Free Rain Garden Workshop in Frederick County, Sept. 25th

Deadline for registration is September 22

The Potomac Conservancy, in partnership with the Interstate Commission on the Potomac River Basin, is hosting a free public rain garden workshop at Bar-T Mountainside (2914 Roderick Road. Urbana, MD 21704) on Saturday, September 25.

Learn how to manage stormwater and beautify your own backyard through rain gardens, pollinator gardens and other lawn-reducing practices. You will also learn how to select the right native plants for the project and how to ensure your project’s success. Participants will get hands on experience planting two gardens with native flowers, grasses and shrubs.

The workshop will be held from 10am – 4pm and includes a light lunch. Registration is capped at 30 participants ages 16 and up. Please RSVP to Aimee Weldon at weldon@potomac.org by September 22nd.

Why are rain gardens important?

Rain is natural; storm water run-off from man-made impervious surfaces isn.t. As residential subdivisions replace forests and agricultural land, storm water from increased impervious surfaces becomes a problem. Storm water run-off from developed areas increases flooding, carries pollutants from streets, parking areas and even lawns. Expensive storm water management structures are often required to address this problem.

By reducing storm water run-off, rain gardens can play a valuable role in changing these trends. While an individual rain garden may seem like a small thing, collectively they can produce substantial neighborhood and community-wide environmental benefits.

12 Benefits of Raised Bed Gardening

Last winter, our friends Jon and Kim Hindman of Wyoming showed us their snow covered back yard and said "And this is where we intend to build our raised bed vegetable gardens." They had the whole thing planned on paper and as the luscious smells of the home cooked meal they were preparing wafted through their cozy home, I could almost envision the joy they would get by adding homegrown herbs and veggies.

Jon and Kim being who they are, I wasn't really surprised that they got the gardens built, planted and harvested in what seems like an incredibly short time. (My husband and I are both such procrastinators, we do things at a snail's pace compared to Jon and Kim.)

Since they have a photo record of the whole process, I thought it only fitting to use their photos to help illustrate this post about:

 

The 12 Benefits of Raised Bed Gardening

1) Less soil compaction from people walking in the garden – Walking on garden soil exerts pressure of as much as ten pounds per square inch causing soil compaction.

2) Control of soil content - Raised beds are usually filled with high-quality soil mixes that have large amounts of organic matter

3) Easy maintenance - Raised beds are more easily maintained than ground beds since the increased height of the bed reduces bending distance

4) Better Drainage - Soil in raised beds is better drained than soil outside the bed. This increased drainage is especially helpful when growing plants in low-lying or poorly drained areas.

5) Better yields - Research has shown that raised bed gardening yields on average 1.25 pounds per square foot, more than double the conventional method

6) Water, fertilizer, compost, mulch, etc. can be applied more carefully

7) Easier to keep out burrowing pests - Burrowing animals can be stopped by lining the bottom of the bed with wire mesh.

8) Raised beds can extend your gardening season. They tend to warm up a little sooner in the spring and remain productive later in the fall

9) Gardening on bad sites or soils - Raised beds make gardening possible on sites where growing plants would otherwise be impossible. Rooftop gardens and raised beds on top of solid rock are examples. Terraced raised beds turn hillsides into productive growing areas while reducing soil erosion potential.

10) Water conservation - The narrow dimensions of beds are advantageous for water conservation. Canvas soaker hoses, perforated plastic sprinkle hoses and drip-type irrigation disperse water in a long, narrow pattern well-suited to beds. Directing water to the soil helps to reduce disease problems which can result from wetting the foliage with overhead sprinklers.

11) Less weeds - Dense planting techniques help reduce weed seed germination.

12) Better use of small spaces - Raised bed gardens can help maximize all available space and are typically smaller than traditional gardens, making them a more convenient option in areas with limited space.

Nice article about mulch

I found this nice article about mulch this morning. The writer reminds us of the benefits of using mulch.

Mulch reduces water loss from soil, which means less time spent watering your garden, and less water used. The use of mulch will minimize germination of weeds, so there’ll be fewer weeds to compete for water and nutrients, and fewer for you to pull. It improves soil aeration and drainage, and reduces soil erosion. Mulch insulates the soil, keeping it warmer during the winter months (which, shockingly, are just around the corner!). Mulch can also give your garden a well-groomed and professional appearance and keep your plants from becoming dirty. Click here to read the full article entitled Responsbile Gardening: Mulching

As a reminder, there are several places to get FREE or very low cost mulch in the Metro DC area. For details, visit our post on Free Mulch

Train your dog, train your man, train your lawn?

