We bought an expensive planter ($65) from Bunnings some time ago.  A long trough thing about one and a half feet deep.

Had little lluck with it apart from silverbeet.   Tomatoes did no good in it.

Will try some of the tricks that have been posted.

Those hanging tomato bags things we found useless.  Others may find OK but we threw them away.

What the heck is organic water?

If you mean rain water then it is not organic and I save it as our household water. It measures at 6.5 acid as neutral is 7.

Organic is the yuppy word of the 21st century and it is almost impossible to produce a truely organic vegie or egg or meat because insects crawl and fly around and can be ingested. Chook foods mostly contain grains from all types of plants and not stated as organic. 

I saw a picture recently of Crocs (the footware) nailed to a wall and used as planters.

The Crocs were all colours as were the flowers.

Abby may be able to find it on line somewhere.

They did not look too bad but the right location would be the thing.

I would think they were either cheap imitations or the owner had plenty of money to spare as  true crocs are over $ 60.00 dollars a pair for adults.

Banana trunks are able to hold water thus a good idea to use them as containers. Cut out some holes as shown in photo, add soil, compost, etc. then plant your vegs.

I grow Oregano and mint but they can take over if not contained. I also have chives, brahmi growing.

Have also put in lebanese eggplant and they are growing like a champion. I will ne inundated with eggplant which  can be fried, roasted or used instead of lasagne sheets once fried slightly.

I have had best results growing grape or small tomatoes. No luck with larger ones.

Trying cucumbers to but they newly planted.

It gives me great delight in growing my own veg and giving excess friends.
