I have found that many folk who go camping will purchase a cheap BBQ and then toss it away rather than take it home when they leave.

I found two of them in the hedges and decided they would make great planters so bought them back and cleaned them out and using the lasagne method planted them up.
OK . How to do that is easy simply use good soil and place some pebbles over the bottom to aid with drainage then put in a layer of soil followed about two inches deep and follow that with a layer of bulbs and then another layer of soil. About four or five layers is good. The secret is to select a variety of bulbs that will flower a at different times of the year following on from each other. Starting in January,February and continuing till around May June time and the top of with some bedding plants for instant colour.
The bulbs that flower last must go on the bottom layer and then going up in successive months of flowering with those that will flower first on the top under the bedding plants.
Do not worry about them being on top,of each other as they will twist and turn to reach the light when they are due to flower . This will give you continuos plants and all you need do is change the bedding plants and remove dead leaves.
Leave them in place and they will return again next year . Just remember to feed them now and again .
