Maybe they didn't build up enough root system, you grew them in little seed pots, runners have long roots best grown in root trainers or if you don't want to go to any expense you can use toilet roll tubes or deep polystyrene cups. One in each.
They need to be about twelve inches tall before you harden them off over two weeks, even then it may be cold at nights. They need to be watered when they first go in the ground.
Did you dig a trench and fill it with compost, veg peelings, grass etc.
Lavender cuttings, I can't do those either, but I have a complete packet of seeds germinated. Don't beat yourself up over failures, we all had them when we were learning. You will find the best way to do things.
