Which begonias are suitable for planting in the garden?
ice begonias and leafy begonias are often used for planting in gardens. In principle, however, you can keep many begonias outdoors. You should only make sure that the temperatures are not too cold for the plants and that the begonias are not in the blazing sun or in the cold wind. Also choosing the right one
location for begonias plays a role in this.When can I put begonias outside again?
Place begonias in May after the Ice Saints back outside. In this way you avoid problems caused by late night frost. At the end of May, the temperatures at night no longer cool down enough to cause problems for your begonias. Once you've put the begonias outside, you should also regularly replant them fertilize or pay attention to a nutrient-rich substrate in the bed or balcony box of the begonias. The begonia care then takes a little more time.
Are there also hardy begonias?
With the Japanese slate and the Begonia panchtharensis you also have two hardy varieties available. These two plants come from shady forests and mountain regions respectively and do much better than others begonia varieties cope with cool to frosty temperatures. They are therefore particularly suitable if you are outdoors in cooler places plant begonias would like. However, these are exceptions.

Also note the humidity
Do you keep your begonia as a houseplant at a warm temperature all year round? Then you don't have to worry about frostbite. However, you should occasionally spray the plant with water from a spray bottle. This is how you ensure sufficient humidity.
