| Maintenance | I like to dig a large hole, not to deep and mix the soil with 50% peat moss or compost. Plant in a slight mound for good drainage. Add a cup or two of Ammonia sulfate (or an other acid producing fertilizer)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. |
