Autumn: Time to Plant Spring Flowering Bulbs

Check what spring bulbs are available

The choice of bulbs now is larger than ever before and includes both the exotic and indigenous bulbs. Most of the exotic (non-indigenous) bulbs grow wild in various parts of the northern hemisphere and include Daffodil, Hyacinth, Ranunculus, Snowflakes, Dutch Iris, Anemone and Brodiaea.

Even more exciting is the wide range of indigenous spring flowering bulbs (including their hybrids and cultivars) which are now available. Most are native to the winter rainfall areas and include the old favourites such as Freesia, Sparaxis, Tritonia, Babiana and Lachenalia.

Growers of indigenous bulbs have produced a host of new varieties of bulbous plants over the past few years, and among the new range of dry bulbs are new varieties of the colourful Wand Flower (Ixia species), Ornithogalum 'Namib Sunrise', Watsonia, and Cyrtanthus 'Sunshine'. Also look out for potted Bush Lily (Velheimia bracteata), Wild Tulip (Homeria elegans) or Wild Gladiolus (Gladiolus tristis).

By far the most interesting new arrivals are the new hybrid March Lilies (Amaryllis belladonna). Available as dry bulbs, they are best planted in autumn and are likely to flower just once, late in the first summer. Although March Lilies resent being moved, once settled, the new selected cultivars will flower twice (in spring and again in late summer) from the second year.

Success with Spring Bulbs

Bulbous plants are easy to grow provided the instructions on the packs are followed carefully. Take particular note of whether your chosen bulbs prefer full sun or partial shade, and choose the correct spot in the border. Most bulbs prefer a position where they get morning sun and some afternoon shade rather than where they receive full afternoon sun.

Consider these tips when planting spring bulbs

• Bulbs flourish in a rich garden soil that has sufficient drainage, so add plenty of compost to the soil before planting.
• Water the soil before planting and plant as per instructions.
• Note carefully how deep the particular bulb variety must be planted in the soil. If you plant them too deeply they will not sprout. If you plant them too shallowly the plant will fall over because the roots will not be capable of supporting the leaves.
• If you want maximum flowering effect, plant your bulbs very close together.
• Keep the bulbs thoroughly watered throughout the winter growing period. Remember that the plants should be kept moist but not water-logged. Water the bulbs every four days when they are in flower.

Planting Bulbs in Containers

Bulbs can also be planted in containers on the patio. Make sure that the container drains well by placing broken pot pieces or large stones at the bottom of the container before filling with a light potting soil.

Position the containers away from any draughts or windy areas. Water the soil regularly to ensure it remains moist at all times, but avoid water-logging.

When the bulbs in your containers are in full bloom, you can move the pots indoors. Position them so that the plants receive as much of the winter sun as possible. As soon as the plants look unhappy move them outdoors again.
