Gardeners are a resourceful bunch, making the most of what's to hand and taking the time to get more from less. Perhaps it's because patience is such an integral part of what we do – after all, even the quickest vegetables still take weeks from sowing to harvest.
Recycling waste in the garden certainly gives me a great sense of satisfaction. The fact that I've rescued something destined for oblivion and turned it to practical use while saving a little money in the process is immensely gratifying. And it's easy! All that's needed is a raid of the recycling pile for easy-to-convert pots, seed trays and more.
Recycled Containers for Seed Sowing
Seed sowing is a great place for recycling-in-the-garden newbies to start. Many repurposed containers can be used immediately, while others require just a few tweaks before they are ready for sowing into. You can also get creative by painting or accessorizing chosen containers to look fabulous and funky – bespoke containers as extrovert as you care to make them!
Old yogurt pots are the ideal size for sowing small clusters of seeds or larger seeds individually. Before using them you will need to punch some drainage holes into the bottom. I use a sharpened kebab skewer for this purpose, pinning the pot down and needling the holes through the bottom as I twist. You could also use a power drill, holding the pot onto a supporting stump or wood block as you drill.
Fruit punnets – the types that raspberries and other soft fruits are often sold in – make excellent miniature seed trays. Many already have holes in the base, allowing a quick turnaround for sowing. Clear plastic trays also make handy miniature greenhouses or sprouting trays.
Toilet roll tubes give extra root depth, which is ideal for deeper-rooted vegetables such as peas, beans and corn. Pack them into a supporting tray, cheek by jowl, so that the sides remain intact and don't collapse when saturated. The great thing about toilet roll tubes is that they can be planted out as they are – the cardboard simply rots away.
Old polystyrene drinks cups – the sort hot drinks are served in – make excellent pots for young plants. They are a decent size and the polystyrene helps to insulate the roots against cold. Create drainage holes by pinching three or four holes into the base of the cups at the sides.
How to Make Paper Pots
Even your daily read can be reinvented for sowing. Paper pot makers – also known as paper potters – can turn newspapers into handy little propagation pots in seconds. But you can do without if you're not planning on production-line quantities.
Simply fold a page in half lengthways then roll it around a toilet roll tube so that the tube sticks out above the folded edge of the paper; this will be the rim of your pot. Now gather up the loose ends of the paper at the bottom and push them into the base of the tube to form the bottom of your pot. Slide out the toilet roll tube then flatten out the base of your pot by simply filling it with compost/potting soil ready for sowing. Just like sowing into toilet roll tubes, I sit them side-by-side within a tray so that they are supported and can't fall apart.
How often have you sown your seeds, watched them germinate then forgotten which seedlings were which? This has happened to me on more than one occasion! The solution, of course, is to label everything – and I mean everything – with the variety of the crop and the sowing date.
Make your own plant labels by cutting out strips of white yoghurt pot or repurposing wooden lollipop/ice cream sticks. Write onto plastic labels with a marker pen.
Seeds sown directly into the ground can be labeled using lengths of wooden batten, cut into foot-long sections then pushed into the ground. If you have the time, inch-wide prunings shaved to expose a flat, writable surface, make for an incredibly attractive semi-permanent solution.
Home-made Miniature Cloches
Germination can be greatly improved with the addition of a little warmth. Any clear plastic or glass cover can help to trap the sun's heat and create a greenhouse effect, warming the soil and coaxing seeds from their slumber. This includes, for example, old panes of glass placed over seed trays, or clear plastic drinks bottles cut in half to make miniature hot houses that can then be popped over individual plants or pots of seedlings. Simple yet very effective.
Another handy tip to help your seedlings along is to use reflectors to bounce back light. This is particularly useful for windowsill seedlings, which inevitably lean towards the light, necessitating regular turning of the seed tray to balance out the growth. Make a reflector by wrapping a suitable vertical surface with aluminum foil, shiny side facing outwards. Place this opposite the window to reflect back some of the light and reduce the leaning effect. You could even line an open-sided cardboard box this way to create a self-contained natural light chamber.
