How to Grow Dahlia Plant Indoors

Dahlia plants are popular for their vibrant blooms and are often grown in gardens. However, not everyone has a garden or the space to grow them outdoors. Fortunately, you can still enjoy these beautiful flowers by growing them indoors. In this article, we will guide you on how to grow dahlia plants indoors.

Choose the Right Variety of Dahlia Plant

Before you start growing dahlias indoors, it is essential to choose the right variety of dahlia plant. Some varieties are better suited for indoor growing than others. Dwarf dahlias are ideal for indoor growing as they do not require much space and produce smaller blooms that are perfect for indoor arrangements.

Preparing the Pot and Soil

Choose a pot that is at least 12 inches in diameter and has good drainage holes. Fill the pot with a well-draining potting mix that is rich in organic matter. Add perlite or sand to the potting mix to improve drainage.

Planting Dahlia Tubers

Dahlia plants grow from tubers, which are similar to bulbs. To plant dahlia tubers, dig a hole in the center of the potting mix that is deep enough to accommodate the tuber. Place the tuber in the hole with the eye facing up and cover it with soil. Water the soil thoroughly.

Providing Optimal Growing Conditions

Dahlia plants require bright light to grow and thrive. Place your pot in a sunny location where it receives at least six hours of direct sunlight each day. If you do not have access to natural sunlight, you can use artificial lights such as grow lights.

Water your dahlia plant regularly, keeping the soil moist but not waterlogged. Overwatering can cause root rot, which can be fatal to your plant.

Fertilize your dahlia plant every two weeks during the growing season with a balanced fertilizer. This will provide your plant with the necessary nutrients to produce healthy blooms.

Pinching and Pruning

To encourage bushier growth and more blooms, pinch the top of your dahlia plant when it reaches a height of about 6 inches. This will stimulate the growth of lateral branches. Continue to pinch the tips of the branches as they grow to promote bushy growth.

Prune your dahlia plant regularly by removing any dead or damaged leaves and flowers. This will keep your plant looking neat and tidy and also encourage new growth.

Storing Dahlia Tubers

At the end of the growing season, you can store your dahlia tubers for next year’s planting. Dig up the tubers and brush off any excess soil. Allow them to dry in a warm, dry location for a few days before storing them in a cool, dry place for the winter.
