Bamboo care: thin, prune, mulch, fertiliser and slug attack

Bamboos, like other plants, will require attention to grow well. Below are the 5 bamboo care and maintenance tips and best practices for growing healthy bamboos.

The tips are important when growing large running bamboos like the Phyllostachys rubromarginata (Reddish bamboo), especially in the garden.

Thinning 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

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 bamboo

Mulch 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

Bamboos do not need fertilisers regularly, but 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.

Protect bamboo from slugs

The large bamboos are pretty tolerant to pests, however, slugs will eat the tender shoots and leaves.

If you are planting a new Phyllostachys rubromarginata or expecting fresh growth in Spring, add Slug and Snail Pellets to protect them.
