How Often To Water New Shrubs?
Water new shrubs every day for the first week, then 2 to 3 times a week for the first few months. Learn how long to keep it up and how much to give.
Water newly planted shrubs every day for the first week, then 2 to 3 times a week for the next 2 to 3 months. After that, a deep soak once a week through the first year is usually enough. Always check the root ball, because it dries out faster than the soil around it.
A starting point, not a rule. Check the soil before each watering and stretch the gap in cool, cloudy weather.

Most new shrubs that die in their first year die of thirst. They looked healthy at planting, then quietly dried out over a few hot weeks.
A shrub from the nursery arrives with its roots packed into a small ball of potting mix. That mix dries out much faster than garden soil, and the roots have not yet grown into the ground around it. Your job is to keep that root ball moist until the shrub can find water on its own.
New shrub watering schedule
| Time since planting | How often |
|---|---|
| Week 1 | Every day |
| Weeks 2 to 12 | 2 to 3 times a week |
| Rest of the first year | Once a week |
| Second year, dry spells | Every 1 to 2 weeks |
| Fall planting, after leaves drop | Only when the soil is dry |
Count rain, but do not trust a light shower. It often wets the mulch and never reaches the roots.
How to tell when a new shrub needs water
Push a finger or trowel 3 to 4 inches into the soil right at the edge of the original root ball. That is where the roots are. If it feels dry, water.
The surrounding soil can feel moist while the root ball is bone dry. Always test right next to the stems, not a foot away.
How to water new shrubs
- Water slowly at the base. Let a hose trickle for a few minutes, or fill the water ring twice.
- Give 2 to 3 gallons per shrub. Small shrubs need about 1 gallon. Large ones may need 5.
- Water in the morning. Less is lost to evaporation, and the leaves dry quickly.
- Mulch 2 to 3 inches deep. Keep mulch a few inches away from the stems.
Signs of overwatering and underwatering
Too much water
- Yellow leaves that drop early
- Soil that stays muddy for days
- Black, soft stems at the base
- A sour smell from the planting hole
Too little water
- Wilting in the morning
- Brown, crispy leaf edges
- Leaves dropping in summer
- Dry, pale needles on evergreens
How long to keep watering
Most shrubs need about one full growing season to root into the surrounding soil. Large shrubs can take two years. Keep up weekly deep watering through that time, especially in summer.
Evergreens such as boxwoods and hollies also lose water through their leaves in winter. Give them a deep drink in late fall before the ground freezes.
The same timing applies to young trees, as covered in our guide to watering new trees. Flowering shrubs like hydrangeas need even more water than most.
New Shrubs watering FAQ
How long should I water new shrubs?
Keep watering regularly through the first full growing season, and in dry spells through the second year for large shrubs.
Can you overwater new shrubs?
Yes. In clay soil especially, water can pool around roots. Check the soil before watering and let it dry slightly between drinks.
Should I water new shrubs in winter?
Only when the ground is not frozen and the weather is dry. Evergreens benefit from a deep watering in late fall.
