      For other size areas, use the following formula to calculate how many plants you will need:  (Area in sq. feet) x (Spacing Multiplier) = Number of plants needed

    • What size properties do you work with?

      We have conceived and installed designs from small front walkways and backyard gardens to comprehensive pool installations and outdoor rooms.  We

      generally have a project minimum of $2000.

    • Are you certified and accredited?

      Yes.  Urban Gardens inc. Landscaping and our employees hold the following industry certifications:

      • Maryland Home Improvement Contractor #51725
      • Certified Professional Horticulturalists
      • MD Certified Pesticide Applicators
      • NCMA, CSRWI Certified Installers
      • ICPI Level 1 Certified Installers
      • MDE Green Card Certified for Erosion Control
      • ab-seal-horizontal-large
    • How long will my project take?

      Once we begin a project, do our best to keep our team on site until it’s completed (we try to avoid a “stop and start” approach if at all possible.) Landscape and hardscape  schedules are often dependent on the cooperation of the weather, ground conditions, material availability.  On an average, the time from the initial consultation to final completion of the project is approximately two to three months for average sized projects.


    • How much should I budget for new landscaping?

      One of the most difficult aspects of any home improvement project is knowing how much to spend on the project.  Because attractive landscaping will increase your home’s value, and dramatically enhance your use and enjoyment of your property, some sources recommend investing 10% of your home’s present value on landscaping.  The fact is, a good landscape designer can help you achieve significant improvements on virtually any size budget.  The important thing is to decide ahead of time what your budget is, and discuss this with your designer so that they can design within that amount.

      Projects vary in cost based upon the complexity of the plan and the materials needed to bring the plan to life.  Our initial consultation and site assessment is free. We’ll visit your home, listen to your goals and ideas, and discuss possibilities for making the most of your property.  With your approval, a designer will then create a design for your project.  This plan will include full-color design of recommended features, and if appropriate, plant selections.  We will also provide detailed estimates for bringing the plan to completion. These professional design services are provided for a fee.   Learn more about our design services here

    • How should I water my new landscape?

      Newly installed plants need extra care and watering attention after being planted. If plants are allowed to wilt due to drying out, irreparable damage may occur to plant tissue.  Plants require extra care and attention during drought periods.  Even plants which may have been planted for several years may require extra watering during drought periods due to competition from surrounding trees and more mature plantings or because the root system hasn’t developed fully enough to support the plant.

      Check the soil before you water because over-watering can be just as detrimental as under-watering. Dig a small hole into the soil to at least 3 or 4 inches and feel the soil. If the soil feels moist to your touch then you don’t need to water. If there is visible water or water quickly seeps into the hole, defer watering for a few days. Although we think of watering during the late spring through the summer, fall watering is crucial to winter survival of newly planted plants. Therefore, continue monitoring watering until freezing temperatures occur regularly.  For large trees and shrubs turn on the hose to a slow trickle and let the water slowly soak into the soil around each plant.   Alternatively, a soaker type hose can be snaked through the plant bed. As a general rule of thumb, plants that grow in our climate like to have a minimum of 1 inch of water per week, preferably in several doses versus a big downpour.

      Minimum watering requirements:

      •  Deciduous trees, 2-3.5” caliper – 20 gallons per plant
      • Evergreen trees, 6-10’ height – 15 gallons per plant
      •  Shrubs, 18-24” height or spread – 2.5 gallons per plant
      • Ground cover, 2.25” peat pot – 50 gallons per 100 sq. ft.
      • Perennials, Grasses, Vines, 1 gallon size – 2 gallons per plant
      • Sodded areas must be kept moist during the first three months after completion to  maintain adequate soil moisture to a depth of a minimum of 6 inches. Sod may not recover if allowed to dry out before it has fully rooted. Don’t mow sod for the first two to three weeks after installation.

      Water Right for the Weather:

      • Cool, dry weather: water every 2-5 days, being sure to check soil moisture before watering.
      • Cool, wet weather: water every 7-14 days. Plant roots can rot if they’re sitting in water for long periods of time, causing decline and death of the plant.
      • Hot, dry weather: moisture should be checked daily. Frequent, daily watering, especially of smaller plants, may be required.
      • Rainy weather:   Check the soil a few days after a rain and water only if needed. Summer rain from a short cloudburst may run off quickly and not adequately soak the soil. Even a good rain in the summer might not be adequate if we’ve had a long period of drought.
      • Maturity of planting: In years two and three after planting, plants should still be watered to insure an average of 1 inch of rainfall or irrigation per week.  During a    prolonged drought, shallow rooted plants like azaleas, as well as plants planted in a wooded environment, will require some supplemental watering even after they are  well established due to tree root competition.
