December 30 and January 1: Got Squirrels?

Feeding the birds in the winter means feeding the squirrels too. Many folks enjoy watching these clever acrobats but they do eat a lot of seed meant for the birds, and that can get costly. Adding a squirrel proof feeder or deterrents to your existing feeders can limit their consumption. In this segment we will explore those options and find out what works and what doesn’t.

December 8 and 11: Manchester's Blue Trees Project (Part 1)

Manchester’s Blue Trees Projects has people talking, and that is just the point. The Currier Museum of Art recently commissioned international artist and conceptual sculptor, Konstantin Dimopoulos, to create a temporary art installation - a landscape of nearly 100 vibrant blue neighborhood trees that surround the Museum and trickle south to Pulaski and Victory Parks. At Family Fun Day, Kon and his business partner and wife Adele involved hundreds of community members to join in and help color trees. 

UNH Cooperative Extension, the Society for the Protection of NH Forests, and other organizations that care for NH forests and trees are also part of the conversation. Now that the environmentally-safe-temporary-blue coloring has gotten people's attention, let’s talk about the importance of trees and forests to our state, cities, towns, and to each of our lives. 

In part 1 of this Grow it Green segment, we look at the art installation, learn about the artist’s global message and begin our local conversation about NH’s forests.

December 1 and 4: Storing Seeds

Whether you save your own seeds or simply have some leftover at the end of the season, it’s important to know how to properly store them. Many types of seeds have the potential to remain viable for years if they are kept under the right conditions. It’s possible that you may not need to purchase new seed every season if you properly store your seeds in a cool, dry place.

Nov 17 and 20: Wait to Prune your Trees and Shrubs

Fall is the time we think about performing many garden chores. It’s often tempting to prune trees and shrubs as they lose their leaves because it is easier to see their branch structure, but don’t do it! The goal of pruning is to improve the health of the tree, while causing as little damage as possible. Fall pruning has the potential to cause significant dieback, because wounds are more susceptible to damage from severe winter temperatures. There are plenty of other things you can do to keep busy in the garden in the late fall. Save the pruning for the late dormant season in late winter and early spring.

November 10 and 13: Firewood Pests

Many people enjoy having a wood-burning stove or fireplace in their homes for the warmth, comfort and homey feel it can bring -- especially in the cold of winter. But the firewood that is brought into the home for that fire isn't always quite as comforting, as there are a numerous household pests that can be carried in with the firewood.

October 20 and 23: Pumpkins

Pumpkins and squashes are some of the most popular fall decorations. For those that are interested in growing them, there can be some confusion over which is which. Both squashes and pumpkins can be ingredients in pumpkin pie, and some large squashes can be ornamentals. All pumpkins and squashes are closely related member of the same plant family, which includes, summer squash, cucumbers, and melons. If you decide to grow your own pumpkins or squash next season, have a clear idea of what you want to use them for. You’ll need to select specific varieties for decorations, pies, and giant competition pumpkins.

September 29 and October 2: Protecting the Garden from Deer

If you garden in New Hampshire, you have undoubtedly come into conflict with deer at some point. White-tailed deer are thriving in New Hampshire, in part because they are incredibly adaptable when it comes to habitat. Deer can live just as successfully in rural woodlands as they can on farmlands or in suburban gardens. Urban deer are especially problematic as they have very few predators and hunting is often not an option where homes are closely spaced. While it’s clear the deer are here to stay, that doesn’t mean there isn’t anything you can do to stop them. Fortunately, there are three key strategies you can implement to limit deer damage in your garden this season.

September 1 and 4: Invite Pollinators Inn (Building a Bee Hotel)

Most people are familiar with honey bees as pollinators, but there are thousands of native and non-native solitary bee species that also aid in pollination. Solitary bees, unlike honey bees, do not live in a social structure, but in natural and man-made cavities. These can easily be provided with nesting habitats.

