Clivia is a flowering subtropical plant that grows from an underground tuber. The flowers are borne in rounded clusters on thick, round, green stems atop deep green strap-like foliage that grows outward in a fountain form. The flower heads are reminiscent of a bunch of miniature amaryllis blooms. They're commonly coral orange and yellow in hue, but some rarer cultivars flower in a creamy white. Clivia is commonly grown as an indoor plant and benefits from regular but light doses of fertilizer throughout the growing season.
Choose a complete and balanced, water soluble fertilizer designed for flowering houseplants. Look for a guaranteed analysis of 10-10-10. Either a synthetic or organic product is acceptable.
Mix the fertilizer liquid or crystals with tepid water according to the product label dosing directions, but use just one-half of the recommended amount of fertilizer to a full volume of water. This will prevent the fertilizer from burning the tender roots or spurring fast, but weak, foliage growth.
Repeat this light fertilizer application once per month throughout the year to coincide with watering time. Water and fertilize clivia when the surface of the soil first feels dry to the touch to prevent over-watering and root rot.
