by

Repotting your Mammillaria cactus is an essential part of its care routine, helping it grow healthily and preventing root rot. However, this process can sometimes expose your plant to pests that may harm it. Being vigilant after repotting can ensure your Mammillaria remains healthy and pest-free.

Pests Commonly Found After Repotting

  • Mealybugs: Small, white, cotton-like insects that cluster around the base and crevices of the cactus.
  • Scale Insects: Hard or soft shell insects that attach themselves firmly to the plant’s surface.
  • Spider Mites: Tiny, red or yellow pests that create fine webbing on the plant.
  • Fungus Gnats: Small flying insects that lay eggs in moist soil, often a sign of overwatering.

Signs of Pest Infestation

  • Discoloration or yellowing of the cactus skin
  • Sticky residue or honeydew on the surface
  • Visible insects or webbing
  • Soft or rotting areas around the roots
  • Slow growth or decline in overall plant health

Preventive Measures

  • Use sterile soil and clean pots before repotting.
  • Inspect the plant carefully before and after repotting.
  • Avoid overwatering, which attracts fungus gnats.
  • Ensure proper drainage to prevent excess moisture.
  • Maintain good air circulation around your plant.

How to Treat Pest Infestations

If you notice pests on your Mammillaria, act quickly to prevent further damage. Here are some effective treatment options:

  • Manual removal: Use a soft brush or cloth to gently wipe off pests.
  • Insecticidal soap: Spray the plant with a solution designed for succulents and cacti.
  • Neem oil: Apply neem oil to deter pests and prevent infestations.
  • Isolate the plant: Keep the affected plant away from others to prevent spreading.
  • Repot if necessary: Remove contaminated soil and replace it with fresh, sterile soil.

Conclusion

Protecting your Mammillaria after repotting is crucial for its health and longevity. Regular inspection and prompt action against pests can keep your cactus thriving. Remember, early detection and treatment are key to managing any pest problems effectively.
