Calla Lily Growing Guide

Calla, also known as Zantedeschia, are a lovely South African Native - they are super easy to grow, and are fantastic at adding colour and elegance to gardens, patios, and vases (Callas are they perfect cutflower - lasting for weeks in a vase!)

New Zealand led the way in the breeding of Callas - many of the worlds best Calla varieties originated from little ol' NZ! Here at the Bulbs Direct Farm, we grow in excess of 200 different Calla varieties (many of which are yet to be released)

Ideally, Calla Bulbs should be planted from September through to around December (if planting into the garden) - it's possible to plant earlier if potted up in a nice warm sunny spot.

Planting your Calla Lily Bulbs:

  • Callas like semi-shade to full sun, so hunt out that perfect sunny spot where all can see! As with most Bulbs, your soil needs to be relatively free draining.
  • Calla Bulbs should be planted to a depth of 5-10cm, and at least 10 cm apart in free draining soil. It's important to loosen the soil to a depth of around 20cm.
  • We recommend sprinkling a handful of general purpose fertilizer, or our special Bulb Fert after planting to really pamper those blooms!
  • A layer of Sawdust or mulch over the top wouldn't go a-miss - this will keep the weeds suppressed, as well as helping to keep the soil temperature constant.

These beautiful bulbs will flower this summer, and will look spectacular.

If we suddenly get a cold snap, flowering may be reduced, but don't panic... next year they'll be back in full force!

Watering is always a must with bulbs - a nice deep watering once planted, and then every week or so thereafter will be plenty.
