Improper Sunlight Exposure

The purple oyster plant does best in bright indirect sunlight. The filtered light triggers blooming and encourage the houseplant to undertake its physiological activities. 

The low-light condition makes these attractive foliages lose their vibrancy. The situation also makes this oyster plant leggy and stunted. 

Be sure to relocate the houseplant to a place receiving bright indirect sunlight. Besides that, avoid direct sunlight exposure to prevent sunburn. 

Lack of Humidity

The boat lily plant prefers high humidity to thrive well. But this houseplant can still tolerate indoor humidity fluctuations. Be sure to maintain indoor humidity levels above 40%.

Low humidity level causes foliage discoloration and unhealthy growth. Dry air will make the purple oyster leaves turn brown at the tips and edges.

The best solution is to mist the leaves to increase humidity around the houseplant. Another excellent option is to install a humidifier to keep the indoor environment humid.

Nutritional Deficiency

The purple oyster is a fast-growing tradescantia species with moderate fertilizer needs. Feed the houseplant every month during spring and summer.

The nutrients from well-balanced houseplant fertilizer encourage fast and healthy growth. But too much fertilizer is toxic to the houseplant.

The excess salt accumulation around the root system makes these oyster plant leaves burn. Too low nutrients and minerals in the potting soil also cause purple leaves discoloration.

I recommend re-potting the purple oyster plant in case of over-fertilization and under-fertilization. It is the best method of avoiding leaves fading problem.

Temperature Stress

Oyster plants are native to areas with a tropical climate. The warm and humid environment allows this perennial plant to thrive well outdoors.

Indoor temperature fluctuation increases the risk of hot and cold drafts. These two conditions make the attractive leaves lose their vibrancy.

Be sure to replicate the natural habitat temperature range of 55-80oF at home. Besides that, keep the plant away from door and window drafts.

Overwatering Issues

The oyster plant is among a few forgiving tradescantia species. The houseplant can tolerate drought for a couple of days without becoming fussy.

But overwatering leave the potting soil soggy and increase the risk of root rot. The plant leaves losing their vibrancy is an initial sign of root rot.

The leaves’ discoloration occurs due to insufficient absorption of vital nutrients. The damaged roots will later result in wilting and even plant death.

Transplant Shock

Oyster plants are delicate when it comes to re-potting. Any slight root disruption will make the houseplant unhappy and unhealthy.

Re-potting the indoor plant due to root-bound issues could be the reason behind the leaves discoloration problem. But the foliages usually recover for a couple of weeks.

The golden rule is to exercise ultimate oyster plant care while re-potting and growing at home to avoid leaf discoloration.

Pests and Diseases

Oyster plants are vulnerable to spider mites, mealybugs, whiteflies, and scales. These insects usually munch the leaves and inject toxins that cause discoloration.

A combination of insect infestation and plant disease tends to ruin its health and foliage vibrancy. I recommend the use of insecticidal soap to get rid of pests from the houseplant.

Besides that, reduce the watering frequency to avoid the risks associated with overwatering. It is the best method to protect the houseplant from potential plant diseases.
