Spread Seed in the Spring and Fall as a Weed Preventative

Any bare or thin spots on your lawn are likely to fill with weeds or crabgrass.  Your best defense against this is having your lawn thick and full.  Although fall is the best time for major lawn renovations, spring seeding is important in an organic lawn system.  Unlike in a conventional chemical program, Nature Guard does not apply a pre-emergent herbicide in the spring to prevent any seed from germinating.  There are a couple of key points to consider when seeding in the spring.

  • Seed mix:  The goal is to pick a seed that will germinate and establish quickly to help shade the soil and prevent crabgrass and other weed seeds from germinating.  When spring seeding – use a mix that is mostly or all perennial ryegrass or annual ryegrass (annual ryegrass will die off, but you can reseed in the fall with your preferred perennial grass).
  • You will need to do some preparation to the site before you seed by heavily raking the area to remove any thatch and loosen the soil. Seed stitchers, garden weasels and other such tools are useful for this as well.
  • You can also lightly top dress with compost or good soil. Seed can be spread by hand or with a spreader.
  • The seed will need to be kept moist (but not saturated) to get germination. A light watering 2-3 times a day is ideal until the seed germinates.

Fall is the best time for large lawn renovations. All of the cool season grasses used in our area naturally seed in the fall. Weather conditions are ideal for germination of seed, cooler days and adequate rainfall. There is also very little completion from weeds in the fall. Fall seeding is often done in conjunction with core aeration.
