September Plant Care in Maryland: What to Water, What to Cut Back & What to Leave Alone
September is one of those funny months in a Maryland garden. Fall is starting to creep in, the days are getting shorter, and mornings may feel cooler, but our plants aren't necessarily ready to call it a season.
In fact, September can still bring plenty of warm, dry days, and many plants need consistent care well into fall. Before you put away the hose and start cutting everything back, here are a few things to keep in mind this month.
Don't Stop Watering Just Yet
One of the easiest mistakes to make in September is assuming cooler weather means plants no longer need much water.
Pay attention to the soil rather than the calendar. If we haven't had consistent rain, gardens can still dry out surprisingly quickly.
This is especially important for newly planted trees, shrubs and perennials. Their root systems are still establishing, and keeping them adequately watered through fall can help set them up for a healthier winter and spring.
Keep an Eye on Your Containers
Your patio pots may not dry out quite as quickly as they did during the hottest weeks of July and August, but they can still need regular watering in September.
Rather than watering on a fixed schedule, check the soil. Stick your finger an inch or two below the surface. If it still feels damp, give it some time. If it's dry, it's probably time for a drink.
As temperatures cool, you'll naturally find yourself watering less frequently.
Give Your Houseplants a Little Attention
September is also a good time to check in on indoor plants.
As the days shorten, houseplants begin receiving less natural light. Plants that were happy several feet away from a window during summer may benefit from moving a little closer to the light.
It's also a great time to wipe dust from leaves, check for pests, remove yellowing foliage and reconsider your watering routine. Many houseplants begin using water more slowly as we move into fall.
You Don't Have to Cut Everything Back
It's tempting to start cleaning up the garden as soon as things begin looking a little less tidy, but not everything needs to be cut down in fall.
Seed heads and dried stems can provide food and habitat for birds and beneficial insects, while also adding texture and interest to the winter garden.
Remove anything diseased or damaged, but consider leaving healthy perennial growth standing where it makes sense. A slightly less tidy fall garden can be a very good thing.
September Is a Great Time to Plant
While spring gets most of the attention, early fall can be a wonderful time to add perennials, shrubs and trees to the garden.
The cooler temperatures put less stress on plants while the soil is still warm enough for roots to establish before winter.
Just remember: new fall plantings still need water. Cooler temperatures don't eliminate the need for consistent watering while those roots settle in.
Start Thinking About Your Fall Containers
If your summer pots are beginning to look tired, you don't necessarily need to replace everything at once.
Remove plants that are truly finished and keep anything that's still looking beautiful. Then you can slowly transition containers for fall by adding seasonal texture and cooler-weather plants.
Sometimes a few thoughtful changes are all a container needs to carry it through another season.
A Little September Care Goes a Long Way
September isn't quite summer and it isn't quite fall, which is exactly why paying attention to what your plants are telling you matters more than following a strict calendar.
Check the soil. Watch the weather. Keep new plants watered. And don't feel like you need to clean up the entire garden just because fall is approaching.
