Why do we aerate and compost lawns before overseeding?

Mow the lawn lower than 2 inches

  • Mowing short before overseeding prevents weeds and established grass from competing with new seedlings.
  • It also allows sunlight to reach the soil for the much needed warmth for germination.
  • Mowing also prevents grass seed wastage (seeds may lodge in the tall grass).

When is the best time to reseed your lawn?

Reseeding during this time is ideal because:

  • The soil will be warm enough to support seed germination
  • Weeds won’t be growing as rampant, so your new seeds won’t have to compete

How late can you oversee?

How Late In The Fall Can You Overseed? – You can overseed as late as temperatures stay high enough to support germination. I have sprouted cool season grass seed in soil temperatures as low at 45 degrees which can be found in many norther lawns well into late October. The later into the season it gets the fewer sprouts you’ll get and the thinner the grass will be going into winter but if you experience mild winters this may be better than dormant seeding or Spring seeding.

What grasses need overseeding?

What Grass Types Benefit From Or Need Overseeding? – Of all the primary turf grass varieties the rhizomatic and/or stoloniferous grass types benefit the least from overseeding because they spread horizontally into weak or thin spots in a lawn. The bunch type grasses like Perennial Rye, Turf Type Tall Fescue, and most of the Fine Fescues can thin out over time due to damage or injury. In some cases slow to spread grass types like Kentucky Bluegrass, Centipede, or Zoysia can benefit from overseeding at the end of Spring to speed up the thickening of the turf but this is not goin to be the case for all owners of these turf grass varieties.

How to make grass seed germinate faster?

To improve the speed of germination at this time of year you’ll want to sow your seed onto a deeply watered surface and then cover with pre-moistened peat moss or coconut coir, products that are very good at retaining moisture. Lastly, covering the entire area with crop cover will limit evaporative moisture loss due to wind and result in stable moisture levels in your seed. When seeds stay evenly moist and undisturbed by foot traffic form people or animals they will germinate quicker.

What grass seed grows the fastest?

What Grass Seed Grows The Quickest From Seed? – If you are seeding a new lawn or overseeding an existing lawn and short on time then planting Perennial Rye will give you the fastest grass sprouts of all grass types. In ideal situations it’s not impossible to see baby grass in as little as three days. For warm season climates Bermuda grass can germinate in just under a week and establish itself in another 10-20 days depending on soil temperatures.

Do you overseed or fertilize first?

Do You Overseed Or Fertilize First? – For fast germinating grass varieties like Tall or Fine Fescues and Perennial Rye it’s best to overseed the lawn and fertilize on the same day. This is because you want to put grass seed down and have the fertilizer become plant available in the soil at the same time. For slow to germinate grass varieties such as KBG, and most warm season varieties it can be beneficial to overseed and then wait a few extra days before applying starter fertilizer. It’s never a good idea to fertilize ahead of overseeding because the fertilizer will simply push new growth from existing grass and a lot of the fertilizer will either be used up (or lost) by the time germination roots finally reach into the soil from your seed.

Do you have to oversee your lawn every year?

Do You Have To Overseed Every Year? – The vast majority of people do not need to overseed their lawns every year. Only a select few grass types really need to be overseeded annually. Most fescues and annual rye grasses benefit from annual overseeding and damaged Kentucky bluegrasses can benefit because they don’t spread into weak spots fast enough to recover on their own. Most warm season grass types are rarely overseeded. Exceptions to this rule might be Zoysia and Centipede which are both slow growers however thin spots of these grass types can usually be repaired through better cultural maintenance and fertilization.

Do you have to rake in grass seed?

Do You Have To Rake In Grass Seed? – You should always rake in grass seed if you haven’t taken the time to dethatch your existing lawn prior to spreading seed. The reason is that raking helps improve seed-to-soil contact which is necessary for seed germination. Dethaching is a more aggressive form of raking and when done prior to seeding will create grooves in the existing lawn, thatch, and soil that grass seed can settle into. Dethatching is best but if you can can’t run an electric dethatcher over your lawn space raking in the grass seed is your next best alternative.
