Once you know the secrets to bulb growing success, you`ll know that bulbs are really quite simple. In fact, most of the bulb growing secrets are logical because in many ways they are like humans in that they want food, sunlight and room to grow. They’re also like us in that they don’t like to sit in pools of water for too long and yet rapidly deteriorate if allowed to dehydrate.

Plant the right bulbs for your climate

Unlike us, bulbs are much more limited in the climates in which they will grow. Most Spring flowering bulbs are easiest to grow in the cooler to temperate climates of Australia but, with a little extra attention, many can be coaxed into flowering in the subtropical climates also.

Plant between March and mid-May

Avoid the temptation to plant bulbs in January and February because at this time of year, the soil can still get very warm, and your bulbs are in danger of being “cooked“, the result of which can be very short flower stems. We recommend that you defer planting until between March and mid-May.

Choose a site with free-draining soil

Spring bulbs require a free-draining soil. In soggy soils, bulbs are prone to rotting. If necessary, soil drainage can be improved by `mounding up` the garden beds with extra topsoil by at least 3 or 4 inches.

Ensure full sun to light shade

Spring bulbs require full sun to light shade only. If your bulbs have long, soft, floppy stems, this is usually a sign that the bulbs are planted in too much shade, which causes the stems to keep stretching as they search for the sunlight they need. Daffodils, Hyacinths, Grape Hyacinths and Cuban Lilies are amongst those bulbs that can tolerate more shade than most.

Give them room to grow

For best results, bulbs need to be planted at the correct depth & spacing. A good rule of thumb is that the holes should be twice as deep as the bulb is high and the same distance apart. The pointed end of the bulb should be upwards. (Anemone & Ranunculi are the only exceptions). If your bulbs are planted too closely together, flowering will be reduced, as each bulb cannot find enough food & water to flower. It's also important to plant bulbs deeply enough so that the surrounding soil supports the stems.

Water well when growing and dry them out when dormant

The secret to watering bulbs effectively is to keep them moist whilst they're growing and dry whilst they're dormant. This rather complex-sounding requirement is actually very easy to satisfy. You simply start watering when the green shoots appear above the ground & start withholding water once the foliage begins to turn brown after flowering. Even if you live in a climate with high Summer rainfall (or you frequently water the garden beds over Summer), you can accommodate this bulb's needs by digging the bulbs up once dormant and storing them somewhere dry until planting time again the following year.

Food, glorious food!

Just like us, bulbs flourish when fed well. A general rule of thumb is to top-dress all bulbs in Autumn (or upon planting) & water them in. Use a specialty bulb fertiliser or general fertiliser. For even better results, a second dressing can be applied once the flowers have faded.

After flowering care

After flowering, it's important to continue watering your bulbs until the foliage dies back completely, because it's during this time that the leaves are collecting energy (they act a little like solar panels) that the bulb stores and uses the following year to produce beautiful blooms for you once again.

Now that you know all the Spring bulb basics, you can grow them with a great deal of success. So please give them a go and see how rewarding bulbs can be.
