How To Make Virtually Free Plant Containers For Gardeners

A very cheap way or  free way  to make your own  plant containers  for outdoors or to disguise and protect those ugly plastic plant  troughs and pots bought from shops. . My neighbour was throwing out a number of discoloured and cracked plastic plant troughs and I have used all of them having disguised them with simple wooden boxes I made from recovered free sourced timber.

plastic troughs soon lose their integrity but for example, I used a saw to cut the  top off this broken one and built a wooden surround so it remained usable.

Plastic troughs soon lose their original colour and also their integrity because of sunlight  but for example, I used a saw to cut the top off this broken one and built a wooden surround so it remained usable & protected from further light damage.

Shop bought plastic troughs and plant pots tend to be sold in either green or terracotta brown and in my view don’t look as pleasing as the more expensive clay or wooden variants and of course the colour of the plastic fades over time because of the  elements and espeically sunshine as  ultra violet rays cause most plastics to deteriorate, lose strength and become brittle.

The alternartive , wooden troughs and barrels though  seem to be unnecessarily expensive for what they are and thus all the box plant containers in my little garden I actually made myself and in the main from found and /or reclaimed timber or i used  used recycled plastic containers which cost nothing. The  bonus for me  is that doing such things is  great for the environment- part of the fun is  finding practical uses for stuff most people throw away without a thought.

I like to have natural materials in my garden and thus either make my own containers made from reclaimed timber in simple box construction or use the same reclaimed wood to disguise a number of tired plastic troughs I have been given by friends and neighbours . I do this  either by boxing them in or, with smaller pots use slats of wood linked together.( I also make broad  re use of plastic food package containers or plastic  paint tubs in my garden and greenhouse )

How to make a large planter free from a used plastic paint tub

Clean emptyemulsion  paint tubs can be cut to depth to make free,strong durable plant pots.

Re-use clean empty emulsion paint tubs  cut to depth to make free,strong durable plant pots.

In the first example I have used one of several large emulsion paint tubs I have collected which of course cost nothing and this size is the equivalent of fancy thicker plastic planters which a well known large DIY chain is charging £8 a pot for or about three pounds a piece for the thinner basic large plastic plant pot!

I have collected a number of empty 15 litre plastic emulsion paint tubs from various free sources. Emulsion is really easy to scrub off the inside of the tub (whereas oil based paints are much more problematic. )  This size of tub is an ideal size for example for growing individual tomato  plants  or small shrubs and conifers. Shop brought mass produced  standard  plastic plant  pots are usually very thin by comparison while  such lidded paint tubs  are stronger, thicker  and deteriorate far slower than shop bought pots.  (Ultra violet light from the sun degrades most forms of plastic and that is another reason for considering disguising them with a simple wooden surround since it prevents UV rays from  affecting the integrity of the material. )

Thoroughly wash out the remnants of emulsion from the 15 litre tub. Use a paint scraper to remove the excess dried on solids on the inner edges  then finish with an abraser scouring pad

If you prefer why not add a coat of black emusion paint to cover the lettering or discguise as a barrel as shown elsewhere in this blog entry. this size is more than adequate for a single tomato plant, small fruit bushes and shrubs.

Where you want a shallower planter or cutting down a larger capacity paint tub I use masking tape around the perimeter to enable me to straight  cut the tub down to the depth/size I want and then drill one or two drainage holes in the bottom. Then since some of these pots will be on display and not in the greenhouse I disguised them with wooden slats making them barrel like and at no cost siocne all the materials were reclaimed.

I simply measured the depth and the circumference of the pot and cut the requisite number of slats which would go all the way round the pot to make it look more pleasing and natural ( making the slats a centimetre or so longer than the depth of the pot so the pot  cannot be seen when wrapped in the slats. ) Originally I used  stiffer plastic coated garden  wire nailed to the wood  to hold the pieces together but actually twin flex wire or thin  telephone cabling is much easier to work with . Simply lay out the slats you have cut in a row and use carpet tacks or panel pins hammered at intervals through the wire and into the wood . Knock the nail over to hold each piece firmly together.

I have used a similar fixing  techinque using cut to size short thin logs from branches of one of my trees I had trimed split into halves as in this example.

here ~i have cut thin logs to length a little taller than the plant pot, split them and used the telephone wire technique described earlier to hold them together in a ring to disguise the plastic pot and protect it from Uv rays.

