Ten gardening hacks.

1. Pot shards at the bottom of containers for drainage
2. Coffee grounds for acid-loving plants (blueberries, azaleas)
3. Eggshells for calcium (crushed into soil)
4. Bananas for potassium — chop peels into compost
5. Beer trap for slugs
6. Cinnamon on seedlings to prevent damping-off
7. Self-watering wine bottles for vacation
8. Milk jugs as mini-greenhouses for young plants
9. Newspaper mulch under wood chips
10. Epsom salts for tomatoes (magnesium — if deficient)
