How to naturalise bulbs
This method works equally well in borders as in lawns and wildflower areas:
- When planting bulbs for naturalising, scatter them randomly over the chosen area and plant them where they fall. As these bulbs will be in place for several years, check that the bulbs are not very close to each other as overcrowding will reduce flowering.
- Dig planting holes with a trowel or, in grassed areas, use a bulb planter. The holes need to be about three times the depth of the bulb, as shallow planting tends to weaken the bulbs because they are more prone to drying out.
- Break up some of the soil from the plug of turf removed with the bulb planter, and use this to backfill around the bulb once it is in the hole.
- Replace the turf on the top of the hole. Aim to make the top of the turf plug level with the surrounding lawn surface.
When planting small bulbs, such as crocuses, in areas of grass, lift or roll back sections of turf. Fork over the soil and add a little balanced fertiliser, such as Growmore. If possible, score the underside of the turf with a hand fork to loosen the soil before replacing it. Firm the turf by hand or by gently tamping with the back of a rake.
