๐ค๏ธ Growing conditions - the key to success
โ๏ธ Light
Ideal light type: Medium to bright, filtered - very flexible!
North/East window, interior of the house, office
Strong direct sun (you will burn!)
How does light affect?
- Bright light: fast growth, bright colors
- Low light: slower growth, greener leaves (less diversity)
- Direct sun: brown spots/burns on the leaves!
๐ก Tip: The plant tends to grow towards the light - turn it occasionally for even growth!
๐ง Irrigation - the most important principle
The golden rule: Dieffenbachia prefers relatively dry soil - it's better to have too little than too much!
Watering frequency:
- Summer: Once a week (approximately)
- Winter: once a week or two
- Rule: When the top 2 cm of the soil is dry to the touch
Irrigation method:
- Water thoroughly until water comes out of the drainage holes.
- Empty standing water! Do not leave it in the dish.
- Let the soil dry out between bags.
๐จ Humidity
Requirement: Medium humidity - 40-60% (normal home conditions are usually sufficient!)
How to improve humidity (optional):
- ๐ฟ Spraying leaves in the summer (recommended!)
- ๐ชจ Pebble tray with water
- ๐ฟ Grouping with other plants
๐ก๏ธ Temperature
Ideal range: 18-27ยฐC (normal home temperature - perfect!)
- โ Normal home/office temperature is suitable
- โ๏ธ Minimum: not below 15ยฐC
- โ ๏ธ Keep away from air conditioners and cold air currents
- โ ๏ธ Keep away from radiators and heat sources
๐ชด Soil and pot
Soil type:
Well-draining soil - this is most important!
- โ Standard houseplant soil
- โ Perlite can be added for better drainage
- โ Slightly acidic pH (5.5-6.5)
Choosing a flower pot:
- Drainage holes: A must!
- Size: Depending on the plant, not too large
Transfer to a pot:
- Every 1-2 years or when it becomes crowded
- Better in spring
- A pot 2-3 cm larger
๐งช Fertilization
Dieffenbachia doesn't require much fertilizer - less is more!
Fertilization schedule:
Once every two weeks-a month
Once a month
Break or minimum
Fertilizer type:
- Balanced liquid fertilizer for houseplants
- Dilutions: Half the recommended concentration
โ๏ธ Pruning and cutting
Pruning:
- Remove yellow or damaged leaves with a low cut.
- If the plant becomes tall and "leggy" - the top can be pruned.
- Pruning encourages denser growth
- Use clean, sharp tools!
Cutting - the easiest way!
Method 1: Top cutting
- Cut the top with 3-4 leaves.
- Place in water or moist soil
- Roots will develop within a few weeks.
- Plant when the roots are a few centimeters long.
Method 2: Stem cutting
- Cut stem sections 5-7 cm long
- Place horizontally on moist soil (bury halfway)
- Leaves and roots will grow from the "joints"
division:
If there are several stems, the plant can be divided when transplanting. Make sure each part has roots.
๐ง Common problems and solutions
๐ก Yellowing leaves
Possible reasons:
- Overwatering - the most common!
- Natural aging (lower leaves)
- Lack of light
- Temperature too low
Solution: Reduce watering, check drainage
๐ค Brown leaf edges
Possible reasons:
- Overfertilization
- Soil/air too dry
- Irregular watering
- Salts in water
Solution: Spray leaves, use filtered water
๐ฅ Falling leaves
Possible reasons:
- Lack of irrigation
- Overwatering (root rot)
- Lighting is too low
- cold
Solution: Check soil moisture and adjust watering
๐ Spots on the leaves
Possible reasons:
- Brown spots: sunburn
- Dark spots with a halo: fungal disease
- Central rings: bacterial disease
Solution: Remove infected leaves, improve ventilation
๐ฑ "Reglony" plant
Reason: Lack of light - the plant takes longer to search for light.
Solution: Move to a brighter location, trim the top.
This is a natural phenomenon - the plant will lose lower leaves over time.
๐ชด Base decay
Reason: Overwatering + Poor Drainage
Solution: Stop watering, move to new, drier soil, remove rotten parts
๐ Common pests
Thin webs, yellow dots.
Solution: Increase moisture, rinse with water
White lumps like wool.
Solution: Alcohol + cloth, neem oil
Hard brown lumps.
Solution: Manual removal, potassium soap
Small green insects, honey.
Solution: Potassium soap, rinsing

โ Frequently Asked Questions
This is normal! Dieffenbachia naturally loses lower leaves as it grows. Simply remove them.
Yes, but rare at home. The flowers are similar to spathiphyllum - not very impressive. Most people grow it for the leaves.
Relatively fast! In good light, it can produce a new leaf every few weeks during the growing season.
Yes! Dieffenbachia adapts to artificial lighting, but growth will be slower and the leaves will be less colorful.
Prune! Cut off the top, and the plant will branch and become denser. The cutting can be planted separately.
Yes! This is "gutting" - the plant excretes excess water in the morning. If there are a lot of salts in the soil, the drops can burn the tips of the leaves.
๐ Interesting facts
The plant is considered to bring luck and ward off evil spirits! Combine with rosemary and chili pepper in a lucky urn.
