Fatsia japonica Plant - Japanese False Aralia for Indoors

Fatsia - Ornamental Fig indoor plant

The plant: Fatsia japonica - sometimes 'Ornamental Fig' - is basically a large evergreen hardy shrub, which can also be grown indoors as a spectacular houseplant. It has large, palmate leaves with upwards of seven lobes or fingers. Quite spectacular if well grown with individual leaves growing to 6 or 8 inches (15-20cm) across. The overall leaf has a slightly toothed margin.

To be seen at its best it will need a large pot rather than the small pot in which it has been grown and sold! The size of the pot will be the deciding factor as to its ultimate size.

Outdoors in a shrub area or as a stand-alone specimen, Fatsia japonica will grow to a large spreading shrub with height and spread of 4 feet (1.2m) or more. Indoors it will rarely reach those dimensions if ever. However it will still be cherished for its light green glossy foliage, and ability to grow in more or less any place that will give it the space it needs.

It rarely flowers as an indoors plant, but if you are lucky, then it will have unusual clusters of flowers held aloft of the foliage during early Autumn. If you do manage to get it into flower indoors, you will probably see the small black berries that follow the flowers.



Care of Fatsia japonica Aralia sieboldii

Its needs: The Japanese Fatsia requires strong light even some direct sun. The potting mix should be rich and fertile, well-draining but kept moist. Warmth and normal humidity preferred.

Keep the potting mix moist all year round, but do not allow the Fatsia to become waterlogged. On the other hand, if allowed to dry out too much, the leaves will warn you with their sad drooping appearance. Watering will soon rectify this.

In hot dry summers use a mist-spray on the foliage. Prune Fatsia to shape in spring, and pinch out leggy growth through the year. If left un-pruned the Japanese Fatsia will become a very large shrub. Can tolerate low temperatures but prefers normal range.

Good for: An easy, attractive evergreen plant that simply needs a little bit of space, which will be rewarded by giving you cooling elegance in a reasonably well lit corner.

Propagation Methods for Fatsia japonica and Aralia sieboldii

Key Differences

Fatsia japonica, also known as Japanese Aralia, is an evergreen shrub that produces large, glossy leaves and small white flowers. It's typically propagated by seeds, cuttings, or division.

Aralia sieboldii, or Siebold's Aralia, is also an evergreen shrub, known for its palmate leaves and umbels of white flowers. Similar to Fatsia japonica, it can be propagated by seeds or cuttings, but it's often propagated by root cuttings specifically.

Ideal Growing Conditions

Both plants prefer well-drained, fertile soil and a location with partial shade. They can tolerate full sun, but their leaves may scorch in intense heat.

Best Time to Propagate

The best time to propagate these plants is during the growing season, typically spring or early summer.

Tools and Techniques

Cuttings:
  1. Choose a healthy, mature stem and make a cut just below a leaf node.
  2. Remove lower leaves, leaving 2-3 leaves at the top.
  3. Dip the cut end in rooting hormone to promote root growth.
  4. Plant the cutting in a pot filled with a mix of perlite and peat moss.
  5. Keep the soil moist and place the pot in a bright, indirect light.
Seeds:
  1. Plant fresh seeds in a pot filled with seed compost.
  2. Cover lightly with compost or vermiculite.
  3. Keep the compost moist and place the pot in a warm, bright location.
  4. Germination should occur within a few weeks.
Root Cuttings (specifically for Aralia sieboldii):
  1. Dig up a portion of the plant's root system.
  2. Cut into sections, each about 2-4 inches long.
  3. Lay the cuttings horizontally in a tray filled with a mix of sand and compost.
  4. Cover lightly with more compost.
  5. Keep the compost moist and place the tray in a warm, bright location.
Possible Problems

Propagation might fail if the cuttings dry out, are taken from unhealthy plants, or if the growing medium doesn't drain well, leading to root rot. Make sure to keep the growing medium moist but not soggy, and use healthy, disease-free plant material.

Additional Insights and Tips

Adding a balanced organic or synthetic fertilizer to the growing medium can provide nutrients needed for root development. A slow-release granular fertilizer can be mixed into the growing medium prior to planting the cuttings or seeds.

Remember, propagation success depends on several factors, including the health of the parent plant, the timing of propagation, and the care given to the new plantings. With patience and attention to detail, you can successfully propagate these beautiful plants.

Fertilization and Nutritional Recommendations for Fatsia japonica and Aralia sieboldii

Nutritional Requirements and Soil Conditions Both Fatsia japonica and Aralia sieboldii prefer nutrient-rich, well-drained soil that is slightly acidic. They benefit from a balanced fertilizer that provides an equal ratio of Nitrogen (N), Phosphorus (P), and Potassium (K). Nitrogen promotes healthy leaf growth, Phosphorus aids in root development and flowering, and Potassium enhances overall plant vigor. Fertilizer Types and Recommendations
  • Organic Fertilizers: These are derived from plant, animal, or mineral resources, and include compost, manure, bone meal, and blood meal. They release nutrients slowly and improve soil structure but may not provide a balanced nutrient supply. For Fatsia japonica and Aralia sieboldii, compost or well-rotted manure can be beneficial.
  • Synthetic Fertilizers: These are chemically produced and provide nutrients rapidly. They come in various formulations, allowing for targeted fertilization. However, they can build up salts in the soil over time. A balanced synthetic fertilizer with a ratio like 10-10-10 could be suitable for these plants.
  • Slow-Release Fertilizers: These fertilizers release nutrients gradually over an extended period, reducing the risk of over-fertilization. They're available in both organic and synthetic forms.
Fertilizer Application Practices
  • Timing: The best time to fertilize is during the growing season, typically spring and summer.
  • Frequency: Apply fertilizer every two weeks during the growing season. In fall and winter, reduce fertilization as the plants' growth slows.
  • Dosage: Always follow the manufacturer's instructions for dosage. Over-fertilization can damage the plants and lead to nutrient imbalances.
  • Application: Mix the fertilizer into the top layer of soil or apply it as a liquid feed when watering.

To avoid issues like over-fertilization, always start with a smaller dose and increase only if the plant shows signs of nutrient deficiency, such as yellowing leaves or stunted growth. Regularly check the pH of your soil, as a pH that is too high or too low can prevent plants from absorbing nutrients effectively.



Tackling Common Problems with Fatsia japonica Aralia sieboldii

Pruning is a key part of caring for a Fatsia japonica Aralia sieboldii. To maintain the plant’s desired shape and size, pruning should be done regularly.
