Great! Let's make a DIY version of Miracle-Gro Shake ’n Feed / Continuous Release — a granular, slow-release plant food that you can sprinkle around your garden or mix into potting soil.
Miracle-Gro Shake ’n Feed combines synthetic and natural ingredients to feed plants for up to 3 months, often including:
Bone meal
Feather meal
Potash
Microbes or organic matter
| Ingredient | Function | Amount |
|---|---|---|
| Bone meal | Phosphorus, calcium | 1 cup |
| Feather meal or blood meal | Nitrogen (slow-release) | 1 cup |
| Kelp meal | Micronutrients, hormones | ½ cup |
| Greensand or langbeinite | Potassium, iron, magnesium | ½ cup |
| Rock phosphate | Long-term phosphorus | ½ cup |
| Crushed eggshells (optional) | Calcium | ½ cup |
| Compost or worm castings | Microbes + trace nutrients | 1 cup |
🔄 All ingredients can be found at garden centers or online (many are organic fertilizers on their own).
Mix all dry ingredients thoroughly in a bucket or large bowl.
Store in an airtight container (like a plastic tub or jar).
Sprinkle 2–4 tablespoons per plant or 1–2 cups per 10 sq. ft. of soil.
Work into the top inch of soil and water well.
Every 2–3 months
Safe for veggies, flowers, shrubs, trees
Ideal at planting time or for side-dressing established plants
Adjust ratios depending on whether you're growing leafy greens (more nitrogen), fruiting plants (more potassium/phosphorus), or flowers.
Add a handful of compost when applying to boost microbial life.
Store cool & dry — moisture can activate nutrients too early.
