Poor Drainage in Your Pot Can Also Make Root Rot:

One of the important factors that make your plant rot is the pot you use for growing the plant. If you place the plant in a small pot and if the pot does not have enough holes to drain out the water, it will be a reason for the increase in moisture content in the soil.

So choose a perfect pot that has drainage holes and a sufficient place to make your plant breathe. If the holes are very narrow, it will also make the soil absorb excess water and settle in the bottom of the pot.

If you place the pot in the ground, then the drainage holes will be locked. If it is locked, then the moisture content will stay.

Important Tips

  • You can prefer hanging your plant in tall places, which eventually drains excessive water if the pot has proper drainage holes.
  • If the position does not suit your setup, place your pot on tables with a hole in them, or just place the pot in bricks b arranging the bricks in order.
  • You can use ten to fifteen bricks to arrange them in all the direction and make the bricks look like a triangle so that anyone can place a pot in it to have drainage area.
  • If the soil is dense, then it will also be a reason for Root rot. Always use soil moderately; never make your root completely hide in the soil; just leave some extra space and pour some water to make them attain proper moisture.
  • If you prefer to overload the root with excessive soil, it will create excessive moisture and be another reason for root rot.

Pathogenic Infections Can Also Make Your Plant Root Rot:

Pathogens such as pythium, fusarium and some other fungal infections can grow well in wet soil, so keeping your soil in moisture all the time will be a chance for these fungal infections to spread well into the soil and affect the roots.

How to Prevent Pathogenic infections?

Pathogenic infections spread well in wet environments; we should first allow the soil to dry to its core. As Peace lily has some withstanding ability, it is easy for them to overcome dryness. Allow them to dry completely and water after inspecting the soil.

Never use garden sands for pots because they will be rich in moisture and allow pathogenic infections to reach your plant easily. So use organic pot grade sand for better results.

Disinfect your tools regularly: You may cut several plants or use them to trim in various situations. If you use the same tool after cutting the infected plant, then the healthy plant may also get the same disease which is more dangerous.

Never reuse infected soil, which is already a victim of pathogenic infection.
