As temperatures begin to cool and leaves start falling across Connecticut, it’s tempting to put away the garden hose and call it a season. After all, plants are slowing down, summer heat is behind us, and winter is just around the corner.

But here’s something many gardeners overlook: your plants still need water in the fall, even when they don’t look like they’re actively growing!

In fact, keeping your landscape properly hydrated before winter can make a big difference in how healthy everything looks come spring.

Why Fall Watering Is So Important

While cooler temperatures mean plants generally need less water than they did during summer, their roots are still active as long as the soil hasn’t frozen.

During autumn, trees, shrubs, and perennials are preparing for winter. Having adequate moisture in the soil helps protect their roots from freezing temperatures and reduces stress during the colder months.

And just because we’ve had a few chilly mornings doesn’t mean the soil is getting enough moisture. Connecticut can experience surprisingly dry stretches in October and November, making supplemental watering especially important.

The tricky part? Damage from fall drought often doesn’t show up until spring. Browning foliage, delayed growth, and struggling plants can all be signs that your landscape went into winter too dry.

What Plants Need the Most Attention?

Not every plant needs the same amount of water, but a few deserve some extra attention before winter arrives.

• Newly Planted Trees & Shrubs: Anything planted this season is still establishing its root system. Consistent moisture is essential for helping these plants settle in before winter.

• Evergreens: Arborvitae, boxwoods, rhododendrons, and other evergreens continue losing moisture through their foliage during winter. Entering the season too dry can contribute to winter burn and browning.

• Hydrangeas & Perennials: Shallow-rooted plants can be especially vulnerable during dry conditions. Keeping their root zones hydrated helps reduce winter stress.

• Established Trees & Shrubs: Even mature plants can benefit from a deep watering when fall rainfall is scarce.

How Much Should You Water?

The good news is that fall watering doesn’t need to be complicated!

Rather than following a strict schedule, pay attention to the weather and soil conditions. If Connecticut has been receiving consistent rainfall, you may not need to water much at all.

An easy way to check? Dig down about 4–6 inches into the soil. If it feels dry, it’s probably time for a good soak. If it’s already moist, hold off.

When watering, focus on giving plants a slow, deep soaking rather than frequent, shallow watering. This allows moisture to reach the root zone where it’s needed most.

Whenever possible, water during the warmer part of the day, especially as nighttime temperatures begin dipping toward freezing.

And remember, more water isn’t always better! Saturated soil can cause just as many problems as overly dry soil.

When Can You Finally Put the Hose Away?

Here’s the general rule for Connecticut gardens: Continue watering as needed until the ground freezes.

A light frost doesn’t mean it’s time to stop! As long as the soil is workable and temperatures allow, your plants can still benefit from moisture.

So before you officially close up the garden for the season, give your trees, shrubs, and perennials a little attention. A few extra watering sessions this fall could mean healthier plants and fewer surprises next spring.
