🛑 Don't touch that! Wild parsnip is taking over roadsides and fields! 🛑

As Goodhue County Master Gardeners, we are getting lots of questions about this yellow-flowered hazard. Wild parsnip is an invasive species on Minnesota’s Control Noxious W**d List. It is highly dangerous—its sap reacts with sunlight to cause painful, severe chemical burns and blisters on bare skin.If you find it on your property, here is how the University of Minnesota Extension and the Minnesota Department of Agriculture recommend safely eradicating it:

🛡️ STEP 1: PROTECT YOURSELF FIRST: Never handle this plant with bare skin.Wear long sleeves, long pants, thick gloves, and eye protection.Try to work on cloudy days or after sunset to minimize the risk of sunlight reacting with any accidental sap exposure.

🌱 STEP 2: CHOOSE YOUR ERADICATION METHODFor Small Patches (Hand-Digging): Do not simply pull it by hand. Instead, use a sharp spade or shovel to slice the taproot 1 to 2 inches below the soil surface. This kills the plant and prevents re-sprouting.For Large Infestations (Mowing): Mow stands down in late spring or early summer (May to July) before the flowers go to seed. Mowing kills mature plants and stops seed production. CRITICAL: Do not mow if seeds have already enlarged (July to November), or you will accidentally spread the infestation everywhere!Chemical Control (Herbicides): Apply a selective broadleaf herbicide or glyphosate spot-treatment in the early spring or late fall. This targets the ground-level rosettes and newly bolted plants before they can flower. Always follow the chemical label instructions.

⏱️ THE LONG GAME: Wild parsnip seeds survive in the soil for years. Eradication is a multi-year commitment, so plan to monitor the area and repeat these steps for several seasons to fully exhaust the seed bank.

Check out this great learning opportunity being held June 8th and 9th, at the Universit of Minnesota Landscape Arboretum! See the post below for details.

Next week! Join us on June 8 or 9 to learn about horticulture for resilient landscapes at the Minnesota Landscape Arboretum. This field day will highlight innovative solutions for plant health, production efficiency, and cold-hardy genetics.

Topics include:
- Jumping worms: learn how to identify soil that is not impacted by jumping worms versus soil that has been impacted by jumping worms.
- Prairie willows: see and feel the two types of prairie willow that grow well in Minnesota.
- Mouse ear disorder: view mouse ear disorder on common plants and learn about how to treat it.
- Black walnut: learn about tapping black walnut trees.
- Red start rust on apples: learn the differences between red start rust and cedar apple rust, and see the equipment the researchers use to catch spores for identification.
- Japanese beetles: learn about the interaction between birch trees and Japanese beetles, and how Japanese beetle research is currently conducted.

Optional guided tours of peony and weigela research plots are also available at an additional cost.

This event is open to the public and offers a great opportunity for Q&A with the scientists behind the work! General admission to the Arb is required; free for Arboretum members.

Registration:
June 8, 10 a.m. to 2 p.m.: z.umn.edu/bc94

Thinking about moving your houseplants outside for the summer? ☀️🪴

Before you move them to the patio, remember that most houseplants prefer indirect light and can easily scorch in the harsh summer sun.

Here are three quick tips from University of Minnesota Extension to keep your plants happy:

Morning Sun Only: Place plants where they get sun before noon to avoid hot afternoon burns.

Filter the Light: Use porches, trees, or pergolas to mimic the bright, indirect light they love.

Watch the Water: Outdoor pots dry out much faster than indoor ones, so check soil moisture often!

⚠️ Note: Some sensitive favorites like Peperomia, Calathea, and Fittonia prefer stable conditions and should stay indoors all summer long.

Wild Bergamot (Monarda fistulosa)

🌸 Pollinator Champion Profile: Wild Bergamot 🐝

Looking to add a punch of color that brings your garden to life with activity? Look no further than Wild Bergamot, also known as Bee Balm!

As Master Gardeners, we love this tough, aromatic native perennial because it is a magnet for native bees, bumblebees, butterflies, and even hummingbirds.

According to the University of Minnesota Extension, its unique lavender, tube-shaped flowers are perfectly designed for long-tongued pollinators. Plus, its minty-scented foliage acts as a natural deterrent to deer and rabbits!

🌱 Quick Tips from the U of M Extension:
Light: Full sun to partial shade.

Soil: Adapts well to dry or moist soil, making it highly drought-tolerant once established.

Bonus Tip: Give it plenty of space and good air circulation to prevent powdery mildew.
