💡 Grandmaw's Tips

🌱 Rosemary hates wet feet more than anything. If your plant dies, it was probably overwatering, not neglect. Let the soil dry out between drinks.

🌱 Don't bother with seeds unless you have the patience of a saint. Buy a small plant or root a cutting from a friend's bush — it's faster by months.

🌱 Bring potted rosemary indoors before the first hard frost in cold zones. A sunny south-facing window and very little water will keep it alive all winter.

🌱 Harvest by cutting whole sprigs rather than picking individual needles. Cut from the tips and never take more than a third of the plant at once.

🌱 If your rosemary gets leggy and woody in the center, give it a hard prune in early spring — cut back by about a third. It'll push out fresh, bushy growth.

🌱 A mature rosemary bush can give you more herb than you'll ever use fresh. Dry the surplus — it keeps its flavor for a solid year in a sealed jar.

Here's how to keep rosemary all year long.

🧊 Freezing (Whole Sprigs)

6-12 months

Best for: Roasts, soups, braises — anywhere you'd use a whole sprig

💡 Lay sprigs flat on a sheet pan, freeze solid, then toss in a freezer bag. They crumble right off the stem when you need them — no thawing required.

🧊 Freezing (Herb Butter Logs)

6 months

Best for: Instant flavor for steaks, bread, roasted vegetables

💡 Mix minced rosemary into softened butter, roll in parchment into a log, and freeze. Slice off coins whenever you need a hit of flavor.

🌬️ Air Drying

1-2 years

Best for: Seasoning blends, rubs, everyday cooking

💡 Bundle 4-5 sprigs together, hang upside down in a warm dry spot for 1-2 weeks. Strip the needles and jar them up. This is the easiest herb to dry.

🫒 Oil Infusion

2-4 weeks (refrigerated) or 6+ months (properly strained and frozen)

Best for: Bread dipping, salad dressing, roasting

💡 Warm olive oil gently with rosemary sprigs for an hour or two. Strain out all the plant material before storing — this is important for safety. Keep it in the fridge.

🧂 Rosemary Salt

12+ months

Best for: Finishing salt for meats, eggs, roasted potatoes, bread

💡 Pulse dried rosemary with coarse salt in a food processor until blended. Four parts salt to one part rosemary. Jar it up — makes a beautiful gift too.

🫙 Vinegar Infusion

6-12 months

Best for: Salad dressings, marinades, deglazing pans

💡 Push 3-4 fresh sprigs into a bottle of white wine vinegar and let it sit for 2-3 weeks. Strain if you like, or leave the sprigs in — they look pretty.
