Tulip bulbs are autumn-planted bulbs, ready to flower the following spring. The usual planting window in the UK is October to November, when temperatures are cooler but the soil is still workable. If you have bought tulip bulbs before then, keep them somewhere cool, dry and well ventilated until planting time. Avoid planting into frozen or waterlogged ground, as this can affect growth. Tulip bulbs planted at the right time will establish over winter before producing their spring flowers.

Tulip bulbs can fail to grow or flower for a few common reasons. The biggest is wet soil or compost, which can cause bulbs to rot before they have a chance to establish. Planting too shallowly, planting very late, damage before planting and growing bulbs in deep shade can also affect the result. For the best chance of success, plant firm bulbs in a sunny, free-draining position, with the pointed end upwards. After flowering, leave the foliage until it turns yellow naturally so the bulb can build energy for next year.

Yes, tulip bulbs can still grow if their papery outer skin is dry, loose or slightly flaky. This is normal, especially after bulbs have been stored or handled. Size can also vary, so a bulb that looks smaller than expected is not automatically poor quality. The important thing is that each bulb feels firm and solid, rather than soft, hollow or wet. Plant tulip bulbs as soon as possible after delivery and store them in a cool, dry place until then.

A light earthy smell is normal for tulip bulbs, but a strong sour, musty or rotten smell is not. Check the bulb carefully if it has an unpleasant smell, feels soft or shows wet patches, heavy mould or signs of decay. Healthy tulip bulbs should be firm, dry to the touch and free from serious damage. Do not plant bulbs that are soft or rotting, as they are unlikely to grow and can affect nearby bulbs in the same pot or border.

Tulip bulbs should produce flowers in the colour and form described on the product page. However, natural flowers can show slight changes in shade depending on sunlight, temperature, soil conditions and how open the bloom is. Product photographs are intended to show the expected flower, but they may appear brighter or darker on different screens. Planting tulip bulbs in a sunny position with good drainage will help produce healthy stems, clear colour and the best possible spring display.
