Dry River Beds – Beautiful & Beneficial

With so many people replacing their thirsty lawns with low water-use plants, I?m getting lots of requests for ideas about what to do with all that empty space. The sky?s the limit when you have a blank slate. Let me get you started.

If your old lawn was in the front you might consider putting in a sitting area for a couple of chairs and a bistro table. Use simple crushed gravel or more formal flagstone underfoot and surround the space with a low seat wall to add a bit of privacy.

Adding a dry river bed is another good solution. A dry river bed can slow runoff, spread it out and sink it back into the soil. Connected to a downspout they keep even more rainfall on your own property. If we get the El Nino storms that are predicted this will be a welcome addition to your landscape.

runoff to soak into the ground. Make sure there is a 2% slope from beginning to end to ensure that water is conveyed away from your house to the desired location. Non-woven geotextile fabric is often used underneath the rock.

You can create a depression or rain garden at the end of your dry river bed and plant it with plants that tolerate wet feet in the winter. Both a dry river bed and a rain garden allow water to sink back into the ground. The plants remove pollutants from the runoff from roofs or other impervious surfaces.

A rain garden might be a simple, shallow depression filled with plants that can flourish in both moist and dry conditions. The size and depth will depend on your how much water you need to capture in a winter runoff

Sometimes a dry river bed will receive so much runoff that a dry well or dispersal pit is installed at the end. If you have a high water table or clay soil the water may not always soak in fast enough and an overflow device like this is needed. The goal is to keep water on your own property and not in the street or the neighbors? yard.

There are good looking dry river beds as we?ll as bad looking ones. A quick Google image search will show you what I mean. Your goal is to create something that looks like it belongs right where it is. The plants, the accent rocks, the cobble, the location – all need to work together.

If your property has a natural slope follow the natural terrain if possible. You can install a dry river bed on flat land also by creating a channel for the river bed to follow. Keep in mind that even a dry river bed is more interesting if it is not all visible at once. Soft, flowing curves and bends create a natural look.

Start with the rocks and cobble. Rounded river cobble looks most natural for the creek bed. In nature, water flowing down a river would round off sharp rock edges to produce cobble of different sizes. A river never has just one size of rocks and yours shouldn?t either.

Accent rocks can be any type that you like as long as you get a variety of rock sizes and shapes. Use the larger stones to direct and channel water. Placing rocks on the outside of a curve creates a more natural look.

As in all gardens there is always a bit of maintenance to keep things looking and working great. Weeding in the first couple of months while plants become established is important. Replenish mulch as needed until the plants grow in.

Periodically remove leaves that have landed in your river bed and reposition rocks moved by runoff to keep your dry creek bed working for you when you need it. Also don?t start your dry creek bed too close to the foundation of your home if that area is flat. You can direct the water through a drain pipe connected to a downspout to a lower starting spot in your garden.

So whether you are adding a dry river bed to add interest to your lawn-free landscape or to double as catchment for winter storm runoff, make yours look like it?s always been there.

The Garden of Our Dreams vs The Real World

polygala_Petite_ButterflyWith our gardens coming to life at this time of year we are hopeful that each plant will achieve its full during this growing season. But that doesn?t always turn out to be the case and sometimes it?s hard to figure out what exactly is the problem. Growing plants isn?t an exact science. What works over at the neighbor’s yard doesn?t always apply to ours. What are the different factors that can make a plant thrives or just mope along? And how can you plan when one ?reliable? plant source says the plant will get 6 ft tall an another shows that same plant as reaching 8-12 ft tall and just as wide?

When designing a garden whether it?s a client?s or my own I need to take lavender_West_Zayanteinto account the growing conditions such as soil type, nutrients, water requirements, high and low temperature, space and light. Most all plants use water to carry moisture and nutrients back and forth between the roots and leaves. Some need more water than others to do this but all have their own levels of tolerance. Too little or too much water or nutrients can be harmful to your plant?s progress.

Healthy soil provides an anchor for plant roots and helps support the plant in addition to providing nutrients. Healthy soil contains micro organisms and adding organic matter to your soil when you plant and in the form of mulch will increase your soil?s fertility.

