How to Grow Agapanthus – Description
The Agapanthus is a perennial plant with tuberous roots, so it is not exactly a bulb, although it is usually included among the bulbous plants.
It can reach between 39″ and 59″ (1 meter and 1.5 meters) in height, although nowadays we can find dwarf varieties.
Agapanthus flowers appear at the end of a long, rigid stem. They are dense umbels, which offer 10 to 30 tubular flowers 0.6″ to 1.6″ (1.5 to 4 cm) long.
The clusters closely resemble ornamental onions.
The appearance of the flowers is fleshy and their coloring differs according to the variety, although the most common and popular are the blue and white Agapanthus.

How to Grow Agapanthus Step by Step
The Agapanthus is a plant of great ornamental value, even when not in bloom, but to keep it outdoors the climate should be temperate. With light frosts, the tuberous roots should be protected with a bed of dry leaves, straw, compost…
It could tolerate cold up to 18 °F (-8ºC), but it would lose all its leaves. In these cases the best option is to plant in pots, so you can play with keeping it in a protected place during the winter.
The only “disadvantage” of potting is that the roots tend to cover the whole pot and break it, so it is advisable to change pot every year.
Its planting time is in early spring so that we will have flowers in summer.
If the Agapanthus has been planted for some time, it will flower in late spring.
How To Grow Agapanthus in Gardens
To grow Agapanthus in the garden, follow these tips:
- If you’re wondering when to grow agapanthus, the right planting time is spring.
- The tuberous roots should be planted a few inches above the surface.
- The proper distance from the plant to plant is about 5″ to 24″ (13 to 60 cm).
- They prefer sunny situations but perfectly tolerate and tolerate semi-shade.
How to Care Agapanthus
Agapanthus can be perfectly naturalized in the garden, (as long as we do not have very strong frosts) offering interesting foliage throughout the year, and its spectacular flowering in late spring or early summer.
They are not too demanding plants, but it is convenient to know the best way to grow them.
They are not very demanding bulbous plants, but they prefer rich and fertile soil, as well as good drainage.
If our garden does not offer these conditions, we can always improve fertility by adding compost and/or mature animal manure. For drainage, river sand, pine bark, gravel…always depending on the composition of the soil of our garden.
Remember that in places with light frosts, it is advisable to protect the roots by adding a layer of dry leaves.
Agapanthus prefers sunny locations, where it will offer its best blooms. In very dry climates, it can be placed in semi-shade, where it will also offer very good results.
Agapanthus watering should be abundant during growth and flowering, coinciding with the growing season.
When winter arrives, watering should be reduced and moderate, to keep the foliage until the following season.
The ideal time to fertilize is at the end of winter. It is advisable to add fertilizers with low nitrogen content. For a correct growth of the agapanthus we recommend to fertilize them.

How to Grow Agapanthus – Pests
They are quite resistant to pests, as they produce phytoecdysteroids, compounds that repel most insects that could feed on their leaves. As with garlic or onions, agapanthus extract has antifungal properties (preventing fungal attack). In any case, they can be attacked by snails, but they are easy to avoid if we add wood ashes around them or prepare beer-based traps.
How to Propagate Agapanthus Step by Step
Agapanthus can be easily propagated using its seeds or by dividing its roots at the end of the summer. If we decide to multiply by seeds, we will not cut its flowers, we will let them dry in the bush until we observe (towards the end of the summer) that the pods change from green to brown:
- We will collect the seeds, which we will keep until spring.
- When spring arrives we will place them in trays, with good compost. Sprinkle the tray with the seeds, cover them lightly and water them well, taking care not to lift the seeds.
- When the seedlings are large enough to handle, we will transfer them to pots and let them grow. These plants will take two or three years to flower.
The most common way of propagation is by division of the roots towards the end of summer:
- It is advisable when the plants are very large because they end up leaving little space between each other. This process is done every 4 or 5 years.
- One of its advantages is that, if we make few divisions, we will have flowers the following year without any problem.
- The process is very simple, just lift the roots at the end of the summer, when there are no flowers left.
- Proceed to cut and divide the roots of the plant with a sharp knife. If we make many divisions, it will take longer to flower.
