August Gardening Tips for the Northeast: Watering Tips

Water plants a few hours before applying pesticides, especially during times of drought. In these conditions, plants have less water in tissues, and as pesticides enter cells, they may burn leaves.

Avoid watering during midday, when more water will evaporate than soak into soil.

It's not uncommon for plants to wilt on hot afternoons even though soil has adequate moisture. The wilting occurs because plants are losing water faster than their roots can absorb it. Leaves should revive by early evening, after the sun is no longer directly on leaves. If not, water deeply.

Some shrubs need weekly deep watering now. Rhododendrons are beginning to form flower buds for next year's show, and adequate water is vital. Fruiting plants, such as hollies and firethorn, need water to ensure berries mature and don't drop.

Test Garden Tip: Water newly planted trees, shrubs, and perennials -- any plants you added to your yard last fall or spring. These plants need weekly irrigation to ensure roots establish deeply.

Understanding Plant Hardiness Zones

You might've noticed when it comes to talking about plants that we sometimes include a zone number. That number is important because it helps you better determine what plants will not only grow, but thrive in your area. Check out this helpful map and corresponding legend from the USDA to figure out which zone you're located in.

The New York Botannical Garden: Creating a Bird Garden

Creating a bird garden is a wonderful way to attract birds to your yard. The best way to create a bird garden is to provide birds with what they need: shelter, food, water, and places to nest.

• Shelter:
  Birds need shelter to protect them from predators and the elements. In the winter, they need protection from snow, and during the year they seek refuge from heavy rain, wind, and predators.
• Food:
  Plants supply birds with a large part of their diet, from seeds and fruits to providing a home for the insects that many birds feed on.
• Water: Birds need water for drinking and bathing. Smaller birds tend to bathe in 1/2 inches of water, while larger birds prefer a 2-inch depth. You can build a small garden pond, buy a birdbath from a garden center, or place a large, shallow dish of water in your garden.
• Nesting Sites:Birds have different requirements for nesting sites.  Some birds like to build their nests in evergreens (such as pine or spruce), while others prefer deciduous trees (such as oak, birch, apple and ash), where they can make their homes either in the intersections of large branches or in cavities in tree trunks. Shrubs that are not too dense or thinly branched often make good homes for bird nests. However, plants such as rhododendrons and viburnums do not have the three-way forks in their branch structure that can support a nest.  While these shrubs offer important shelter and food for birds, they do not provide a suitable nesting site.

Designing a Bird Garden

• Design your garden with varying layers--tall trees, medium-size shrubs and perennials & ornamental grasses. This will accommodate many different types of birds.
• Plant your garden to provide shelter for birds. Planting evergreens on the northern side of your property will protect birds from cold northerly winds while allowing sunlight into the south side of the garden.
• Plant perennials and smaller shrubs in groups of threes, fives, or sevens to create a more natural look and to cover an area that birds can easily find and use. If you plant only one shrub that produces berries, for example, the berries may be decimated after birds' first visit.
• Variety is important -- select a range of plants that provide food at different times of the season and attract a variety of bird species.
• Create a dust bath in a sunny spot near the area where your birds feed. Sparrows in particular love to spend hours playing on dusty ground, and they are entertaining to watch.
• Although it is important to rake the leaves on your lawn to prevent turf die-off, do not remove leaf litter in your perennial beds or under your shrubs. These leaves will compost and provide important nutrients to the soil. They will also be a haven for many of the insects that birds feed on.
• Create a brush pile at the edge of your property, starting with your old Christmas tree and any fallen branches from trees and shrubs. Create a 6-foot-long pile with loosely stacked branches. Brush piles provide cover for birds and attract insects to their decaying branches.

Homemade Bird Feeder

It's not a plant, but a bird feeder can provide supplementary food for your bird garden. Here is a recipe for a simple one:

• Mix 1 cup of peanut butter with 1/4 cup of honey.
• Spread this mixture on a pine cone or bagel.
• Roll the pine cone or bagel in birdseed.
• Add a piece of yarn, and hang the feeder from a tree.

Explore the Benefits of Raised Beds

• Fewer weeds and easier weed control

• Better water retention

• Better drainage than New York’s hardpan

• Greater growing depth for plants

• Warmer soil earlier in the season, and warmer soil for a longer season

• Relatively neutral and sterile soil

• Less soil erosion

• Offers a non-compacted soil (not walked on!)

• Reduces the need to use poor native soil

• Offers a chance to go all the way around the bed, for less wear and tear on the body

• Can produce 1.4–2 times more vegetables per square foot

• Provides a gardening opportunity for the handicapped or similarly disabled

• Can be used for any plants, including ornamentals, vegetables and fruits

Optimal widths are 3–4 feet, with lengths up to 20 feet.
Wood, rock, or concrete blocks can be used.
Optimal height is 8–24 inches.
A foundation of rubble can be advantageous to aid in drainage.
Soil should be enriched with fair amounts of com- post. 

Space plants in geometric patterns to decrease the number of weeds that can grow.
Companion planting is encouraged!

The New York Botanical Garden: June Gardening Tips
