Aralia plants, belonging to the Araliaceae family, are renowned for their ornate foliage and architectural presence. These plants, originating from various regions across Asia and the Americas, offer a multitude of species and cultivars, each with unique characteristics. This guide delves into their origins, popular cultivars, and provides detailed care instructions to help you successfully cultivate these striking plants.
With its lush green foliage and ease of care, the Balfour aralia is a popular houseplant choice. However, like all plants, it can fall victim to rot if proper care isn’t taken. In this comprehensive guide, I’ll cover the causes of rot in Balfour aralia plants and provide actionable solutions to prevent this detrimental plant disease.
What is Rot?
Rot is the breakdown of plant tissues caused by fungal or bacterial infections. The affected areas become mushy and discolored as the cells decompose. Rot typically starts in the roots but can spread upwards into stems and leaves. If left unchecked, rot will kill the plant by destroying its vascular system.
What Causes Rot in Balfour Aralia Plants?
Overwatering
Excessive soil moisture is the leading cause of rot When roots are constantly wet, oxygen is displaced from pore spaces This creates an environment ideal for fungal and bacterial growth. Roots literally rot away.
Poor Drainage
Insufficient drainage has a similar effect as overwatering. Waterlogged soil prevents air from reaching roots. Without oxygen, pathogens thrive and rot sets in.
Root Damage
Injuries to roots from repotting insects, or improper handling can create entry points for fungi and bacteria. Damaged tissues are more prone to infection.
Temperature Extremes
Very cold or very hot conditions place stress on plants. This renders them more susceptible to pathogens and more likely to develop rot.
Preventing Rot in Balfour Aralia Plants
Allow Soil to Dry Between Waterings
Only water when the top inch of soil is dry. This prevents excessive moisture around the roots. For most homes, watering every 7-14 days works well.
Improve Drainage
Repot in a container with drainage holes using a fast-draining potting mix amended with perlite or orchid bark. Terracotta pots also improve drainage.
Provide Warm Temperatures
Balfour aralia thrives in average home temperatures of 65-80°F. Keep away from cold drafts. Adequate warmth reduces stress and rot risk.
Increase Air Circulation
Good airflow around the plant inhibits fungal and bacterial growth while oxygenating the soil. Rotate the plant or use a small fan to keep air moving.
Allow Soil to Dry After Repotting
When transitioning to a larger pot, wait 7-10 days before resuming a normal watering regimen. This gives any damaged roots time to heal.
Sterilize Tools
Disinfect shears, knives, and other gardening tools with isopropyl alcohol before using them on your Balfour aralia. This prevents spreading pathogens.
Apply Fungicide After Pruning
If pruning away diseased or dead tissue, treat the cut areas with copper fungicide. This helps protect the wounds against rot-causing infection.
What If My Plant Already Has Rot?
If you catch it early, you may be able to save a Balfour aralia with mild rot by:
- Pruning off all affected roots and stems
- Repotting in fresh, sterile potting mix
- Treating with fungicide drench
- Resuming proper watering and care
However, extensive rot often necessitates replacing the plant entirely. Focus efforts on disease prevention.
Common Questions about Rot in Balfour Aralia Plants
How often should I water my Balfour aralia plant?
Water only when the top inch of soil is dry, typically every 7-14 days. Balfour aralia is prone to rot with overwatering.
What potting mix is best for Balfour aralia plants?
Use a loose, fast-draining potting mix amended with ingredients like perlite, orchid bark, or coconut coir to improve drainage and aeration.
Where should I place my Balfour aralia plant?
Balfour aralia thrives in bright, indirect light away from cold drafts. Bathrooms and kitchens can be too dark and humid, increasing rot risk.
Can I propagate a healthy plant from one with rot?
It’s not advisable to propagate from a rot-infected plant as the pathogens could spread to cuttings. Always take cuttings from healthy mother plants.
Conclusion
While susceptible to rot if overwatered or kept in cold, stagnant conditions, a Balfour aralia plant can thrive for years with attentive care focused on ample warmth, air circulation, and proper moisture levels. Check plants regularly for signs of disease and take prompt preventative action at the first hints of trouble. A rot-free Balfour aralia will reward you with lush, vibrant foliage bringing life to any indoor space.

This item ships in a grower pot.
Pruning helps maintain the desired shape and size, especially for the bushier cultivars. Trim back leggy growth and remove any dead or yellowing leaves.
Aralias are susceptible to pests like spider mites, mealybugs, and aphids. Regular inspections and prompt treatment with insecticidal soap or neem oil are crucial. Good air circulation helps prevent fungal diseases.
Repot your aralia every 2-3 years or when it becomes root-bound. Choose a pot only slightly larger than the previous one to avoid excessive soil moisture.
Aralias can be propagated from stem cuttings or seeds. For stem cuttings, use a rooting hormone and provide consistent humidity and warmth for best results.
In colder climates, bring outdoor aralias indoors or provide adequate protection. Reduce watering and stop fertilizing during this dormant period.
Variegated aralias need more light than their green counterparts to maintain their unique coloration.
Scientific Name: Polyscias fruticosa
Common Names: Ming Aralia, Polynesian Aralia
Overview: The Ming Aralia (Polyscias fruticosa) is an exquisite and graceful houseplant, cherished for its finely divided, feathery foliage. This elegant plant showcases layers of rich green leaves, creating a lush, dense canopy atop slender, woody stems. Its unique, oriental look adds a sophisticated, natural beauty to any indoor environment. Typically reaching a height of 6-8 feet when grown indoors, it can be easily pruned to maintain a smaller, more compact shape, suiting various spaces from office corners to cozy living rooms. Ming Aralia thrives in bright, indirect light and prefers a consistently moist soil environment, without being waterlogged. Regular misting helps to maintain the humidity levels it loves. It’s a great choice for plant enthusiasts looking for a slightly challenging yet rewarding plant.
Prefers warmer temperatures and higher humidity. Its delicate leaves are prone to browning if conditions are not optimal.

Being more cold-tolerant, it’s well-suited for outdoor gardens in temperate regions. It prefers shadier conditions and can tolerate lower humidity levels.
Origins and Diversity of the Aralia
Aralias, sometimes referred to as Spikenards, originate from a wide range of climatic conditions, from the cold mountains of Japan to the tropical regions of Central and South America. This diversity has led to a variety of species, each adapted to its native habitat. Popular species include the Polyscias scutellaria (Shield Aralia), Ming Aralia (Polyscias fruticosa), and the Fatsia japonica (Japanese Aralia), to name a few.
To thrive, aralias require specific conditions that mimic their natural habitat.
Aralias prefer bright, indirect light. Direct sunlight can scorch their leaves, while too little light may cause leggy growth. A north-facing window is ideal for indoor plants.
Most aralia species enjoy a temperate climate, with temperatures ranging from 60-85°F (15-29°C). They also prefer high humidity, which can be achieved through regular misting, using a humidifier, or placing the plant on a pebble tray with water.
Watering requirements vary by species, but most aralias prefer consistently moist soil. Overwatering can lead to root rot, so it’s crucial to let the topsoil dry out slightly between waterings.
A well-draining potting mix is essential. You can create a suitable mix by combining regular potting soil with perlite or orchid bark to improve drainage.
Feed your aralia with a balanced, water-soluble fertilizer every month during the growing season. Reduce feeding in winter when the plant’s growth naturally slows.
