My vegetable bed has had compost added every spring for years. The soil is dark, drains reasonably well and grows healthy plants, yet I still follow the old habit of adding another thick layer because garden advice says ‘more organic matter.’ Is there a point where that stops helping or creates nutrient imbalance? I'm thinking of a soil test before adding much more. What signs tell you an established bed needs compost rather than just mulch and careful watering?

A soil test sounds sensible to me. It can tell you whether you’re actually low on something or just assuming the bed always needs another layer because that’s the ritual.
I’d watch plant vigor, too, but not as proof that more compost is needed. Sometimes good growth just means the bed is already balanced enough.

I used to add compost every year until I realized I was mostly making more work for myself. Now I compost less often and mulch more, and the beds don’t complain.

Exactly. Compost is helpful when the soil needs rebuilding, but once a bed is doing well, the question becomes whether you’re improving it or just feeding your habit.
