As a rough guide the plants need at least 4 "true" leaves (not the first 2 leaves) and be sturdy, and it must be past the last risk of frost. You can put them out a bit earlier if you cover them with something (the ends of soda bottles work well and keep the pest off)
ETA can you get seed tape? Its paper with the seeds already in it, you just unroll it in a trench and cover it. We can get spring onions, beetroot, carrot in them and they work quite well straight in the ground. Or grow in lengths of gutter and slide the whole lot into the trench when you're ready to plant out
I've been bitten by the gardening bug. I've never grown a plant in my life and then my son got accepted at a new environmental high school and I have become obssessed! It started with a topsy turvy tomato plant and I loved the taste. Now I am growing potted tomoates, watermelon, peppers, oregano, parsley, corn, cantelope, carrots and beans! I started all of them in these little cardboard planters that you put right into the ground when they have started growing. The watermelon looks like it has the best potential has it has spread and has tons of flowers on it!!!
If anyone is thinking about growning raspberries, I say, "Try it!" They don't require fertilizer OR pesticides.

Thanks! I'm thinking about this....hmmmm. I will have to do some research though. I know absolutely nothing about raspberries, but I may just have to try this.
Starting seeds indoors is really easy and fun. It require the same basic conditions as those started outside. The more important thing after planting seeds in indoor is taking care of it.
