Whether you have a big yard or a small urban garden on your patio or a tiny container garden on the balcony you can use these 12 leftover items of your kitchen to encourage the healthy growth of plants.

1. Used coffee grounds


The next time you finish your morning coffee, think twice before you dump the grounds. Coffee grounds can do magic in your garden, not necessarily in the ways you would expect. They do not provide abundant nitrogen and do not lower soil pH much. But they can enrich your garden soil, compost pile and help in other ways. 

2. Egg shells

Mainly calcium carbonate (37%), which is an essential element required for plant’s growth. For your surprise, eggshells also consists magnesium, potassium, iron and phosphorus in good quantity. To this, these are added with 3.3% protein and a trace element manganese.

3. Old milk jug


This super simple hack of an old milk jug is perfect for a new gardener that hasn’t gone out and bought a watering can yet. Just upcycle your old plastic milk jug by heating up a needle and poking holes in the lid so water can flow through it freely.

Just poke a hole in the bottom of the peel for drainage, fill it with potting soil, then sow seed and sprinkle some water. When the seedling is ready for transplant, plant it directly in a garden or in a container with the peel. The peel will decompose and nourish the young plant as it grows. 

5. Used coffee filter in the botton of pot

Next time you’re repotting a plant, keep the soil where it belongs with the help of a coffee filter. Simply lining the pot keeps the drainage holes in the bottom free from clogging up — and soil from sneaking out after watering. 

6. Use cooking water to fertilize plants

When you boil or steam some vegetables on the stove top, don’t pour the water down the drain. Once the water has cooled, pour this vegetable water in your plants to fertilize them instead of wasting it. You can also do the same with your boiled egg water.

7. Benefits of banana peels and orange peels

Before you toss another orange or banana peel into the trash, stop and think about the potential benefits you may be throwing away. Like other kitchen scraps, these peels can be added to the compost bin or used directly in the garden as a replacement for chemical fertilizers or insecticides. 

8. Nutshells are a good addition

The Nut shells are a good addition to your compost heap because they don’t break down as quickly as other items. Nut shells also work well as a mulch, the reason is same– they don’t break down easliy. In compost, they can help vary the thickness of it, this later helps in soil aeration. A warning: don’t use black walnut nut hulls beacuse they have a large concentrations of juglone which is toxic to many plants.

9. Paper Towel Rolls


Instead of throwing out the paper towel roll, use it in the garden. Cut it into peices and press it into the soil around your newly planted seedlings to give them a extra protection from slugs and other ground dwelling pests. You can also use paper towel rolls as seed starters (*you can also use toilet paper rolls).
