    Lawn Care & Irrigation

    When you understand your lawn's environmental needs and tailor your lawn care practices to suit local conditions, you get a healthy, environmentally-friendly lawn. Design your yard so it thrives on rainwater alone, without additional irrigation.

    • Tips to Get You Started

      Mulch your garden and landscape beds
      Mulch helps keep the soil moist and reduces erosion and weeds. Avoid piling mulch against plant stems and tree trunks to prevent rot.

      Water at the right time
      Watering in the early morning or late evening when temperatures and wind speeds are the lowest will reduce water loss through evaporation. Check with your local Water Management District office or Cooperative Extension Service office to find out how often to water. Tighter watering restrictions may be in order for different counties (ranging from one day per week to two days per week) and as restrictive as from 8:00 am to 6:00 pm for no watering.

      Set your timers
      To keep your yard healthy with just enough water, it is important to set your timer with a watering schedule that suits your area considering the amount of rainfall you usually get. For example, in Central Florida, a suggested watering schedule is two days a week (such as Monday and Thursday) with an irrigation run time that varies by month, as described in the table below.

      MonthWater Time (in minutes)
      January   12
      February 10
      March 17
      April 40
      May 64
      June 50
      July 49
      August 60
      September  48
      October  43
      November 32
      December 16


      By following a similar type of schedule in your area, you can save about 10 - 20 percent on your water bill. However, keep a close eye for signs of excessive wilting if rainfall is not typical. The amount of watering needed can vary by the types of plants you have in your yard. Planting native plants can also help conserve water in your landscape.

      Calibrate your irrigation system
      Be sure to calibrate your irrigation system to determine how long to run the system so that it delivers the amount of water recommended for your area. Irrigation systems can be very different and could be delivering too much, not enough, or just the right amount of water, depending on the type of irrigation system and the zone being watered.

      Position sprinklers properly
      Make sure the water lands on your plants and grass and not on paved areas. Lawns only need about ¾ inch of water in one watering session.

      Place empty tuna cans or measuring cups around the yard (all within range of the sprinkler, some close, some farther away). Turn on the sprinkler for 30 minutes. After 30 minutes, measure the amount of water collected in each can/cup. Check to see if there was even distribution of water in all the cans/cups. If the cans/cups collected ¾ inch of water, then you know you need to water for 30 minutes. If the cans/cups collected more or less than ¾ inch of water, then calculate approximately how long you need to water your landscape so that it receives ¾ inch of water in each watering session.

      Use micro-irrigation hoses
      These hoses can lie above ground or slightly buried and allow for water to seep through to a plant's roots.

      Make the most out of rainwater
      Turn downspouts from rain gutters towards areas with planting. Rainwater can also be collected and stored in a rain barrel for dry spells.

      Mow your grass to the right height
      The higher the grass, the more extensive the root system becomes. Grass with deeper roots is more drought-resistant. If the grass is mowed very short, it will put most of its energy into growing new leaf blades, and less energy into growing a root system (root system will be shallow). So don't mow your lawn too short.
