Early crocus

How to plant it

General steps for this plant. Save a garden and these become specific to your location, soil and light.

1. Step 1When to plant

   Plant during September to November.

   Bulbs are planted while dormant, a season ahead of the display.

2. Step 2Where to put it

   Choose a position in full sun for most of the day. Allow 0.2 m of room around it — mature spread is 0.1 m and mature height 0.08–0.12 m.

   Light in your garden is not answered, so this is the plant's own requirement.

3. Step 3Preparing the ground

   Dig a hole twice as wide as the root ball and no deeper, loosen the sides, and plant so the top of the root ball is level with the surrounding soil.

   Soil is not answered. This plant grows in free-draining, average conditions.

4. Step 4Watering while it establishes

   Water thoroughly at planting (5–10 litres), then only when the top few centimetres of soil are dry, through the first growing season.

   Even a drought-tolerant plant (4/5 here) only becomes drought-tolerant once established.

5. Step 5Mulch

   Spread 5–7 cm of composted bark or garden compost around the plant, keeping it clear of the stem.

   Mulch cuts water loss and suppresses weeds through the first summer, when losses are most likely.

6. Step 6The first year

   Check it after strong wind and in long dry spells. Little else is needed.

   Maintenance level on the plant record is low.

7. Step 7What to watch for

   Squirrels dig newly planted corms.

Spacing: about 0.2 m apart — roughly 250 plants for every 10 m² if planted as a group.
