What Is Meant By Planting Bulbs ‘In The Green’?


Plant snowdrops, English bluebells and aconites just after flowering

Some bulbs, when planted dry, do not have a very good success rate. Planting them just after they have finished flowering, when they still have leaves, ensures an almost 100% success rate. They are usually sold either flowering planted in a pot or as bundles wrapped in paper; if they arrive wrapped in plastic take them out as soon as possible as they can rot. The potted bulbs can be planted at any-time as long as they are still ‘in the green’; the bundles, which won’t be in soil, need to be planted as soon as they have arrived, so make sure you have somewhere planned for them.

When they arrive in a bundle just gently tease them apart taking care not to damage the roots. Plant them to the depth they were originally; you can see where this is from the colour of the stem. The plants will benefit from the addition of compost or leaf mold to the planting hole & soil, if you are concerned about rot, add some coarse sand around the bulb area to improve drainage. If you already have clumps of these bulbs and they are producing fewer and fewer flowers carefully dig up the clump, separate the bulbs and re-plant.

The main bulbs planted ‘in the green’ are Winter Aconites, Snowdrops and English Bluebells.

Daughter of a farmer and market gardener so have always had a connection with the outdoors, whether it was keeping animals or producing fruit, vegetables and cut flowers. Along with my work at Hayes Garden World I also have a smallholding, mainly breeding rare breed pigs. I gained an HND and BSc in Conservation and Environmental Land Management, as a result I am an ardent environmentalist and have a keen interest in environmentally friendly gardening. In my time at Hayes I worked for several years in the Outdoor Plant and Houseplant areas.
