Provide organically rich, acidic, well-drained soil with a thick layer of mulch to keep roots cool, avoiding the crown. Protect from harsh afternoon sun. Water deeply, regularly in first growing season to establish an extensive root system; once established, prefers evenly moist but not soggy soil. Apply an acid fertilizer after bloom.
