Here are are few tips to use recycled plastic jugs in your garden!
1. Use gallon bottles/jugs and cultivate what you want.. ideal for anyone who lives in an apartment or small area.
2. Cut the bottom off your gallon milk jugs (and save the bottoms ... you'll see why!) and use them as cloches in the garden! Place them over young tomato, pepper, and other plants, to protect them from frost on chilly spring nights.
3. Slice off the bottom inch or two of your milk jugs, and use them as a tray for starting seeds. Use the top sections as cloches, and you've gotten two great uses out of every milk jug! Poke a few holes in the bottom for drainage, add potting soil or seed starting mix, and plant seeds.
4. Don't spend a bushel of cash on upside-down vegetable planters. You can make them from milk jugs.
5. Slice milk jugs at an angle and you have an instant scoop, complete with handle. Just make sure you leave the lid on! This works perfectly for grass seed, fertilizer, potting soil, and even bird seed! For smaller jobs, use half-gallon jugs.
6. For liquid fertilizer, plant food, herbicides, or other chemicals that need mixing with water, use a milk jug! Measure and add the first ingredient to an empty milk jug, set it on a level surface, and use a permanent marker to make a line at the top of the liquid. Write the ingredient name in the space it occupies in the jug. Add other ingredients as needed, one at a time, marking and labeling after each addition. Next time you make the mix, you won't have to measure. Just use the markings on the milk jug! To avoid mixing chemicals that shouldn't be mixed, reserve one milk jug for your plant food, another for herbicides, and so on, and label them clearly.
7. Punch a series of small holes in the top of a gallon or half-gallon milk jug, fill with water, and use in place of a watering can! The half-gallon size works great for children or anyone who can't manage a heavy full gallon. The water comes out slowly, so kids are less likely to drown plants. If you have to transport water to a garden or flower bed, use a solid lid to haul the gallons of water, and replace it with a hole-punched lid once you get there!
8. Gallon milk jugs are big enough to plant tomatoes. Can hang on deck or wall.
9. Poke tiny holes in the bottom of the jug and place next to new plants.
