Cherry Blush Rodgersia doesn’t mind wet soil.

The arrival of spring means it is finally time to get back in the garden, but for a lot of the US the soggy conditions are making this impossible. The combination of spring rains and the melting of this winter’s substantial snow has led to a lot of flooding and standing water, which means that for most of us, our soil is too muddy to work with right now. In these soggy months, take this opportunity to evaluate the movement of water through your property and design a garden that goes with the flow rather than against it.

Don’t let your yard become a bog; manage rainwater wisely with this 3-step process: First, observe your property during rain storms and get a feel for how water is flowing through it now. Second, deal with your lawn’s storm runoff and boggy areas by creating a rain garden. Third, improve your land’s dry areas by creating swales and/or xeriscaping.

1. Get the Lay of the Land.

There is no one right answer for how to make the most of rainfall. The answer is always “it depends.” It depends on how much slope there is on your property. It depends how compacted or how well-draining your soil is. It depends how deep your local water table is. It depends how much rain you get. It depends how much water your gutters or driveway are dumping on your lawn. Every situation is unique, so you have to pay careful attention to your yard and find the problem areas that you want to address.

Smart garden designers always evaluate the area and come up with ways to work with the existing water flow rather than imposing their own vision. If you try to add a rain garden or a swale where it doesn’t belong, you might end up with an unattractive mud pit. So be sure to figure out the natural flow of water on your property and develop your plan from there.

The first thing you will probably notice is any areas of standing water. These are usually dips or low-lying areas of the landscape that retain water. These are potential sites for rain gardens or at least good sites for water-loving plants. Look at step 2 for instructions on how to create your rain garden. Next, take a look at areas that are more dried out, where plant growth is sparse. This often happens on the slopes of hills, where all the water quickly drains after rain. Here you can try to improve water retention with a swale, which I will explain in step 3. Xeric plants, which tend to originate from desert-like conditions, are also great for these areas because they are highly drought tolerant. These plants can replace water-thirsty lawns with beautiful perennials that, most years, won’t need a drop from you!

You need to determine two other things about your land that might not be immediately obvious: 1. How good the drainage is, and 2. How high the local water table is. You can determine both of these things with a very simple test: just go out to your back yard and start digging a hole. Make this hole about 1′x1′x1′.

The spot.

1. The Spot.

The Hole (Note the Red Clay)

2. The Hole (Note the Red Clay).

If you hit water, or if the hole begins to slowly fill up, then your water table is obviously very high, and this means it can be extremely difficult to achieve good drainage in this spot. In this case, you could either try and rise above the water table with raised garden beds, or you could simply plant water-loving plants that don’t mind wet feet, like Japanese Water Iris , Rodgersia, Calla Lily, Weigela, Astilbe, Lobelia, and Joe Pye Weed.

4. After 12 Hours of Drainage.

If, on the other hand, you get to a good depth without hitting water, then there is hope. Your standing water is probably just a drainage problem. Next do a drainage test: Fill your foot hole with water and then keep an eye on how long it takes to drain.  If it takes 4 hours or less (about 3 inches per hour), then your drainage is adequate for a rain garden or other planting. If a lot of water still remains after 4 hours, then you need to improve the drainage.

Above you can see my own results for this test. After 4 hours the hole was still about half full, which indicates some pretty poor drainage. If you look at the earth extracted, you can see the  culprit. My yard has that red clay that is prevalent in much of the South–good for staining your car, driveway, shoes, and carpet, but not great for growing plants. The hole  is on a sandier spot, as you can see from the shiny specks in the earth. This gives it SOME amount of drainage–by the next morning (~12 hours later) the hole was drained. To grow anything here, we need to improve the drainage more and add a lot more organic matter: hence the necessity of my compost pile you can see to the left of the hole.

Other ways to improve soil drainage are by adding gravel, pipes, or tile underground and/or by conditioning your soil. Sometimes soil is just compacted and needs worked with a spade or tiller to loosen it up and allow drainage. If the soil has a high clay content (like mine), then you should amend it with compost and/or sand. Another way to improve soil drainage is to add in some Garden Gypsum, which gathers the clay into pellets and allows water and air to flow through.

Next time we will talk about how to create a rain garden, and why you absolutely should!

daffodils-at-Park-SeedWe here at Wayside Gardens (and Park Seed and Jackson & Perkins) are always thrilled by signs of spring in our little corner of the world. So it was especially nice today, after the deep freeze we experienced last week, to see one of the harbingers of spring, the daffodil, show its pretty head near the exit road of our place.

Just what color could they be? I personally don’t know as this will be my first spring with our fair establishment. So I’ll keep everybody up to date as the days wear on. Hang on, neighbors in the north! Hope springs eternal here at Wayside.

An orange-inspired garden design with purple accents.

Click here to see the Pinterest board of the best orange varieties!

We’ve all got our favorite color, that one that just seems to “pop” for us more than all the others. For me, that color is orange; nothing seems quite so vibrant as a bright orange bloom on a sunny day. Whenever I come across a particularly beautiful orange specimen, I just think about how good it would look in a whole orange arrangement. That’s why I put together this garden design to serve as a planner for myself and the other orange-aholics out there.

Year of the Echinacea

Year of the Echinacea

Posted on Feb 11, 2014 | 2 comments

The National Garden Bureau has declared 2014 the Year of the Echinacea, and I say it is about time! Echinacea is one of those rare perennials where the both the petals and the center of the flower are highly attractive, not to mention the fact that they are so easy to grow: these little troopers are so robust and healthy that they are about as close to invulnerable as a flower can get.

Gardeners have a love/hate relationship with winter. The cold is one of the biggest killers of plants, but at the same time many plants have a chilling requirement—having adapted to a cold climate, they now require a certain length of wintery conditions to allow them to undergo the mysterious process of vernalization.
