Top 5 Summer Flowering Bulbs

Bulbs, tubers, roots and corms will fill your summer garden with an array of colour, depth and variety. What’s more they will continue to do so for many years to come meaning that you can enjoy the gorgeous displays for years on end.

Bulbs are one of the most easiest and rewarding plants to grow and take up very little space in your garden borders so they are ideal for filling in any gaps.


When to Plant Summer Flowering Bulbs

The perfect time to start planting you summer bulb display is usually around mid-March when the weather has started to get a bit warmer. With a little forward planning, magnificent displays can easily be created.

Bulb Planting Depths

For the novice gardener, a key point to consider when planting bulbs is the depth that the bulb needs to be planted. Bulb planting depths can vary depending on the plant species and the size of the bulb. As a rule of thumb, most bulbs can be planted at a depth of approximately 3 times their own height. However, it is advised to check the individual labels for the exact depths before planting.


Display Compositions

When planning your display, consider the heights of the plant once they are in full bloom. Usually, tall-growing bulbs are planted towards the back and in the middle of the flower bed / border and smaller bulbs in front and medium-high ones in between. The benefit of bulbs is that you can personalise your display and make it your own. You may even choose to grow bulbs of all sizes in a single space.

Tall bulbs will need to be planted at a deeper depth, so plant them in first. Then add a layer of soil (Our Bulb planting compost works wonders!) and place medium-high bulbs directly over them. Finally add another layer of soil and then plant the small bulbs. Since small bulbs flower first, the same spot will offer a succession of bloom for the gardening season.
