Old inner tubes make strong rubber bands - slice at different angles for different sizes.
Underneath the kids trampoline makes a great extension to the chicken run.
Old tent poles for staking Hollyhocksand such - the good thing is you add each new length as the plant grows this way you don't have a field of sticks to look at all spring.
A paper potter can be made easily from a short length of tube and a slightly narrower length of wood. If your interested - what you do is take a strip of newspaper and roll it on to one end of the tube so that the paper overlaps the tube then stuff the exess backinto the tube and use your stick to tamp down the newly formed pot. Its a work of seconds. (To make it stronger before you roll it you can fold a 1 cm edge along the length of the paper where the lip of the pot is to be. To make it even stronger you can fold the tail end in half to make a diagonal finish to the paper)
To save on pruning all you need is a ball , a boy and his mates.
An old tee shirt cut into inch wide strip and rolled into a ball is good for tying up tomatoes Sheila
I'm trialling a new method of keeping the greenhouse warm at night. Having collected plastic milk bottles and filled them with rain water, I have placed them under potting benches in the greenhouse so that they absorb heat from the sun in the day and slowly release it at night. This will also provide a store of water which I can use to water plants if we have a dry spell.
I use an empty, washed out plastic milk bottle as a scoop for putting soil into plant pots.
Instructions - turn the plastic bottle upside down with lid on. Cut a slant edge from the bottom.Hold the handle and happy gardening .
Farmers are quite pleased to see the back of their empty liquid fertalizer containers and they make a great 1000 litre water storeage tank. Along with old dustbins which freestand about in my alloment.
I re-use old margerine containers as mini seed propagators. Clean them thoroughly and put some holes in the base. Cut out most of the centre portion of the lid using a craft knife or sharp scissors, leaving a frame around the edge. The design on the top usually gives a neat template for this. Fill the pot with compost, sow your seed and cover with cling film. Replace the lid, which then creates a tight seal. You can easily see progress through the cling film.
In then cut the discarded top into 3 strips to use as markers, using a chinagraph pencil or marker pen.
I also clean and re-use supermarket meat trays. The opaque ones make good drip trays. match them to fit your seed trays, margerine containers or modules (I save the ones I buy seedlings in, with careful handling they last several years and save ££s).
The clear plastic ones make excellent propogator tops - again match them to the bottoms and you get a snug fit.
We don't buy expensive canes from the garden centre. We got ourselves a non-invasive variety of bamboo which grows at the back of the garden & acts as a screen - it's so easy to use the mature canes from that each year for plant supports, plus they can be bent when freshly cut, and the used dried out canes are good for making homes for overwintering insects.
Join bamboo canes together to provide frames for netting etc, by using old tennis balls with slits cut to take the canes, instead of buying the expensive rubber balls and other fixings. (If you haven't got a tennis player in the family, you can get packs of cheap balls from pound shops).
Take a tip from fishermen and repair torn netting instead of buying more.
Shake the worst of the dirt from fleece and put in the washing machine to use again.
Use clothes pegs for holding fleece, netting, etc. to canes.
Put EMPTY snail shells on the top of canes as eye protectors.
Salvage(or scrounge from furniture shops) large pieces of polythene from large delivered items (e.g. beds) to use as covers for 'tunnels' (made from salvaged wire coathangers).
I lost two lots of young healthy pea seedlings in my greenhouse a couple of years ago (mice, I think!) so I salvaged some plastic runged shelves from fridges in my local council dump. I placed long bamboo canes through the metal bars in the eaves of my greenhouse and hung the shelves on with sturdy twine. The seedlings thrived and were out of the way of any rodents.
