Myth or Fact: Native plants don't require any watering or maintenance once planted.

FACT OR MYTH?
Myth!

While native plants are adapted to local soil and climate conditions and generally require less long-term care than non-natives, they still need regular watering during their establishment period—typically their first 1–2 growing seasons.

Why This Matters for Zone 7a:

Establishment Phase: During late summer heat in Zone 7a, newly planted native perennials, shrubs, and trees need deep, consistent watering until their root systems expand.

Seasonal Care: Mulching, w**d management, and occasional pruning keep native beds healthy, neat, and thriving year-round.

Drought Resilience: Once fully established, native plants will withstand local heat and dry spells much better, but they aren't completely "set-and-forget" on day one.

Invasive plant species can quickly transform a balanced, healthy ecosystem into a nightmare. Many native pollinators and caterpillars depend exclusively on native plants for food and nesting - when invasives take over, they displace these foundational plants, causing a collapse in the food chain. Which ones are in our area? How do we distinguish them from native plants? And how in the world do we get rid of them?
Join us for a 2 hour workshop on Thursday, Sept. 24th from 10-12 at the Carver Center on Rte. 15, and learn how you can identify and control the invasives in your area. Space is limited, so sign up now at

Can you identify this striking insect? 🐛✨

Appearance: Bright green "saddlecloth" pattern across its middle with a dark purplish-brown oval spot in the center, flanked by prominent horns lined with menacing spines.

Habitat: Common throughout gardens, deciduous woods, and fields in eastern North America.

Warning: Handle with care! Those spiky horns contain venomous, stinging hairs (urticating spines) that can pack a surprisingly painful punch if brushed against.

Myth or Fact: Pawpaw trees need to be planted in deep shade to survive.

MYTH!

While young pawpaw (Asimina triloba) saplings prefer shade for their first year or two to protect delicate young foliage, mature trees produce the best harvest when grown in full sun with adequate moisture.

The Details:

Young Saplings: Need partial shade during their first 1–2 years because their tender leaves burn easily in high heat and strong direct sunlight.

Mature Trees: Once established, full sun fuels lush growth, stronger branching, and significantly maximum fruit production.

Pollination Tip: Plant at least two genetically distinct trees (different varieties or seedlings from different mother trees) nearby—pawpaws are not self-fertile, and they depend on beetles and flies for pollination!

Have a pawpaw patch in your yard? Let us know in the comments how your trees are performing this season!

🌿 Lenn Park Native Garden Workday

Monica, Ericka, and Cindy spent some time w**ding and maintaining the native gardens at Lenn Park. They filled three 40-gallon bags with w**ds and garden debris! 💪🌱

They also worked on prepping garden beds for Monarch Waystation certification and for lots of fall planting coming soon. 🦋🌼

Regular maintenance like this helps keep the garden healthy, gives our Virginia native plants room to thrive, and keeps the space welcoming for park visitors and pollinators.

Thank you, ladies, for helping move this garden forward! 💚

🔍 Guess That "Bug"! 🕵️‍♂️🌱

This week's mystery garden creature leaves behind a few distinctive clues:

The Damage: Leaves that look "sandblasted," showing fine stippling, yellowing, or a bronzed/bleached appearance.

The Tell-Tale Sign: Fine, delicate silk webbing spanning across the undersides of leaves and stems.

Plot Twist: Despite what people call it, it isn't actually an insect at all! It has 8 legs, a single oval body section, and no antennae or wings.

The Paper Test: If you shake an infested leaf over a blank sheet of white paper, you'll see tiny specks—no bigger than the period at the end of this sentence—crawling around.

Can you guess who's been sapping the life out of your plants? 🤔
