"TJB designed and installed a pondless waterfall where a small fishpond had previously been located. The design was challenging owing to the small area available to accommodate the feature. But Ted and his crew came up with a very pleasing design. The sound from the waterfall is very pleasant and the waterfall can be viewed and enjoyed from a variety of locations both within the house and out in the yard. I love this addition to my yard! The work was completed quickly and the price was reasonable. I recommend this company and would use them again."

"I could not be happier with my choice. Shawn was professional, friendly, and knowlegable from first contact. He was not the cheapest nor the most expensive estimate I received to complete the work. His quote included more than the cheaper and more expensive estimates I had received. Once hired he began immediately and removed the trees from the house in the first day. It took a little time to complete the job but his concern was the ruin of a lawn in pristine condition. He waited for the ground to dry before starting the portion of the work that required heavy equipment. The lot is also on a very steep downward angle . I feel that he completed the job in a timely manner considering that the weather continued to work against him. Upon finishing he left the property in excellent condition. He removed the 7 foot diameter root ball as well so one would never know the wreck it all had been . The only tell tale sign is where he graded, seeded, and fertilized the portion on the yard where the trees had fallen and gouged the ground."

Lawn Fertilization and Treatment questions, answered by experts

Bermuda grass may be drought-resistant, but it still needs to be watered once or twice a week. The suggested amount of water Bermuda grass needs varies from season to season. Bermuda grass needs about 1 inch of water a week in summer, fall, and winter; it needs up to ¾ inch in spring.

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.

Properly preparing the soil for planting grass seed may include applying fertilizer several weeks before spreading the seed if you plan to overseed the lawn. However, in most cases involving a brand-new lawn, spreading a starter fertilizer along with the grass seed will give it the best chance of taking root quickly and growing strong.

You should fertilize your lawn after it has grown at least two inches or after your second mow (usually in March or April). Applying fertilizer too early can feed your weeds and cause them to grow stronger, too. You should water your lawn two to three days before you apply fertilizer to ensure the soil absorbs it.

It’s not required, but it is helpful if your goal is to produce new growth. Any fertilization should occur after the lawn is aerated and before the compost is applied. If you also plan to spread seed, you’ll want to do so after the fertilizer is applied and once the ground is damp, but not wet.
