It's harvest season fellow Granite Staters!

That also means that it's time to preserve the harvest.

We always recommend using tested recipes from legitimate sources for food preservation.

Here are some of our favorite places to find canning and other food preservation recipes and articles-

Did you know that New Hampshire has over 50 native wild orchids?

You probably have seen the pink lady's slipper (NH's official state wildflower and quite the flashy flower!) but there are so many more! Some are very rare and others are even endangered.

They are absolutely fascinating plants that harness a symbiotic relationship with mycorrhizal fungi to germinate seeds and grow.

As tempting as it can be to pick them, we always recommend that people leave native wildflowers where they are and let them continue to grow in their wild habitat.

This white bog orchid (Platanthera dilatata) was found this past weekend in the White Mountain National Forest.

Have you seen other native wild orchids in New Hampshire?

Ever Heard of dog vomit slime mold?

A UNH Extension Yard and Garden Infoline client recently reached out to us asking what the heck was growing in their garden bed!

Our response:

Thank you for contacting the Yard and Garden Infoline. We are happy to help! The following research was completed by Master Gardener volunteer, Heidi:

The photo and correct ID of this slime mold was quite helpful, since that is exactly what is happening! When beds have access to dead or decaying material, these slime molds appear. It often can occur in playground areas with decaying wood chip mulch.

https://extension.unh.edu/blog/2025/06/perils-mulch-summer

The slime mold is harmless and as this above link indicates, the easiest way to deal with them is to either leave them alone and appreciate the beauty of nature and the process of decomposition, or just physically move them elsewhere, if their appearance is unappealing to you!

Thanks for asking, and I hope your green beans are growing wonderfully well, with the added nutrients that the raised bed is providing for from! Please do not hesitate to ask any other questions. We are happy to help!
