Container Gardening could be your Answer!

Want to add color to your landscape without fighting Idaho’s heavy clay soil?

Container gardening may be the answer! More than just for areas with limited space, containers are great for adding height in an existing garden, as a way to plant areas with difficult in-ground soil conditions, or as a portable home for plants that cannot survive the winter months outdoors. They also allow gardeners an opportunity to experiment with combinations of colors and textures on a small scale before taking on a bigger planting.

Additionally, I use container gardens within my own landscape in order to create visual levels of plantings within my border, as well as an alternative to battling digging out and amending the hard clay soil.

Key considerations when gardening in containers: 

1. Location: When determining where to place your containers, it is important to consider the amount of sunlight the location gets during the day. 

2. Container: Containers should have adequate drainage and not be too much larger in size (around) than the combined area needed for the plants that will be planted in the container.

3. Soil: The soil should be mostly a potting soil mix, that can be amended with organic material (compost, peat moss). When adding material to the potting soil, the soil and organic material should be well combined in order to have a uniform texture and allow for proper drainage. 

4. Plant selection: Based on the amount of sun that the container will get during the day, select plants that have similar amounts of sunlight and water required. 

How to Design a Container Garden:

Designing a container garden lets the gardener be free to create playful and eye-catching garden spaces. 

The primary design elements of a container garden are the thrill, fill, and spill. 

1. The thrill is usually a planting that creates height in the container, it is a planting that is often centered in the container and is taller than the rest. 

2. The fill is a plant or plants that are similar in height, but shorter than the thrill. The fill occupies the middle section of the container planting and may have pops of color contrast that draw the eye toward the container. 

3. The spill is typically a trailing plant that spills over the side of the container and adds both drama and texture.

It's Summer! Aren't you gladiolus!

No flower is more stunning in an arrangement than the gladiolus. Here's a video from planting to blooms! They are popular cut flowers for all occasions, from weddings to funerals. Though mostly known as a cut flower, gladiolus look beautiful in the flower garden as well, especially when grouped together and planted next to complimentary flowers. Varieties are available in almost any color of the rainbow, with many having frilly flowers and bi-colored blooms. The sword-like leaves yield a spiky flower stalk with individual flowers that bloom from the bottom up.

Gladiolus is an easy-to-grow flowering bulb that produced an abundant display of beautiful blooms for the home garden or for commercial florists. They are also known as Sword Lilies. They are part of the Iris family (Iridaceae). 

Gladiolus range from 2’-5’ tall with graceful trumpet-shaped blossoms borne in a double row along the stem. Flowers come on upright spikes, usually one per corm. Gladiolus grows from a bulb-like underground structure known as a corm. With the onset of spring growth, stems emerge from the corms and give rise to 1 - 9 narrow un-branched, sword-shaped, longitudinal grooved leaves enclosed in a sheath. They will need full sun in moist well-drained soil. Very sandy or heavy clay soils should be amended with organic materials such as compost or peat moss. 

Plant corms after soil warms up in the spring, from mid-April to mid-June. Place corms at a depth of three to four times their diameter, and 4 to 6 inches apart. Work a complete fertilizer. Corms can be planted every 10 to 14 days for a succession of blooms. Corms bloom 65-100 days after planting. Plant the last set to bloom before frost. Gladiolus can be planted in rows but usually will need support. It is important to water gladiolus regularly during growth. Continue watering after flowering as long as leaves are green. Gladiolus thrips are the most common problem and are usually present wherever gladiolus are grown. Thrips feed by rasping the leaves, flowers & corms. 

To save gladiolus corms for next year, dig the corms after the foliage has dried in late summer or fall. Spread the corms out on the garage or storage-room floor and allow to dry for 3 to 4 days. Place the corms in boxes with dry peat moss or sawdust. Store in a dry, cool place at a temperature of 45 to 50 degrees F. Check them periodically during the winter for signs of rotting or rodent damage, and discard those affected. Enjoy!

