With their huge, glossy leaves in unique shapes and colors, alocasia plants are adored for bringing a tropical flair indoors. When starting these beauties from bulbs, many wonder – which way should my alocasia bulb be facing when I plant it?
Planting the bulb in the wrong orientation can lead to poor growth or even death of your precious new plant. Understanding the right way to situate the bulb will get your alocasia off to a vigorous start.
How Do I Know Which End of the Alocasia Bulb Should Be Up?
Alocasia bulbs resemble small teardrop or garlic cloves, with a rounded side and more pointed end. There are a few clues to tell which side should be planted facing upwards
-
The pointed tip is where new leaves and stems will emerge from the bulb, so this end should face up.
-
Often small offshoots or nubs protrude from the pointed end – these will develop into new growth.
-
The flatter wider base is where roots will sprout from, so this end should go down into the soil.
-
If sprouts or roots are already visible, orient the bulb so they grow up and down accordingly
-
When in doubt, plant sideways – the plant’s internal cues will direct its growth upward.
Always handle bulbs gently to avoid damaging the tender new growth. Washing off any debris reveals the shape and growing tips clearly.
Will It Damage or Kill the Plant If Planted Upside Down?
Unfortunately planting the alocasia bulb upside down or sideways can prevent it from developing properly. With its growing tip buried, lack of light and air circulation can lead to:
- Rotting of the bulb
- Decline or death of the plant
- Very stunted growth if any sprouts do emerge
Getting the bulb position correct provides the best chance for lush, vigorous growth of your new alocasia.
Follow These Steps for Planting Success
-
Select a potting container with drainage holes, about 2 inches wider than the bulb.
-
Use a well-draining potting mix enriched with compost or worm castings.
-
Identify pointed growing end of the bulb and face upwards in the container.
-
Bury bulb halfway into the soil, with growing tip above the surface.
-
Gently firm soil around bulb and water thoroughly after planting.
-
Place in warm area with indirect light to encourage new growth.
-
Once sprouted, move to bright location without direct sun exposure.
-
Keep soil consistently moist but not saturated as the plant establishes.
With proper orientation and care, the alocasia bulb will soon reward you with upright growth and lush green leaves. Enjoy watching your new plant unfurl its tropical splendor!
