I am a complete garden idiot. Absolutely NO Idea. For example, dd wanted to plant tomatoes; I bought a tomatoe plant from aldi (which we frequently forget to water). THAT kind of bad 
Anyway! We have a huge garden (with a tiny house) and I am massively conscious of the fact that summer is flying past and I havnt done anything in the garden for the dd's. I just don't know where to start. It has trees all around it and er, flower beds (?) at the bottom. 
There is a shed in one corner. Apart from that, it's all lawn and lots of space.
How could I create a lovely place for the dd's that they could maybe even use all year round . I saw some lovely butterfly solar lights on the Argos app last night which I've reserved , could throw them up somewhere.. I'm open to all ideas! Dd's are 5 and 1.5. Dd(5) adores plants/growing things but also likes her swings and park things. Some seating area would be nice, somewhere. It's just so big compared to our previous garden, I don't have a clue where to start.
