The most common way a new tree or shrub dies around Monticello is not disease or planting depth. It is that nobody watered the root ball. The irrigation ran, the mulch looked damp, and the tight pot-shaped ball of roots under the plant was bone dry through a May with no rain. Established plants pull water from a wide area. New ones can only reach what is in the ball, and the ball has to be watered directly.
Why the sprinkler does not do it
A lawn sprinkler puts down a half inch or so over the whole surface. On a new plant, that half inch hits the mulch, wets the top inch, and mostly evaporates. The root ball is a dense block of potting mix that sheds water once it has dried, and it sits in soil that is a different texture, so water from the surrounding ground does not move into it easily. Meanwhile the plant is transpiring hard in the heat. Within a week of dry weather the ball is dry and the plant wilts, while the lawn around it is fine.
Drip emitters aimed at the ball work. A hose at the base works. A sprinkler does not.
The first-year schedule
These are the rates that work in Big Bend conditions for container-grown plants. Balled-and-burlapped trees need more time. Adjust for rain; a real inch of rain counts as a watering, a quarter inch does not.
Shrubs, one to three gallon
- Weeks 1 to 2: water the root ball every day, about a gallon per plant, slowly.
- Weeks 3 to 8: every other day, one to two gallons.
- Months 3 to 6: twice a week, two to three gallons.
- Through the first year: once a week in dry weather. After that, only in real drought.
Trees, seven gallon and up
- Weeks 1 to 3: daily, two to three gallons per inch of trunk diameter, applied slowly at the ball.
- Weeks 4 to 12: every two to three days, same amount.
- Months 4 to 12: weekly, and twice weekly in a dry spell.
- Year two: every two weeks in drought. Roots are into the native soil by now and the plant can start to look after itself.
Large trees take a year of establishment per inch of trunk diameter. A three-inch caliper oak needs attention for three years, not one.
How to apply it
Slowly. A gallon dumped from a bucket runs off the top of a dry root ball. A hose on a trickle for ten minutes soaks in. Options that work:
- A hose on a slow trickle at the base, moved plant to plant. Cheap and reliable; the limit is your patience.
- A slow-release watering bag around the trunk of a tree, filled once or twice a week. Excellent for trees in lawn.
- Drip emitters on a bed line, one or two per shrub aimed at the ball, run on their own zone so they can go long and slow. This is the right answer for a whole new bed.
- A five-gallon bucket with a small hole in the bottom set beside the trunk. Fill it and walk away.
Mulch and the basin
A ring of mulch two to three inches deep, pulled back a few inches from the trunk, slows evaporation and keeps the mower and trimmer away. A shallow soil basin around the edge of the ball on a slope holds the water where it needs to soak. Our mulch depth guide and the trimmer damage post cover the rest of the ring.
Signs you are getting it wrong
- Wilting in the afternoon that recovers overnight: the ball is drying between waterings. Water more often.
- Wilting that does not recover: the ball is dry through, or it is waterlogged and the roots are rotting. Push a finger into the ball to find out which.
- Yellowing lower leaves and a sour smell: too much water in heavy clay. Cut back and make sure the planting hole drains.
- Leaf scorch on the edges in summer: usually thirst, sometimes fertilizer burn from feeding a new plant. Do not fertilize new plantings the first season.
Timing the planting
Everything above is easier if the plant goes in when it is not fighting heat. Fall planting, October through early December, gives roots a whole cool season to grow before the first dry spring. Our post on when to plant in North Florida makes the case.
FAQ
Can I overwater a new plant?
Yes, on clay and in a hole that does not drain. On sand it is hard to. Check the ball with a finger before deciding.
Should I water at night?
Early morning is best. Evening watering is fine for the root ball but wet foliage overnight invites fungus on some shrubs.
Do native plants need this?
Yes, the first year. A native is adapted to the region once established, not while it is still in a root ball.
Do you handle planting and follow-up?
We install beds and plantings and can set up drip on the bed as part of the job. See our landscaping services.
If you've put in new plants and want them to make it through their first summer, reach out and we'll set up the watering properly. We handle landscape work across Monticello, east Tallahassee and the towns between.
