Tulips are a highly decorative and desirable bulbs for gardeners and do well in most cool climate gardens. A number of nurseries in Australia and around the world grow and sell an amazing range of Tulip bulbs that come in a range of colours and shapes that can brighten any garden design.
Tulip bulbs internationally can be found from many nurseries around the world. In the United States a very respected nursery for buying Tulip bulbs is Nature Hills Nursery, and a number of their Tulip hybrid range can be seen below –
Family Name: Liliaceae
Botanical Name: Tulipa
Plant type: Bulb
Size: 20-60cm high x 15cm wide
Planting width: 15cm
Planting time: Plant in cool weather (late April or May).
Positioning: Full sun position, but can be grown in a position that receives at least half a day full sun.
General information: Suitable for temperate/dry and Mediterranean climates. Require winter chilling in warm climates. (See instructions on chilling below).
Watering: Tulips like to be kept cool and moist but not too wet. After planting, water well, and once leaves appear they should be given a good watering every 7-10 days depending on how dry the weather is. During dry times of the year, be sure to water regularly, especially after the buds have appeared.
Fertilising: Prepare the soil with a complete organic fertiliser before planting and then use a liquid fertiliser once the buds have appeared and then again after the flowers have faded.
Soil: Well-drained soil, high in organic matter.
Lifting & storage: Should be lifted each year. Dig after the foliage has turned yellow. Allow the bulbs to dry out, out of the sun, and then store them in a cool, dry and airy position.
Pests: Aphids can be controlled by regular rinsing and insecticide.
Chilling Tulips: Purchase your bulbs by the end of March if possible. This allows sufficient time for a cooling treatment in the refrigerator. Chilling your bulbs for 4-6 weeks in the crisper of the refrigerator (not freezer) prior to planting will ensure the longest possible flower stems. Keep bulbs away from fruit and vegetables as the ethylene gas given off by them when ripening is detrimental to the bulbs.
Cold areas will not require as many weeks chilling. If you don't get your bulbs till late in autumn, still refrigerate them for a few weeks, always leaving planting until the third or fourth week in May.
Tips: Double, Darwin and Triumph Tulips flower earlier than Single Late and Parrot varieties, so to keep Tulips in bloom throughout the season plant a mixture of early and late flowering varieties.
If using as cut flowers choose blooms that are not fully open, cut them early in the morning and change vase water frequently. They like some protection from the wind.
Allow foliage to die down naturally after flowering for better flowering the following year.
