Crocosmia Bulbs – 25 Mixed Color Montbretia Tubers for Planting – Hardy Flowers

Planting and Growing Mixed Color Crocosmia Bulbs

Growing Crocosmia bulbs, also known as montbretia, is a delightful way to add vibrant color to your garden. These hardy flowers are relatively easy to grow if you provide the right conditions. By following a few simple steps, you can enjoy their stunning blooms from mid-summer to fall. The mixed colors, including shades of red, orange, yellow, and pink, create a visually appealing display that attracts hummingbirds and butterflies.

The first step is choosing the right location. Crocosmias thrive in full sun, requiring at least 6 hours of sunlight each day. While they can tolerate some light shade, they flower best when exposed to ample sunlight. Ensure that the soil is well-drained. If your soil is heavy or clay-like, amend it with compost or organic matter to improve drainage. Good soil drainage is crucial to prevent bulb rot and ensure healthy growth. Planting Montbretia tubers in the spring, after the last frost, is ideal. Aim for April or early May, depending on your climate zone. Plant the bulbs about 3-4 inches deep and space them 6-8 inches apart to allow for their spreading growth. When planting, the pointed side of the bulb should face upwards. If you’re unsure, planting the bulb on its side works just as well.

Watering and fertilizing are vital for healthy Crocosmia growth. Water the bulbs immediately after planting and continue to water regularly throughout the growing season, especially during dry periods. Avoid over-watering to prevent bulb rot. Fertilize in the spring as new growth appears using a balanced, slow-release fertilizer. A high-potassium fertilizer during the growing season will encourage more abundant blooming. Caring for your plants includes mulching, staking, and deadheading. Apply a layer of mulch around the plants to retain moisture, keep the roots cool, and suppress weeds. Some varieties can grow tall, so consider staking or supporting the plants if they become top-heavy. Regularly remove spent flowers to encourage more blooms and keep the plant looking tidy.

Overwintering Crocosmia depends on your climate. In frost-prone areas, Crocosmias are not fully hardy, and you may need to lift the bulbs in the fall before the first frost. Dry them out and store them in a cool, dry place until spring. In mild climates (USDA Zones 6-9), the bulbs can overwinter in the ground, but mulching them heavily can protect them from freezing temperatures. Crocosmias are generally pest-resistant but can sometimes suffer from aphids, slugs, or snails. Keep an eye out for signs of pests and use appropriate control methods if necessary. Proper spacing allows good air circulation, reducing the risk of fungal diseases. By following these guidelines, you can enjoy a vibrant garden filled with colorful hardy flowers.
