meeting their light and water requirements. If these needs aren’t correct, the plant will fail to thrive. Some plants are forgiving, even in the wrong conditions, and will continue to grow happily, but many have very specific needs.

As a rule, succulents are one of the hardiest plants, they love full sun and can handle drought conditions as they store water in their fleshy tissues. Other plants need consistently moist soil but not soggy. When the soil is saturated, the pore space is filled up which deprives the roots of oxygen.

I have excluded the frequency of watering because it will vary from season to season, outside temperature and location. Obviously, a houseplant in Australia during summer will require more water than a houseplant in England during winter. It is also important to note that not all plants will follow the same water regimen. It is far more effective to check the soil of each plant individually and water as required.

Soil substrate is also important for each individual plant. Some prefer rich soil, others well-draining. If you are at all unsure, check with your local garden centre.

Potting mix

Low/moderate: Able to tolerate lower-light positions, but prefers bright, indirect light.

Bright/indirect: A location that receives diffuse bright light, and morning light, avoid afternoon sun which is too strong. Can be placed close to a bright window, but out of direct light.

Full sun: Likes to grow in full sun, with lots of direct rays.

Most plants are happy in bright but indirect light. This means the plant is placed near a window or glass door, but not so close that the sun rays hit the foliage.
