Euphorbia griffithii - the Griffith's spurge - is a species of native to Bhutan, Tibet and south west China. It is a spreading herbaceous perennial growing to 90 cm (35 in) tall, with erect reddish stems and narrow dark green leaves with red central veins, turning red and yellow in autumn. In summer it produces bright red and yellow flowers. Numerous cultivars have been selected for garden use, but it is a vigorous plant, and can be invasive.

Plant my griffith spurge

Avoid too rich soils. Euphorbia is growing fast! Prepare the soil by digging (to decompact without necessarily turning it, with a fork or a grelinette), scratching and raking. Plant the perennials at a spacing of 1/3 of the adult height between plants. Tamp the soil to not let air in contact with the roots, then water abundantly.

Water my griffith spurge

During growth, water once or twice a week. Water adult plants by big inputs even if you do it less often; the plant will develop a better root system if it has to fetch its water in depth. When watering, wait until the water that you pour stop rushing into the ground, and forms a small puddle. Unless otherwise specified, do not wet the foliage: plants "drink" by their roots.

Weed my griffith spurge

Avoid hoeing the soil too close to euphorbia strains because their roots are fragile. In the case of perennials, weeding also means arbitration in your massif; do not let the most vigorous develop at the expense of the slower ones.

Cut down my griffith spurge

The regular pruning of euphorbia is not essential. However, we can cut down the stems in spring or fall, to limit the development of the plant. Trim right after the end of flowering to prevent seeds from sowing spontaneously. Simply cut the flower stalks about 5 cm off the ground.

Propagate my griffith spurge

Propagation of shrubby euphorbia is by stem cuttings from March to June. If possible, keep warm (above 20 ┬░ C), with a good humidity, and take only the still green / non-lignified end of the stems, which will be more apt to form new roots.

Mulch my griffith spurge

Mulching the perennial plants will save you from watering and weeding and will even fertilize the soil a bit as it decomposes. When choosing, know that dry wood chips are the most inert, but they will last for a longer time. Fresh wood chips and leaves enrich the soil but must be changed often. Grass cuttings are to be used mixed with something else in a layer that is at most 1 cm thick. Mulch with a thickness of at least 5 cm to provide a good level of efficiency.
