| During a hard rain last week I noticed that as the water was running down the trunk of a 50-year-old pine a foam-like substance gathered at the bottom of the trunk. Could this be a problem? Thanks for your help. Suzanne |
| What you describe sounds like stemflow (a forestry term). Sometimes, during or after a heavy rain a white bubbly foam, like soap suds will appear at the base of some of the pines. It disappears after the rain ends, and doesn't seem to appear during drier weather. As long as you don't see physical damage from insects (look for holes in the bark), what you've witnessed is quite common. |
