How to Grow the Cat's Whiskers Plant
The cat's whiskers plant is native to tropical regions, which is why you need to pay attention to its light, temperature, and watering needs. This plant will grow well, if you provide it with the conditions found in tropical or subtropical environment. Here are some tips and instructions on caring for the cat's whiskers plant.
Light and Temperature
It's the stamen, the male reproduction organ of the flower, that imparts this plant its characteristic whisker-like appearance. If the planting site or the location at which the plant is placed doesn't receive sunlight, the number of blooms are most likely to get reduced. So, make sure that you put the pot at a place or plant it in the part of garden that receives full sun. Though the plant can also tolerate partial or dappled shade, make sure that it receives some direct sunlight during the day. It is hardy to USDA zones 9-11, which means that it can withstand the minimum temperature of 20°F.
Watering
For this plant to thrive, you need to ensure that you water it thoroughly, so that the soil remains moist. Deep watering is required to ensure that water reaches down to the roots. Increase the frequency of watering during dry spells. Make sure that you do not allow the soil to become completely dry before you water it again. However, going on a watering spree is not recommended. The soil should be moist, and not waterlogged.
Soil and Fertilizer
The cat's whiskers plant requires well-drained soil. It can be neutral or mildly acidic. If used as a bedding plant, spread a 3-inch layer of organic compost. Thereafter, mix it down to a depth of 6 to 8 inches into the soil. You can also apply one pound of slow-release 12-6-6 NPK (Nitrogen-Phosphorous-Potassium) fertilizer per 100 sq. ft. of the plant bed. Application of fertilizer is essential from spring through summer. Apply the fertilizer as per the directions provided on the label. Reduce the frequency during winter.
Pruning
Being a fast-growing plant with a shrubby habit, you might need to prune or trim the plant from late spring through fall. Remove the spent flowers or old flower stems, and also look for damaged foliage or stems. Cut them back to near the ground to encourage new growth. Slugs or snails could cause damage to the foliage. Take necessary precautions if there's an infestation.
The cat's whiskers plant not only has a distinctive appearance, it is also known for attractive bees, butterflies, and hummingbirds. On a concluding note, you will never regret the decision of including this plant in your garden.
