Mums, also known as Chrysanthemums, are beautiful flowering plants that are commonly seen in gardens during the fall season. However, did you know that you can also grow mum plants indoors? With a little care and attention, you can enjoy the vibrant colors of mums all year round. In this article, we will guide you through the steps to successfully grow mum plants indoors.

Choosing the Right Mum Variety

The first step in growing mum plants indoors is to choose the right variety. There are numerous mum varieties available, each with its unique characteristics and growth requirements. Some popular indoor mum varieties include “Cushion Mums,” which have compact growth habits, and “Spider Mums,” which have long, spidery petals.

When selecting a mum variety for indoor cultivation, consider factors such as the size of your space and the amount of sunlight it receives. If you have limited space, opt for compact varieties that will not outgrow their containers. Additionally, choose a variety that thrives in the amount of sunlight available in your home.

Providing Adequate Sunlight

Mum plants require at least six hours of direct sunlight each day to thrive. When growing them indoors, it is essential to place them in a location that receives ample sunlight. Choose a south-facing window or a spot near a bright artificial light source.

If your indoor space lacks sufficient natural light, you may consider using grow lights. LED grow lights are highly recommended as they provide the necessary light spectrum for plant growth without generating excessive heat.

Maintaining Optimal Temperature and Humidity

Mum plants prefer cool temperatures ranging between 60°F to 70°F (15°C to 21°C). Avoid placing them near heat sources such as radiators or vents, as excessive heat can cause wilting and damage to the plant.

Maintaining adequate humidity levels is also crucial for mum plants. Indoor environments tend to be drier, especially during winter when heating systems are in use. To increase humidity around your mum plants, you can place a tray of water near them or use a humidifier.

Choosing the Right Pot and Soil

Selecting the right pot and soil is essential for the healthy growth of mum plants indoors. Choose a pot with drainage holes to prevent waterlogging, as excessive moisture can lead to root rot. The pot should be large enough to accommodate the root system and allow for proper growth.

For soil, choose a well-draining potting mix that is rich in organic matter. Avoid using garden soil, as it may contain pests or diseases that can harm your mum plant. Adding perlite or vermiculite to the potting mix can improve drainage and aeration.

Watering and Fertilizing

Proper watering is crucial for the health of your mum plant. Water the plant thoroughly until water drains out from the bottom of the pot, and then allow the top inch of soil to dry out before watering again. Overwatering can lead to root rot, while underwatering can cause wilting and stunted growth.

Fertilize your mum plant every two weeks during the growing season using a balanced liquid fertilizer. Follow the instructions on the fertilizer label for dosage and application. Avoid overfertilizing, as it can lead to nutrient burn and damage to the plant.

Pruning and Pinching

Pruning and pinching are important techniques for maintaining compact and bushy mum plants indoors. Pinching involves removing the top inch of new growth using your fingers or scissors. This encourages branching and results in a fuller plant.

Regularly prune your mum plant by removing any dead or damaged leaves or flowers. This not only enhances the appearance of the plant but also improves air circulation, reducing the risk of diseases.

Dealing with Pests and Diseases

Mum plants are susceptible to certain pests and diseases, even when grown indoors. Common pests that can infest mum plants include aphids, spider mites, and whiteflies. Monitor your plants regularly and take immediate action if you notice any signs of infestation. Insecticidal soaps or neem oil can be effective in controlling these pests.

Diseases such as powdery mildew and botrytis blight can also affect mum plants. Proper air circulation, avoiding overhead watering, and maintaining optimal humidity levels can help prevent these diseases. If your plant does get infected, remove the affected parts and treat with appropriate fungicides.

Enjoying the Blooms

With proper care and attention, your indoor mum plant will reward you with beautiful blooms. Remember to deadhead spent flowers regularly to encourage continuous blooming. Trim off any withered or yellow leaves to maintain the plant’s appearance.

Indoor mum plants can brighten up any space with their vibrant colors and lovely fragrance. Whether you choose to grow them in pots or hanging baskets, these steps will help you successfully cultivate mum plants indoors. So go ahead and bring a touch of autumn into your home all year round with these delightful flowers!