I’m reading a book right now called What Shamu Taught Me About Life Love and Marriage by Amy Sutherland. The premise is that you should be able to train your husband (or anyone else, for that matter, by using techniques created by famous animal trainers. I’m not very far into the book, so for now, my husband isn’t coming when called or heeling very well when we go for a walk.

However, with drought conditions in effect for much of the D.C. area, I thought that now would be a good time to talk about the benefits of training your lawn.

Lawns and gardens can be water hogs. But experts agree that with proper training, most landscapes should be able to tolerate drought conditions with few problems.

Most lawns only need water up to two times a week in the spring and summer, less if it rains, and less in the fall and winter. The problem is that people start out watering incorrectly so they have to re-teach their lawns to use less water.

With drought conditions in affect for much of the area, now is the time to start re-training your landscape for less water. That means to ONLY water your lawn when it really needs it. According to the Virginia Cooperative Extension, you should water your lawn when it shows these signs of thirst:

A "thirsty" lawn turns from the normal green color to a purple-bluish color. In these areas the grass blades will not spring back if you walk across the lawn and your footprints will be visible. This is the first sign of "wilt" and indicates a need for water.

Here are some more landscape tips to consider during drought conditions.

Refrain from fertilizing – Fertilizing encourages new growth, and new growth is less drought-tolerant. If you do fertilize, use fertilizer with slow release nitrogen in it. If your goal is to improve grass color, try an iron application rather than fertilizer. Dull mower blades can also make your lawn look brown instead of green by shredding rather than cutting grass blades.

Reduce lawn areas– Since Lawn irrigation can account for more than 50 percent of total water use at residential and commercial locations, considering installing a pond, walkway, or larger garden beds in place of water-hogging turfgrass.

Irrigation Methods - Investigate the use of micro–irrigation for your plant beds. Micro-irrigation is more efficient way of distributing water directly to the base of plants without water loss from evaporation and wind drift. If you are in the market for a new irrigation system, find a reputable irrigation contractor who has experience with these systems. If you already have an irrigation system in place, many of the larger manufacturers now sell retrofit kits which will allow you to change specific irrigation zones over to micro-irrigation fittings.

Mulch. Add mulch to plant beds to reduce evaporation from soil and to moderate soil temperature, reducing stress on roots. Make sure to pull the mulch away from tree trunks and plant stems to leave a gap of an inch or two to discourage diseases and insects.

Amend the soil - To improve the water retaining capabilities of soil, considering adding several layers of top-soil or compost.

Weed – Keep weeds under control. Weeds steal water from plants.

Your plants and lawn may seem a little stressed as they adjust to their new watering schedule, but after a week or two, they should adapt and begin to flourish again.

10 Green Tips to Help Save Money in Your Garden

I recently found a great post that helps us do two things we love: spend time in our gardens and save money.

The original post is called 8 ways to save money on costly lawn care and is from the bankrate.com site. What's really cool is that most of the things listed are very eco-friendly, too. I added a few suggestions of my own to round out the list to 10!

Read the full post for more details on their suggestions, which are:

1. Xeriscape your yard - The savings can be big. One estimate by the University of Illinois Extension puts the amount of water a lawn needs to stay green in summer at 1 inch of water per week, which translates to an average of about 2,500 gallons of water per week to keep a 4,000 square-foot lawn green, assuming no rainfall. If you pay $3 per 1,000 gallons, that's almost $400 per year to water your lawn. Xeriscaping cuts that in half, according to the University of Georgia Cooperative Extension, making the savings almost $200 per year.
2. Plant fruit trees - Not only can fruit trees save money by providing shade for your home to reduce heating bills, but they're also a great source of free fruit if properly maintained
3. Compost organic waste - Grass clippings, vegetable scraps and other organic waste can be turned into free compost to augment soil, to mulch around trees and to fertilize your lawn.
4. Plant perennials instead of annuals - Annuals must be replanted every year. Save money by planting perennials that will last three years or more
5. Plant leafy shade trees around your home - Once trees take hold and get big enough, their shade can keep your home significantly cooler and help you save money.
6. Start with seeds and smaller plants - You can cut your costs down by a half to two-thirds if you just buy quart-sized plants instead of gallon-sized containers.
7. Don't replace outdoor furnishings; paint them - You can save money on yard furnishings with some creativity and a little elbow grease.
8. Shop plant sales in the fall - Especially in the northern part of the country, you can save money as nurseries clear their inventory for the winter with plant clearance sales in mid to late fallHere are my extra two suggestions!
9. Participate in conservation rebate programs offered locally - Montgomery County Rainscape program, District of Columbia Smart Homes Program and others.
10. Shop at local thrift stores for garden goodies - Helps keep your garden costs under control while you support local charities.