Invest In Your Health By Growing Blueberries!

Blueberries are one of the healthiest garden planting options. Not only are they highly nutritious, they rank #1 in antioxidant activity (neutralizing harmful metabolic by-products that can lead to cancer and age-related diseases), slow loss of mental capacity with age, reduce cholesterol build-up, prevent infections, improve eyesight, and provide numerous other health and even cosmetic benefits.

Growing this superfood successfully in Idaho does however require a fair amount of effort in planning, preparation, and maintenance

• Select a site with full sun exposure to develop good fruit flavor and high yields. 

• Cool, moist, well-drained sandy loam or silt loam soils with about 3% organic matter and an acidic pH between 4.5 and 5.2 are best. Since alkaline soils are common in southern Idaho, soil acidification with sulfur 1 to 2 years before planting may be necessary. A soil test will tell what you’ll need to do or not do – add limestone to increase the pH or elemental sulfur to decrease the pH and if you need to increase magnesium concentration with potassium magnesium or magnesium sulfate. 

• Highbush varieties can grow 10 feet tall and 6 feet wide and should be spaced 4 to 5 feet apart. Select early, mid, and late season cultivars for optimal yields throughout the growing season. Yields for different cultivars vary from 2 to 20+ pounds per bush so determining how many bushes you’ll need is an important part of planning. On average, 1 pound of frozen blueberries yields 1 pint. I eat ½ pint/day 5 days/week – that math works out to 130 pounds annually for just my breakfast.

• Blueberries are intolerant of standing water and drought conditions so irrigation needs to be installed and operational before planting. 

• For the first two springs after planting, strip off all blossoms to establish healthy canes and increase long-term yields. Afterwards, yearly, moderate pruning in late winter or early spring will maintain health and productivity. Older, dead, or diseased wood should be removed. 

• Organic mulch should be applied to control weeds with any that thrive under the mulch removed by hand or eradicated with glyphosate herbicide. 

• Blueberries are heavy feeders and prefer ammonium sulfate (21% N) fertilization because it not only adds nitrogen but acidifies the soil. Alkaline irrigation water makes regular fertilization even more critical.
  

  

After the planning, preparation, and maintenance effort, it will take 2 to 3 years to get harvestable fruit and 6 to 8 years to reach maximum production, so patience is also required.

Once your bushes are established and productive, preserve your health and harvest off-season by individually quick freezing your blueberry bounty. This and other easy preservation techniques will keep you supplied with superfood all year long. Here's a great jam recipe to try.

No matter how you like to prepare or eat them, invest in your health by making the effort to grow blueberries.

Why Gardening with Native Plants matter.

 Native plants provide many benefits to people and wildlife, while significantly adding to healthier soil and water.  Of the many benefits, my top six motivations for landscaping with native plants include: fewer fertilizers, pesticides, herbicides, and water. Plus, indigenous plants promote cleaner air, food, and shelter for wildlife, and they have proven to save money in many ways.

Excess phosphorus and nitrogen, main components of fertilizers added to our soil become toxic, and the runoff leaches into our waterways, causing excess algae growth. This surplus fertilizer depletes oxygen from our waters, harms aquatic life, and interferes with recreational uses.  Pesticide and herbicide runoff from lawns can contaminate our rivers and lakes with poisonous substances. Native plants have deeper roots and require less water.

As to cleaner air, our native landscapes do not require mowing, and they do not need nearly as much maintenance.  Lawns must be regularly mowed, weed-whacked, and often blown with leaf blowers.  These tools cause harmful emissions and air pollutants like carbon monoxide, carbon dioxide, nitrous oxides, sulfur dioxide, volatile organic compounds, and air toxins like benzene and particulates created from power tools. 

Our native plants attract a variety of birds, butterflies, and other wildlife by providing diverse habitats, food, and pollinator sources. In contrast, non-native plants offer little or no food or shelter to most native wildlife.

