Sunburn causing yellow leaves in peace lily

Though the peace lily is a tropic plant it does not require too much sunlight. These plants do well in low light conditions. The only exception is that they find it harder to bloom when in a darker room. Most gardening experts advise that the plant is kept in a spot that receives bright indirect sunlight. 

This is why when the plant is placed in a sunny spot you notice discoloration. It starts with a yellow tint that turns brown over time. If not treated on time the plant can wilt. 

How to fix it:

When it comes to fixing a sunburn situation here is what you can do 

  • Change the location of the plant immediately. This will in no way reverse the effect on the already damaged leaves but will surely protect the others. 
  • Mist the plant often. This works as a cooling agent for the plant. As peace lilies are tropical beauties they do well in a moist environment.
  • Place the plant in a warm spot.
  • If you cannot move the plant you can install curtains or sheets to protect the plant from direct sun rays.

Note: if you live in a non-sunny location and use artificial lights. There is a chance this can cause burns and yellow leaves as well. To protect the plant from this

  • Avoid placing the plant directly under artificial light if that’s something you are using. Artificial gardening lights are installed to mimic the sun. Hence the damage they cause is also of the same intensity.

Improper watering causing yellow leaves in peace lily

Improper watering is the major cause of discoloration in plants. This can go two ways either you over water the plant. In a way that the plant is left in soggy soil, succumb to a root condition and discolor.

Or you underwater the plant and it cannot soak in nutrients from the soil. Either way, improper watering will cause yellowing of the leaves of your peace lily.

Let’s look at both the problem separately and list ways in which you can fix the problem.

Overwatering the peace lily

The peace lily is a moisture-loving plant but it cannot stand soggy soil. These plants are prone to root rot and other conditions if left in soil that is soggy. 

How to fix it 

  • Have a watering schedule

When you have a watering schedule and stick to it, there are fewer chances of overwatering the plant

  • Water only when the top one inch is dry

This is another way you can be sure that the plant needs to be watered. 

  • Drainage holes at the base of the pot

When you drill drainage holes at the base of the pot the excess water can drain easily. This reduces the chances of the soil getting soggy.

  • Adding a draining agent to your potting mix

Draining agents like sand, pieces of clay pots, pebbles, etc. can be used to make the potting mix lighter and easy draining.

  • Not letting the plant sit in a wet tray

Letting the plant sit in a wet tray is considered as dangerous as overwatering. By doing so the excess water drained from the pot is soaked up by the plant. This causes the roots to rot. The best way is to empty the tray as soon as you finish watering the plant. 

Underwatering a peace lily

Like overwatering, underwatering is also a major concern when it comes to yellow leaves on a peace lily. When the plant is under-watered it cannot absorb the nutrients from the soil. This causes the plant to turn yellow and eventually wilt. 

How to fix it

  • Stick to a watering schedule
  • If you notice cracks in the soil it means you have gone too long without watering the plant. 
  • Water the plant in accordance with the climate. On hotter days/months you will need to water your peace lily more often.
