Gardening Advice

To keep Kalanchoe flowers blooming beautifully, proper care is essential. Here are some practical tips:

Light

Kalanchoe thrives in bright sunlight but avoid harsh, direct sunlight during summer. Indoors, place the plant near a well-lit window.

Watering

As a succulent, Kalanchoe prefers dry conditions. Water thoroughly only when the soil is completely dry. Reduce watering frequency in winter to prevent root rot.

Soil

Use well-draining soil. Succulent potting mix is ideal, or you can mix regular potting soil with sand or perlite to enhance drainage.

Fertilizer

During the blooming period, feed the plant once or twice a month with a phosphorus-rich liquid fertilizer to promote flowering. Avoid over-fertilizing.

Pruning

Remove spent flower stalks promptly after blooming. Trim overgrown stems to maintain a balanced shape and encourage new flower buds.

Repotting

Repot Kalanchoe every 1–2 years in spring or autumn to accommodate root growth. Use a slightly larger pot each time.
