Japanese spikenard
The Japanese Spikenard (Aralia cordata) is a hardy perennial shrub native to Japan and China. This impressive, low-maintenance plant grows to an average of 2-5 feet tall, making it the perfect species for smaller gardens and landscapes. With its intricate, leafy fronds, bronze-tinted trunk and miniature yellow flowers, Japanese Spikenard makes a statement all season long. The plant's berries boast an almost black color and are high in edible iron, making them an excellent supplement for Iron deficiency. Japanese Spikenard is a truly amazing and rewarding plant to grow and maintain.
The Japanese Spikenard should be watered when the soil is mostly dry to the touch. Keeping the soil moist between watering should help promote healthy growth. To ensure that you are not overwatering, utilize a soil moisture meter. If the soil is wet, wait until it is mostly dry to the touch before watering.
Japanese Spikenard enjoys direct sunlight and partial shade. The plant is sure to do best in a spot that receives 2-3 hours of direct sunlight each day. However, it is important to note that this species prefers cooler daytime temperatures above 50°F and should not be placed in a spot that receives direct sunlight during the hottest part of the day.
This species favors an average temperature range of 50-75°F (10-24°C). When temperatures drop or rise above this range, take extra precautions to protect the plant, including providing additional sunlight, shelter, water, and fertilizer.
The Japanese Spikenard loves a moist, humid environment with an average humidity of above seventy percent. To achieve a suitable environment, utilize a humidifier or mist the foliage of the plants regularly with a spray bottle. If the humidity drops below 40%, risks of powdery mildew and leaf-tip burn increase.
For optimal growth, Japanese Spikenard should be planted in soil that is well-draining and nutrient rich. An ideal pH range for the Japanese Spikenard is 6.0-7.2. Additionally, it is important to remember that these plants prefer a soil that is slightly acidic. You can ensure the soil has enough acidity by adding coffee grounds or a fertilizer that is designed specifically for acid-loving plants.
The Japanese Spikenard, like all plants, requires regular fertilization. Fertilizing should be done with a balanced fertilizer according to the manufacturer’s instructions. It is important to note that a balanced fertilizer should contain equal amounts of nitrogen, potassium, and phosphorus. Additionally, a fertilizer specifically designed for acid-loving plants should be used to promote healthy growth.
Japanese Spikenard is susceptible to many pests, such as aphids, mealybugs, and spider mites. To get rid of aphids, spray them with a mixture of five tablespoons of dish soap in one gallon of water. Mealybugs and spider mites can be isolated and taken care of with neem oil or insecticidal soaps. To prevent pests from appearing, the Japanese Spikenard should be inspected often and any possible infestations should be caught immediately.
When repotting Japanese Spikenard, it is best to do so every two or three years in a container that is approximately two inches larger than the previous one. Repotting should occur in the spring, as the plant is just beginning to show signs of growth. The container should contain fast-draining soil containing equal amounts of potting soil and peat moss for optimal growth.
Prune sparingly, if necessary. If the plant begins to become too full or unmanageable, trim off any dead, diseased or damaged fronds. Take caution not to over prune as Japanese Spikenard are slow to produce new foliage. It is best to prune during late winter and early spring.
Mulching or spreading of organic compost around the base of the Japanese Spikenard can help keep the soil moist and the roots cool. Additionally, mulching helps to act as a barrier between the roots of the plant and the extreme temperatures of the soil. The ideal mulch should consist of peat moss, sand, and compost.
Propagation of Japanese Spikenard can be done in several ways. Seeds can be collected from the plant and planted for propagation. Additionally, the plant can be propagated through cuttings. The cuttings should be taken from the plant’s stems and placed in potting soil. To ensure that the actively growing plant has enough nutrition, supplemental fertilization should be done throughout the season.
For best results, Japanese Spikenard should be supported by a stake or trellis. This will help ensure that the plants remain upright and support the main structure of the plants as they grow.
The Japanese Spikenard requires a slow phase of dormancy during the winter season. During this time, the amount of watering and fertilizer should be reduced. The rest period will promote healthy new growth and fruiting of the plant when the warmer seasons arrive.
The Japanese Spikenard is reportedly listed as non-toxic to both humans and animals making it a great addition to any home or garden.
