We get questions all the time about growing your own food at home. This section will provide several options to grow food at home if you wish. If you don't find an answer here, drop us a line.
Celery is one of the easiest foods to grow from leftover scraps. Just cut off the bottom or base of your celery and lay it in a bowl with just a bit of warm water in the bottom. Keep the bowl in direct sunlight as long as possible each day and after about a week, you will begin to see the leaves thickening and growing along the base. When this happens, you can transplant your celery in soil and wait for it to grow to full length.
If you love using lemongrass but have a difficult time finding it, simply regrow your own. Lemongrass will grow just like regular grass. You just place the root that is leftover in a glass bowl or jar with enough water to cover it and leave it in the sunlight. After about a week, you will notice new growth and when this happens you can transplant your lemongrass in a pot or in your herb garden.
Leeks, Scallions, Spring Onions and Fennel
You can either use the white root end of a vegetable that you have already cut, or buy a handful of new vegetables to use specifically for growing.
Simply place the white root end in a glass jar with a little water, and leave it in a sunny position. I keep mine in the kitchen window. The green leafy part of the plant will continue to shoot. When it’s time to cook, just snip off what you need from the green growth and leave the white root end in water to keep growing. Freshen up the water each week or so, and you’ll never have to buy them again.
Ginger is very easy to re-grow. Simply plant a spare piece of ginger rhizome (the thick knobbly bit you cook with) in potting soil with the newest (ie. smallest) buds facing upward. Ginger enjoys filtered, not direct, sunlight in a warm moist environment.
Before long it will start to grow new shoots and roots. Once the plant is established and you’re ready to harvest, pull up the whole plant, roots and all. Remove a piece of the rhizome, and re-plant it to repeat the process.
Ginger also makes a very attractive house-plant, so if you don’t use a lot of ginger in your cooking you can still enjoy the lovely plant between harvests.
Re-growing potatoes is a great way to avoid waste, as you can re-grow potatoes from any old potato that has ‘eyes’ growing on it. Pick a potato that has robust eyes, and cut it into pieces around 2 inches square, ensuring each piece has at least one or two eyes. Leave the cut pieces to sit at room temperature for a day or two, which allows the cut areas to dry and callous over. This prevents the potato piece from rotting after you plant it, ensuring that the new shoots get the maximum nutrition from each potato piece.
Potato plants enjoy a high-nutrient environment, so it is best to turn compost through your soil before you plant them. Plant your potato pieces around 8 inches deep with the eye facing upward, and cover it with around 4 inches of soil, leaving the other 4 inches empty. As your plant begins to grow and more roots appear, add more soil. If your plant really takes off, mound more soil around the base of the plant to help support its growth.
You can re-grow a plant from just a single clove – just plant it, root-end down, in a warm position with plenty of direct sunlight. The garlic will root itself and produce new shoots. Once established, cut back the shoots and the plant will put all its energy into producing a tasty big garlic bulb. And like ginger, you can repeat the process with your new bulb.
Onions are one of the easiest vegetables to propagate. Just cut off the root end of your onion, leaving a ½ inch of onion on the roots. Place it in a sunny position in your garden and cover the top with soil. Ensure the soil is kept moist. Onions prefer a warm sunny environment, so if you live in a colder climate, keep them in pots and move them indoors during frostier months.
As you use your home-grown onions, keep re-planting the root ends you cut off, and you’ll never need to buy onions again.
When planted, sweet potato will produce eye-shoots much like a potato. Bury all or part of a sweet potato under a thin layer of soil in a moist sunny location. New shoots will start to appear through the soil in a week or so. Once the shoots reach around four inches in height, remove them and re-plant them, allowing about 12 inches space between each plant. It will take around 4 months for your sweet potatoes to be ready. In the meantime, keep an eye out for slugs… they love sweet potatoes.
To propagate sweet potatoes, it is essential to use an organic source since most commercial growers spray their sweet potatoes to prevent them from shooting.
Mushrooms can be propagated from cuttings, but they’re one of the more difficult vegies to re-grow. They enjoy warm humidity and nutrient-rich soil, but have to compete with other fungus for survival in that environment. Although it is not their preferred climate, cooler environments give mushrooms a better chance of winning the race against other fungi.
Prepare a mix of soil and compost in a pot (not in the ground) so your re-growth is portable and you can control the temperature of your mushroom. I have found most success with a warm filtered light during the day and a cool temperature at night. Just remove the head of the mushroom and plant the stalk in the soil, leaving just the top exposed. In the right conditions, the base will grow a whole new head. (In my experience, you’ll know fairly quickly if your mushroom has taken to the soil as it will either start to grow or start to rot in the first few days).
To re-grow pineapples, you need to remove the green leafy piece at the top and ensure that no fruit remains attached. Either hold the crown firmly by the leaves and twist the stalk out, or you can cut the top off the pineapple and remove the remaining fruit flesh with a knife (otherwise it will rot after planting and may kill your plant). Carefully slice small, horizontal sections from the bottom of the crown until you see root buds (the small circles on the flat base of the stalk). Remove the bottom few layers of leaves leaving about an inch base at the bottom of the stalk.
Plant your pineapple crown in a warm and well drained environment. Water your plant regularly at first, reducing to weekly watering once the plant is established. You will see growth in the first few months but it will take around 2-3 years before you are eating your own home-grown pineapples.
