Even if the indoor cypress can tolerate a few degrees below zero for a short period of time, the plant is not winter hardy. You should therefore always keep them cool but frost-free. What you need to consider when overwintering indoor cypress trees.
Is a room cypress hardy?
Is the indoor cypress hardy? No, the indoor cypress can tolerate temperatures below zero for short periods, but it is not hardy. To overwinter, they should be placed in a bright, airy place with temperatures of 5 to 10 degrees and watered sparingly.
Winter indoor cypresses properly
- Bright but not sunny
- airy place
- Temperatures of 5 – 10 degrees
- water little
- do not fertilize
From spring to autumn, the indoor cypress prefers a bright, warm location, preferably on the terrace or balcony. At the latest when the temperatures drop below 10 degrees, it is time to bring the plant into the house or remove it from the windowsill in the living room.
Places for overwintering indoor cypresses
Since the indoor cypress is not hardy, the place to overwinter should not have frost temperatures. Temperatures should be between 5 and 10 degrees.
Bright hallway windows, bright basement windows or cool winter gardens are well suited for overwintering indoor cypresses. The main thing is that there is enough light, otherwise the plant will turn brown. Direct sunlight and temperatures above 10 degrees should be avoided at all costs.
Care for the non-hardy indoor cypress
The indoor cypress stopped growing in winter. It then needs significantly less water than in summer. Only water enough to prevent the substrate from drying out completely.
In fact, indoor cypresses don't need to be fertilized at all. Under no circumstances should you provide them with fertilizer between October and March.
Remove from winter quarters from March
As soon as the days get warmer, slowly get the room cypress used to its usual position on the windowsill. However, the plants are only allowed outdoors when there are guaranteed to be no more frost periods.
You should repot the indoor cypress every two years when you take it out of winter quarters. Place them in fresh substrate made from potting soil (€6.00 on Amazon), which you can mix with a little sand. Cactus soil is also good for indoor cypresses.
If you want to cut the plant, now is also the right time.
After repotting, you must not fertilize the room cypress as the new substrate contains sufficient nutrients.
Tip
Unfortunately, the shoots of indoor cypresses often turn brown. This is usually due to care errors or an incorrect location. The plants need a very bright place that does not receive too much direct sunlight.
