Create a Natural Prairie Garden By Repurposing Old Lawn Soils

The first settlers of the American prairie could not farm the land. First they had to strip away thick sod layer to expose this extraordinarily fertile soil. Sod was so dense, the slabs were stacked into earthen houses known as “soddies” on the open range. But the sod held more than grass, it was its own natural prairie garden that included a wide range of large prairie perennials.

This is the origin of our easiest and most magnificent perennials. Among them are purple coneflower, black-eyed Susan, blazing star and Joe Pye weed. All of these evolved to live in concert with our native bunch grasses to create prairies that range from very dry (mesic) in the south and the verdant tallgrass prairie in the north. There is no better model for switching out your lawn to a beautiful, natural prairie garden that lures wildlife and provides vital backyard habitat.

The problem is that turf grass lawns are a heavy feeding monoculture that depends on synthetic nitrogen fertilizer to maintain its beauty. Strip away this turf and what’s left beneath is ground worn out by chemical fertilizers much like the cotton fields of the South that were so lean newly freed African Americans could barely eek out a living. These worn out soils starve the microbes to death due to lack of organic matter. That’s why it’s so important to beef up that former turf grass ground to make it more fertile and supportive of a natural prairie garden.

Whether you’re planning a prairie, food garden or a new landscape, that soil must be very well amended if it is to grow a variety of plants again. You’ll want to provide amendments that do three things: boost nitrogen, introduce new microbes and provide plentiful organic matter to feed the microbes.

Because turf grass acts as a barrier, this heavily compacted ground has not experienced new organic matter for many years. Your first step is to turn every inch or rototill to aerate the ground. Then add Black Gold Garden Compost Blend, which are rich in humus. Be generous with these rich materials and work them in as deeply and thoroughly as you can. Remember, this is food to grow your microbe populations.

To compensate for nutrient deficiencies, particularly nitrogen, use potent organic fertilizers. To really boost the nitrogen levels in year one, use fast acting alfalfa meal. Then add a good all-purpose fertilizer to increase your phosphorus and potassium levels. Finally, distribute Black Gold Earthworm Castings for its heavy load of microbes ready to feed on all that new organic matter.

The sooner you apply this prescription the better your new, natural prairie garden will perform. With each month that passes it will grow progressively more fertile. You can plant the beautiful perennials and grasses right into the newly amended soil, or start a new food garden right in your own ground.

This preliminary soil work is vital for anything you plan to grow in lieu of lawn. Such a formula turns secondary earth into first class agricultural soil much like that ground that grew the first incredible bumper crops of corn and wheat. So whether you wish to look out on a flowering prairie or a garden filled with organically grown vegetables, all that’s required is to rehabilitate the soil and Mother Nature does the rest.

Celebrating with Spiral Topiaries

Double Spiral Topiaries - Maureen Gilmer
Double spirals are rare but obtainable from any garden center that carries Monrovia plants.

Nothing gives an entry more pizzaz than a pair of spiral topiaries flanking the front door. Plant them in a beautiful large pot and you’ve got the start of a truly elegant winter display.

Spirals are truly unique in the world of topiary because they don’t resemble the Asian bonsai styles or those poodled into balls. They’re tall and narrow, fitting nicely into corners and small spaces. Spirals are distinctly European in character and therefore they are an easy fit for virtually any traditional home style.

Potted Spiral Topiaries - Maureen Gilmer
After the holidays, move your potted spiral topiaries into the garden where they receive plenty of light on all sides to maintain their symmetry.

When the holidays roll around, spirals are the queens of decor because their corkscrew shape lends itself to strand twinkle lights. This shape also provides flattish spots where you can attach fruit or ornaments that completely transform them. When you have a pair, decorating yields even more glitz, and for a holiday party few other plants create such instant upgrade.

This year may be the perfect time to invest in a spiral at your house in lieu of the traditional holiday cut tree. This is a great investment that can be moved outdoors as a winter focal point after the new year if the climate is warm enough. There is nothing more lovely than topiary under snow.

Choose a spiral clipped from junipers since these are very drought and disease resistant, adapting to nearly all climate zones. These are sold in five gallon pots, or consider much larger pricier specimens that make great Christmas trees.

To create a pair to use outdoors, find large durable decorative containers that suit your home style. The interior and mouth of the pot must be large enough to hold the root ball with plenty of room to spare on top and sides. When the spiral sits in the pot with plenty of edge (freeboard) left at the top, you can fill it to the brim with water and move on, saving a great deal of watering time. In between tuck moss into the space to make it appear full.

Single Spiral Topiaries - Maureen Gilmer
Behind this huge single spiral is a field of Monrovia evergreens waiting to be clipped into spirals.

