This comprehensive guide to container gardening is perfect for eco-conscious gardeners, beginners with limited outdoor space, and anyone looking to repurpose household items into productive growing containers. Whether you want to start seeds indoors, grow fresh herbs on your kitchen windowsill, or cultivate root vegetables like carrots and parsnips, these creative container gardening ideas will help you garden sustainably while reducing waste.
‘Early Nantes’ Carrots Growing in Terracotta Pots
Here are a few container gardening ideas for you to consider. In the green spirit of recycle, reuse and reduce, these suggestions make use of items you might normally throw away.
How to Use Egg Cartons for Starting Seeds Indoors
Egg cartons are great for starting seeds indoors while it’s still too cold to plant outside. The ones made of thick paper or cardboard are best for this purpose – they can be added to the compost heap later. Other types too can be used eg those made of plastic, as long as you make some drainage holes. A knitting needle is just about the right size for making holes.
You can line the inside of the containers with paper towels to prevent soil loss through the drain holes. Your kitchen counter can double as your greenhouse. You can place the cartons on bath towels to absorb any excess liquid.
Fill each egg indentation with a couple of tablespoons of potting soil or growing mixture.
Be careful not to become confused and sprinkle it on your cereal as roughage ;0)…
Place one or two seeds in each space, depending on the type of plant. Add water and sunshine. Your seeds will sprout and be ready for transplanting after the threat of frost has passed. If you clean and dry your plastic ones, you can develop a recycled gardening container supply, reusing the cartons next year.
According to the National Gardening Association, container gardening has increased by over 46% in popularity since 2008, with millions of households now growing vegetables and herbs in repurposed containers to reduce waste and increase food self-sufficiency.
Examples Of Gardening Containers
Repurposing Food Containers for Growing Vegetables and Herbs
Tin, aluminum and plastic containers like coffee cans make useful containers. This container gardening idea keeps them from ending up in the landfill. Other food containers can be used, too. Anything large enough to accommodate the plant will work, as long as you add drainage holes.
My suggestion is to look at all food containers before you throw them away and evaluate their usefulness. Small containers such as those that hold cottage cheese can be used for herbs. If you want to maintain a certain colour scheme or appearance, you can easily paint the containers with non-toxic paints – your kids would enjoy doing this and then they could follow up with sowing some seeds into their new container garden creations.
Using Old Belfast Sinks as Deep Planting Containers
A great container gardening idea is an old sink – belfast sinks are ideal – perfect for root crops like carrots (I only grow Early Nantes carrots in containers – throughtout the summer). Leave the sink as you find it, if it fits in, but you can also apply hypertufa treatment to it, a way of making it look and weather like stone.
Hypertufa consists of cement, sand and fine peat blended together with water to make a moist consistancy. The surface of the sink is covered with a bonding material and left to go tacky. The hypertufa mix is then applied all over the surface. Again you can be creative here and press shells etc into the surface or etch a design over the surface. Painting the surface with something like yogurt will encourage moss to develope.
Stacking Used Tyres for Deep-Root Vegetable Gardening
You might think that vegetable container gardening is quite restricted in getting the depth required by some vegetable plants – for growing carrots or parsnips…
Not so!
Old tyres are great garden containers because they can be stacked to create the depth required – to make them more attractive (if that were possible :0 ) try a coat of paint.
How about an old wheel barrow, recycle old wood to make boxes, concrete blocks, I’ve even seen a picture of an old rowing boat brought into use as usefull container gardening idea – ideal if your prone to flooding…
How to Start Composting in Recycled Coffee Cans
A large plastic coffee-can will work well for composting. This container gardening idea will allow you to make your own fertilizer. You will need to drill holes all around the can to allow air to circulate.
You might want to keep the can or cans outside, because they can start to smell as vegetable peels and other items start to decompose. You’ll need to add a little dirt to the pot in order for the composting process to begin.
When you are ready to plant, you will mix one part compost with two parts soil or growing medium. You have made your own organic fertilizer and reused even more garbage. I hope you have enjoyed these green container gardening ideas. You’ll enjoy your vegetables even more if you feel good about the whole process.

What vegetables grow best in containers?
Root vegetables like carrots (especially Early Nantes varieties), parsnips, and radishes thrive in deep containers such as stacked tyres or Belfast sinks. Herbs, lettuce, tomatoes, peppers, and beans also perform exceptionally well in container gardens when provided with adequate drainage and the right-sized container for their root systems.
How do I add drainage holes to recycled containers?
For plastic containers, use a drill with a small bit or heat a nail to melt holes through the bottom. For metal containers like coffee cans, a hammer and nail work well for punching drainage holes. Aim for several holes spaced evenly across the bottom to ensure proper water drainage and prevent root rot.
Can I grow vegetables in egg cartons permanently?
Egg cartons are designed for seed starting only, not permanent growing. Once seedlings develop their first true leaves and the threat of frost has passed, they should be transplanted into larger containers or garden beds. Cardboard egg cartons can be planted directly into soil as they will decompose naturally.
Is it safe to grow food in old tyres?
Growing food in tyres is a debated topic among gardeners. While tyres are widely used for container gardening, some gardeners prefer to use them only for ornamental plants or line them with landscape fabric as a precaution. If concerned, reserve tyre planters for flowers and use food-safe containers for edibles.
What is the best soil mix for container vegetable gardening?
A quality potting mix combined with compost works best for container vegetables. The recommended ratio is two parts potting soil or growing medium to one part compost for optimal nutrition and drainage. Avoid using garden soil alone as it can compact in containers and restrict root growth.
How often should I water vegetables in containers?
Container plants typically need more frequent watering than garden beds because they dry out faster. Check soil moisture daily by inserting your finger an inch into the soil—if it feels dry, water thoroughly until it drains from the bottom holes. During hot summer months, you may need to water twice daily.
Can children help with container gardening projects?
Container gardening is an excellent activity for children of all ages. Kids can help paint recycled containers with non-toxic paints, sow seeds into their creations, and monitor plant growth. This hands-on experience teaches valuable lessons about sustainability, food production, and the natural world while keeping them engaged outdoors.
