Avoid any direct sunlight
The best spot for your Iron Cross Begonia is somewhere with plenty of bright but indirect light. Too much intense light can harm their incredible foliage but insufficient light will make them leggy and they won’t be able to produce flowers.
The potting mix needs to dry out between waterings
Iron Cross Begonias are quite sensitive to overwatering so you want to make sure that the potting mix has nearly dried out before watering again. The best way to know if it’s time to water is by using a moisture meter.
A little humidity boost goes a long way
Whilst Iron Cross Begonias don’t need a super humid environment, a little boost every now and again will stop them drying up and becoming crispy around the edges. The best way to do this is through misting using a spray bottle or buying a humidifier.
They prefer cooler temperatures
It’s important that you don’t put your Iron Cross Begonia in a really warm spot in your home as they prefer slightly cooler temperatures.
Only feed in the spring and summer months
As with most houseplants, you only really want to fertilise your Iron Cross Begonia during the warmer sunnier months. We recommend using a water-soluble feed once a month during the growth period. Make sure to dilute more than recommended to avoid possible fertiliser burn.
Propagate your Iron Cross Begonia through division
Although you can propagate a Iron Cross Begonia through leaf cuttings, we recommend going for the division method as it is more successful.
To do this you need to separate the plant and root system into several smaller plants. Make sure each section has a good amount of roots attached before placing into fresh potting mix and resuming normal Iron Cross Begonia care!
