Welcome to my website about growing ornamental plants organically. Few gardens work well without flowering plants, and in an organic garden where insect activity is encouraged, they are vital. My flowering plants bring pleasure by filling the air with wonderful fragrances and stimulate the senses with their beauty............................................John Ashworth 26th December 2015.
Euphorbia characias wulfenii are beautiful plants with strong upright stems topped with lime green flowers (bracts).
The flowering stems need to be cut back to ground level when flowering finishes. This prevents the flowers from going to seed, and encourages the growth of new shoots.
inclined to be invasive making large quantities of seed which set

to see and remove, but keep them under control or they will take over.
Mediterranean plants including Euphorbia Wulfenii grow rapidly in spring
and set flowers before slowing down their metabolism to conserve water
during hot dry weather.
Once the cooler wetter months return, new growth starts and continues right through until the heat of summer returns.
They prefer light well drained soil, and hate getting their root systems water logged in winter.
They are poisonous plants and are rarely attacked by pests. Care needs to be taken handling them.

Minimise soil disturbances to maintain a natural soil structure.
Feed the Soil.
In September, remove old mulch, fallen leaves and other decaying organic material. Dispose of them in the compost heap.
Euphorbias are usually pest and disease free due to the poisonous nature of the plant's tissue and sap.
I spray the foliage with aerated compost tea in spring and autumn, and
feed the soil with a drench of aerated compost extract and a layer of
home made compost, to boost microbial and worm activity.
These measures improve the plants resistance to airborne and soil borne pests and diseases.
