Plant tomatoes deep—roots will grow along the stem for a stronger, more productive plant.
💧 Watering Tricks That Save Time & Plants

Repels ants, snails, and cats. Plus, it boosts nitrogen levels for your plants.
11. Companion Planting for Pest Defense
Marigolds deter aphids, basil protects tomatoes, and nasturtiums lure pests away from veggies.

Stick forks (tines up) into your soil to keep critters like squirrels and cats away. Surprisingly effective!
🌿 Weed & Soil Management
13. Newspaper Mulch
Lay newspaper under mulch to smother weeds and retain moisture—biodegradable and cheap.

16. Banana Peel Fertilizer
Chop up peels and bury them in the soil—or soak them in water for a potassium-rich plant tonic.
17. Eggshell Seed Starters
Start seedlings in eggshell halves. When ready, plant them whole—no waste, just calcium boost.

Let veggie or pasta water cool and use it to water plants. It’s loaded with nutrients!
🧰 DIY Tool Hacks
19. Oil-Sand Tool Cleaner
Store your gardening tools in a bucket filled with sand and a bit of mineral oil. It cleans and prevents rust.

Better drainage, fewer weeds, and less bending. Ideal for beginners and small-space gardeners.
