Calceolaria crenatiflora
Calceolaria crenatiflora is a charming evergreen houseplant presenting leaves that grow in patterns and an array of small flowers that are typically orange in color. Native to Central and South American countries, this houseplant is an easy-going choice for houseplant novices and lovers alike. The blooms of Calceolaria crenatiflora can be enjoyed in the spring and summer months with proper care.
This houseplant should be watered when its soil feels dry one to two inches below the surface. An easy way to check for moisture is to use your finger. If it feels dry, it's time to water. When watering, use lukewarm water and carefully saturate the soil. The soil should not be soaked too much as it may cause root rot. When you're done, water should drain from the bottom of the pot. Avoid overwatering as it can be fatal for this houseplant.
Calceolaria crenatiflora should be grown in bright, filtered light. Too much direct sunlight may scorch its delicate blooms and leaves. If grown indoors, the houseplant should be placed near a sunny window where it will receive indirect sunlight throughout the day. Avoid dark spots as these will compromise the growth of your Calceolaria crenatiflora.
Calceolaria crenatiflora prefers temperatures ranging from 64–72ºF (18–22ºC). Temperatures should not dip below 50ºF (10ºC) as this may cause the leaves and flowers to become wilted. Similarly, temperatures that are too warm may also cause the plant to become stressed. Humid summers are the ideal environment for this houseplant.
Calceolaria crenatiflora thrives in moist and humid environments. For those with dry air, it is recommended to mist the plant's leaves or place the pot on a pebble tray with water in it. Make sure the pot is not sitting directly in water, as it can lead to root rot.
Calceolaria crenatiflora prefers a well-draining, loose potting mix. To create an ideal environment for your Calceolaria, mix cactus soil, perlite, and pozzolan in equal parts. The soil should be slightly acidic with a pH of 6-7. Do not forget to add a potting tray beneath your pot to catch excess water and ensure proper drainage.
Fertilizing your Calceolaria crenatiflora is important to ensure it thrives and produces its flowers. During its blooming season, use a liquid fertilizer with high phosphate content at least once a month to help the flowers become larger and brighter. A balanced fertilizer containing nitrogen, potassium, phosphorus, and other micro-nutrients is best for the health of this houseplant.
The most common pests bothersome to Calceolaria crenatiflora are mealybugs, spider mites, scale, and whiteflies. These pests can quickly cause damage to the delicate plant. If spotted, use neem oil or insecticidal soap to help control the pests. A natural solution is to use a cotton swab soaked in rubbing alcohol and gently rub on the affected areas. Make sure to dispose of pests off of the plant. Another effective technique is to use a high-pressure water stream to dislodge the pests from the leaves.
Repot your Calceolaria crenatiflora every two to three years as its growth is slow. Repot during its blooming season in the late spring or in early summer. Make sure not to overwhelm your houseplant with a pot too large for its growth as the excess soil may lead to overwatering.
Prune your Calceolaria crenatiflora when necessary to remove dead or diseased foliage. Take care when pruning as any significant pruning may affect its flowering success in the future. Prune under or just above the node while avoiding shortcuts and take care to sterilize the pruning tools between use.
Mulching your Calceolaria crenatiflora is not necessary, but it can provide an extra layer of protection for the soil and improve drainage. Non-chemical mulches such as peat moss, leaf mold, or shredded bark are best for this plant.
Propagating your Calceolaria crenatiflora is relatively easy. To propagate, start by taking cuttings from fresh stem growth. The cuttings should be about 3-4 inches long with at least two leaves. Place the cuttings in fresh soil and make sure the soil is kept moist. If the environment is humid, there is no need to mist the cuttings. Gain roots will begin to emerge after two to three weeks.
Calceolaria crenatiflora may not require staking or support due to its small size, but if your houseplant needs some support, it is necessary to provide. Gently tie the stems to a stake using soft cloth or string, while also being careful not to tie too tightly.
Calceolaria crenatiflora does not have an extreme rest period and so long as temperatures remain consistent it will continue to grow. However, during the cold winter months, you may notice the plant growing slower as this is normal.
Calceolaria crenatiflora is non-toxic to both cats and dogs, so there’s no need to worry about your pet’s wellbeing.
