Burr knots growing into the soil?

I’ve read burr knots can be left alone, but do I still leave them alone if they are long and rooting into the soil?

Hi @tstokes2677

Burr knots are harmless adventitious roots that sometimes emerge near the base of trees. They can be left alone. They usually won't do much even if they reach the soil. You can always cut them off with a sharp knife if they detract from the beauty of your tree. If you want to read more about what burr knots are or why they happen checkout my reply to this post here.

Yes, burr knots can be left alone, however, if they are present in numbers then they can cause some problems such as -

  •  Making a way for pathogens and insects to enter the plant.
  • Stunting the growth of the plant by limiting phloem.

Therefore, you should take preventive measures and control the growth of burr knots to ensure the healthy growth of your plants. Hope this helped!W