August 25 and 28: Planting for Hummingbirds          

Ruby-throated hummingbirds are one of the most charismatic bird species in New Hampshire. Many people attract hummingbirds to their backyards with hummingbird feeders. While these can be effective, hummingbirds are equally, if not more attracted to a variety of common garden flowers. Native plants are always a good choice, but you don’t need to limit yourself. Hummingbirds usually prefer tubular flowers that are high in nectar. Plants such as cardinal flower, trumpet honeysuckle, bee-balm, agastache, and salvia will all attract hummingbirds. In this episode of Grow it Green you’ll learn how to make your own garden a hummingbird haven.

August 18 and 21: Harvesting & Storing Fresh Produce

The flavor, freshness, and nutritional content of fruits and vegetables is determined entirely upon the maturity and time of day when they are harvested. Vegetables that are too mature may be tough and stringy, while those that picked too soon may be flavorless and have fewer nutrients. The time of day fruits and vegetables are picked and the way they are stored can also have a big impact on quality.

August 4 and 7: Stink bugs: Do they all stink?

Though they’ve gotten a deservedly bad reputation, not all stink bugs are crop pests. Some are beneficial and prey on other crop pests, especially in vegetable production. Knowing the difference between good stink bugs and bad stink bugs is a good thing. This segment of Grow it Green we will focus our attention on some of the key characteristics in telling the good from the bad.

July 28 and 31: Low Cost and Local Mulches That Control Weeds and Improve Soil

What some people may consider “waste products” others call “black gold”, when speaking of many natural materials leftover from tree crews, mowing of lawns, and even shearing of sheep. These leftovers can be locally accessed for low or no cost and be used as mulches that reduce weeding and build nutrient-rich, moisture-holding soil. In this segment we learn the differences and benefits of some of these locally-sourced plant-based mulches including ramial chipped wood, mixed wood chips, shredded wood mulch, pine needles, grass clippings, and even a non-plant-based but lanolin-rich mulch…wool!

May 12 and 15: Pesticides and Reading a Label

A pesticide is any substance used to kill, repel, or control certain forms of plant or animal life that are considered to be pests. Before reaching for a pesticide it is important to not only know what it is you are trying to control or manage, but what the label is telling you. Reading a pesticide label is one of the most important things a person can do before applying anything to the environment. This segment of GIG will help a person determine whether or not a pesticide is really needed.

May 5 and May 8: Choosing The Right Tree

Spring is a great time to plant new trees. The soil is moist, temperatures are mild, and trees have an entire growing season to become established. Purchasing a new tree is often a big investment, so you want to make sure you’ve made a good choice. Before you buy a new tree, you need to pay attention to site conditions. Note the slope, hardiness zone, soil type, exposure, soil compaction, amount of light, drainage, space or size, and soil pH/nutrient availability. After evaluating the spot where it will be planted, pick a tree that will adjust well to that location. Without exception, the needs of the tree should match those provided by the site. When selecting a tree keep the following things in mind: the tree’s potential size, cultural requirements, rate of growth, maintenance needs, and susceptibility to insects and diseases. In this episode you’ll learn all about how to choose the right tree for the right location, as well as take a look at some hardy trees that are perfect for spots with tough growing conditions.

April 21 and 24: Spring Cleanup and Characteristics of a Low Maintenance Landscape

How does a low maintenance landscape compare to others in early spring? This landscape at Rolling Green Nursery with a variety of plants, layers, and textures completely covers the soil and is still attractive even in early spring before flowers and new growth. Low maintenance is not no maintenance. Creating landscapes that build soil and keep it covered, and establishing layers of plants chosen for the right site conditions, wildlife habitat, and year round interest, allows you to spend more time enjoying and observing rather than mowing, weeding, watering, and mulching.

April 14 and 17: Caring For Houseplants

Spring is the perfect time to give your houseplants some renewed attention. As the outside temperatures warm and the days lengthen, it’s time to consider caring for your houseplants. Most houseplants will start actively growing in the spring, which makes this a good time of year to start fertilizing and repotting. Your houseplants may need to be repotted if the roots are beginning to show through the drainage holes or on the soil surface, if new leaves appear smaller than normal, or if the plant wilts soon after watering. Houseplants also require occasional fertilization to keep them happy. In this segment you will learn how to reinvigorate your houseplants and keep them thriving.