How to Make your own low cost wooden plant troughs

The cost of wooden plant troughs and planters to me seems pretty steep and I doubt whether prices genuinely reflect the actual production costs and yet they are so easy to make yourself. I use a range of wooden planks and ocasionally reclaimed laths from discarded pallets i deconstruct first which I have collected here and there in my locality which means there is no cost in making wooden plant containers. i am not particulalry bothered about having planters which are not alln of the same material but if you want style untiy  you could also watch out for special offers on decking planks if you want garden planters to look co-ordinated and made from exactly the same material. It comes in two and three metre lengths  sometimes for as little a three pounds a length , especially at times of year like now when the stores don’t think there will be much demand. This timber looks attractive , is substantial but also treated so it is normally guaranteed to last ten years or more. Because it is thicker than say standard flooring planks it is actually easier to construct simple boxes from it and it doesn’t split as easily when screwing cut lengths together to make the box construction. Decking screws are relatively cheap and also treated for outdoor use and do not require drilling “pilot” holes and can be driven straight into the wood . for that I use a cordless screwdriver which makes very light work of cosntruction. Some timber merchants will cut decking boards to your requirements if you give them a cutting list ( for a small fee.)

Decking board is cheap, solid, attractive and long lasting for making wooden plant boxes.

Whether you are making a stand alone trough or a box to be lined with a pre-bought plastic trough to disguise it , the same simple technique of box construction is employed and you will need a front, back and two shorter sides. Here are the tools I use :-

This is probably the most usedful tool for anyone - a small powerful but lightweight cordless screw driver and drill - takes all the work out of screwing your sections of wood together. chose one with a Lion battery- slightly more expensive but charges quickly, doesn't lose its charge as nicam rechargable batteries do.

Once you have measured out your lengths to make the sides and ends of your box and marked out take care cutting to length letting the saw do the work. Take one long piece and one of the two side peices and butt them together  as in this image. This way you can’t see the sawn edge of the side piece when you have screwed the front to the side. I use decking screws because they cut their own hole, don’t split the wood and are coated to last outdoors.

the long front peiece is butted at right angles to one of the sides and screwed together as shown.

This should guarantee perfectly square corners. This planter I made from a deconstructed wooden pallet I found with three pieces forming each side. This method works well with thinner material like this and also holds together the composite of pieces making up each side

 

Cut a further length and screw to the bottom of the box for stand alone planters and don’t forget to drill a couple of drainage holes. Line the inside edges with plastic sheeting to extend the life of the wood. Here’s how I do that :-

How to line wooden plant containers neatly and easily

Turn trough on its side and measure walls and add an inch to  the depth to allow for the lining to fold over the wire.

I  attach sheets of tough polythene to the inside surfaces of my home made containers to slow down the process of the wood deteriorating by direct contact with wet soil and bugs sometimes using cut down old rubble or compost bags. To avoid the need to fold and tuck corners  I cut lengths of polythene to fit each inner face of wood but adding say and inch to the depth to fold over to form a neat finish. I place the polythene in place as shown in the photo and pin through  the telephone wire I have cut to length. You then simply fold the sheet over and into the box repeating the procedures both inner sides and ends. ( Don’t  forget to drill a few drainage holes in the bottom of your container .) Because you are using separate sheets excess moisture can find its way into and out of the drainage holes)  Note how the edge of the wire/ folded top edge  is roughly half an inch below the lip of the container so , when filled with soil /growing medium, the inner lining is barely visible but you have a very neat edge when the soil is added .

You get a neat edge like this when the soil is pressed agianst the plastic lining.

Make a ready made plant trough simply from a discarded wooden book case 

I had both a pine book case I made and a wooden CD double library case both of which became redundant in my home so I simply cut them down with a hand saw to make additional planters as follows in this illustrated example using the CD storage case.

check where the shelf comes , reverse the case and carefully mark out you cutting line. Be patient and don't force the saw -let it do the work for you and it is as easy as cutting bread.

the separated section of the CD case- it has a thin ply back as much of this kind of furnature does but will be fine if the planter is going to be on a flart surface. Screw or nail a stronger piece of timber to the underside if you want it stronger and more durable.

Other items used as plant containers outdoors

A non stick large wok that had lost its unstick- not hard to drill a couple of drainage holes in its bottom and this one planted up with flowering shamrock bulbs ready to flower in June.

to fill a narrow available space on top of our boundary this is simply a section of a pallet two boards wide and great for single plants in a row.

And finally a range of the kind of plastic food and drink packaging that I save for use as improvised plant pots and seed trays.

a rnage of plastics are not widely recycled but can still be reused as improvised pots and seed trays.
