About the Helpline
The Garden Helpline is staffed all year with Master Gardener volunteers to assist the citizens of Union County. Helpliners are trained by Rutgers to handle a wide range of questions. In the winter the HL assists with control of household pests and in the growing season we help answer garden and landscape questions. Helpliners can also be found at county festivals selling soil test and manning a Helpline table.