Since spirals are long-lived, woody trees, make sure you use Black Gold Moisture Supreme Container Mix with controlled release fertilizer (CRF). This slow release nutrition helps get your spirals off to a vigorous start. With topiaries, the strength and color of growth is essential because you must clip more often for a dense, and precise form.

Water generously after planting to coax roots out of the old pot shape into this new, organic soil. There is no better way to obtain rich, luxurious green color in your spirals.

These are sun loving plants, so life underneath the porch is ok in the dead of winter, but it won’t suit them in the growing season. The side that doesn’t receive enough light won’t grow, it may even shed foliage or turn yellowish over time. This is a disaster with topiaries like this which must remain perfectly symmetrical to maintain their beautiful form. Relocating with the seasons is easy if you have a dolly or set the pots on casters.

Whether you buy one, a pair or a whole row of them, spiral topiaries are the most versatile of all evergreens. They can transform a space overnight with their pronounced graphic forms. They’re as suited to Mediterranean architecture as they are American colonial, and even find a home in Spartan modern landscapes too. Just remember they aren’t furniture, but real live living plants, so make sure you give them quality soil and plenty of water. Then get yourself a sharp pair of clippers to enjoy the age old tradition of shaping evergreens all year around.

Growing Coast Redwood In Wet Years and Drought

Growing Coast Redwood - Maureen Gilmer
Redwoods: These nursery grown redwood trees are thriving in a backyard where the ground beneath is filled with azaleas and other forest floor acid loving plants, but as the trees mature there will be too much shade to grow much except ferns.

I have lived among coast redwoods all my life, from college days on the northern California coast to years in design offices – specifying them for use in our projects. From spending much time within expansive old and second growth groves I’ve learned exactly what these tallest of trees desire and what not to do when growing coast redwood. They indeed prove far more adaptable than most realize, and this is a fine evergreen for any landscape. In a year when other states are experiencing droughts on the scale of California’s annual dry season, this tree presents a beautiful, evergreen solution for water-challenged gardens – even those well beyond this state’s borders.

Colorful Foliage Plants for Elegant Autumn Designs

 

Coleus Low - Maureen Gilmer
Coleus: Use annual coleus for incredible color and variegation in fall compositions.
Shield Low - Maureen Gilmer
Shield: My favorite, the Persian shield is the best purple foliage pant for fall and winter color.

Now that the humidity has passed and it’s okay to go outside, why not spice up your patio or entry with some cutting edge color. This time forget the flowers and try colorful foliage plants that bear beautiful leaves with vivid designs. These are bright and brilliant without waiting for blooms, and when the cold of winter sets in they are easy to bring indoors to brighten rooms during the dark days to come.

So dump out those worn out summer pots and lay in some bags of Black Gold Natural and Organic Potting Soil Plus Fertilizer and start turning your patio or front entry into an elegant autumn design statement. The controlled-release fertilizer in this soil will keep your fall-planted compositions carefree and well-fed for the next few months.

Persian Shield

I’ve fallen in love with Persian shield (Strobilanthes dyerianus), my favorite new plant with its rich purple leaves and dramatic venation. These are truly fabulous in low light or bright sun and can develop into large plants in a short time. While not particularly frost tolerant, they make a superior interior accent too, so I’m inclined to spend more for a strong houseplant later one. You can plant this one alone or combine it with succulent sanseveria, the old mother-in-law’s tongue. The two together are decidedly modern in sleek containers or look exotic and tropical in a bamboo basket cachepot.

Coleus

Persian shield can also be grouped into a large color bowl with coleus. This is one annual that has exploded from a few colors to a whole rainbow in just a few years. When you choose an exotic pink to match that purple shield leaf, you’ve got an outstanding focal point for the patio. Later on it comes in to winter over in that sunny corner by the window.

Heuchera

Whenever you can buy a perennial that performs as well as an annual, you get top value for your dollar. Heucheras are another plant that’s exploded as a foliage accent. These small mounts of brightly colored leaves in a rainbow of hues are equally fabulous in pots as they are in the border. They are renowned for retaining their leaves throughout mild winters, so in pots they give you a long span of performance. Plant vivid heuchera varieties into your fall foliage compositions and you’ll have much larger specimens by spring to transplant into the garden.

Dwarf Fountain Grass

A final option that adds fine texture and animation to larger autumn pots is dwarf purple fountain grass varieties. These smaller hybrids with their maroon foliage will be in bloom by early fall, and their arching stems that bear fuzzy lavender-tone blooms sway and nod in the autumn breezes. Use one as the center piece of a rusty, iron pedestal urn with the dark beauty of heuchera, coleus and Persian shield for an upscale, eye popping display to welcome visitors over holidays and special occasions. Plant a pair of them to flank your front door, sheltered under the porch or at your entry steps to create dynamic symmetry.

