Conifers

No. Some conifers periodically replace older inner needles. However, brown outer tips, whole dry branches and a rapidly growing patch need investigation. Check the root ball, moisture, planting depth and possible damage. Photograph changes over several days; do not prescribe fertiliser or treatment solely from needle colour.

Check both the container root ball and surrounding garden soil: they may dry at different rates. Apply water slowly to the roots and make sure it does not run only around the root ball's edges. Adjust frequency to weather and moisture checks. Constant wetness is as undesirable as drying out.

First check whether living green growth will remain below the proposed cut. Many conifers regrow poorly from old bare wood. Maintain the normal shape with moderate trimming of fresh growth. Plan major height or width reduction according to species, cultivar and row condition rather than one severe pass.
