Autumn in the garden means bulb planting! Bulbs are surprisingly easy to grow and with a bit of TLC will reward you with a spectacular show of spring colour. Follow our step-by-step guide to planting bulbs.

 

Keep your bulbs cool

  • Bulbs like to be planted in cool soil. If the weather isn’t cool enough (between 13 and 23 degrees Celsius), store your bulbs in your fridge’s crisper section, in an egg carton or paper bag. Don’t store your bulbs in plastic (they will sweat and rot) and don’t put your bulbs in the crisper with fruit. The gases released by the fruit will ruin your bulbs, and make sure no one mistakes them for onions or your next batch of spaghetti bolognaise could be lethal.

Flower Power tip: Regardless of the weather, tulips, hyacinth and daffodils need refrigeration, but for no longer than six weeks. This tip also applies to bulbs that you have dug out (after they’ve finished flowering and foliage has died off). Just make sure to dry the bulbs out first.

 

Find a spot to plant your bulbs

  • The great thing about bulbs is they’re happy almost anywhere, provided they get full or part sun. If in doubt, read the bulb packet instructions.
  • Planting bulbs in a pot gives you the chance to bring them indoors once in flower.

Flower Power tip: If space is at a premium, plant a handful of hyacinths in a shallow bowl for a compact but glorious display.

 

Preparing soil for planting

  • If planting in the ground, prepare your soil by clearing weeds and rocks, then dig the soil over until it’s fine and crumbly, to at least the depth of your spade.
  • Free-draining soil is a must, as soggy bulbs will rot. Whether planting in the ground or in a pot, a good quality bulb growing mix added to the soil will improve drainage.

Flower Power tip: For a soil boost, dig in a couple of shovelfuls of aged cow or chook manure or compost per square metre.

 

How to plant bulbs

  • Planting depth depends on the bulb, so check bulb packet instructions. A handy rule of thumb is to plant bulbs at a depth equal to twice their width. Bulbs planted too deeply will run out of energy before they reach the surface. Bulbs planted too shallow may be uprooted by birds.
  • Space bulbs at least twice the bulb’s own width apart.
  • Most bulbs are planted pointy end up (growing tip). The exceptions are anemones and ranunculus which should be planted point down, as their point is the root.

Flower Power tip: Don’t forget to mark the spot where you’ve planted your bulbs.

 

Watering your bulbs

  • After planting, water in your bulbs well, then water regularly to keep the soil moist, but not wet.
  • Water deeply again when shoots appear.

 

Mulching and feeding

  • Spread a 25mm layer of organic mulch to keep your bulbs cool.
  • Bulbs come prepacked with beauty and life, cleverly storing their own nutrients but you can help them along. As foliage pops up through the soil, apply liquid fertiliser every two weeks. After flowering, feed bulbs with a controlled-release fertiliser.