No matter how you mix and match, these colorful bedding plants provide fabulous foliage and are always a winner. They’re all pest and disease resistant so they don’t need coddling. There are no flowers to snip off so just enjoy the foliage until nights become too cold. Then bring these mature creations into your home to keep those vivid leaves happy and healthy all winter long.

Fight Chlorosis with Earthworm Castings Tea

 

Cure Chlorosis - Maureen Gilmer
The foliage of this squash plant shows varying degrees of chlorosis compared to a few normal, all green leaves. Note the green veins within the yellow leaves that distinguishes nutrient deficiency from pests and diseases.

My squash are screaming at me from the back of my garden in the silent language of plants. The big green leaves of my most productive summer squash are turning yellow. This isn’t a water problem because there is no wilt. Closer inspection of the leaves reveals no pests either. Only the veins of the leaves are still green. This condition is called chlorosis, and it can strike virtually any plant that’s experiencing a nutrient deficiency. But don’t let it get you down. Let’s learn more about the condition and how to cure chlorosis with earthworm castings tea.

Plants need two types of nutrients to grow. First are the macro-nutrients we all know from fertilizer packages, which are nitrogen, phosphorous and potassium. These also include to a lesser extent, calcium, magnesium and sulfur. The list of micro-nutrients is much longer, but these are all needed too, often in small quantities and sometimes just a trace. Among the most vital are boron, iron, manganese, zinc, copper, molybdenum and chlorine. The absence of any of these can cause chlorosis.

The actual nutrient deficiency I’m experiencing may be impossible to nail down exactly, and that’s not really necessary to solve the problem. Often folks assume it’s a nitrogen deficiency, but in my case all the other plants around that squash are nice and green, so that isn’t it. Plus, adding nitrogen rich fertilizer to green-up certain summer vegetables is not the best idea. Those that produce their crop via flowers and fruit such as cucumbers, tomatoes and peppers, may stop flowering, which means no more fruit. Sure they’ll grow big and leafy as a result, but that will interfere with future yield.

The best way to rescue a chlorotic fruiting vegetable plant is to provide a multi-vitamin approach that brings a wide range of macro and micro nutrients into the root zone at the same time. However, for rapid uptake, it must be in a form that’s immediately available to the plant.

Black Gold Earthworm Castings are an all organic fertilizer-like material that is renowned for containing a wide range of macro- and micro-nutrients. That’s why it’s present in many other Black Gold products too. What makes earthworm castings so great is that these nutrients are held in a water soluble form. When applied in a water solution, they enter the root zone and are taken in by that hungry squash immediately.

How To Make Earthworm Castings Tea

If you’re experiencing chlorosis, or a plant that’s simply a poor-doer, create a tea out of earthworm castings and pour it directly onto the root zone of your plant. Though nutrient-rich, there’s no risk of burning the roots. Simply mix one cup or more of earthworm castings into one gallon of water. Be sure to mix again just before you pour it onto your plants to make sure any settled nutrients are again in suspension for even distribution.

Chlorosis in your leafy vegetables such as lettuce or cabbage is treated slightly differently. With these, lots of leafy growth is desirable since this is the part you eat. For these, work in a quality tomato and vegetable fertilizer, then water it in with earthworm castings tea to make sure you’ve covered all he bases. Since all these are OMRI listed, you can confidently apply your nitrogen to leaf crops at any time during the summer or fall season.

Gardening is about recognizing the silent language of plants and interpreting what it means. When leaves turn yellow, be sure to note whether the veins remain green to determine if it’s chlorosis or something else. Then consider if it’s a crop that depends on flowers, or one that’s foliage-based. That tells you exactly how to treat them with confidence using Black Gold all organic fertilizers and potting soils.

Bone Meal: Key to Perfect Tulips

If you dream of the Dutch fields full of perfect tulips but find your fall-planted bulbs disappointing come spring, then maybe your bulbs are just hungry. While bulbs are rather self-contained little packages, the one thing they can use during the long winter is phosphorus and lots of it. This macro-nutrient drives root growth which helps your bulbs become better established come bloom time. The age-old organic way to get it is with bone meal. Dig your hole, then loosen the soil at the bottom, add one tablespoon of bone meal and mix well. Then set your big, juicy tulip bulb onto this soft enriched earth and cover it up. For smaller bulbs use a half tablespoon. Remember, this nutrient doesn’t move much so if you don’t put it down there, roots won’t find it.

From Desert Dry Wash to Organic Vegetable Garden in One Season

Dry Wash into Organic Garden - Spring 2012 - Maureen Gilmer
Spring 2012: The garden in February 2012 – just prior to final fertilizer application with protective bird netting and straw bale barriers against voracious rabbits.

Last year my desert dry wash was nothing but porous sand and decomposed granite. They said I’d never grow organic food there. I had one year to build this ground spring planting season. Here’s how I solved the problems and grew this fabulous 10′ by 20′ organic vegetable garden using Black Gold products…
