Lantanas can be kept indoors as houseplants during the winter months. However, it is important to note that this is not the best way to overwinter these plants, as they are perennials and naturally go dormant during the colder months.
When bringing lantanas indoors, it is crucial to provide them with the right conditions to survive and thrive. Here are some key points to consider:
1. Light: Lantanas require ample sunlight to thrive, so it is important to place them in a well-lit area. Ideally, they should receive at least 6-8 hours of direct sunlight each day. If you don’t have a suitable location with sufficient sunlight, you can supplement it with artificial grow lights.
2. Temperature: Lantanas are native to warmer climates and prefer temperatures between 60-85°F (15-29°C). It is important to keep them away from drafts and cold windows during the winter months. Avoid placing them near heating vents or radiators, as this can cause the air to become too dry.
3. Humidity: Lantanas prefer higher humidity levels, so it is a good idea to mist the foliage regularly or place a tray filled with water near the plant to increase humidity. Avoid misting the flowers directly, as this can cause them to rot.
4. Watering: Lantanas should be watered thoroughly, allowing the soil to dry out slightly between waterings. Overwatering can lead to root rot, so it is important to ensure proper drainage in the pot. Avoid letting the plant sit in standing water.
5. Fertilization: While lantanas do not require heavy fertilization, you can feed them with a balanced, water-soluble fertilizer once a month during the growing season. Be sure to follow the instructions on the fertilizer packaging for the correct dosage.
6. Pruning: Regular pruning is important for lantanas to maintain their shape and encourage new growth. You can prune them back by about one-third in early spring, before they are brought outdoors again. This will help promote bushier growth and more abundant flowering.
7. Pest control: Indoors, lantanas are less susceptible to pests compared to outdoor plants. However, it is still important to keep an eye out for common houseplant pests such as aphids, mealybugs, and spider mites. If any infestations occur, treat them promptly with organic or chemical insecticides.
It’s worth noting that while lantanas can be kept indoors during the winter, they may not flower as prolifically as they would outdoors. This is because the limited daylight hours in winter can affect their blooming cycle. Therefore, it is often recommended to allow lantanas to go dormant during the winter months.
To do this, you can gradually reduce watering and allow the plant to dry out. Once the foliage starts to die back, prune the plant back to a manageable size and move it to a cool, dark location such as a basement or garage. During this dormant period, avoid fertilizing and watering the plant until springtime when you can gradually reintroduce it to light and resume regular care.
While lantanas can be kept indoors as houseplants during the winter, it is not the optimal way to overwinter them. Allowing the plant to go dormant in a cool, dark location is a better option for their long-term health and survival. By providing the right conditions and care, you can enjoy the beauty of lantanas both indoors and outdoors throughout the year.
