Begonia hybrid 'Cosmic Mist'

BEGONIA CULTIVATION

 

Begonias grow from temperate to tropical climates with the vast majority of species being from tropical and sub tropical climates. Apart from a few exemptions most begonias require even temperatures, humidity, good air circulation and a well drained potting medium. Begonias will not tolerate wet feet and soggy potting mediums. They require bright indirect light

 

Begonias will quickly rot if given too much moisture and quickly dry out with out enough humidity. It can be a tricky balance. Finding the right species for the right situation is important.

 

Begonias will grow happily as indoor plants and terrarium plants if their conditions are met.

 

Their soil should be allowed to dry out between waterings. Begonias are similar to succulents in that requirement. It is important to keep up humidity between waterings which can be achieved through a light mist in the mornings. Keep your begonias away from direct sunlight and hot windows as their delicate foliage can burn easily.

 

My go to potting medium is a 50/50 mix of a good quality potting mix and perlite with commercial quality slow release fertiliser added to the mix at the manufacturers recommendation. Soil Ph is best kept neutral to slightly acidic but some species will require more specific Ph modifications so it is best to do research on individual species.

 

Begonias respond well to foliar and liquid feeding with seaweed and fish based solutions. Apply as to the manufacturers instructions. Begonias always respond well to being repotted and divided which should be done at least every 12 months.

 

Airflow is crucial to good cultivation. Consider placing your begonias in a situation where they receive some air movement and terrariums may need a small fan.

 

If you get the cultivation spot on then begonias are relatively pest free plants. If you notice signs of fungal disease then have a look at your watering schedule and your airflow. Mancozeb is useful agains stubborn fungal issues. Pests are similar to those that plague other indoor plants and are best treated early on to avoid infestations.
