The most crucial factor for plant health and vigor is appropriate irrigation. Immediately after planting and until the plant becomes established, perennials, shrubs, and trees need water to thrive. When you water make sure you are watering the soil where the new rootball is located. Never water when the rootball is saturated.
How do you know when your plants are established? In our region it normally takes one year for each inch of trunk diameter. So a 2″ trunk diameter tree would take two years to be established.
Trees over 2″ Trunk Diameter
Apply one gallon of water for each inch of trunk diameter each time you water:
- Daily for one week per inch of trunk diameter.
- Every other day for one month per inch of trunk diameter.
- Weekly until plant is established.
Shrubs & Trees under 2″ Trunk Diameter
Apply one gallon of water each time you water:
- Daily for 2 weeks.
- Every other day for 2 months.
- Weekly for one year.
Water daily for 2 weeks, then gradually reduce until you are applying 1″ of water per week. Water needs vary based on the soil and the plant type, but generally water when the top 1″ of soil is dried out. Watering deeply but infrequently will encourage deeper roots.
Keep constantly moist in order for the seeds to germinate. Water the lawn by hand twice a day, once in the morning and once in the evening for 15 minutes each time. Do not let the water puddle; rather, use a light mist to allow for even saturation. Continue watering in this way until you see green shoots emerging from the soil.
Once the lawn has germinated, cut watering back to once a day for half an hour. A first cut should be done when the tip of the blades of grass barely start to flop over. It is best to cut all lawns at 3” or more. Once your lawn has been mowed 2-3 times, begin watering deeply and infrequently – about 1” once a week; less when there is rainfall.
Thoroughly soak so that water penetrates through the sod and into the soil. This means watering for at least an hour each day. Be sure that the entire area is thoroughly soaked. If you are using a sprinkler, check it to be sure it covers the area evenly.
