When you look at Alocasia 'Borneo Giant' the only thing that will run through your mind is, Wow! It is not called Borneo Giant for nothing, this thing gets huge. The beast of an Alocasia can reach 10 feet at maturity with leaves 3 feet wide and 4 feet long. 'Borneo Giant' makes a killer-thriller plant set in the center of a mix combo.

 

Background

 

Alocasia plants have a broad native range. They grow indigenously in tropical rainforests, along streams and marshes in India, Southeast Asia and Southern China, through the South Pacific Islands to Eastern Australia. Specimens can grow up to 15’ tall with leaves growing 3’ wide by 4’ long.

 

Growth Requirements

Sun

Alocasia plants enjoy bright, indirect light. Avoid direct sun. This can burn the leaves.

 

Temperature/ Humidity 

This plant prefers warm temperatures, between 60 and 80 ºF is ideal. Alocasias will go dormant in temperatures below 60 ºF.

As a tropical plant Alocasia ‘Borneo Black’ prefers high humidity but will tolerate lower levels. To improve humidity use humidifiers or group plants together to create a greenhouse effect. 

 

Water

Water your Alocasia’s soil enough to keep it consistently moist but not soggy. This plant is particularly sensitive to root rot and will not tolerate overly moist soil.

 

Soil/Roots

Plant your Alocasia in moist, nutrient-rich, well-draining soil. These plants prefer a loose mix. Add pumice to improve drainage, and coco coir to improve water retention for these moisture loving plants. 

 

Flowering

Alocasia ‘Borneo Giant’ inflorescence features  a green spadix sheathed in a white spathe. 

Blooms occur during the spring and summer months, though this plant rarely flowers indoors.

 

Fertilization

These plants prefer nutrient rich soil, and will appreciate a boost during the growing season. Fertilize your Alocasia every two weeks with a balanced fertilizer, spring through fall. 

 

Propagation

Propagate Alocasia plants by division. Use clean, sharp shears to divide the plant into smaller pieces, making sure each piece has a few corms attached.

These plants can also be propagated by separating tubers. Gently uproot the plant, and divide the tuber from the parent plant. Plant it in soil, making sure the top of the tuber meets the soil surface. Keep soil warm and moist and provide plenty of humidity to encourage growth.

 

Health 

Diseases

Alocasia plants are not particularly susceptible pests though it is always a good idea to keep an eye out for common pests such as spider mites and aphids. 

These plants are more susceptible to bacterial and fungal infections. Keep an eye out for crown, stem, and root rot. Overwatering can increase the chances of these types of infections. Leaf spot disease is another concern. Avoid getting water directly onto the leaves.

 

Maintenance (pruning, legginess, repotting)

Prune away any unhealthy leaves. If your Alocasia is potted outside and hit by a cold snap, prune yellow leaves back to the base of the plant. 

Sometimes all of the leaves will be damaged. In this case, cut back the entire plant to its base, the crown of the plant will regenerate slowly. 

 

Toxicity

Extremely toxic to pets. This plant contains calcium oxalate crystals that cause swelling of the mouth, tongue, and upper respiratory. Keep out of reach of children and pets.

Speak to a doctor or veterinarian immediately if ingested. Severe cases of poisoning can be fatal.

The pot is not included. Root ball of the plant comes in a plastic poly bag, sealed to maintain moisture for the 3 days that the plant is in transit.

Height of the plants is measured from the base of the root ball.

No returns, refunds or exchanges

Fertilizer that I include as an option is an excellent choice for professional growers or nurseries if you grow plant in a pot. I personally use it for all my plants. It has polymer coating to allow slow release during 8-9 months evenly. You don't have to worry about repotting the plant for about 1 year or worry about burning plant with your regular over the counter fertilizer. You need about 3-4oz per 3 gal pot or 4-5oz per 5 gal pot.
