Grow bamboo Phyllostachys Sulphurea Viridis (Ougon-kou Chiku Bamboo)

Cultivate in contained spaces

Phyllostachys Sulphurea Viridis can grow to 4 metres, an ideal bamboo for woodlands or large gardens. This evergreen bamboo is better planted in a site where visitors can admire the contrasting green and yellow colours.

Use large heavy-duty container pots to grow this Phyllostachys bamboo. It may not grow to its maximum height and spread when grown in contained spaces.

The new shoots in the second, third and successive years will be reasonably taller than the first shoots.

So, do not be surprised if your Phyllostachys Sulphurea Viridis is taller than an average Phyllostachys bamboo in the container pots.

This running bamboo will definitely require repotting within 3 – 5 years.

Cultivar for large garden and woodland

Phyllostachys Sulphurea Viridis’s evergreen foliage, upright bright stems and arching branches are ideal for thick garden hedge.

As mentioned, the spectacular green and yellow colours on the large woody stems make this bamboo the ideal candidate for large gardens and woodland forests.

5 Tips for Bamboo care: thin, prune, mulch, fertiliser and slug attack

Bamboos, like other plants, will require attention to grow well. The 2 tips are important when growing Phyllostachys Bamboos such as the Sulphurea Viridis (Ougon-kou Chiku Bamboo).

Thinning bamboo plants once or twice a year to promote new growths and keep the plant under control. Selectively trim the old culms that you do not want within the bamboo grove. In fact, the new shoots will produce a spectacular reddish colour after thinning.
Pruning bamboo is intensive work compared to thinning bamboo. Dig and remove the parts of the bamboo that have outgrown the allocated space. This is an ideal time to take the bamboo divisions for replanting.
Mulching is a highly recommended care and maintenance job. It keeps the soil moist and protects the bamboo from frost and frozen soils.
The bamboo leaves are fantastic mulch since they contain silicon which is naturally high in nitrogen. In addition, tree barks or other organic mulch rich in moisture are good for bamboo plants. The best time for mulching is early in Spring before the new bamboo shoots come out; or late in Autumn when you expect cold Winter.
Fertilising bamboo promotes healthy growth. Though bamboos do not need fertilisers regularly, the old plants will benefit from the added nutrients. Add fertiliser to plants that are older than 5 years at least once a year. The NPK fertilisers or any that is high in nitrogen are ideal options.
The large bamboos are pretty tolerant to pests, however, slugs will eat the tender shoots and leaves. If you are planting a new Phyllostachys Sulphurea Viridis or expecting fresh growth in Spring, add Slug and Snail Pellets to protect them.
