Ive never grown fruit and veg before and have decided to give it a whirl. Ive acquired some wooden fruit crates from a greengrocers. Ive lined them with heavy duty rubble sacks and this is where you come in, whats next? What type of compost do I use and which veg. From what Ive read, lettuce would be a good start. Am I too late in the year to try anything else? Im v.enthusiastic but on a tight budget hence the free containers. Any help would be great, thanks.
