Make a Hypertufa Trough

Molded concrete containers can be made in nearly any shape and size you want.

Alpine strawberries and herbs determine a home inconcrete planters , which harken back to the days when stone troughs obtain water for farm animals .

To make a hypertufa trough , you ’ll need peat moss , perlite , and Portland cementum . ensure you buy neat Portland cement . You do n’t require any of the pre - interracial concrete or mortar you ’ll determine on the market place .

You ’ll also need a few ounces of celluloid concrete reinforcing fibers , which fortify the planters . you may find the fibers at most Freemasonry - supply stores or online .

For mixing the ingredients you ’ll need a wheelbarrow or any large charge plate container . You ’ll want a screen or silver screen to sift the peat moss to remove sticks and hunk . And you ’ll need a stiff wire light touch to remove rough edges . Wear rubber eraser gloves while mixing and handling the mixture because Portland cement will irritate your skin . A low junk masque helps keep perlite dust from irritating your nose and lungs .

This project can be a bit messy , so pick your body of work area with that in mind . Part of make a planter is letting it cure for 12 to 24 hours until the cement and other component harden . undimmed , red-hot sun can cause spotty curing , and might make the plantation owner crack or fracture , so pick a suspect spot to make your planters .

You ’ll require a stout , flat open . I like working at a picnic tabular array . I enshroud the table with heavy plastic sheeting , which I tape to keep it from slide around .

Finding the best mold for the job

A planter ’s cast is limited only by your ingenuity and whatever possible molds you have on hand . Do n’t use wooden or alloy mold unless you first trace them with plastic , otherwise the mixture will stick to the molds and you will damage the planters when you seek to take them . The mixing wo n’t stick to cardboard , charge card , or Styrofoam mold .

To make a orthogonal planter , I use two nesting cardboard cartons as mould . The larger box functions as the outdoor form and the smaller box is target inside . This creates a space of 1 in . to 2 in . between the two boxes into which the mixture can be packed and tamp down down . A large trough will require thicker walls to asseverate strength and , therefore , more space between the two boxes .

mould can also be made from the polystyrene foam used for mansion insulation . The piece are held together with wooden cooking skewer . you may get this sort of foam at building - supply stores .

For a more free - var. looking at , you’re able to press the mixture over a plastic - udder - draped earthenware or wooden works container . Another alternative is to make a mound of grunge or gumption and then cover the mound with a formative udder .

Proportions for a proper mix

Measurements for the ingredients are not exact . Rough proportions are helpful , but finally you will develop a feel for how tight the premix should be . What you ’re after is a mix that ’s about the consistency of cottage high mallow .

Here are the jolting proportion for the mixture by bulk : two component Portland cementum , three parts sifted peat , three theatrical role perlite . You ’ll involve much less of the reinforcing fibre , about a smattering .

Here ’s another way of bet at it . To make an 18 x 12 x 9 - in . plantation owner , you need approximately 2 gallons of sift peat , 2 gallon of perlite , 1 - 1/3 gallons of Portland cement ( about 12 lb . ) , 1 cup of loosely packed reinforcing character , and water .

Measure the peat moss , perlite , Portland cementum , and reward fiber into a bicycle barrow or other large container . Using gloved hands , mix the ironic element .

impart water slowly , mixing with your hands until the material is the desire consistency . Grab a handful of the mixture , and stuff it ; it should hold together and only a few drop of piss should emerge . The total amount of water needed will depend on the waterlessness of the peat moss and the humidity in the atmosphere .

The mixture should n’t be fluid — too much weewee and you ’ll get a decrepit container . A free - form container want a drier mixture so that it will hold its shape .

Just like making mud pies

Every fourth dimension I make another one of these planter , I feel like a child do clay pies . It ’s sport !

When I apply the two - boxful method , I put a 1 - in . to 2 - in . stratum of the mixture on the bottom of the gravid box . Then I center the smaller loge inside the large and pack the admixture firmly between the side of meat of the two corner . When the side touch the desire height , I smooth and flush the top boundary .

If I ’m mold a planter over an turn over flower pot or a mound of soil , I begin by packing a 1 - in . to 2 - in . thick stratum of the mix around the bottom of my mildew . Then I work on up , adding more material until I progress to the top . I chuck the mix smooth and keep the top as plane and even as possible . This will be the bottom of the stack when it is turn over .

Planters require two stages of curing

Curing refers to the drying of the material and to the chemic soldering that takes place . cure has two stages : an other leg when the planter should not be moved , and a longer drying catamenia following removal of the mildew . The initial curing period choose 14 to 36 hours , while the latter takes about three week .

For the first 36 hour , cover your plantation owner with plastic . The charge plate give it bring around more tardily , and slower curing create a strong planter .

After a day and a one-half , I test the harshness of the mixture with my fingernail . If I can scratch the surface , the admixture is still too soft and should be left for a few more 60 minutes and then retested . When it requires a screwdriver to scrape the airfoil , the planter is ready for the second stage of curing .

Alpine strawberries and herbs find a home in concrete planters, which harken back to the days when stone troughs held water for farm animals.

I cautiously remove the mould from the planter , and then smooth the corners and harsh edges with a stiff wire copse . you’re able to texturize the plantation owner by scoring it with the brushwood . Be careful not to press too hard , as the wall are still crumbly . leave alone the plantation owner in a shady spot for about three weeks to stop cure .

After three weeks , the planter will be a light colour and will consider less . The last step is to leach out the solid alkali or free lime contained in the Portland cement . A heavy concentration of lime tree is harmful to flora . I leach aside the lime by filling the porous planter with water .

Over the next ten days , I fill again the plantation owner whenever it ’s empty . If you know where it rain down a lot , nature will do the leaching for you . I wish to make planter during the wintertime and leave them to leach until spring .

Dress up your container with evergreen sprigs or thick leaves.

Finishing touches

The planters are naturally holey , but if you want additional drainage , drill a hole in the bottom using a masonry bit .

I ’ve made scores of these planters , and have used them for herb — thyme , chives , sage , chervil , and mounding basil — and vegetables , too . Round carrot , baby beets , radishes , bantam Mei Qing Choi , and alpine strawberries adapt attractively to these pots .
