Master Gardener volunteers are trained to answer a variety of questions about gardening topics specific to our local climate, such as:
- when to plant vegetables outdoors
- which native plants will thrive in your space
- how to identify pollinator-friendly plants
- pruning tips
- common plant problems, diseases, and solutions
- lawn/turf care, and more.
For best results, please email a detailed description of your plant concern or question and include two or three high quality photos if possible.
Master Gardener volunteers will be on site at the Lehigh office from April–Sept, M-F, 9am–12pm; and at the Northampton office from April-Sept, M-Th, 9am–12pm. Please call the office before bringing in samples.
Soil Tests
Soil fertility testing is often recommended by Penn State Extension Master Gardeners as a first step toward healthy plant growth. Read "Don't Guess…Soil Test," to find out what our soil fertility tests measure (and what they don't), instructions on how to take a good soil sample, pricing, timing, helpful links, and more.
There are two ways to get a Penn State Extension soil fertility test:
- Mailing kits can be purchased at our office during regular business hours. For best service, please call the office before stopping by.
- Soil fertility test forms, pricing, and instructions can be viewed and printed from the comfort of your home or office. If you choose this method, you will supply your own mailing bags and mail your payment directly to the lab along with your soil sample.
After submitting your soil sample, the lab will forward a fertility report within about two weeks that includes a chemical analysis of your soil along with recommendations for soil improvement specific to your crops. For faster results, please be sure to include your email.
To pick up a soil or water test kit, please visit our Northampton office or our Lehigh office. For best service, please call the office before stopping by.
