Most Agapanthus species are usually hardy in USDA zones 8 to 11. Still, their tolerance to frost and cold can vary from one variety to another. Because of this, it is very important to choose the most suitable variety for you depending on the average temperatures and also the region you live in. Once you do this, you can overwinter your plants with no problems in the future.
Although African lilies are resistant to most pests and diseases, sometimes things will not go according to plan. The most common disturbers of these plants include powdery mildew, anthracnose, grey mould, and leaf spot. They are fungal diseases that appear mostly in shady, cool, or humid environments and can affect either the foliage or roots of your plants.
If you notice some suspect changes in these areas, remove the unhealthy parts of your African lilies using sterilized pruning shears. In case of severe infections, you may need to apply a suitable fungicide to prevent any possible spread and also the death of your plants.
For optimal growth, plant your young Agapanthus species in spring once the last danger of frost has passed. If you want to grow them in the garden, make sure the soil temperature is at least 50 °F (10 °C). Moreover, you should plant these flowers 12 to 18 inches (30-45 cm) apart to promote good air circulation and avoid over-crowding.
When it comes to the growing medium, African lilies do well in peat-based soil that is rich in nutrients and organic matter. These plants are susceptible to root rot, so you should look for a substrate that has great drainage. For indoor settings, we recommend you plant them in containers that have drainage holes at the bottom to avoid waterlogging.
Your Agapanthus plants will grow nicely with regular fertilizing and will also produce more flowers along the way. Feed these buddies with a balanced liquid fertilizer during their active growing season, the first time in early spring and again two months later. Avoid fertilizers that are high in nitrogen and provide your plants with products that are higher in phosphorus.
Deadheading your Agapanthus plants is mandatory for continuous and profuse blooming. When you notice faded flowers, remove them to make room for new, healthy ones to flourish. This process will also prevent your ornamentals from wasting too much energy on seed production.
African lilies grow at a pretty fast pace, so they need regular repotting if you grow them in containers. In general, you should repot these plants once every 4 years in pots that are slightly larger than the current ones. Yet, if your flowers seem crowded, you can divide them in spring and transplant the babies into other pots without stressing the mother plants.
The only period when you will have to pay some attention to Agapanthus plants is during their active growing season. In spring, water these flowers regularly to maintain their soil damp. Make sure you always check the soil in-between waterings and provide with water only when the top 2 inches (5 cm) of soil feels dry to the touch.
Once their blooming period has ended, you can water them less often or skip their watering routine for good. African lilies typically go dormant from late autumn through late winter. During this period, their foliage turns yellow, withers, and dies back. This is a common sign that you should postpone watering until their next growing season, usually in early spring.
If you want to fill your garden with more Agapanthus plants or just gift some of them to your family or friends, propagation is a great option! No matter how much experience you have in the gardening world, you will find it easy to successfully make more of these buddies in only a few steps. The easiest and most efficient way to propagate your plants is using division.
This particular method is also a nice choice if you grow your African lilies indoors in containers. And why is that? Well, as mentioned above, these plants require regular repotting because they grow and spread like crazy. But, if you divide your flowers once every 4 years or so, you can forget about repotting for a long time and have even more African lilies around!
First things first, you must dig out one or more clumps of Agapanthus plants in early or mid-spring. Once you have the clumps out of the soil, divide their roots with a sharp garden knife. Make sure that each divided part has at least one stem attached to ensure proper future growth.
Once you’ve completed these steps, you can plant your Agapanthus divisions in their permanent locations. Provide the baby plants with a nice and deep soaking to help them settle in their new environment. If you want to grow them indoors, keep the containers in a well-lit and warm spot.
Your garden is incomplete without at least one Agapanthus species in it. Whether you already have one lovely specimen or you think about giving one a chance, there is always room for more plants. And when they are so stunning and easy-going, you cannot stop but simply falling in love with their charming nature!
