Understanding Caladium Bulbs

Caladiums are tropical plants that are grown for their colorful foliage. They belong to the aroid family and are native to South America. Caladium bulbs, also known as tubers or firm tubers, are the storage organs of the plant that contain all the nutrients required for the plant to grow and thrive.

Caladium bulbs are available in a variety of colors and cultivars, and they can be planted in outdoor gardens or indoor containers. They are typically planted in the spring and summer months when the soil is warm and moist.

When purchasing caladium bulbs, it is important to choose bulbs that are firm and free of any soft spots or blemishes. The size of the bulb does not necessarily determine the size of the plant, but larger bulbs tend to produce larger leaves.

Caladium bulbs should be planted about 4 to 6 inches deep and spaced about 10 to 15 cm apart. They prefer well-drained soil that is rich in organic matter and kept moist.

It is important to note that caladium bulbs are sensitive to cold temperatures and frost. They should not be planted until all threat of frost has passed. In Houston, the best time to plant caladium bulbs is in late April or early May when the soil is warm and the temperatures are consistently above 70 degrees Fahrenheit.

When to Plant Caladium Bulbs in Houston

Caladiums are tropical plants that thrive in warm, humid conditions. In Houston, the best time to plant caladium bulbs is in late spring or early summer, after the threat of frost has passed. Planting them in the right conditions will ensure that they grow healthy and produce beautiful foliage.

1. Soil and Sunlight

Caladiums prefer well-draining soil that is rich in organic matter, such as peat moss or compost. They also require partial to full shade, as direct sunlight can scorch their leaves. Planting them in a garden bed that receives morning sun and afternoon shade is ideal.

2. Temperature and Moisture

Caladiums prefer warm temperatures, with soil temperatures at least 65°F (18°C) for best results. They also require consistent moisture, but not waterlogged soil. In Houston, where rainfall is abundant, it is important to ensure that the soil drains well to prevent waterlogging.

3. USDA Zone and Average Last Frost

Houston is located in USDA Zone 9a, which means the average minimum temperature is between 20°F (-6.7°C) to 25°F (-3.9°C). The average last frost in Houston is around February 14th, which means it is safe to plant caladium bulbs in late spring or early summer.

Preparing Caladium Bulbs for Planting

Before planting caladium bulbs, it is important to properly prepare them to ensure optimal growth. Here are some tips for preparing caladium bulbs for planting, whether in containers or in the ground.

1. Bulbs

When selecting caladium bulbs, it is important to choose bulbs that are firm and free of blemishes or mold. Soft or damaged bulbs may not grow properly or may be more susceptible to disease.

2. Containers and Pots

If planting caladiums in containers or pots, it is important to choose a container that is large enough to accommodate the bulbs and has adequate drainage holes. Caladiums prefer well-draining soil, so it is important to choose a potting mix that is rich in organic matter and perlite or vermiculite to improve drainage.

3. Drainage

Good drainage is essential for caladiums, as they do not like to be in standing water. To ensure proper drainage, it is important to choose a container or planting location that has adequate drainage holes and to add a layer of gravel or other coarse material to the bottom of the container or planting hole.

4. Fertilizer

Caladiums benefit from regular fertilization, particularly when grown in containers. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium can be applied every two weeks during the growing season.

Alternatively, bone meal or superphosphate can be added to the soil at planting time to provide slow-release nutrients.

5. Indoors

Caladiums can be grown indoors in bright, indirect light. When grown indoors, it is important to choose a container with adequate drainage and to water the plant when the soil feels dry to the touch.

6. Elephant Ear

Caladiums are often referred to as elephant ear plants due to their large, heart-shaped leaves. When planting caladium bulbs, it is important to position them with the pointed end facing up and the round end facing down.

By following these tips for preparing caladium bulbs for planting, gardeners can ensure healthy growth and beautiful foliage throughout the growing season.

Planting and Caring for Caladiums

Caladiums are beautiful foliage plants that are perfect for adding color to shady spots in Houston gardens. When planting caladium bulbs, it is important to choose a location that receives filtered sunlight and shade. Direct sun exposure can cause the colorful foliage to fade.

In Houston, caladium bulbs should be planted in the spring when the air temperature is at least 60°F and soil temperatures are at least a minimum of 65°F. The ideal time to plant caladium bulbs in Houston is from late March to early May.

To plant caladium bulbs, dig a hole that is about 2-3 inches deep and place the bulb with the pointed end facing up. Cover the bulb with soil and water the area thoroughly. Caladium bulbs should be planted about 8-12 inches apart to allow for proper growth and spacing.

Watering is an important part of caring for caladiums. Caladiums prefer moist soil, but they do not like to be waterlogged. Water the plants thoroughly once a week and make sure the soil is well-drained. Mulching around the plants can help retain moisture in the soil and prevent weed growth.

In Houston, caladium plants are susceptible to damage from snails and slugs. To prevent damage, apply a slug and snail bait around the plants. Additionally, caladium plants can be affected by cold weather and frost. Covering the plants with a sheet or blanket on cold nights can help protect them from frost damage.

Caladium plants grow to be about 12-24 inches tall, depending on the variety. To encourage growth and bud development, fertilize the plants every 4-6 weeks with a balanced fertilizer. When the leaves of the caladium plants begin to die back in the fall, stop watering them and allow the plants to go dormant.

When it comes to spacing, caladium plants should be planted about 8-12 inches apart. This allows for proper growth and spacing between plants. To help the plants establish themselves, add a layer of dry peat moss around the plants. This will help retain moisture in the soil and provide nutrients for the plants.

Caladiums and Other Plants

Caladiums are tropical plants that are known for their large, heart-shaped leaves that come in a variety of colors and patterns. They are a popular choice for gardeners in Houston due to their ability to thrive in the hot and humid climate.
