Any time Bermuda start to grow in your St. Augustine grass, this is a sign of poor fertilization practices. Bermuda always takes over when the St. Augustine becomes weak.

  1. Which Grass is Better, Bermuda or St Augustine?

St. Augustine handles shade better while Bermuda grass thrives in constant sun and does not grow well in the shade.  Bermuda grass has a lot of strengths. It is well known for its drought tolerance, heat tolerance, deep rooting potential, durability, good recuperative potential, salinity tolerance, rapid establishment rate, and low disease potential. This is the most favourite grass by many professional gardeners.

  1. What are the Benefits of  Lawn Fertilization? Is it necessary as Lawn Care?

The “why” is very important. The benefits come from the need itself. A lawn requires continuous nutrients. You job as a lawn owner to make sure that it is protected.

  • The protection of lawns from nutrient-deficiency.

Over time, many lawns will leech nutrients out of their soil. Most nutrients for your grass are water-soluble. Over time, whether through rain or irrigation, the water will carry these nutrients out of your lawn. How can You know if Your lawn is nutrient deficient? You will need to perform a soil test. It will tell You about the soil composition in detail, and then You can safely choose the right fertilizer. Then You can replenish the lost nutrients.

  • Lawn survival and health are dependent on 3 factors equally: sun, water, and nutrients.

This item emphasizes the 1st one. But it helps You to understand that fertilizer is not a “nice to have” but a must-have item in responsible gardener’s schedule. The same as You feed pets, Your lawn requires food too.

  • It encourages your grass to grow.

Let’s be honest. We are not a patient society. We all want our lawns to look green and beautiful today not tomorrow. Fertilizer comes to play here too. If You know when, how much and where to use, you can make your grass grow at a super-fast pace.

  • Organic fertilization helps your lawn absorb more water and nutrients.

You might be surprised to read this, but if you don’t fertilize your lawn – you might be struggling with watering it. Lawn fertilization is required for healthy soil. Better soil structure means better infiltration and water-holding capacity. That’s why so many residents across Houston, Texas, use lawn services to fertilize their lawns.

  • Trees, bushes, and other plants in Your yard will benefit from the fertilizer.

Sometimes if the soil is sandy, trees and brushes might require further fertilization. But the lawn fertilizer can help them survive a lot. 

  1. Should I Fertilize or Seed First?

However, health and safety is our priority. To be absolutely sure that the grass is devoid of residual fertilizer, wait 48 hours to pass passed after the fertilizer application.

“How often” questions manage your schedule and expectation about adequate lawn fertilization. 

  1. How Often Should you Fertilize Grass?

  1. Can I Fertilize my Lawn Every 2 Weeks?

It depends on the fertilizer that You use: slow-release or fast -release. You can reapply slow-release fertilizers every six to eight weeks, while a fast-release fertilizer can be reapplied every four weeks.

  1. Can You Over-fertilize your Lawn?

If You  see brown, yellow, or streaked grass after You fertilized Your lawn, then You most likely spilled too much fertilizer there. It happens, and it hurts Your lawn.

The accumulation of salts weakens both lawn health and soil structure. Excessive nutrients change the PH Balance of your soil.

Here are the main reasons why gardeners or lawn service providers over-fertilize the lawn:

The size of an area is miscalculated. It is crucial to get your figures right when fertilizing based on an area’s size. Always start with the outer dimensions. And even then, You can make mistakes. So remember to deduct non-lawn areas. They are your home, outbuildings, and driveways.

Guessing fertilizer quantities.  You must have a set of measuring cups that You devote to garden fertilizers. Bypassing them increases the risk of burn, especially when directly fertilizing individual plants.

Leaving the spreader hopper open when filling, stopping, or turning. Unless you close the hopper when you load, stop or set your spreader, fertilizer keeps coming out. Every pile of excess fertilizer is an opportunity for fertilizer burn.
