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.

Cleaning Your Garden Tools

Posted on by

Initial Cleaning

  • Remove Loose Debris: Use a brush or a stiff brush to remove any loose dirt, leaves, or other debris
  • from your tools.
  • Wash with Soap and Water: Dip the tools in a bucket of soapy water (dish soap or detergent) and scrub thoroughly to remove dirt and grime.
  • Rinse Thoroughly: Rinse the tools under running water to remove all soap residue.

Disinfection (Recommended):

  • Bleach Solution: For a quick and effective disinfection, soak the cleaned tools in a chlorine bleach solution (1 part bleach to 9 parts water) for about 10 minutes, then rinse and dry thoroughly.
  • Alcohol Solution: Isopropyl alcohol (70-100%) can also be used for disinfection. Dip the tools in the alcohol solution, allow them to air dry, and then dry the tools thoroughly.  Add Isopropyl alcohol into a handheld sprayer and spray shears between each plant you prune.

Rust Prevention:

  • Dry tools:  Completely dry tools before storing them, otherwise moisture can lead to rust.
  • Apply Oil: To prevent rust, apply a thin layer of mineral oil, linseed oil, or WD-40 to metal parts, especially after cleaning.
  • Soak in Sand: For a quick way to clean and oil tools mix some linseed oil in a bucket of sand and then stab the tool into the sand a few times.

Specific Tool Cleaning:

  • Pruning Shears/Pruners: Disassemble pruners, wash each part individually with warm, soapy water, and scrub any sap or sticky residue left behind.
  • Disinfect Pruning Shears: Add Isopropyl alcohol into a handheld sprayer and spray shears between each plant pruning.

Cultivation Tools (Spades, Hoes, Forks, Rakes, Trowels): Use a stiff scrubbing brush to remove any soil from the blade and shaft.

Rusty Tools: Soak rusty tools in vinegar for several hours to loosen rust, then scrub with steel wool or a wire brush. After removing the rust, neutralize vinegar with a baking soda and water solution.

Tips for Larger Tools:
If your tools are too large to fit in a container, wrap them in a cloth soaked with vinegar and salt, then place them in a plastic bag. Check the tools periodically to see if the rust has softened. When rust is loose, then follow “After Soaking” steps.
 

Important Note: Vinegar is a mild acid, so it can dissolve and pit steel if left on for too long.
