How to Water Your Plants in Baltimore: A Seasonal Guide

Watering sounds like the simplest part of plant care. Give your plants water, and they grow.

In reality, figuring out when and how much to water is one of the trickiest parts of keeping plants healthy — especially in Baltimore, where a cool, rainy spring can quickly turn into weeks of hot summer weather.

The most important thing to remember? Your plants don't need a watering schedule. They need you to pay attention to what their soil is telling you.

Here’s how we approach watering at Nest & Bloom.

Check the Soil, Not the Calendar

It's tempting to decide that Sunday is plant-watering day and water everything in the house at once.

The problem is that your plants probably don't all need water at the same time.

A plant beside a sunny south-facing window may dry out much faster than one sitting across the room. A small terracotta pot can dry considerably faster than a large glazed planter. And a plant's water needs will change throughout the year.

Instead, get into the habit of checking the soil.

For many houseplants, you can push your finger about an inch or two into the soil. If it still feels moist, wait. If it's dry, it's probably time to water.

Over time, you'll start recognizing each plant's rhythm without thinking much about it.

Water Thoroughly When You Do Water

One of the most common watering mistakes is giving plants frequent little sips.

Instead, most potted plants prefer a thorough watering that reaches the entire root system.

Water slowly until you see water draining from the bottom of the pot. Let it finish draining, and empty any excess water that collects in the saucer.

Then give the soil time to dry to the appropriate level before watering again.

Good drainage is an important part of this equation. A beautiful planter isn't doing your plant any favors if its roots are constantly sitting in water.

Baltimore Summers Change Everything

Once summer arrives in Baltimore, outdoor containers need a lot more attention.

Plants growing in pots have a limited amount of soil available to hold moisture. Add full sun, temperatures in the 80s and 90s, warm patios and a few breezy days, and that soil can dry surprisingly quickly.

During the hottest parts of summer, check outdoor containers every day.

That doesn't necessarily mean water every container every day. Check them.

A large planter in partial shade may still have plenty of moisture. A small terracotta pot sitting on a sunny Baltimore patio may already be bone dry.

Your garden's individual conditions matter more than any watering rule.

Pay Attention to Where Your Containers Live

Two identical planters can have completely different watering needs depending on where they're placed.

Containers against brick walls or sitting on stone and concrete can experience significantly more heat than plants surrounded by garden beds.

Full-sun containers will generally dry faster than shaded ones. Windy balconies and rooftops can dry pots especially quickly.

Even rain can be misleading.

Containers tucked beneath an overhang may receive very little water during a summer storm. And once a container fills with foliage, the leaves themselves can sometimes prevent rain from reaching much of the soil.

After a storm, don't assume everything has been watered. Check.

Morning Is a Great Time to Water

For outdoor plants, we generally prefer watering in the morning.

The temperatures are cooler, there's less evaporation and your plants have moisture available before the heat of the afternoon.

Try to direct the water toward the soil and root zone rather than routinely soaking the foliage.

But don't get too hung up on perfect timing.

If you walk outside at 4 p.m. and discover a very dry container struggling in the heat, water it. A thirsty plant doesn't need to wait until tomorrow morning because that's technically the better watering time.

Different Plants Want Different Things

This is where watering gets interesting.

Lavender, rosemary and thyme generally prefer conditions on the drier side.

Basil and many other leafy plants prefer more consistent moisture.

Tropical houseplants may have completely different needs from your succulents.

This is why we love grouping plants with similar needs together, especially in mixed containers and herb gardens. It makes caring for them much easier.

Don't Assume Wilting Means “Water Me”

Here's an important one.

A wilting plant can absolutely be thirsty.

But a plant can also wilt because its roots have been sitting in soil that's too wet.

Before automatically reaching for the hose or watering can, feel the soil.

If it's dry, give your plant a drink.

If it's already wet, more water isn't the answer.

Your Plants Will Teach You

Good plant care is less about memorizing rules and more about learning to notice things.

You'll start recognizing which containers dry first after a hot day. You'll know which houseplant can go quite a while without you and which one starts looking dramatic the minute its soil gets a little dry.

You'll notice how things change from May to July and again when cooler September nights arrive.

And that's really the secret to watering well: pay attention to the plant in front of you.
