Preparing the soil correctly is very important

Most bulbs like plenty of organic matter so dig in some compost before you plant, especially if you have clay soil. Good drainage is essential otherwise the bulbs will rot so make sure you choose a site with good drainage or add sand or grit to the soil.

Where to plant your bulbs

The colourful spring-flowering bulbs can be planted anywhere in your garden, in sun and shade, in borders and terraces, around fences and trees. Some bulbs, such as daffodils, are at there their best when scattered at random giving a natural look. Avoid planting very close to buildings or directly underneath overhanging branches where the bulbs will receive little or no rainwater.

When to plant

It really is best to plant bulbs as soon as you buy them. If you can’t, open the bags to allow air to get at them, place them in a cool, well-ventilated area where the temperature is about 60 degrees F.

As a general rule, you can plant spring flowering bulbs any time until frost hardens the ground. Daffodils should be among the first to be planted to get the best results. Other bulbs need not be planted until summer and autumn-flowering bedding plants have finished their display. In mild or warm areas, later planting is possible and can be delayed until December.

Judging quality

You can judge the quality of bulbs when you buy them. In the first place, bulb size is very important. As a rule, the largest bulbs will also provide the largest flowers in the spring. Remember that the flower is already stored in these bulbs. For tulips bulb size of 12cm plus (the circumference of the bulbs in centimetres) will give the best results. Daffodil bulbs have several shoots and usually give one flower per shoot.

For some small wild tulips, 6/7cm is a quite suitable bulb size as the wild tulip is the most original form. With hyacinths, a larger bulb will not only produce a bigger plant but also many florets on each raceme. Usual bulb sizes of hyacinths are 15cm and larger.

What depth to plant your bulbs

As to planting depth, a rule-of-thumb is to plant bulbs twice as deep as the bulb is high. If you want another easy rule to remember: plant the base of the bulbs, (the flat side) at a depth of 20cm for larger bulbs and 10cm for smaller bulbs such as anemone, scilla, muscari, snowdrop etc.
