Congratulations to all of Mukwonago graduates but especially to those that have worked with us in the past and present! Addison Burns, Holly Bonesteal, Jackson Cook and Mandy German!!!!
So glad to have worked with these great kids!

🌅➡️🌇 It started with a sunrise...and now it's ending with a sunset.

On the first day of school, our seniors gathered for Senior Sunrise, full of excitement for the year ahead. Now, as the sun sets on their high school journey, they came together one last time for Senior Sunset, a chance to reflect on the memories, friendships, accomplishments, and moments that made their time here unforgettable.

While this sunset marks the end of one chapter, it's also the dawn of countless new adventures waiting just beyond the horizon. ☀️🎓

Congratulations, Class of 2026! We can't wait to celebrate all you've achieved at graduation this Sunday.

Most "lavender" purchased at American garden centers is not the kind recipes call for — and many gardeners never find out until the shortbread tastes medicinal. Three types sit side by side on the same bench looking nearly identical. They are not. 🌿

English lavender (Lavandula angustifolia) — the only one for cooking. Low camphor, clean floral flavor, true lavender scent. Hardy in zones 5–9. Compact plant with short dense flower spikes and no bracts. Varieties worth growing for culinary use: Hidcote, Munstead, Royal Velvet, Folgate.

Spanish lavender (Lavandula stoechas) — immediately identifiable by the two or more large petal-like bracts standing up from the tip of the flower head like rabbit ears. Hardy in zones 7b–10 only. High camphor content makes it harsh for cooking. It thrives in heat and humidity where English lavender struggles, which is why it dominates the Southeast market. Also sold as French lavender, butterfly lavender, or rabbit-ear lavender — do not let the label mislead you.

Lavandin (Lavandula × intermedia) — a sterile hybrid between English lavender and spike lavender. The largest of the three: two to three feet tall, flower spikes on long bare stems, noticeably bigger plant overall. Hardy in zones 5–9. Blooms later than English lavender. Very high camphor and borneol content produces a sharp medicinal flavor — not for cooking. Most of the commercial lavender oil and lavender sachets on the market come from lavandin, not from true lavender. Grosso, Provence, and Phenomenal are all lavandin varieties. 🌱

The identification shortcut: look at the flower head. No bracts and short compact spike = English lavender. Rabbit-ear bracts on top = Spanish lavender. Tall spike on a long bare stem and notably large plant = lavandin.

The tag often says only "lavender." Read the botanical name — Lavandula angustifolia is the one you want for the kitchen.

One tip that protects more plants than zone charts: lavender dies in winter from wet roots, not from cold. Drainage matters more than zone.

You've been watering perfectly. The schedule is consistent, the amount is right, but your plant is dying anyway. Here's the plot twist nobody warns you about: the potting mix itself has an expiration date.

Fresh out of the bag, quality potting mix is about 50% air by volume. Those gaps between peat moss fibers and bark chunks? That's where roots actually do their living. They don't just drink water—they breathe oxygen between waterings. But after 2-3 years in the same pot, the organic materials start breaking down into particles so fine they collapse into each other like a slow-motion avalanche. What used to be fluffy architecture becomes dense clay-like mass.

The real kicker is how sneaky this transformation is. You water your plant and suddenly the water races around the edges and straight through the drainage holes. The top inch dries out fast, so you water again. But slice that rootball open and you'll find the center is either bone-dry dust or a wet, airless brick—depending on whether water could even pe*****te. Your plant is simultaneously drowning and dying of thirst.

Roots need oxygen as desperately as they need water. In compacted mix, there's nowhere for oxygen to live. Root tips hit that dense zone and literally suffocate. The plant starts showing those maddeningly vague symptoms—yellowing leaves, stunted growth, that general look of "I'm not thriving but I'm not dead yet." You troubleshoot everything except the one thing that's actually broken: the medium itself.

Most houseplants need completely fresh potting mix every 2-4 years, regardless of pot size. It's not about root space. It's about restoring those invisible air channels that make soil actually function like soil.

When's the last time you gave your oldest plant a complete mix refresh? [2M6DO]
