Read every label before mixing
Different bulbs have different planting requirements and seasonal needs. RHS bulb guidance distinguishes groups and notes that site preferences vary. Keep each named batch separate until you have checked the planting information and its suitability for your climate. Do not convert a general depth rule into an instruction for every species. Write down the cultivar, quantity and intended position before a collection of similar-looking bulbs becomes one anonymous pile on the garden bench.
Test the pattern on the surface
Arrange the groups temporarily where you intend to plant, following the species’ spacing guidance. Stand back at the normal viewing point. Consider whether the group can be seen from indoors, whether it interferes with later work and where future foliage will occupy space. Keep bulbs away from children or animals that might handle or eat them. This surface rehearsal is a design exercise; complete planting promptly under suitable conditions rather than leaving material exposed indefinitely.
Make a map with fixed references
Record the planting positions relative to a path, wall or established plant rather than drawing a mysterious circle on a blank page. Include the planting date and source information. A photograph before backfilling can supplement the sketch if it clearly shows the positions. Keep the map where you plan later additions. Its value becomes obvious when the bulbs are dormant and an apparently empty space begins to look like an ideal place for another vigorous perennial.
