I really enjoy gardening but I am one of those fearful amateurs. I know that if a plant is not right for its aspect in the garden and it doesn't flourish, just learn from it. Our new home has lots of potential, do I'm slowly working on it. It is also so positive for my mental health.
Tips and advice would be really welcome folks 
I only know about growing fruit / veg but for those it is highly beneficial to use varieties that are known to work well in your area. Do some research on the variety and how to look after it and you should be good.
If starting from seeds a heated propagator is an amazing tool that gives fast and reliable germination.
Once they germinate it is beneficial to give them as much light as possible to stop them stretching too much.
Start them in tiny pots is my method to save tricky early transplanting.
Re-pot them when you see roots coming out of the bottom.
Keep slugs and pests away, they love young plants and will eat them in no time.
Start feeding them when they are bigger at recommended dose.
I could go on and on all day but its probably best to buy some books as mentioned already and slowly start to learn.
