Tuff jobs is a proud family business owner that specializes in deck building, land clearing, landscaping, and pretty much your local jack-of-all-trades. I pride myself in delivering quality work...exactly what the client needs and asks for. My 5 star reviews and business name is just one example of that. I'm new to Angi, so most of my reviews are in a different place. If you want the link, just ask! Will you be the next person to give me 5 stars? Reach out and let's tackle that project together.

"Tuff Jobs worked with me to understand the repair I needed, the budget I had planned, and the timeline I had in mind. The work was excellent and Stryker was professional, responsive, cleaned up thoroughly, and even helped me understand the root cause of the damage I needed repaired. Will use Tuff Jobs again for projects big and small."

Lawn Fertilization and Treatment questions, answered by experts

Leaf removal, aeration, dethatching, mowing, pruning, and fertilizing are activities that prepare lawns for the next season.

Depending on the lawn treatments, the best times of the year to redo your lawn are between mid-August and mid-September for overseeding and renovation treatments. For areas such as the southern United States, lawn aeration works best during the fall, when the temperatures begin to drop. Otherwise, early spring is your next best bet because the grass is fresh and ready to absorb nutrients, and the temperature isn’t hot enough to fry the grass and the renovation materials.

At its core, soil pH is a measure of how many hydrogen ions are present in your soil. In highly acidic soil (low pH), plant growth is difficult due to reduced microbial availability in the dirt.

In highly alkaline soil, plants may struggle to grow due to iron deficiencies. In either case, a lack of balance deprives grass or plants of some key nutrients they need to grow.

A pH reading of 6 to 7.5 is ideal for most plants. Slight acidity is, generally speaking, less of an issue than slight alkalinity. Many plants can still thrive in slightly acidic soil.

Look for a broadleaf herbicide, one that has been formulated specifically for dandelions and is considered grass-safe.

Speeding up grass seed germination is possible, but it requires quite a bit of extra work and commitment. Keeping the soil moist is key, but here are a few other tried-and-true methods for growing your new grass as quickly as possible:

  • Mist grass up to eight times per day to keep the soil moist.

  • Purchase a moisture-retaining seed coating for your grass seeds.

  • Amend soil that is compacted or in the wrong pH range.

  • Choose the right grass seed for your area’s climate and soil conditions.

  • Avoid planting on windy days or during periods of extreme rain or drought.
