Good morning and welcome MMflower
That sounds like a fabulous garden - all those trees!!!
I think those plants will be fine - if I were you I'd get some Fish Blood & Bone and sprinkle some around them, as directed on the pack - that's a balanced slow release fertiliser that will promote healthy growth.
And my tip of the day for you is: Walnut trees give off something that stops most other plants growing close to them, so don't waste effort and money planting anything underneath yours.
But on the other hand - I love walnuts - has yours got any nuts forming yet? Watch out for crows and rooks - they steal them!