Choosing the right plant for the right spot is another important factor but how can you determine if your garden has the right amount of sun or shade or moisture? In our area a good rule of thumb in deciding if your plant is getting enough or too much sun is to look up during the growing season and see how many hours of sun, part sun, bright shade or partial shade your area is receiving. To simplify, it?s not as important what is going on during the winter but knowing the summer conditions is crucial. Too little light can make plants weak and leggy looking with few flowers or fruit.

Allow enough space for your plant to grow. Plants can become stunted without enough room to grow and overcrowded plants often get diseased when air doesn?t freely flow between them. There?s a difference in a plant that just needs a little time to kick in and really start growing and one that is not thriving. Be patient.

Plant your new addition correctly. When digging the hole be sure that you loosen surrounding soil 2-3 times the width of the root ball. There is no rule that you can?t loosen the soil even wider around your planting hole. Use the shovel to loosen the edges of the hole so that it?s not hard and smooth. Roots have an easier time of growing out from the initial hole is sides aren?t hard as a rock. You can loosen the soil below the depth of the root ball if it?s really hard and amend it also. Be sure to firm the soil underneath the plant so the crown of your plant doesn?t sink below grade and drown during winter rains or watering. Planting a bit higher than the surrounding soil also allows for a 2? thick layer of mulch.

If you have a steep hillside, a super sunny or deep shade location or problem soil all the above tips are important for your planting success.

Creating Atmosphere in the Garden

Pride_of_MadeiraSummer may be winding down but we still have lots of great outdoor weather to enjoy for several more months. This means more time to spend outdoors in the garden relaxing, entertaining and cooking on the grill. I like the relaxing part most of all so it?s important to me that what I see and feel when I?m out in the garden have an atmosphere that appeals to me. Here are a few ideas that I?ve used in my own and other people?s gardens I?ve helped to create.

Outdoor spaces are just more inviting if they feel like a real room with a ceiling, walls and attractive flooring. An arbor or pergola is a good way to provide a lid on your outdoor space. If you have natural trees in your garden they can shield you from the sky in some areas and open up other areas to passing clouds and sun. You can achieve a similar effect with groups of potted trees that shade your sitting area. Japanese maples, ornamental plums,cherries or crabapple are just a few of the trees that do well in pots. If you like to grow edibles plant a fig in a pot to provide some shade.

The sounds you hear while in the garden are part of the experience, too. The atmosphere just wouldn?t be the same without the sound of rustling grasses, wind chimes or birds splashing about in the bird bath or fountain. Auditory elements can come from the sound of gravel crunching underfoot as you walk or the wind in the trees.

Create the atmosphere you like by using the colors and textFlowering_Mapleures you most admire in your garden. I use to live in a lot of shade so white, silver and gold foliage and flowers were really important to bring life to the garden. I still love these shades but cool blue, baby pink and soft yellow also appeal to me.

Texture in the garden refers to the overall visual texture of the plants. Large and bold foliage like Flowering Maple, Pride of Madeira, rhododendron, viburnum, oakleaf hydrangea or hosta make a large garden appear smaller. Soft, fine foliage will make the garden appear larger by giving it the allusion of more space. Examples of finely textured plants include ornamental grasses, Breath of Heaven, ferns and asters. You might use different textured plants in different parts of your garden to get the affect you like.

Blur the garden?s boundaries to make it more interesting. You won?t be able to see the whole Breath_of_Heavengarden at one glance if you curve the path behind some shrubs, tall plants or sheer, see-through perennials. Leave some wild areas for the birds and bees to join you. Garden organically and mix in native plants wherever you can to keep the garden healthy.

Creating atmosphere in the garden is the art of combining space and time, light and weather to make a garden that we feel reflects who we are. It?s different for every gardener. One person might like straight rows of vegetables while another scatters poppies and nasturtiums randomly. Whatever appeals to you it should be close to your heart and that?s the atmosphere in your garden that?s right for you.