Essential to many home gardeners is the need to save time and money.  When compared to the high-maintenance of lawns and the added care necessary for exotic plants, it is easy to measure the economic benefits of landscaping with native plants.  Planting with selective native plants can create a beautiful and scenic landscape.

Shamrock luck!

Shamrocks  are for  good luck and are a popular house plant, especially during St. Patrick’s Day. 

Shamrocks are easy to grow if you follow these five simple and easy to remember steps:

·       Shamrocks prefer direct sunlight, be sure to place your plant in a window where it will receive plenty of light. Shamrocks will flower, even during winter, if they receive enough light. Each night the plant's leaflets fold up , then reopen in sunlight the following day.

·       Shamrocks like food! Fertilize them regularly with either a liquid houseplant or time release fertilizer during their growing season- always following label instructions.

·     As a houseplant, they prefer moist soil. Avoid allowing your shamrock to dry out during the growing season.

·       Give your shamrock a growing temperature between 50 and 70 ^°F during the growing season. They can be placed outside after danger of frost has passed and are a beautiful addition to your pots or in a grouping of pots.

·       Shamrocks have a dormant period. When your shamrock
 goes dormant, usually in late summer, don’t fret! Just place 
it in a cool, dry location out of direct sunlight for 2-3 months. The purple-leaf types only need one month of dormancy!

Since your shamrock grows from small bulbs, it's easy to divide and create new plants. 

Here's a short video with how-to steps for propagating. 
Happy St. Paddy's Day to you!

Tomato Types

 What is Determinate or Indeterminate tomato seeds?

Determinate tomatoes are varieties that grow to a fixed mature size and ripen all their fruit in a short

     (image Ida Gold Cherry)
period, usually about 2 weeks. Once this first flush of fruit has ripened, the plant will begin to diminish in vigor and will set little to no new fruit. 

Indeterminate tomato varieties are vining plants that continue growing in length throughout the growing season, which is why you will sometimes see them referred to as "vining" tomatoes, Indeterminate tomato varieties will also continue to set and ripen fruit throughout the growing season, until the plants are killed off by frost.  

Both determinate and indeterminate tomato varieties have their pluses and minuses. It really depends on what you are going to be using the tomatoes for and also, how long is your growing season. If you want a thick tomato for making sauces, you are better off with a paste tomato and those tend to be determinate.

If you tend to eat your tomatoes fresh and want a season-long supply, go for indeterminate varieties.

An heirloom tomato (also called heritage tomato) is an open-pollinated (non-hybrid) heirloom cultivar

of tomato. Any tomato that is at least fifty years old and is not a hybrid. According to tomato experts, heirloom tomatoes can be classified into four categories: (image Black Brandywine)

• family heirlooms,
• commercial heirlooms,
• mystery heirlooms, and 
• created heirlooms.  

They usually have a shorter shelf life and less disease resistance than hybrids bred to resist against specific diseases. They are grown for a variety of reasons, such as for food, historical interest, access to wider varieties, and by people who wish to save seeds from year to year, as well as for their taste. "Heirloom Tomatoes". Spiritfoods. Archived from the original on 22 February 2013. Retrieved 24 August 2012. 

When the plants of an open-pollinated variety self-pollinate, or pollinated by another representative of the same variety, the resulting seeds will produce plants roughly identical to their parents.

 Hybrid tomato – A tomato bred by crossing varieties. Hybrids offer better disease resistance, higher

yield, and other improved traits.

Early variety – A tomato that matures in 50 to 60 days; these are prized for early harvests and late summer planting for a fall crop. Sometimes we refer to tomatoes that mature in more than 60 days as “early,” but only in comparison to their peers. For example, the earliest beefsteak type is only early compared to other beefsteaks. Beefsteaks are typically longer maturing than other tomato types because they are so big! 

