ooooh exciting!!! I was never into gardening, but have been learning over the last few years and absolutley love it now. I'm no way an expert but have done some veggies the last few years, and some flowers from seed. My first step, once weeds are gone, would be to plant your bulbs and maybe get some perenials in. They come back year on year, so are a good investment. If you want to have some lovely flowers you can cut and bring inside, sweetpeas are fantastic and super easy. You'd want to get them planted in pots now, and they need some support when planted out (you can just make a wigwam out of bamboo canes and use that), and they produce loads of gorgeous fragrant flowers. As long as you cut the flowers off, they just keep producing more.
Strawberries are super easy. Don't fruit much in the first year, but a few plants will send out runners and you can pot them up, and end up with loads of new plants for subsequent years. They grow well in pots too. Think about what you like to eat. Courgette are really easy and one plant gives you loads of them. Also we grow lots of tomatoes - super easy, and they taste amazing! Most do need support, but it's easy to make a bamboo cane wigwam thing, and they also do well in pots. Runner beans are also soooo easy, and fast growing, and have gorgeous orange flowers. If you like blueberries, a lot of supermarkets will be getting the plants in cheaply soon. Our local morrisons have them for £2 at the moment. They grow best in pots, with acidic compost (ericacous), and you need a few plants to pollinate each other. Sounds a bit confusing, but honestly, so easy. Just get say three pots, bung the compost in, plant a bush in each, and let them establish. You won't get much for the first year or so, but then should get plenty (i'm hoping, we got ours in last year)
I find youtube great for tutorials on how to grow things. For fruit and veg i really like this channel www.youtube.com/channel/UC9r61qohBg1qgGty4_WzojA
There are some great facebook groups too. General gardening ones, and also allotment ones if you're wanting to grow more fruit and veggies.
If you've got the room, you could get some fruit trees. You can get dwarf patio ones nowadays as well, which don't grow too big if space is limited.
Good luck! It really is such a wonderful thing, planting seeds, getting muddy, watching them grow into lovely plants :) Enjoy
