How to Grow Gloxinias

Often gifted at housewarmings, Gloxinias make spectacular houseplants during winter months. However, they will easily make the move from indoors to outdoors in the summer, especially if you start growing the tubers in late February to early March. Gloxinias boast large, velvety leaves and their abundant cup-shaped blossoms in rich hues make for a perfect table centerpiece at summer BBQs.

How do I start to grow my Gloxinia?

Start with a container at least 4-6” in diameter with a drain hole and saucer. Gloxinias grow to 20 cm (8”) in height and width. Try grouping 2-3 tubers in larger containers for more impact. Plant the tubers hollow side up, ½ inch deep, in a moistened well-draining potting soil mix.

How much should I water my tubers?

Water sparingly to keep the soil moist until the first leaves begin to grow. Gloxinias are sensitive to cold water, so lukewarm water is best. Water only when the soil feels dry and avoid watering gloxinia leaves directly. Try placing the pot in a shallow saucer of water and let it sit for about an hour.

Should I fertilize my gloxinias?

Once leaves appear, begin feeding Gloxinia with half-strength bloom fertilizer when watering. Gradually increase fertilizer strength as your Gloxinia grows.

How long will my Gloxinia bloom for?

The blooming cycle begins about four months after planting and lasts as long as 3-4 months. Start tubers in early March and you will see flowers by July and into fall.

Where do Gloxinia like to be outdoors?

Sheltered locations that receive partial shade in the afternoon are perfect for Gloxinia to thrive in.

How long will they last in my garden?

You can enjoy them all summer, just remember to bring them back inside before the first frost.
