Indoor firs react very quickly to poor environmental conditions. The fact that a location is not well chosen or that the care is not correct is first shown by the needles. If these turn yellow or brown, this usually indicates a problem with too much moisture. How can brown needles be prevented on indoor fir trees?
How do I prevent brown needles on an indoor fir?
To prevent brown needles on an indoor fir, a cool location without direct sunlight should be chosen. Ensure regular spraying, sufficient humidity, moderate watering without waterlogging, and avoid drafts or frequent touching.
Causes of brown needles on indoor firs
If the needles of the indoor fir turn brown, various causes are conceivable:
- location too warm
- too much sun
- too dry air
- wet root ball
- Draft
Do not keep the indoor fir tree too warm
In the summer, the indoor fir likes it a little warmer. You can therefore care for them well in the flower window if it doesn't get warmer than 22 degrees there. However, indoor firs do not like direct sunlight, especially not at midday. Therefore, shade the plants if necessary.
In winter you have to look for a significantly cooler location for the indoor fir. In a heated living room, it reacts to the heat with brown or yellow needles or falling branches.
Increase humidity
A common problem that causes brown needles is low humidity. The warmer the ambient temperatures are, the higher the humidity must be.
Spray the indoor fir regularly with soft, stale water. Place bowls of water nearby to evaporate.
Water indoor fir trees with sensitivity
The root ball must never dry out completely so that the indoor fir does not develop brown needles. However, it tolerates waterlogging even less.
Water an indoor fir sparingly. Allow the surface of the soil to dry out before adding new water. Do the finger test!
There should never be water in the saucer or planter. It's a good idea to create drainage in the bottom of the pot when repotting so that the roots don't come into direct contact with water.
Draughts or frequent touching
Indoor firs react with discoloration of the needles even if the branches are touched frequently, for example because the plant is directly next to aisles or walkways. Place it in a protected place so that it doesn't get any drafts.
Tip
Household firs are non-toxic houseplants. However, they are not necessarily suitable for pet-friendly households as they do not tolerate frequent touching or nibbling of the branches by birds.
