Your Quick Guide to Fast Lawn Growth: Buying Quick Growing Grass Seed

Want a lush, green lawn fast? Quick growing grass seed is your answer. This guide helps you pick the best blend for your yard. Fast results mean less waiting time!

Key Features to Look For

When you buy quick growing seed, check these things first. These features promise faster results.

Speed of Germination

This is the most important part. Look for seeds that sprout in 5 to 10 days. Some super-fast mixes sprout even sooner. The package should clearly state the expected germination time.

Coverage Rate

Check how much area one bag covers. This stops you from buying too little or too much seed. Measure your lawn area before shopping.

Seed Coating

Many modern seeds come coated. This coating often contains nutrients or a protective layer. This layer helps keep the seed moist and guards against birds. Coated seeds usually grow faster and stronger.

Important Materials: What’s Inside Matters

The types of grass included determine how fast your lawn grows and how it looks later. Quick growing seeds often mix different types of grass.

Annual Ryegrass

Annual ryegrass is the speed king. It germinates incredibly fast, often within a week. It is great for quick fixes or temporary cover. Remember, it usually dies off in the first hard frost.

Perennial Ryegrass

This is a top choice for fast results that last. Perennial ryegrass grows quickly and stays green year after year. It mixes well with other grass types.

Kentucky Bluegrass

While a bit slower than ryegrass, Bluegrass creates a thick, beautiful lawn. It often mixes with faster seeds to ensure quick initial coverage while the Bluegrass establishes itself long-term.

Factors That Improve or Reduce Quality

Not all quick growing seeds perform the same. Quality depends on what you avoid and what you choose.

Seed Purity

High-quality seed bags have very few weed seeds or filler materials. Always choose brands that guarantee high purity percentages (usually 95% or higher). Low purity means more weeds and less actual grass growing.

Grass Seed Viability

Viability means how likely the seed is to sprout. Old seed loses its ability to grow. Buy seed that was packaged recently. Do not buy seed that has been sitting in hot sunlight on a store shelf for too long.

Soil Preparation (User Action)

The best seed fails if the soil is bad. You must prepare the area first. Loosen the top layer of soil. Add compost if the soil is hard. Good, loose soil allows the tiny roots to push through easily, which speeds up growth.

User Experience and Use Cases

Why do people choose fast-growing seed? The uses are varied, but speed is always the goal.

Patch Repair

Did your dog dig a hole? Did the winter kill a patch of lawn? Quick growing seed fixes these bare spots rapidly. You see results before the neighborhood notices the damage.

Erosion Control

If you have a slope or newly graded area, fast grass stops soil from washing away during heavy rain. The quick roots hold the dirt in place right away.

Overseeding

If your existing lawn looks thin, you can spread quick seed over the top (overseeding). This fills in the gaps quickly, making your lawn look fuller faster than waiting for the old grass to thicken up.


10 Frequently Asked Questions (FAQ) About Quick Growing Grass Seed

Q: How fast is “quick growing”?

A: Generally, quick growing seeds sprout in 7 to 14 days. Some specialty mixes promise visible growth in as little as 5 days.

Q: Will quick growing grass last forever?

A: Some types, like Annual Ryegrass, do not last through the winter. Blends containing Perennial Ryegrass and Bluegrass create lawns that last multiple years.

Q: Can I plant quick seed when it is cold?

A: No. Most grass seeds need warm soil to sprout. Check the specific requirements, but usually, soil temperatures between 55°F and 75°F are best.

Q: Do I need to water the seed every day?

A: Yes, you must keep the top inch of soil constantly moist until the grass sprouts. Once it grows tall, you can water less often but more deeply.

Q: Does cheap seed work just as well?

A: Cheap seed often has low purity and old seeds. You will likely get fewer sprouts and more weeds. Quality costs a bit more but saves time later.

Q: What is the best way to spread the seed?

A: For small areas, spread the seed by hand, tossing it evenly. For larger lawns, use a spreader tool to ensure even coverage.

Q: Should I use fertilizer with quick seed?

A: Yes. A starter fertilizer applied right after planting gives the tiny seedlings the energy boost they need to grow fast.

Q: What if I see birds eating my seed?

A: Birds love fresh grass seed. If you do not have coated seed, cover the seeded area lightly with straw or netting until you see the first sprouts emerge.

Q: Can I mow the lawn once it grows fast?

A: Wait until the grass is about 3 to 4 inches tall before the first mow. Keep your mower blade high for the first cut.

Q: Are quick growing seeds good for shady areas?

A: Not always. You need to check the bag specifically for shade tolerance. Most fast-growing mixes prefer full sun.
