Importance of Watering by Plant Size

May 6, 2025

So you recently had new shrubbery and trees planted to enhance the landscaping of your outdoor space. As these new additions establish themselves, proper watering is crucial for their growth and long-term health. This guide will help you understand the watering requirements based on the size of your plants, including 1-gallon, 3-gallon, and larger ball-and-burlap trees.

Importance of Watering

Adequate watering is vital in the early stages after planting. It supports root establishment, helps the plants adjust to their new environment, and promotes overall vigor. However, it’s important to water correctly—too little can stunt growth, while too much can cause root issues.

Watering Requirements by Plant Size

1-Gallon Shrubs

Watering Needs: These smaller plants generally require about 1 quart (32 ounces) of water every 2-3 days during the first few weeks after planting.
Transition: After the first month, you can reduce watering to once a week, giving them about 1 quart each time, ensuring the soil remains consistently moist but not saturated.

3-Gallon Shrubs

Watering Needs: Larger than their 1-gallon counterparts, 3-gallon shrubs typically need around 1-2 gallons of water initially. Water every 2-3 days for the first two weeks.
Transition: After establishing, reduce watering frequency to once a week, giving around 1-2 gallons each time. Monitor the soil moisture to ensure optimal conditions.

Large Ball-and-Burlap Trees

Watering Needs: Larger trees require significantly more water for successful establishment, typically about 5-10 gallons immediately after planting. It’s crucial to ensure that the entire root ball is well-soaked. Consider 10 gallons of water per caliper inch (measured 6 inches above the soil line) per week. For example, a 2-inch caliper tree might need 10-15 gallons per week.
Transition: For the first month, water 2-3 times per week, delivering 5-10 gallons each time. After the initial month, you can reduce to once a week, applying the same amount or adjusting based on rainfall and temperature.

General Watering Tips

Soil Check: Regularly check the moisture of the soil by digging about 2 inches deep near the base of the shrubs and trees. If it feels dry at that level, it’s time to water.
Watering Methods: Use the shower setting on your nozzle to deliver water directly at the base of the plants.
Mulching: Applying a layer of mulch around your plants can help retain moisture, regulate soil temperature, and suppress weeds.

Additional Considerations

Water early in the day to reduce evaporation and help the plants absorb moisture effectively.
If the weather is hot and dry you will need to resort to the original watering instructions until the weather passes. The first season from June through September are very stressful times for plants. Pay close attention.
Watch for signs of water stress, such as drooping leaves or wilting, which may indicate the need for more water.
Pay attention to the weather; if it rains or we experience extremely hot weather, you may need to adjust your watering schedule accordingly.
Once they make it to their first Winter they are on their own.
For the remainder of their life, it is always good to keep an eye on them during the hot summer months. They would appreciate any help you can give them.

Conclusion

By understanding the specific watering needs for your newly planted shrubbery and trees, you can better support their establishment and growth. With ongoing care and attention, these plants will thrive and enhance your landscape for years to come.

Happy gardening!
