SMALL SPACE GARDENING: Start this year’s garden with a soil test

Growing a beautiful landscape starts with the soil under your feet. The best place to start building a healthy soil foundation is with a soil test. The results will tell you what type and how much, if any, fertilizer is needed for the plants you are growing. Using the right type and amount of fertilizer is also good for your budget and the environment.

Test the soil when starting a new garden or one that is struggling. Since soil and fertilization practices vary greatly, collect and submit separate samples for each garden bed or landscape area to be tested. Repeat every four or five years to check on your garden maintenance.

You can take a soil test anytime the ground is not frozen and you have not recently fertilized. Early spring and fall are good times since you can make needed changes when preparing your garden.

Contact your local Extension service for details on submitting a sample. If they don’t have a soil testing lab, they will likely recommend a state certified lab that tests home lawn and garden soils, or you can search the internet for a certified lab near you.

Taking a soil test sample is simple. Use a clean trowel and bucket to gather a soil sample.

Slide away any mulch or debris on the soil surface. Use a trowel and remove a slice of soil that is four to six inches deep and right where the plant roots grow.

Take several samples throughout the garden you want to test. Collect samples from each edge and several throughout the middle of the bed. Mix them together and place about a cup of the soil in a plastic bag or the one provided by the lab. Be sure to complete and include the submission form. This includes a place to list the types of plants that will be grown in the area being sampled. The lab uses this and test results to make the fertilization recommendations. Send the sample and form together to the soil testing lab.

Allow several weeks for the test to be completed and the results to be returned. Most basic soil tests report the amount of phosphorus and potassium in the soil. Phosphorus promotes flowering, fruiting, and root development. Potassium promotes drought tolerance, disease resistance and hardiness. Many soils are high to excessive in these plant nutrients. You cannot remove the excess but should avoid adding to the problem. Soil test reports can help you do just that.

Most labs do not measure the amount of nitrogen in the soil since the levels change quickly and are not easy to test accurately. Instead, they make nitrogen recommendations based on the plants you are or will grow in the area being tested.

Soil pH is also measured in most soil tests. Acidic soils with pH below neutral (7.0) are often referred to as sour, while alkaline soils with a pH above 7.0 are called sweet.  Soil pH influences which nutrients in the soil are available for the plants to absorb and utilize for growth. Blueberries, azaleas, and red maples are examples of acid-loving plants. Clematis, crabapples and spireas are a few of the alkaline tolerant plants.

Always use soil test results when trying to change the pH. Lime is used to sweeten soils while sulfur is often used to lower pH. Using too much or the wrong amendment can negatively impact the health and productivity of your garden. Undoing misapplications can take years to correct. Growing plants suited to the soil pH may be the best solution for those with acceptable, although not ideal, soil pH.

Include soil testing when planning new gardens or helping those that are struggling. Understanding your soil can help you create a strong foundation important to the health, longevity and beauty of your gardens and landscapes.

SMALL SPACE GARDENING: Always room for strawberries

As you plan this year’s garden, be sure to include some strawberries. They are low in calories, high in vitamin C and antioxidants, and provide seasonal interest in gardens and containers.

Best of all, you don’t need much space to grow this delicious fruit. There are three types of strawberries: June or spring bearing, everbearing, and day neutral. Select the best type of strawberry for your space and harvest needs.

June-bearing strawberries produce one crop of berries in late spring to early summer, depending on where you garden. They produce the largest harvest but in the shortest span of time. Plant now and enjoy an abundant harvest next year.

Everbearing strawberries usually produce two crops of berries each year. You’ll enjoy fresh strawberries early and late in the season, while day-neutral plants produce berries throughout the growing season.

Delizz®, a day-neutral strawberry, was the first ever strawberry to be selected as an All-America Selections Winner. Just like the flower and vegetable winners, it was tested nationally and selected for its performance for the home garden. This 2016 winner is a compact plant perfect for hanging baskets, containers or garden beds. It can be started from seed or transplants and will produce sweet fruit the first year and all season long, even during hot weather.

Up the ornamental appeal of traditional in-ground plantings with a star shaped or tiered bed. The elevated beds make for easier planting, weeding, and harvesting. You’ll find a variety of tiered shaped beds to purchase or plans to make your own.

Use strawberries as a groundcover in sunny well-drained locations for an abundant harvest. Their attractive leaves, white flowers, red fruit and brilliant red fall color add sparkle to the landscape and provide fresh fruit for your meals.

Or grow them in a container, window box or hanging basket on your porch, balcony, or deck. They’ll be close at hand and easy to harvest.

Mix a few everbearing or day-neutral strawberries in with flowers to create an edible and ornamental planter. The harvest will be smaller when grown in a mixed container, but the flowers, fruit and fall color add ornamental appeal and the fruit will be a welcome treat.

Boost the harvest by growing strawberries in their own container. Fill a hanging basket and watch as the runners cascade over the edge for added ornamental appeal.

Try filling a traditional strawberry pot – container with planting hole openings on the top and sides – with plants that produce several harvests and remove the runners as needed. Keep all the plants from top to bottom looking their best with this DIY watering device. Place soil on the bottom of the container. Set a couple of perforated PVC down through the planter. Slide the plants through the hole from the inside of the pot. Fill the remaining space with soil. Gently tamp and water thoroughly to eliminate air pockets. As you water, the water travels through the pipe and out the holes, providing moisture to all plants from top to bottom.

Check containers daily and water thoroughly and often enough to keep the soil slightly moist. Reduce maintenance and increase success by incorporating a low nitrogen slow-release fertilizer into the soil at planting or sprinkle over the soil surface as needed. This type of fertilizer promotes growth without interfering with flowering and fruit production.

Start now identifying spaces to add strawberries to your landscape, deck and balcony. Then order seeds or plants early for the greatest selection. Before you know it, you’ll be enjoying garden fresh strawberries in your morning cereal, salads or as a snack at the end of the day.
