Watering Guidelines

COUNTRY ARBORS NURSERY WATERING GUIDELINES

Proper watering is the single most critical factor in establishing healthy transplanted trees, shrubs, and perennials. Both overwatering and underwatering are common causes of plant stress and failure.

1. How to Apply Water

  • Use a garden hose with a slow trickle, a soaker hose, or drip irrigation system.

·         Sprinklers or turf watering systems are not recommended for new plants. They do not provide proper watering for root establishment.

  • Water Bags can be used, but surface watering is preferred.
  • Apply water slowly to ensure deep soil penetration and minimize runoff.

2. Where to Apply Water

  • Water the soil surface around the plant, not directly on the trunk. Keep water a few inches away from the trunk to prevent rot.
  • Avoid deep wand irrigation; surface watering encourages shallow root establishment, which is critical for newly planted trees.

3. How Often to Water

  • Newly planted trees, shrubs, and perennials are still establishing roots; check soil moisture regularly.
  • Your new plants need roughly 1–3 inches of water per week — but what does that actually mean? Think of it this way: a one-gallon jug of water spread over one square foot is about 1.5 inches. For most trees and shrubs, you are watering the root ball area, not your entire yard. The exact amount depends on three things: (1) Soil type — clay soil holds water much longer, so it rarely needs more than 1 inch per week. Sandy soil drains quickly and may need up to 3 inches. If you are unsure what soil you have, grab a handful when moist — clay soil holds its shape like putty, while sandy soil falls apart. (2) Plant size — a small container shrub needs far less water than a large balled-and-burlapped tree. (3) Weather — hot, dry, or windy conditions dry out soil faster and increase watering needs, while cooler or cloudy weeks may require less. A simple way to check: push your finger or a screwdriver 2–3 inches into the soil near the root ball. If it feels dry, it is time to water. If it feels moist, wait another day or two and check again.
  • Divide the weekly water amount into multiple applications for best absorption.
  • Rainfall over 3 inches per week may reduce supplemental watering needs.

·         Deciduous trees: Continue watering newly planted deciduous trees until the first hard freeze, when the ground begins to freeze and the tree enters full dormancy. As temperatures cool in fall, gradually taper back the frequency of watering while still ensuring the root ball receives adequate moisture. Adequate fall watering helps prevent root dehydration and supports healthy establishment before winter.

·         Evergreen trees and shrubs: Evergreen plants continue to lose moisture through their needles during winter. As fall temperatures drop, slowly reduce regular watering but continue to monitor soil moisture. If conditions are dry and the ground is not frozen, provide occasional deep watering to prevent winter desiccation and stress.

  • Supplemental watering is recommended during drought or the first 2–3 years post-planting until plants are fully established.

4. How Much Water to Apply

  • Water slowly and evenly.
  • Flooding is only recommended on the installation day to settle soil and remove air pockets.
  • Typical watering durations:
    • Container-grown plants: 10–30 minutes depending on size and soil type
    • Balled and burlap plants: 45–90 minutes depending on size and soil type

5. Special Considerations

  • Clay soils: Rarely need more than 1 inch per week; monitor to avoid saturation.
  • Sandy soils: May require up to 3 inches per week due to rapid drainage.
  • Plants near pavement or heat-retaining surfaces may lose water 20–30% faster.
  • Soil moisture should be monitored carefully during hot spells or drought conditions.
  • Mulching helps retain moisture and moderates soil temperature.

6. Signs of Overwatering or Underwatering

·         Overwatering: Leaves may turn yellow, appear soft, and begin to wilt even though the soil is wet. Newly planted plants may also drop leaves prematurely. The soil around the root ball may stay constantly soggy, which can reduce oxygen to the roots and lead to root stress or rot. Plants may look weak or fail to establish properly.

·         Underwatering: Leaves may turn brown and dry starting at the edges and moving inward. The plant may appear wilted, droopy, or stressed, especially during warm or windy conditions. The soil around the root ball will feel dry, and newly planted items may struggle to establish roots. Continued dryness can cause leaf drop, slowed growth, or dieback on branches.

7. Timing for Watering

·         Early morning watering is best because cooler temperatures allow water to soak into the soil before it evaporates. This helps ensure the root zone receives adequate moisture while allowing plants to begin the day fully hydrated before the afternoon heat. Watering in the morning also reduces disease risk, as any moisture on leaves or the soil surface has time to dry during the day, lowering the chances of fungal problems.

  • If morning watering is not possible, early evening (after 6:00 PM) is the next best option. Water should be directed at the soil around the root zone rather than the foliage. However, evening watering can leave plants and surrounding soil wet overnight, which may slightly increase the risk of fungal disease.
  • Midday watering (11:00 AM–4:00 PM) should be avoided whenever possible. During this time, higher temperatures and direct sunlight cause much of the water to evaporate quickly before it can soak into the soil, and plants may still experience stress due to the peak heat of the day.

 

2026 POST-PLANTING CARE INFORMATION

1. Pruning and Trimming

  • Only remove damaged or broken branches within the first year of planting.
  • Lower branches should remain to manufacture food and shade the trunk.
  • Shaping or corrective pruning should occur after plants are established, typically 2+ growing seasons post-planting.

2. Staking

  • Stake only if necessary (single-stem deciduous trees or windy locations).
  • Stakes should allow slight tree movement to encourage trunk and root development.
  • Stakes must be removed after approximately one year to prevent girdling.

3. Trunk Protection

  • Tree wrapping is generally not necessary and is not recommended for most newly planted trees.
  • If trunk protection is needed, use only breathable tree wrap materials that allow air circulation and help prevent moisture buildup against the bark.
  • Exceptions: Young trees with thin or smooth bark (such as maple, linden, or fruit trees) may benefit from wrapping to help reduce the risk of winter sunscald or frost cracking.
  • Tree guards may also be used to protect trunks from damage caused by lawn equipment or animals. Guards should allow adequate airflow around the trunk to prevent trapped moisture and potential bark issues.

4. Mulching

  • Apply 2–3 inches of bark mulch around the root zone.
  • Keep mulch 1–2 inches from the trunk to prevent rot.
  • Do not use landscape fabric or black plastic under mulch; it can restrict water and air.
  • Bark mulch improves moisture retention, root insulation, weed suppression, and plant growth during establishment.
  • Avoid using rock or stone mulch around newly planted material. Rock absorbs and holds heat, which can stress young roots and dry out soil more quickly.

5. Fertilization

  • Fertilization is generally not recommended at the time of planting.
  • If soil quality is poor, organic matter such as compost may be incorporated into surrounding soil.
  • In most cases, no fertilizer is needed during the first year if the tree was planted in reasonably healthy soil.
  • Fertilize in early spring of the following year, once the tree has begun to establish.
  • After establishment, if a tree shows poor growth, pale foliage, or nutrient deficiency symptoms, a light application may be appropriate.
  • We recommend a slow-release, balanced fertilizer.
