Congratulations! A lot of work has gone into it. Keep watering and feeding, and enjoy it!
Hi - I am not an expert - just a beginner! But I think watering newly planted things is a good idea. From what I have learnt, a watering can full per plant once or twice a week (depending on the weather) is better than a little dribble every day, as this encourages roots to grow deeper. I think putting liquid feed in the water once a week over the summer is also a good idea.
There's no real urgency about feeding, your soil is in good condition and will give your plants what they need. Agree about the watering though, give them a thorough soak when you plant them and then weekly until they're established (more if it's hot and dry).
