Lawn Irrigation questions, answered by experts

The fastest growing grass seeds are Bermuda grass, which is a warm-season grass and ryegrass, which is a cool-season grass. Both of these grass types tend to germinate in five to 10 days. Other fast-growing varieties include perennial Ryegrass and fescues, all of which have unique characteristics and growing requirements.

Yes, Bahia grass spreads on its own thanks to its short stolon system. However, it might not seem like your Bahia grass spreads well due to its slow growth. Bahia grass takes around 3 to 4 weeks to germinate and an additional two weeks to grow thicker. 

During this time, fast-growing, competitive weeds may pop up, so weed your lawn to give your Bahia grass a chance to grow. This grass can take up to two years to become established. Once established, Bahia grass typically does well in suitable climates.

You should put pre-emergent herbicide and fertilizer on your lawn in the spring. Pre-emergent herbicide keeps weeds from taking root. Fertilizer helps your grass to grow lush and dense and blocks future weeds from growing. You can also add amendments, such as sulfur and lime, to enhance your soil quality. 

There are a few ways to fix your lawn on a budget, including:

  • Identify the lawn care problem and learn how to seed, fertilize, and aerate your lawn. 

  • Reseed old, damaged lawn with new grass that fares better in your environment. 

  • Remove grass from your yard so you no longer need to worry about lawn care costs.

While hydroseeding is designed for bare soil, it is possible to apply it over an existing lawn with certain adjustments. For the new seed to be successful, it needs good seed-to-soil contact to germinate and take root. Without proper preparation, most of the new seed will fail to establish and will die. To hydroseed over existing grass, first mow the lawn as low as possible, then loosen and clear any exposed soil. It is also recommended to use a finer mulch mixture in the hydroseed spray, which helps the seeds penetrate the existing turf and reach the soil without suffocating the established grass.
