Red Ginger
Red ginger (Alpinia purpurata) is a beautiful and easy to care for houseplant. It is a tropical perennial which grows in clumps and produces showy, bright red flowers with a white spike, that make this plant an eye-catching specimen. The attractive dark green foliage is glossy in appearance expanding up to 2 feet (61 centimeters) long and 12 inches (30 centimeters) wide. Red ginger is an evergreen flower that can be grown outdoors in regions with a tropical climate like Hawaii. Red ginger is also a popular flower for flower arrangements because of its long-lasting blooms and glossy foliage.
The red ginger prefers well drained moist soil that is evenly moist but never soggy. During the growing season (spring to late summer) water frequently enough to keep the soil evenly moist but not soggy. During the winter, reduce watering to every 2 - 3 weeks, allowing the top layer of the soil to dry out before watering. Water the plant thoroughly when needed and then make sure to let the excess water drain out.
Red ginger prefers medium to bright indirect light with little or no direct sun. Don't place it in low light spots, as this can cause the health of the plant to decline. Make sure to also give it some direct sun in the morning or in the afternoon, for a few hours. If the leaves begin to yellow, the plant is receiving too much direct sun.
Red ginger prefers temperatures between 60 - 85 degrees Fahrenheit (15 - 29 degrees Celsius), with its ideal temperature sitting around 70 degrees Fahrenheit (21 degrees Celsius). If the temperature drops below this range, the plant is likely to suffer. Lower temperatures should be avoided, and if the climate is cooler, best to grow this tropical plant indoors.
To keep your red ginger healthy, the humidity levels should remain between 60 - 70%. To maintain humidity, mist the plant often or install a humidifier in the room where it is kept. You can also place the pot on a moist peat moss or create a tray of moist stones and gravel to help keep the humidity levels up.
Red ginger prefers a soil blend that retains moisture well yet still drains well and allows for air circulation. A good soil mix for this plant is a combination of peat moss, perlite, and sand. It’s best to mix together equal parts of these three components and ensure that the soil is well-draining.
Fertilize the red ginger plant with a balanced 10-10-10 fertilizer in the springtime, before the growing season. Apply a light feeding every other month from spring to late summer. Do not fertilize during the winter months, as the plant will not be actively growing. To help the plant grow and remain healthy, you can also use organic fertilizers, such as compost tea or fish emulsion.
Red ginger plants are prone to spider mites, scale, aphids, and thrips, which can be harmful to the plant. To prevent and get rid of these pests, check the plant weekly for any signs of infestation, use insecticidal soaps to treat, and use neem oil once a month to prevent invasion of these pests, as it is a completely safe and natural treatment. For spider mites, some home remedies include spraying the leaves of the plant with a mixture of water and dish soap or a mixture of water and rubbing alcohol to get rid of them.
It is important to repot red ginger every two to three years to keep the plant healthy and happy. When repotting, use a well-draining potting mix, such as a mixture of equal parts of perlite, peat moss, and potting soil. Repotting should be done in the springtime, just before the growing season. When repotting, make sure to loosen the root ball and add fresh potting mix to the pot. Once repotted, the soil should be kept consistently moist but not soggy.
The red ginger plant should only be lightly pruned. Pruning should only be done to remove any dead or damaged leaves or stems. In addition, pruning can help keep the plant in a more attractive shape. Pruning should be done in the spring just before the growing season so that the new growth is not affected.
Mulch, such as bark or pine needles, can be applied once a year to protect the plant in cold weather. Mulching can also help to keep the roots cool and retain moisture. Make sure not to over mulch, as this can cause root rot.
Red ginger can easily be propagated using either stem or root cuttings. For stem cuttings, take a tip cutting with 5-7 leaves and make sure to remove the bottom leaves to expose the growing nodes. Dip the cutting into a mixture of water and rooting hormone and plant into a pot with moist soil. You can also propagate from root cuttings by taking cuttings from the underground rhizomes and planting them into moist soil. Propagate in the springtime, just before the growing season.
Red ginger doesn’t require any additional support. Its stems are sturdy enough to stand up on their own, so it is unnecessary to stake the plant. However, if you would like to add a support, such as a trellis, you can do so, though it is not necessary.
Red ginger doesn’t need a rest period, but it is beneficial for the plant if it goes through one. A rest period helps to give the plant a chance to store up energy for the next season. To put your red ginger into a rest period, reduce watering and fertilizing but make sure the soil stays slightly moist. This rest period should last 4-6 weeks before the start of the growing season.
No, red ginger is not toxic to pets. It is safe for cats and dogs to be around if ingested. However, they should not eat the plant as it can cause minor irritation to the mouth and gastrointestinal tract.
