It's Agapanthus Time!

It's Agapanthus Time!

Agapanthus in full bloom are a sign that summer is not far away. Their beautiful colours and shiny green leaves look spectacular in borders and will often be seen along fence-lines, garden beds and bordering drive-ways.

They come in a range of colours including the most commonly seen; purple and a range of pinks and white. They are also available in a range of sizes which you need to take into account when selecting the variety that is most suited to your needs.

How to Plant and Grow Agapanthus
You do need to ensure that you give your agapanthus space. They will form clumps that can be up to a metre across, and you will need to ensure that you thin them out from time to time - if you don't, flowering can be impeded. For the best growing results, follow these planting and growing tips:

  • They transplant well. So when you thin agapanthus out, use the plants to create new gardens, or share them with friends.
  • Plant agapanthus about 50cm - 60cm apart and about 2.5cm deep. Don't be tempted to crowd them; you will be rewarded for this over the next few years.
  • Early spring is the best time to plant - this enables them to provide you with a beautiful showing of flowers in summer.
  • If you live in a cool climate; a full sun position is best. In hotter climates, position them in semi-shade.
  • The soil needs to be well-drained with plenty of organic matter dug throughout. You will probably not need to fertilise, but if you do, only fertilise lightly.

Looking After Your Agapanthus
Agapanthus are very "hardy"plants, but following these tips will help:

  • When newly planted, water regularly and fertilise occasionally (not too much) with seaweed liquid fertiliser. A treatment with Sulphate of Potash mid Spring will help reward you with beautiful flowers a little later.
  • After the first flowering, water much less - depending on your climate, you may even not need to water them at all.
  • Agapanthus spreading can be a real environmental problem, so prune any spent flower heads. Doing this will also look much better as well.
  • Agapanthus rarely affected by pests, but as a part of normal garden maintenance, check them regularly and treat pests/diseases when necessary.
  • Divide root clumps every two to three years in early spring, after the plants have flowered.

Agapanthus as Weeds.
In some areas, agapanthus are considered noxious weeds. The reason for this is because their seeds spread very easily and invade areas where they are not wanted. They can then be very difficult to remove. Therefore, it is very important that spent flowers are removed and not allowed to form seeds.
