Garden Lovers! As the seasons change across the United States, there are new ways to care for your plants. Here's what's worth knowing this week.
PlantUSA: Why Are Your Tomato Leaves Turning Yellow?
Learn how watering, nutrient availability, and common plant problems can affect tomato leaves—and what to check first.
As October arrives across the United States, cooler temperatures and shorter days can leave tomato gardeners wondering what's happening to their plants. At PlantUSA, we're here to help you understand the signs and figure out what your garden needs.
## Main Reasons Why Tomato Leaves Turn Yellow in October
1. Natural Aging and End of Season
Tomatoes are warm-season annuals. As October brings cooler temperatures and shorter days, older plants naturally begin to decline, especially as the growing season comes to an end.
2. Cooler Weather and Chilly Nights
Cool nights can slow tomato growth and contribute to yellowing or purplish leaves. The effect depends on local temperatures and the plant's condition.
3. First Frost Damage
Frost can damage tomato leaves, causing them to become discolored, water-soaked, or darkened. Check your local forecast to help protect plants before freezing temperatures arrive.
4. Late-Season Diseases and Nutrient Problems
Diseases such as early blight and Septoria leaf spot can cause yellowing and spots, particularly on lower leaves. Nutrient deficiencies and watering problems can also contribute, so check the symptoms before deciding on a cause.
## A Little Help From PlantUSA
Not every yellow leaf means your tomato plant is in trouble. Consider the weather, inspect the leaf patterns, and check soil moisture before taking action.

# 10 Perennials You Can Cut Back in October (And How to Do It!)
PlantUSA | Your friendly guide to a healthier, happier garden
Has your beautiful summer garden started looking a little messy? Yellow leaves, drooping flowers, and brown stems can make you want to grab your pruners and cut everything down. But hold on! Some perennials benefit from an autumn trim, while others provide shelter and food for wildlife through winter.
Here are 10 common perennials you can consider cutting back in October.
## 1. Peonies
Once the foliage turns brown or diseased, cut the stems close to the ground. This helps remove diseased plant material before winter.
## 2. Hostas
After frost damages the leaves, remove the dead foliage. This keeps the garden tidy and helps reduce hiding places for slugs.
## 3. Daylilies
Trim yellowing or dead leaves near the base. Remove healthy green foliage only when necessary.
## 4. Bearded Irises
Remove dead leaves and diseased material, but avoid cutting healthy foliage too aggressively. Good airflow helps keep rhizomes healthy.
## 5. Bee Balm
Cut back diseased or badly affected stems. If the plant is healthy, leaving some seed heads can provide winter interest and wildlife value.
## 6. Garden Phlox
Remove stems affected by powdery mildew and dispose of diseased debris. Healthy stems can be cut back once they die naturally.
## 7. Catmint
Give catmint a light trim if it looks untidy, but avoid cutting deeply into old, woody growth.
## 8. Yarrow
Remove damaged foliage and unwanted spent flower stalks. You can leave some healthy seed heads for birds and winter interest.
## 9. Black-Eyed Susans
Cut back diseased or collapsing stems, but consider leaving healthy seed heads for birds to enjoy.
## 10. Coneflowers
Don't rush to remove every flower head! Their seeds are a valuable food source for birds. Cut back diseased stems and leave healthy seed heads standing.
## A Little PlantUSA Tip for loyal readers
Before you start pruning, check your local weather and growing conditions. In colder regions, October may be ideal for cutting back certain perennials, while warmer areas may need a different schedule.
Remember: A tidy garden doesn't have to be a completely bare garden. Leave healthy seed heads where practical, clean your tools, and remove diseased debris.
