Knowing when to plant bulbs is half the magic

There is a particular kind of satisfaction in getting bulbs into the ground at just the right moment. You press a papery, unremarkable thing into cold soil, walk away, and months later it answers you with colour. Knowing when to plant bulbs is what turns that gamble into a near certainty. Plant at the right time and the roots settle, the cold does its quiet work underground, and spring arrives exactly as you hoped. Plant at the wrong time and even the best bulb sulks. Timing really is most of the job.

This tool exists to take the guesswork out of it. Pick a bulb, tell it roughly what month it is, and you will see the ideal UK planting window, how deep to plant, how far apart to space each one, and when you can expect the first flowers. The calendar strip shows planting time and flowering time side by side across all twelve months, so you can see at a glance whether you are early, late, or right on cue.

From spring bulbs to summer bulbs, every season has its moment

Most people think of bulbs as an autumn job, and for good reason. That is the season for spring bulbs, the daffodils, crocus, alliums and hyacinths that carry a garden out of winter. Knowing when to plant daffodil bulbs or when to plant tulip bulbs matters more than almost anything else you do with them: daffodils want to go in early, while tulips prefer to wait until the colder soil of late autumn. Get those two right and you have the backbone of a spring garden.

Then there are the summer bulbs, the ones that reward a little patience through the colder months. Dahlias, gladioli, lilies and begonias go in during spring for flowers that carry the borders from June deep into autumn. There are autumn bulbs too, like nerines and colchicums that flower when everything else is fading, and winter bulbs such as snowdrops and aconites that push up through frost. Whatever the season, there are always bulbs to plant now, and there is always something to look forward to.

Depth, spacing and the little details that make the difference

Timing gets you most of the way, but a few details decide whether a bulb merely survives or truly thrives. Planting depth is the classic one, which is why so many people search for how deep to plant daffodil bulbs or how deep tulip bulbs should really go. As a rule, most bulbs want a hole two to three times their own height, though there are notable exceptions the tool will flag for you. Whether you are planting bulbs in pots by the door or drifting them through a border, the same care applies: right depth, right spacing, right time.

Bulbs are one of the most generous things you can plant. A small amount of effort now, at the correct moment, pays you back for years as clumps thicken and spread. Use the timer above whenever you are wondering what to plant, get the timing right, and let the garden do the rest.
