Care Guide – March 2021: Summer-Flowering Bulb Collection

Summer bulbs should be planted in spring, when the soil is beginning to warm up and directly after purchase.

Sun or Shade (& Soil Type)

Your bulbs will enjoy a warm, sunny position, in fertile, free-draining soil. Heavy, clay soil can be improved by digging in 1-2 buckets of coarse sand per square metre.

Planting Info

To plant, dig individual holes for each bulb or a trench if you’re planting in groups. Place bulbs in the holes without pushing down hard. Make sure the growing point is pointing upwards, then cover with soil.

Use the bulb as a guide and plant it two or three times its depth. Space them approximately two to three bulb widths apart.

Peter explains how you can plant bulbs in pots using the “lasagne’ planting method !

Flowering Time and Heights of your Bulbs:

Anemone Blanda – Flower May-Jun, Grow to 10cm

Many summer bulbs are ideal for growing in patio containers, especially the more tender species, which can then be stored over winter.

Storing Bulbs Over Winter

If you want to store your bulbs over winter, then lift them before the first frost. Bulbs generally prefer to be stored dry.

Remove loose soil, carefully pull or cut off dead and dying leaves and leave to dry overnight. Dusting with fungicide will help keep the bulbs healthy.

Store the bulbs in dry paper bags or trays of almost dry sand in a frost-free place.
