Clivia Sir John Thouron in terra-cotta pot

Latin Name Pronunciation: kly'-vee-ah min-ee-ay'-tah

Clivias have a well-earned reputation as rugged houseplants that demand very little attention.

LIGHT

• Clivias grow best where they receive bright daylight but little or no direct sun--in a north-facing window, for example, or in an east- or west-facing window that is partially shaded by a deciduous tree.
• You can summer your plant outdoors in a shady location. Just remember to bring it back in before the first frost. Clivias won't endure temperatures that dip much below freezing.

WATER

• Clivias prefer to be kept on the dry side. We strongly suggest that you avoid a weekly watering regimen and instead water only when the plant requires it.
• During the growing season, which begins after the "Winter Rest" and continues through October, water thoroughly (until water drains freely from the hole in the bottom of the pot) when the top inch of the potting mix becomes dry to the touch. Potting mix that remains constantly wet can cause rot, which is first manifested by the appearance of pale green or bright orange cankers on the leaves. 
• Please note that misting the leaves is neither necessary nor desirable and can encourage disease.

WINTER REST

• Clivias flower more reliably if you give them a period of rest in late fall. Begin this rest period once your plant arrives, and repeat it every year thereafter.
• For 12-14 weeks (about 3 months), keep the plant in light in a cool room (50-55°F is ideal) and withhold water.
• Keep a close eye on your plant during this resting period. If you notice that it is beginning to wilt, add a scant 1-2 cups of water, just enough to moisten the soil lightly.
• Begin normal watering (see "Water" above) at the end of the "Winter Rest". Bloom usually, but not always, follows in 6-12 weeks.

FERTILIZER

• After your plant has bloomed (generally in the period from April to August), fertilize it monthly with a water-soluble fertilizer (20-20-20) mixed at ½ the recommended strength.
• Use restraint: More fertilizer is not better. Stop fertilizing by mid-September.

GROOMING

• Cut flower stalks off at the base after the blooms have faded to prevent the plant from expending energy on the production of seeds. Also remove leaves that withered and turned brown.

REPOTTING

• Clivias tolerate considerable crowding of their roots and bloom best, in fact, when pot-bound.
• As a plant grows, some of the fleshy roots may push their way up above the potting mix. This is normal.
• Repotting is necessary only every 3-5 years. After bloom, lift the plant from its pot and place it in a new pot that is no more than 2" in diameter larger than the old one. Use a potting mix that drains well and that is composed of at least 50% organic matter, such as peat moss or fir bark. Most potting mixes sold at garden centers meet both requirements.
