I feed mine all year round. As @Lyn says, they tend to be a bit thinner on the ground at the end of summer when there's lots of "natural" food around for them.
The only change I make is to stop dried mealworms in food as if its given to nestlings they can choke or become dehydrated as they have no access to water. So none between March and August.
I also feed all year around, although I tend not to give fat balls/cakes etc in the heat of the summer when they heat up/melt and disappear far too quickly. I don't think the birds need the extra fat in the summer. However I do continue with the seeds and various grains etc. all year.
Never stop feeding, enjoy seeing the birds in the garden, feed sunflower hearts in feeders mixed seed on the paved area below the feeders, fats during the winter in a feeder.
Birds have stopped coming to my feeders since I cut back the buddleia adjacent to the feeding pole. Should I leave it where it is or move it to an area nearer shrubs? I can’t believe I was stupid enough to cut it back and risk upsetting my little feathered friends!
I wouldn't worry Debs. They will come back. They are quite sensitive to even the slightest of changes in their feeding places. When I bought new seed feeders with different perches (a small platform style rather than just the rod style), it was about a fortnight until they plucked up the courage to come in and try them.

... we also provide live mealworms for the robins when they’re feeding nestlings. They take them from our hand.

March and August.
Surprised to read the odd post saying the opposite considering how busy a time of year it's about to be for the birds.
