Bamboo


Leon and I were interested in planting trees, bushes and flowers to beautify the property and reduce erosion. We were able to get over 200 plants for free from the Department of Natural and Environmental Resources DRNA, mostly consisting of different varieties of palms and we bought hundreds of small mani plants for ground cover. Over time we continued to add different types of bushes, shrubs and flowers with some successes and some failures. Some of our favorite plantings are the various species of bamboo we planted on the east side of the property. We heard there is a man in town that goes by the name Bamboo Joe. He has 12 cuerdas (approx 12 acres) in Barrio Cruces covered in bamboo and various hard woods that he planted himself. Bamboo Joe was offering a tour of his property for anyone interested in seeing what he was doing. It turns out he built his house out of bamboo as well as furniture, lamps, toys, and tree houses too! Joe has created his own bamboo jungle unlike anything I’ve ever seen.

We were so impressed with the beauty of the bamboo garden that decided to hire Joe to plant bamboo on our property, Dos Ceibas. We already had one large patch of bamboo on the property that's been there for many years and it’s a special spot on the property for us. In fact we named one of the lots “Bamboo” because of it. The tranquility and shade it provides is a unique aspect of the bamboo patch. We love the noise it makes when the wind rusltles the leaves and makes the stalks rub against one another. The fallen leaves also provides a unique ground cover. We planted various types of bamboo as a screen on the north side of the property which has the closest proximity to a neighbor. We're looking to create a natural barrier on the border of the cano.

Here are a few species of bamboo we planted:

Bambusa Textilis, also called weavers bamboo. It's wind tolerant, compact, ideal for hedges and can grow up to 40 feet in height.

Bambusa Vulgaris, also called common bamboo has feathery yellow and green leaves. Its known to be great for erosion control and can grow up to 40 feet in height.

Dendrocalamus Asper, also known as giant bamboo can grow up to 4o feet in height. It has spines and sharp edges and grows really fast with large bright green leaves.

Bambusa Tuldoides is also known as buddhas belly because of the swollen sections called internodes. Buddhas Belly can grow up to 70 feet tall with zig zagging lowers culms! It's one of the largest bamboo species around. Obviously these are great for foliage and a privacy screen The height can also be stunted when put into pots and used for ornamental decorations.

Rainwater Harvesting Rincon, Puerto Rico

The tropical climate in the Carribean is ideal for collecting rainwater. With daily afternoon showers, and heavy downpours in the rainy months, clean fresh water is plentiful. Bigprototype designed a rainwater catchment system to take advantage of this resource for the Little Malibu house at Dos Ceibas.

On the upper floor of the house a shade structure doubles as a water funnel to collect fresh rainwater. The rainwater catchment is located high up on the structure to keep the pan clear of dirt and debris. The total area is 128 sqft that gently slopes to a drain at the edge of the catchment.


From the drain the water flows down thru the center of concrete column in a 2" diameter PVC pipe which terminates in a 600 gallon tank. We use this tank to run our toilets throughout the house and to water the landscape. This also provides the opportuity to maintain a local source of freshwater when the municipal supply is down - a frequent occurence in Puerto Rico!


Our system is gravity fed, taking advantage of the topography of our site. A 2" overflow valve is run from the top of our tank to an external drain preventing backups when we have unusually heavy rains.

Keeping Dirt in its Place


Puerto Rico's coast is fringed with coral reefs and Rincon is home to one of the healthiest elkhorn coral communities in the Caribbean. Sediments that enter the water system and which end up in the ocean can kill corals by blocking the sunlight these reefs need to survive. There are many simple methods that can be implemented by real estate developers and home builders to reduce the amount of sediments that leave a construction site.

The easiest thing one can do in Puerto Rico is to do all earth moving during the dry season.

Home builders and contractors should install Sediment Control Devices like hay bales and silt fencing.

Another sustainable strategy to reduce sediments is to work with nature and plant in the disturbed area.

As soon as we had completed the grading for our road at Dos Ceibas in Rincon, PR, we planted over 2000 plants, shrubs and trees on the roadsides to help stabilize the soil and reduce erosion. These plantings are more than decorative, they are functional.

In this case, adding green is going green.
