Adding Milkweed to your Landscape

There was a time that it was common to see milkweed growing alongside ditch banks in the farming areas of Idaho. As housing developments replaced farm lands the ditch banks disappeared and the use of chemical agents became more common. You may ask, “Who cares?”  If the monarch butterfly could talk to us, you can be sure they would say that they care. Monarch butterfly larvae, or caterpillars, feed exclusively on milkweed leaves. Without the milkweed host plant the larvae are unable to develop into adult butterflies. 

Members of the community who enjoy the presence of butterflies and understand their value as pollinators also care. Recognizing a fall in the population the U.S.Fish and Wildlife Service applied for endangered species protection for the Monarch butterfly in 2014.

A large part of the effort to support monarch preservation is providing milkweed plants to replace those that have been lost in the environment. It is important to use milkweed native to the area in which you live. Milkweed creates toxins. Monarch butterflies have used these toxins to their benefit as anti-predator and anti-parasite defense. Milkweed plants that are not native to an area can contain larger amounts of the toxins and create harmful levels for the monarchs.

The state of Idaho has 6 varieties of milkweed native to our environment according to the Idaho Native Plant Society newsletter.

Antelope horn milkweed  (Asclepias asperula)  is found in southern Idaho, especially in the Preston area.

 

  

 Pallid milkweed (Asclepias cryptoceras) is found on clay or gravelly soils in southwestern Idaho (Owyhees) to Utah.

Narrow-leafed  or Mexican whorled milkweed  (Asclepias fascicularis) is found in Idaho’s western Panhandle. Very weedy.

Swamp milkweed (Asclepias incarnata) is common in eastern U.S., also found in Idaho and in Utah.

Showy milkweed (Asclepias speciosa) is Idaho's most common species. It grows up to 1 meter tall with fragrant flowers in late summer. The corona is in the shape of horns, and contains nectares. Each inflorescence usually grows only one follicle (seed pod).

Poison or Horsetail milkweed (Asclepias subverticillata) is a weedy species with small white flowers and narrow leaves.

Seeds for most of these milkweed species can be found from seed vendors on-line. Milkweed seeds are wild seeds. They have evolved to thrive in a natural environment, not your backyard. The seeds  require conditions that mimic environmental conditions to germinate. The LadyBird Johnson Wildflower Center has developed and tested a protocol that results in good germination rates for native milkweed species. The process involves four steps that take 4 to 8 weeks to complete. So start now!

Recognizing the importance of the monarch butterfly, a partnership of federal and state agencies, non-governmental organizations, and academic programs, The Monarch Joint Venture, has been working to support the goals of North American Monarch Conservation Plan. They provide educational resources to the public about Monarchs and Milkweed.

MonarchWatch is another resource for the gardener interested in supporting and attracting pollinators. They offer guidelines for gardening methods that support Monarch butterflies and offer Monarch Waystation designation when their guidelines are followed.

The addition of milkweed to the milkweed to the environment around your home will provide needed host plants for Monarch butterflies. When nectar producing plants are also added your landscape can attract a variety of pollinators. Successful gardening is a partnership. The gardener provides the plants needed by the pollinators to survive and the pollinators give the gardener new seeds to continue the process.

Soil blocking for your Spring Seed Starting

Soil blocking presents several advantages for home gardeners, making it an attractive option for those seeking efficient, sustainable, and rewarding gardening practices.

Space Optimization: For home gardeners with limited space, seed blocking offers a compact and efficient way to start seeds indoors. By using soil blocks rather than traditional pots or trays, gardeners can maximize their growing area and cultivate a greater variety of plants in a smaller space.

Cost-Effectiveness: While initial investment in seed-blocking equipment may be required, the long-term savings are significant. Soil blocks can be made using simple tools or purchased commercially, eliminating the need for disposable seed trays and pots. Moreover, seed blocking reduces seed waste by ensuring each seed is planted with precision, saving money on seed purchases in the long run.
Improved Seedling Health: Seedlings grown in soil blocks tend to experience less transplant
shock compared to those grown in traditional seed trays. The intact soil blocks protect delicate roots during transplanting, resulting in healthier, more resilient seedlings with higher survival rates.
Water Efficiency: Soil blocks retain moisture more effectively than traditional planting 

mediums, reducing the frequency of watering needed for seedlings. This is especially beneficial for home gardeners who may have limited time for watering or live in regions with water restrictions.
Ease of Transplanting: Transplanting seedlings from soil blocks is straightforward and minimizes root disturbance. Gardeners can simply place the soil block directly into the planting hole, eliminating the need to handle delicate seedlings or disturb their roots. This reduces transplant shock and ensures a smoother transition to the garden bed or container.
Reduced Disease Spread: Traditional seed trays and pots can harbor pathogens and promote the spread of soil-borne diseases. In contrast, soil blocks are less likely to harbor harmful microbes, reducing the risk of disease transmission among seedlings. 

Environmental Sustainability: By reducing the use of plastic pots and trays, as well as minimizing seed and water waste, seed blocking aligns with environmentally friendly gardening practices. Home gardeners can feel good about minimizing their ecological footprint while enjoying the benefits of healthier plants and bountiful harvests.  

Summary: Soil blocking offers home gardeners an array of benefits. With its simplicity and effectiveness, seed blocking is an excellent choice for gardeners looking to maximize their gardening success while minimizing their impact on the environment.

Shamrocks - So Many Lucky Choices...!

 Shamrocks have long been a symbol of 
Ireland and have even been considered a symbol of good luck. They are popular houseplants and fun gifts for friends and neighbors on St. Patrick’s Day. Shamrocks are easy to grow indoors if you follow these simple and easy to remember steps:

Light
Shamrocks prefer bright, indirect 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.

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

Iron Cross Shamrock

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

Temperature
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.

Dormancy
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 is easy to divide and create new plants. Here's a short video showing how to propagate shamrocks.

Happy St. Paddy's Day to you!
