Only just got a garden last year. In the past I would congratulate myself if I kept a cacti alive...
We've got a long stone bed about 1m wide by the fence that runs the length of the garden. It was overgrown when we moved it with weeds and rubble. We've cleared and sieved over the summer, put fabric down and planted some basic bits like lavender, a couple of types of spreaders, some tall (40-50cm) Spring flowering flowers that I can't remember the name of and left a little patch and popped a bee friendly mix in there and the rest currently has bark chips on as there's quite a bit of space left in between the plants and we wanted to avoid the mass of weeds that tend to appear overnight in the soil here.
To be honest I haven't done anything to it since probably September 
Currently WFH and will be for the foreseeable and I'm hoping to make a good early start on the garden this year.
Could anyone give me some basic tips on when I should get in there to clean up and do some more planting?
I'm hoping to grow some more colourful flowers and easy to maintain perennials and also would love a climber - could anyone suggest some good ones?
We are in the countryside and I think it's clay soil and a south east facing garden. The beds get direct sunlight up until about 12 in the summertime.
