🌱 Dry shells completely in the oven at 200°F/95°C for 10 minutes before crushing. This makes them brittle and prevents clumping.
🌱 Store your powder in an airtight jar labeled “Garden Calcium” so family members don’t mistake it for flour!
🌱 Combine with coffee grounds for a balanced calcium + mild acidity boost that blueberries and azaleas adore.
🌱 Start a “shell jar” on your counter. Once it’s full (about 30–40 shells), process the whole batch in one go. Takes 20 minutes max.
Watch the Transformation Happen
Within weeks, you’ll notice stronger stems, glossier leaves, and fruits that develop perfectly round and firm instead of deformed. Your tomato yield can increase by 20–30% in calcium-poor soils. Flowers last longer in vases when grown with eggshell-fed plants. Even houseplants perk up when you sneak a teaspoon into their pots every few months.
All from something you were throwing away yesterday.
Your Next Move
Tonight, when you boil eggs for dinner or tomorrow’s lunch, keep those shells. Start your first batch. In less than 20 minutes of total effort spread over a week, you’ll have a jar of pure garden gold sitting on your shelf.
Then stand back and watch your plants thank you in the most delicious, beautiful way possible.
Because the best fertilizer isn’t the one with the fanciest bag or the highest price tag.
It’s the one you were about to throw in the trash.
