1st time grower

Tall trees

This is my 1st attempt at sweet peas not sure if I’m doing right, they dont have many flowers and some of the young leaves are curling up, I feed them and pick flowers when they appear, do I need to do more?

They look ok/healthy to me. When did you sow them? (And where are you, roughly.) They may have just not got going properly yet.
Maybe someone else can comment on the leaves curling up.

Sweet peas need a lot of water, and hearty soil. A slow release food when planted, plus good soil, will keep them going until they've been flowering for a while. Later in the season, a regular feed of tomato food or similar will keep them going.  The more you have in a small space, the bigger the  drain on nutrients and water too.  
However, if they're in a raised bed like that, it drains more quickly, so make sure they aren't short of water. That's very important. Once they get a good amount of foliage, rainwater doesn't penetrate so well either, so just check regularly, even if you have some rainfall.
Other than that, they look fine. they don't all start flowering at the same time.

They need lots of water, so for that many I would say a couple of watering cans every other day, unless it's hot 25° ish then a can a day. It's early yet so will get into flowering soon.😁

Thanks, I water every day and living in Wales we get plenty of rain, plus I’ve mulched that’s what makes me think why is the leaves curling, I’ll up the watering.
