Weeding and Mulching

Lets imagine two yards, yard A and yard B

Each yard has a nice lawn of turf, freshly installed by a developers landscape copany.

The garden space is barren earth, dirt rock and clay, left blank for the homeowner to figure out the way they want things to go.

Lets say both homeowners A and B, in March, plant the exact same garden bed filled with topsoil and some perennial plants in each.

Homeowner A takes the extra step of laying down 2 inches of mulch over the garden bed because his brother in lawn knows something about gardening.

Lets say both homeowners then go on an extended vacation for 4 months and leave their gardens in the care of another neighbor-Bob, who they’ve told to just water the garden beds for them.

In September both homeowners return home to weeds in the garden.  A and B get to work weeding the garden bed, to bring it back. Not surprisingly , homeowner A finishes his weeding in one hour while his neighbor could be out there pulling weeds from the garden for days. So why is this?

Why are there weeds in my garden at all?

In our industry we use the term seed bank to estimate, determine or deduce why weeds grow in a garden where they were just eliminated year prior.

Weeds drop seeds every year. So if you weed your garden after the seeds have dropped, you’ll be enjoying the same weeding job next year. Year after year in doing this your garden builds up a bank of viable weed seeds which will keep germinating in years after you have been weeding in a garden. For this reason alone, weeding out your garden before seeds emerge is essential.

Seeds also drift along on the wind, barriers such as cedar hedge rows, fences, and geographically isolated yards help to minimize the migration of airborne seeds like dandelions, but won’t eliminate them completely. These weed plants, as the flowers emerge to identify their location, should be weeded out to stop the accumulation of banked weed seeds.

The roots of some plants also serve as a fresh starting point for another plant when the above portion of the plant and a portion of the root has been removed. Thistle, dandelion and quack grass are common persisting weeds in the garden and lawn. These weeds are difficult to fully remove without diligent followup work.

Garden Mulch

Mulch, on a garden is much like the blanket on our bed: keeps something unwanted out and something wanted, in. In the gardens case, mulch:

  • weakens weed seed growth, making often difficult to pull root masses easy weeding
  • It reduces your gardens current seed bank germination viability through directly burying the seeds below a depth they need to germinate.
  • Preserves nutrients in the soil reducing erosion from irrigation and during rainy seasons.
  • Allows better water penetration into the ground by slowing the diversion of water and topsoils out of the garden, erosion (this is particularly important in terraced and sloped garden beds)
  • Allows the growth of the soil microbiome (fungus),
  • Regulates root temperature and the rate at which water evaporates out of the ground.
