๐ค๏ธ Growing conditions - the key to success
โ๏ธ Light - critical for colors!
Ideal type of light: bright and indirect - the lighting determines the intensity of the colors!
East/north window, filtered light
Direct sun will burn the leaves!
How does light affect?
- Bright light: bright, spectacular colors, good growth
- Low light: faded colors, slow growth
- Direct sun: burns! Leaves curl and brown
๐ง Irrigation - a delicate balance!
Key principle: Constant moisture but not wet! Begonia Rex is very susceptible to root rot.
Watering rules:
- Frequency: Once to twice a week (depending on conditions)
- Rule: When the top 1-2 cm is slightly dry
- Quantity: Water thoroughly until drained.
- Winter: Significantly reduced
Water at the base of the plant, emptying any excess.
Do not wet the leaves!
๐จ Moisture - the secret to success!
Requirement: High humidity - 50% or higher - this is the most critical requirement!
Begonia Rex comes from humid tropical forests. Brown leaf edges are a sure sign of low humidity!
How to increase humidity?
- ๐ซ๏ธ Humidifier: The best solution!
- ๐ชจ Pebble tray: Plant pot on pebbles with water (does not touch the water!)
- ๐ A bright bathroom: an ideal place
- ๐ฟ Plant grouping: creates a humid microclimate
- ๐ก Terrarium: A perfect environment for small begonias
๐ก๏ธ Temperature
Ideal range: 16-24ยฐC - likes it moderate , not too hot!
- โ Day: 21-26ยฐC
- ๐ Night: 15-18ยฐC (likes relatively cool nights)
- โ๏ธ Minimum: not below 10ยฐC
- ๐ฅ Maximum: up to 30ยฐC (with high humidity)
๐ชด Soil and pot
Soil type:
Light, airy and well-draining - Begonia Rex roots are very delicate!
- โ Soil for African violets (ideal!)
- โ Mixture: Peat + Perlite + Vermiculite
- โ Slightly acidic pH (5.7-6.4)
Choosing a flower pot:
- Shallow and wide: The rhizome grows wide, not deep!
- Drainage holes: Critical!
- Size: Not too large - roots are delicate
Transfer to a pot:
- When the rhizome reaches the edges of the pot
- Better in the spring
- A good opportunity to share!
๐งช Fertilization
Fertilization is important for colorful and healthy leaves!
Fertilization schedule:
Once every two weeks, diluted by half
Once a month
Full stop
Fertilizer type:
- Balanced liquid fertilizer: NPK 10-10-10
- Dilutions: Half the recommended concentration
- Nitrogen: Important for leaf development
โ๏ธ Pruning and cutting
Pruning:
- Remove yellow, dry, or damaged leaves.
- Prune long stems to encourage dense growth.
- Flowers can be pinched - diverts energy to the leaves
- Use clean tools!
Cutting - surprisingly easy!
Begonia Rex reproduces easily - even one-up!
๐ฟ Method 1: Leaf cuttings (most popular!)
- Choose a healthy, mature leaf.
- Cut the leaf into pieces - each with a vein.
- Place on moist soil (bottom side down)
- Cover with plastic wrap to create moisture.
- After 6-8 weeks, small plants will grow!
๐ Method 2: Rhizome division
- Remove the plant from the pot.
- Cut the rhizome into pieces (each with roots and leaves)
- Plant each part in a separate pot.
- Maintain high humidity
When: When transferring to a new pot
๐ง Common problems and solutions
