The dry environment found indoors often causes the tips and edges of houseplant leaves to yellow and brown off.
Identify the problem
The heated and air-conditioned atmosphere of indoor spaces is often very dry compared to the natural environment of most of the houseplants we grow indoors. These dry conditions, if not rectified, cause leaf tips and edges to yellow, brown off and die. Other causes may be under or over-watering.
To replicate the higher humidity of most houseplants natural environment it is important to keep the plants watered in an optimal manner and to mist the foliage of the plants frequently.
- Pot or re-pot houseplants in Gro-Sure Houseplant Potting Mix with Seramis® baked clay granules for water retention.
- Use the Gro-Sure Houseplant Watering Indicator to ensure the plants are watered when they need to be and not watered when they don't.
- Mist the plants regularly with Gro-Sure Houseplant Mist'n'Feed (or Orchid Mist'n'Feed as appropriate).
- Mist with water in between using Mist'n'Feed.
- Your houseplants will appreciate an occasional trip outdoors when it is temperate and raining; the natural rainfall on leaves washes and refreshes foliage.
- Potassium Deficiency can cause similar browning off of leaf edges. This is accompanied by yellowing of veins followed by wilting and the scorching moving inward.
