A hypertufa is an anthropic rock that consists of numerous aggregates that is mixed together using Portland cement. It is inspired by a naturally-occurring rock called tufa which can be usually seen from springs abundant in lime. Most hypertufas are set up as garden adornments. Probably the most popular forms of hypertufa are gardening troughs, as they are extremely tough and have the ability to withstand intense winter temperatures, as opposed to concrete pots. Hypertufa troughs are also easy to create and can be done using household items. And listed below are the instructions on how to build one on your own.
The components necessary for a hypertufa trough is 1 part Portland cement, 1 1/2 parts peat moss, and 1 1/2 parts perlite. You will also need a mold for your trough. Choose an item that has a structure that can hold plants such as oxes, buckets, pots, styrofoam ice chests, metal containers and so on. Also, cover your mold with a plastic or garbage bag so that it will not cling on your hypertufa mixture. Besides that, you can also make use of oil lubricants if your mold is made of plastic.
The initial step in making your hypertufa trough is combining the ingredients with water. Mix it until you achieve a firm moldable consistency. Next transfer the mixture to the mold that you’ve selected. Fill the mold to attain the preferred figure and make sure that you leave no spaces behind by compressing the mixture. If you plan to put plants in that trough, it is advisable to include drainage holes at the bottom using sticks or dowels.
After stuffing the mixture in your mold, you have to cover it up with a plastic bag and set it in an place where it won’t be disturbed. In about 24 to 36 hours, your trough will solidify enough so that you can already get rid of the mold. If you want, you can smoothen the top and edges utilizing a wire brush. Then, rewrap the trough with the plastic and let it sit once more for over three weeks, occasionally moisturizing it with water every now and then. You’ll know that your trough is already totally cured when it makes a hollow knock when you tap it.
As a ultimate note, before placing a plant in your trough, make sure that you leach it first using water for over the following ten days or so. The freshly created trough contains plenty of lime that are bad for plants and therefore it is not recommended to make use of it immediately after curing it.
