Adding compost is always good along with worm castings and Sul-Po-Mag- a blend of sulphur, magnesium, and potash. If your soil is compacted, add gypsum. Apply the fertlizers first, water well, then mulch around the plant with 3" of compost and leaf mulch if available. Don't pile mulch around the center stem , go our 6".
If the area is bare, add compost and worm castings then consider planting a cover crop that helps fix nutrients and keeps the soil loose & friable. Seeds are availble for oats, buckwheat, peas, and barley.