Gardening good for the body & the soul - Follow Friday Friend

I love garden blogger Kathy Van Mullekom and her Diggin' In blog. I feel like she and I are definitely kindred spirits who enjoy our gardens both for the inspiration that they provide us and for the pleasures of the birds, butterflies and other little critters that share our garden spaces with us.

This exerpt from her recent post entitled Gardening is good: Research links mood to outdoor exercise is a perfect example:

The recent issue of AARP magazine features an article stating new research from England's University of Essex finds that just find minutes of "green exercise," which includes gardening, cycling and fishing, boosts your mood and self-esteem.

This latest research confirms what other similar studies have said: Getting your hands dirty helps you emotionally and physically.

Add a little mediation, or quiet prayer, while you garden and your spiritual side soars, too!

My meditation in the garden happens best when I encounter wonderful little scenes like the box turtle eating my Juliet tomatoes. I love turtles, so I was so happy to see him feasting on the treats. I always plant more than husband Ken and I need, so Mr. Turtle was welcome at my buffet. Read full post here.

Everything that Kathy writes is wonderful. She is definitely another example of my deep research - that "Peter Rabbit's experience aside, gardeners are probably just nicer people."

Drought Alert for D.C. Region

WASHINGTON - The D.C. area's heavy dose of sunshine over the last six weeks has begun to take its toll on the region's water supply system.

The Metropolitan Washington Council of Governments (COG) has issued a drought watch for the D.C. region, asking residents and business to conserve water.

The record high temperatures along with the absence of rain in the area has affected streamflow and groundwater levels throughout the Potomac River Basin. In the last month, precipitation levels are 50 percent below normal.

While water demand decreases as fall approaches, COG wants people to take the appropriate steps to make sure the strain on supply systems is minimal.

"We are encouraging folks, sort of as an awareness step, to encourage conservation now, so if the drought were to persist and become worse, folks are practiced at what to do to conserve water," says COG's water resources technical manager Steve Bieber.

The watch is the second step in COG's four-stage drought response plan. Officials do not anticipate the watch reaching a "warning" or "emergency" phase.

COG wants residents and businesses to use water wisely during their daily routines, including:

• Limiting the watering of lawns, plants and shrubs
• Using a broom instead of a hose to clean sidewalks and driveways
• Using a commercial car wash that recycles water
• Reducing shower length
• Turning off water while brushing teeth
• Washing full loads in dish and clothes washers

If watering your lawn in necessary, Bieber says two waterings a week is enough to sustain its health.

"Measure the water using something simple like a rain gauge or you can even use a tuna can so you know how much water is going on your lawn," he says.

"You want to limit your watering to about one inch a week. Your best bet is to divide the watering of one inch into two waterings per week, typically in the evening, so you are not losing a lot of it to evaporation."

COG also asks people to use extra caution when smoking outside or using outdoor grills due to the fire hazard they present when used around extremely dry conditions.

Protect Your Groundwater Day, September 14

There seems to be a day for everything. And according to the National Ground Water Association (NGWA), September 14th is Protect Your Groundwater Day.

“Every person can do something to protect groundwater in their local area—from not polluting it to using water wisely,” said Cliff Treyens, NGWA Public Awareness Director. “We each have a personal responsibility to protect groundwater. The good news is that for most people all it takes is a small adjustment in their daily habits.”

On Protect Your Groundwater Day, NGWA urges you to ACT.

ACT —acknowledge, consider, take action.

Use this day to begin doing your part for protecting one of our most important natural resources — groundwater!

1. Acknowledge the causes of preventable groundwater contamination and water waste. Remember, any chemicals used in your yard have the potential to wash into storm drains and pollute local waterways —

• There are hazardous substances common to households
• Most household water use occurs in a few areas around the home.

2. Consider which apply to you —

• What specific hazardous substances are in and around your home?
• Where do you and your family use the most water?

3. Take action to prevent groundwater contamination —

When it comes to hazardous household substances:

• Store them properly in a secure place
• Use them according to the manufacturer’s recommendations
• Dispose of them safely.

When it comes to water conservation:

• Modify your water use (more water saving tips)
• Install a water-saving device.
