How to Plant Agapanthas


Most gardeners choose agapanthus (commonly misspelled "agapanthas") because of its impressive height and brilliant blue flowers. However, agapanthus' full potential can only be realized when it is grown in USDA growing zones 7 and above. When in the right climate, and planted in full sun, agapanthus can essentially be planted and forgotten. This African beauty is perfectly capable of taking care of itself even if you forget to water or fertilize it year after year.

Step 1

Dig holes for your agapanthus bulbs. These holes should be deep enough to allow 3 inches of soil to cover the bulbs. Allow 6 inches of space between neighboring holes.

Step 2

Plant two to three agapanthus bulbs per hole. Agapanthus roots like to be crowded and planting them this way will force the plant to flower next spring. The bulbs can be planted individually, but it may take them 3-4 years to flower.

Step 3

Spread a 3-inch layer of compost around, but not on top of, your freshly planted agapanthus.

Step 4

Water the bulbs enough to soak the soil. Continue to keep the soil moist for the few weeks that it will take for your agapanthus to germinate. Once the plant is established, water it sparingly, only when the top 3 inches of the soil are dry.