Tomato Disease Resistance Codes 

Tomato names are often followed by capital letters that stand for resistance to certain diseases. This is very important because these diseases can wipe out a tomato crop. 

Xeriscape not ZEROscape

Drought tolerant landscape doesn’t have to mean gravel, and spiky gray plants. Xeriscape (xeri=Greek for dry and scape=view) emphasizes the use of drought tolerant plant species combined with creative landscaping practices to conserve water.

The following terms: water-wise, drought tolerant, water thrifty, and water smart all refer to plants requiring less water in a managed landscape. We all want to use less water in our landscapes and don’t want to be that house with the ugly brown yard.

Whether you have established landscape or total do-over, take a look at the following Eight Principles of Xeriscape:

1. Plant and Design comprehensively from the beginning.

• Lower your water bill.
• Create a more interesting landscape. Plan your annual flower and vegetable gardens and create a planting guide.
• Invite more pollinators into your landscape.
• Don’t just plant and hope for the best
• Create a landscape plan. Identify all the plants in your landscape, their water, sun, and soil needs, and the seasonal maintenance for those plants.
• Record the micro climates in your landscape. Record the plants you add and take out of your landscape and why. Record monthly and annual tasks to remind you when to perform them.
• Develop a fertilization and mulch plan.

2. Create practical turf area. Consider size, shape, and appropriate grasses. Turf uses the highest percentage of water. When planning, consider regionally appropriate turf. Sheep’s fescue (Festuca ovina), and Buffalograss (Bouteloua dactyloides) are two examples of grasses that require less water and grow well in the Treasure Valley. Raise mowing height to 2-4 inches on your mower. The taller grass shades the ground so slows evaporation and promotes deeper root growth. Research shows mulching the clippings instead of removing them, can replace one application of fertilizer per year.

You might consider replacing some of the grass with a  more planting beds for flowers or vegetables. Don’t forget to check your HOA rules when considering the removal of turf.

3. Choose plants for your growing zone.
Once established, regionally appropriate native and low water use plants require little water beyond the normal rainfall (about 12 inches per year of precipitation in the Treasure Valley with 5 of those inches between April-October. Consider soil type, exposure to sun, and choose the right plant for those conditions. 

4. Consider improving the soil with organic matter.  Healthy soil retains water and absorbs excess nutrients, Have your soil tested for nutrient content, PH, soil composition and organic matter. The report will give you suggestions for adding anything that is lacking.

5. Strongly consider using organic mulches such as wood chips.  Adding mulch controls weed growth and slows evaporation, so conserves water. 

6.Irrigate efficiently. Create zones to provide the right amount of water at the right time by grouping plants according to their water needs. Your tree, shrubs, flower and raised beds have different water requirements than your lawn. Consider drip irrigation or soaker hoses for flower beds, shrub and trees. More targeted watering cuts down on weeds and uses less water.
Avoid sprinklers that produce a fine mist or spray high into the air in order to reduce water loss from evaporation and wind.  To check your sprinkler output, use tuna cans or similar straight-sided cans placed at various places around your lawn.  Run lawn sprinklers for 5 minutes and measure the output.  Now calculate the time needed to get  1 inch of water per week on your turf.
Water requirements change often so don’t just set automatic systems and forget them. Review the water requirements often taking into account rainfall, temperature and wind. Adjust the time you water accordingly.

7. Water Harvesting. Direct your roof water into rain barrels or onto your landscape. This recharges Idaho's aquifers as well as irrigating our arid environment. Here's how to build a rain barrel.

8. Maintain your established landscape.  Learn how to prune and fertilize each plant in your landscape and record the requirements in your maintenance schedule.

.Consider visiting xeric demonstration gardens in the Treasure Valley area. Hopefully they will inspire you to improve water conservation in your own home landscape.

The Idaho Botanical Garden has several gardens within its footprint, including The Water Wise Garden and The Fire Wise Garden.
