Add a cup or two of Ammonia sulfate (or any other acid producing fertilizer) and add some regular fertilizer. Water in good and keep moist. Mulch will help to slow down the loss of water. I like to add acid fertilizer in the fall and spring. Also you can use a liquid acid fertilizer such as Mir-acid. Any pruning should be done right after flowering. |
