However, providing the proper soil is key to keeping your Balfour Aralia healthy and thriving. In this article, we’ll explore everything you need to know about choosing the ideal potting mix for your Balfour Aralia plant
Why Soil Matters
Soil is the foundation of your plant’s growth. It anchors the roots, retains moisture, and provides essential nutrients. The right soil encourages strong root development and gives your Balfour Aralia the best chance to flourish. Conversely, poor quality or inappropriate soil can lead to stunted growth, leaf discoloration, and declining health.
When selecting soil, you need to consider factors like drainage, aeration, and nutrient content. The optimal soil will have the right balance to meet the specific needs of your Balfour Aralia. Keep reading to learn exactly what that entails.
Well-Draining Yet Moisture Retentive
Balfour Aralias require a porous soil that drains well while still retaining some moisture. Dense compacted soils that stay soggy after watering are a recipe for root rot. Alternatively a soil that dries out too rapidly will cause the leaves to brown, shrivel and drop.
To achieve the ideal moisture balance, incorporate materials like perlite, pumice, or horticultural charcoal. These porous substances help aerate the soil and prevent compaction. Some moisture-retentive additions like peat moss or coconut coir are also beneficial. Aim for a mix that dries slightly between waterings but never becomes dusty dry.
Nutrient-Rich With Organic Matter
Balfour Aralias are hungry plants with a vigorous growth habit. They thrive in nutritious soil amended with organic matter. Things like compost, worm castings, or well-rotted manure provide a slow release of macros and micronutrients.
A soil devoid of nutrients often results in stunted plants with yellowing foliage and sparse growth. On the flip side, over-fertilization can burn the roots and leaves. An organic, nutrient-dense base is the best place to start. You can always supplement with a balanced liquid fertilizer as needed.
The Right pH Balance
Testing your soil’s pH is recommended to ensure it falls in the ideal range for Balfour Aralias. A pH between 6.0-7.5 provides the optimal balance of nutrients availability. If the reading falls outside of this range, amendments can modify the pH level.
Lime raises pH, while sulfur lowers it. Getting the pH within the target range prevents many issues tied to nutrient deficiencies. For indoor plants, premixed potting soils usually have a pH within the acceptable parameters.
Options for Potting Mixes
Now that we’ve covered the criteria, let’s look at suitable potting mixes for your Balfour Aralia:
Commercial Potting Mix
A general houseplant potting mix works well for Balfour Aralias. Opt for a formula containing peat moss, perlite, vermiculite and organic fertilizers. Many commercial mixes provide an ideal balance of drainage and moisture retention.
Custom Soil Blends
You can create a customized potting mix to perfectly meet your plant’s needs. DIY recipes allow you to control the ingredients and ratios. A sample blend might contain 2 parts potting soil, 1 part perlite, 1 part peat and 1 part orchid bark.
Soilless Mixes
Soilless mediums like coco coir avoid issues with poor drainage, compaction and gnats. Coco coir offers moisture retention while still aerating the roots. Combine coco coir with perlite or bark for even better results.
Potting Soil with Fertilizer
If you want to simplify matters, use a potting mix blended with time-release fertilizer. These eliminate the guesswork regarding nutrition. Just beware of excessive mineral salt buildup over time. Periodic flushing of the soil prevents this.
Key Takeaways
- Well-draining, aerated soil prevents soggy, compacted roots
- Moisture-retentive additions like peat moss or coconut coir
- Nutrient-rich organic matter encourages vigorous growth
- Ideal pH range between 6.0-7.5

No matter what medium you choose, inspect the roots when repotting. Trim any that are blackened or mushy. Sterilize pots and tools to prevent disease transmission. Repotting into fresh soil at least every 2-3 years reestablishes nutrients.
With the proper soil foundation, your Balfour Aralia will continue growing into a spectacular, healthy specimen. Paying attention to its potting mix needs results in a lush, vibrant plant that brightens your indoor garden.
Frequently Asked Questions
How often should I water my Balfour Aralia?
Water your Balfour Aralia whenever the top inch or so of soil becomes dry. This is typically every 7-10 days but can vary based on factors like light exposure, temperature and humidity. Let the soil dry out somewhat between waterings.
What’s the best fertilizer for a Balfour Aralia?
Use a balanced houseplant fertilizer, applying at half strength every 2-4 weeks during the growing season. Look for equal ratios of nitrogen, phosphorous and potassium. Organic options like fish emulsion or kelp extract work well.
Should I mist my Balfour Aralia?
Misting can help raise the humidity around your plant. However, it doesn’t significantly affect soil moisture or penetrate to the roots. Focus more on proper watering and creating a humid environment. Group plants together or use a humidifier.
Can Balfour Aralias grow in a terrarium?
The humid environment of a terrarium suits a Balfour Aralia perfectly. Use shallow pots and an open-air design for adequate airflow. Monitor moisture closely in this setting and allow the top layer of soil to dry periodically.
What are the best pots for a Balfour Aralia?
Choose containers with ample drainage holes. Plastic, glazed ceramic and terra cotta pots all work well. Make sure pots are not too large to prevent soggy soil. Go up just one size when repotting.
Should I put gravel or rocks in the bottom of the pot?
This outdated practice can actually increase moisture retention. It’s better to focus on well-draining soil. Adding a layer of gravel doesn’t improve drainage through the root ball.
Can Balfour Aralias grow outdoors?
Balfour Aralias make excellent outdoor plants year round in zones 10-11. Provide partial shade, frequent watering and well-draining soil. Move the plant indoors if temperatures drop below 60°F.
Why are the leaves turning brown or yellow?
Issues like low humidity, overwatering, poor drainage and pests can cause leaf discoloration. Brown leaf tips often signal dry air while yellowing typically indicates overwatering or lack of nutrients. Check all aspects of care to remedy.
How can I raise the humidity?
Group plants together, use a humidifier, place pots on pebble trays of water, or create a terrarium to increase humidity. Misting provides temporary benefits. Ensuring proper watering and soil moisture also helps.
Conclusion
From drainage and aeration to moisture retention and nutrients, choosing the ideal soil is one of the most important factors in growing a healthy Balfour Aralia. Follow the tips above to provide this tropical beauty with everything it needs to thrive indoors. Paying attention to its soil needs will be amply rewarded with vigorous, long-lasting plants.
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.
