Attracting Pollinators

Posted on by

Pollinator populations have declined significantly in recent years, mainly due to habitat loss. Homeowners can help by creating pollinator-friendly gardens. Knowing plant traits such as flower color, shape and scent will guide you to which plants to choose for pollinators.

Hummingbirds are attracted to flowers of vivid shades of red, yellow, and purple with a tubular shape that they can access with their long narrow beaks.

Bees prefer purple, blue, orange, or yellow flowers with short tubes or no tubes which they can easily access.

Butterflies are drawn to white, pink, red, yellow, or purple flowers with a place they can perch while sipping on nectar.

Allelopathic Sunflower Seeds

Posted on by

As the weather turns chilly and bird feeders go up, here’s a new word for you…..ALLELOPATHY.

?

Allelopathy is where an organism releases natural chemicals that affect the growth of other organisms. How does this apply to your bird feeder? Sunflower seeds. It turns out that many sunflower species, including those used for bird seed, are allelopathic to many other plants, so much so, that they are used as natural weed control. The chemicals contained in most parts of the sunflower, including the roots, seeds, and seed hulls, naturally block the growth of other plants. Basically, the sunflower wages chemical warfare against competing plants. The main allelopathic chemicals that sunflowers produce are terpenes and phenolic compounds. So, bear this in mind when placing your bird feeder (and when growing sunflowers in your garden). Dropped sunflower seeds and hulls, if allowed to build up under your feeder, will kill off most other plants. Plus, it’s always good to keep the area under your feeder tidy to avoid enticing unwanted visitors like rodents, raccoons, skunks, and more.

Fall Seed Collecting 

Posted on by

Collecting Seeds: Collect seeds that are open-pollinated varieties, which means the seeds being saved will produce plants with the same characteristics as the parent.

Annual flowers: Marigolds, Nasturtiums, Cosmos, Calendula, Snapdragons, Amaranth, Sunflower, Morning glory, Zinnias

Perennial flowers: Rudbeckia hirta (Black-eyed Susan), Echinacea purpurea (Coneflower), Coreopsis (Tickseed), Digitalis (Foxglove), Centranthus ruber (Red valerian), Dianthus barbatus (Sweet William), Aquilegia (Columbine). Continue reading →
