Your Guide to Buying and Planting Seasonal Bulbs
When to Plant Your Bulbs
The timing of your planting dictates the success of your floral display. Spring-flowering bulbs, such as daffodils, tulips, and crocuses, must be planted in the autumn. They require the cold winter soil to break their dormancy and develop strong root systems before flowering. Conversely, summer-flowering varieties like dahlias and gladioli are tender; they should be planted in the spring once the worst of the winter weather and the risk of frost has passed.
Storing Bulbs Before Planting
It is common to purchase bulbs early in the season to secure the best varieties, which means you may need to store them for a few weeks before the ground is ready. To keep them in optimal condition, store your bulbs in a cool, dark, and well-ventilated space. Avoid damp areas, and keep them in breathable paper bags or netting rather than plastic, which can trap moisture and lead to rot.
Frequently Asked Questions
Which way up should I plant a bulb?
As a general rule, plant bulbs with the pointed end facing upwards towards the sky, and the flatter, rougher root end pointing down. If you are unsure, or if the bulb is irregularly shaped like an anemone corm, simply plant it on its side. The shoots are remarkably resilient and will naturally find their way to the surface.
Do I need to soak bulbs before planting?
The vast majority of spring and summer bulbs do not require soaking and can go straight into the ground. However, certain hard, dried corms—such as Anemone blanda—benefit greatly from being soaked in a bowl of water overnight. This helps to rehydrate them and kickstart their growth before planting.
What is the best soil for growing bulbs?
The most important requirement for bulbs is well-drained soil; sitting in cold, waterlogged ground over winter is the primary cause of rot. If your garden has heavy clay soil, improve the drainage by mixing a handful of horticultural grit or coarse sand into the base of the planting hole, and incorporate organic matter to improve the overall soil structure.
