Characteristics of Phyllostachys Aureosulcata 'Spectabilis'

 

Phyllostachys Aureosulcata 'Spectabilis' is a beautiful collector species not commonly available. The bright yellow coloration of the canes with the green stripe in the sulcus grooves adds a splash of color and is beautiful.

This rare species is one of the most cold-hardy species of temperate bamboo on earth and one of our most requested bamboos. This species can handle -5 degrees temperatures which makes it suitable as an evergreen bamboo for USDA climate zones 6 and warmer. Spectabilis growing habits are similar to 'Yellow Groove'; handles windy sites much better than 'Yellow Groove.

Phyllostachys Aureosulcata 'Spectabilis' grows quickly in zones 6, 7, and even tolerates the extreme heat in warmer zones 8 and 9. This bamboo can provide a dense screen in even the most unforgiving climates. In warm climates it grows quickly to 12 and 16 feet in height while remaining very bushy like with plenty of low growing limbs. It makes a great short screen in colder climate zones. Ideal for customer who need over ten feet of privacy.

How Bamboo Grows

Bamboo grows a little different than most plants. The bamboo that you get initially never grows vertically again. It has babies that are taller, that has babies that are taller. Every generation should be taller that the previous year's shoots. The intriguing aspect is that each year’s growth emerges and grows to it complete height in 60-90 days. They spread as they produce larger growth, filling in and providing a screen.

Planting Instructions

Planting bamboo is also easy. You want to dig a hole about twice the size of the root ball. When you plant the bamboo amend your soil with composted manure and a good top soil. Bamboo can be planted at ground level or slightly deeper. It is not a picky about it conditions but this will help get it off to a good start.

Spacing between plants

One division of bamboo will start a grove or screen over time. However, if you want a privacy screen fast, we recommend planting bamboo 3 to 5 feet apart. This will hopefully allow you to have a good screen in three years. There are a lot of factors such as water, sunlight, and climate zones that speeds up or slows down the process. Three years is about the average on this spacing, closer planting will allow you to screen or develop your grove faster. You cannot over plant bamboo.

Maintenance

Fertilizing

Bamboo can benefit from a fertilization program. You can safely fertilize your bamboo once it has been in the ground for one month. A time release fertilizer will work great. Time release fertilizers allow for proper absorption in case your soil is out of PH balance. We offer some fertilizer to help with growth. We fertilize twice a year. Once in the early spring to encourage new growth and then again during the middle of the grow season to replace any nutrients that are being depleted.

Control

Over the years a lot of myths have been told about bamboo, while it can spread under good conditions, it is not as invasive as many people would have you believe. In colder climates an aggressive runner here in the south will hardy spread at all in comparison. We have been growing bamboo since 1985 and had experience with it long before that. The bamboo's underground root system (rhizome) will spread beyond the initial planting over the years, so in the next two or three years you will need to decide on some method of containment on the sides you do not want the rhizomes to run over into.

We have constructed a page discussing multiple methods of controlling bamboo. It goes over root pruning, mowing new shoots, and in ground barriers: Controlling Bamboo

All this said and it may discourage you, but as with any plant there will be maintenance. Bamboo is very beautiful and is great in a Japanese style garden, but it will need maintenance down the road. At first it may seem to be doing nothing, but after 3 to 5 years you will have a lot of beautiful culms (canes) and love the foliage. All our 150 plus species simply contained by mowing and weed eating the new Spring and Summer shoots. Hopes this helps and don't be afraid of the bamboo.
