Horrible place. Not using federal dollars for anything more than teaching kids how to shoot guns and to use Monsanto products!

Hello, I live in a condo development in Goffstown NH. Our water bill has gone up significantly so they want to control our watering. We have rocky poor soil. What is the correct amount to water for poor lawns. They want 1 hour per week.

Diane Anderson | Aug 22, 2021
UNH Cooperative Extension | Aug 22, 2021

The amount is more important than the duration. You want the soil to be wetted 4-6 inches deep and then let it dry out before watering again. That is likely around an inch of water, so you can set a small can in the lawn under the sprinkler and time how long it takes to reach an inch of water. Usually, watering 2-3 times a week is sufficient when it doesn't rain. Our friends in Massachusetts Extension have a particularly good fact sheet on efficient watering https://ag.umass.edu/landscape/fact-sheets/efficient-outdoor-watering. good luck

We have blue spruce shrubs on our town common. One has started in the top with dying needles and dried branches. As they are in the center of town we need to try and fix the problem before it spreads to the other bushes. What do you suggest?

I have two established maple trees (15-20 years). This year they have very little foliage and most buds are dried up. What leaves there are, are mostly confined to the lower branches. Every year the trees have appeared healthy. Ideas?

Do carpenter ants have any good purpose? Perhaps speeding up the decay of dead trees? I can't find any positive comments about these critters online. Thank you!

Yes, carpenter ants play a role in breaking down woody material in nature. However, most of the information you'll find on them deal with the problems they can cause to human-built structures. This post has more about them: https://extension.unh.edu/resource/carpenter-ants-fact-sheet

Where do I take a soil sample to find its PH ?

A Google User | Aug 23, 2018
UNH Cooperative Extension | Aug 23, 2019

From: https://extension.unh.edu/blog/best-practices-submitting-your-soil-sample - The soil sample should be representative of the area for which you want recommendations. - Avoid areas that have an obvious difference in soil type, drainage, or plant growth. - Take samples from 6-8 spots in each garden or lawn area you want tested. Mix these 6-8 spots together to create a representative sample of the area. - Each sample should be taken from a depth of 6" for gardens, 6"- 8" for trees and shrubs, and 3-4" for lawns. - The sample can be taken with a spade, shovel, trowel, soil probe or auger. - Air dry, remove stones and other debris.
