However, direct sunlight would be beneficial to the Persian Shield houseplant as it could help promote a richer and more flourishing look. 

Prolonged exposure to direct sunlight could prove damaging to the exotic houseplant. What you should aim for when it comes to the Persian Shield sun requirements should be a maximum of 6 to 7 hours of direct sunlight a day after which, you provide partial or shade sunlight for the remaining part of the day 

Too little sunlight could lead to the exotic foliage drooping, but it can be awakened by providing quick and sufficient access to direct sunlight. 

Persian Shield Water Requirement

Another reason why a Persian shield plant might be drooping would be a lack of good watering practice. 

The Persian plant might not need excess watering but it is advised that you keep its soil moist at all times. Be careful not to overwater it though. 

 What you should aim for when it comes to watering should be providing it with at least 1 inch of water every week. 

On a hot day with humid climates, you might want to increase the watering frequency. Water it every day, so as to avoid the plant wilting would be most ideal 

If it does wilt or droop, do not be alarmed,  a simple drink of water should be more than enough to get it back to its flourishing vibrant self in no time. 

Persian Shield Soil Requirement

The Strobilanthes Persian shield plant has delicate roots, so you would want to avoid soggy soil as much as possible. 

Persian Shield Soil Requirement

Pick a soil mix that is well-draining and rich in organic matter. By combining perlite with houseplant soil and peat moss, you provide a perfect soil type for the Persian Shield plant. 

The appropriate pH soil level should range from neutral to acidic. Keep it between the range of 5.5 to 7.5. 

In addition to the soil type being well-draining, it also helps to have a decent level of water-retaining capacity, so as to remain moist at all times. 

Persian Shield Humidity and Temperature Requirement 

The average humidity level of the Myanmar tropical regions is high so the Strobilanthes plant would do well in a warm and humid environment. 

A dry climate would be terrible for its exotic leaves as they would wither and dry out. What you should aim for is a temperature level of 60 degrees Fahrenheit and above, with as much humidity as possible.

Making use of a humidifier would be good practice if you find that the natural climate indoors is not humid enough. 

You could also try misting your Persian Shield plant every day, just be sure to clean water that is free from chlorine as such chemicals could be bad for the luxurious foliage.

Persian Shield Fertilizer Requirement   

How often you feed your Srobilanthes Dyeriana plant depends on the type of soil that it was planted on. If soil rich in organic matter was used, then a less frequent feeding schedule would be required. 

If the soil used contains little organic matter, then an average fertilizing schedule should be adopted. When fertilizing, ensure it is a liquid soluble fertilizer with about half its initial strength diluted. 

Fertilizing can be done every 2 weeks or 4 weeks, and ensure the fertilizer used contains more nitrogen as that is the key nutrient needed by the plant. 

Persian Shield Propagation 

When propagating the Persian shield, it can be done by stem cuttings. This is a delicate procedure so do be careful so as not to injure the plant with your propagating tools.
