This hardy plant is perfect for beginners, and its showy blooms will add a splash of color to any space. Here are our tips for how to care for Agapanthus so you can enjoy these lovely flowers all season long.

Introduction to agapanthus

The agapanthus is a beautiful, long-lived flowering plant that’s easy to grow in most gardens. With its large, showy flowers, it’s an excellent choice for adding color and interest to your garden.

Agapanthus are native to South Africa and belong to the subfamily Agapanthoideae, which includes several other genera such as Allium (ornamental onions), Eremurus (foxtail lilies), and Hosta (plantain lilies). There are about 10 species of agapanthus, but only one, Agapanthus africanus, is widely cultivated.

Soil and water requirements

Agapanthus need a minimum of four hours of sun per day, although six to eight hours of sun will produce the best results. They are tolerant of a wide range of soils as long as they are well-drained, but prefer a soil with a higher organic content. Sandy soils can be amended with the addition of organic matter prior to planting.

It is important to water agapanthus regularly and deeply, especially during periods of extended drought. They are relatively drought tolerant once they are established, but will flower better with adequate moisture. A 2-inch layer of mulch will help to conserve soil moisture and reduce weed growth.

Fertilizing agapanthus

Fertilize agapanthus in early spring with a slow-release fertilizer, such as an Osmocote or Miracle Gro product. Apply the fertilizer according to package directions.Agapanthus will also benefit from a mid-season fertilizer application in late spring or early summer.

Pruning agapanthus

To keep plants tidy, wait until big clusters of flowers have faded, then cut the whole stem right back to the ground. You could also cut back a third of the plant in early summer and a third in late summer to encourage even more flowers.

Propagating agapanthus

Agapanthus are easy to propagate from seed, cuttings, or divisions of existing plants. If you have a friend with an agapanthus plant, they can easily provide you with information on how to care for your new plants.

To propagate from seed:

1) sow agapanthus seeds in a well-drained potting mix in spring or early summer.

2) cover the pots with clear plastic to maintain humidity and place them in a warm, sunny spot.

3) keep the soil moist but not wet and wait for the seeds to germinate, which can take anywhere from two weeks to two months.

4) once the seedlings have emerged, remove the plastic and water them regularly.

5) transplant the seedlings into larger pots or into the garden once they have grown to about 10cm tall.

Overwintering agapanthus

Agapanthus, commonly known as African lily, is a herbaceous perennial that flowers from late spring to early summer. The plants are evergreen and will flower year after year with little maintenance. Agapanthus is a native of South Africa and does best in full sun or partial shade. The soil should be well drained and the plants should be allowed to dry out between watering.

Pests and diseases of agapanthus

Agapanthus is a robust plant that is generally pest and disease free. However, there are a few problems that can affect the health of your plant, including:

  • Snails and slugs: These pests are attracted to the soft, succulent leaves of agapanthus and can cause significant damage if left unchecked. Handpick snails and slugs from your plants or use a bait such as iron phosphate to control them.
  • Crown rot: This fungal disease can be a problem in areas with humid summers. It is characterized by yellowing leaves, wilting flowers, and blackening of the roots and lower stem. If you suspect your plant has crown rot, remove affected parts of the plant and dispose of them. Destroy infected plants if they are beyond saving.
  • root-knot nematodes: These small creatures live in the soil and feed on plant roots, causing stunted growth and yellowing leaves. If you suspect your plant has root-knot nematodes, contact your local Cooperative Extension office for help in identifying the problem and recommended treatment options.

Using agapanthus in the garden

Agapanthus are dynamic and striking plants that add a unique touch to any garden. Though they are native to Africa, they have become increasingly popular in gardens all over the world. Here are a few tips on how to use agapanthus in your own garden:

  • Agapanthus make excellent borders and edging plants. They can also be used as focal points or accents in larger garden beds.
  • They look particularly striking when planted in mass, such as in a large bed or along a walkway.
  • When planted in pots or containers, agapanthus make great focal points on patios or decks.
  • Agapanthus are also well suited for use in cut flower arrangements.

Agapanthus for containers

Agapanthus for containers is best done in the spring, after the last frost has passed. Choose a well-draining pot, and fill it with a potting mix that is light and airy. A mix of 50% peat moss and 50% perlite or vermiculite works well.

If you are planting more than one agapanthus in a single pot, make sure to space them evenly so that they have enough room to grow. You should also make sure to choose a pot that is large enough to accommodate their roots.

Water your agapanthus regularly, and fertilize them once a month with a water-soluble fertilizer. In the winter, reduce watering but do not let the soil dry out completely.

When choosing a location for your potted agapanthus, make sure to choose an area that gets full sun. Agapanthus also tolerates partial shade, but they will not bloom as well in shadier areas.

Agapanthus species and cultivars

Agapanthus species and cultivars are generally evergreen perennials that range in height from 30 cm to 1.8 m (1 ft to 6 ft). The strap-like leaves are basal or whorled and the flowers borne in clusters, with each flower stalk supporting 1-20 blooms. The sepals and petals are fused together at the base to form a tube. The flowers may be blue, violet, purple, white or pink and bloom in summer.
