Landscaping is vital to almost all backyard/ front yards anything.. but what do you use to create those cute beds of flowers, or veggies?
There are many options to choose from but first decide on a budget.. more and more people in this day and age are having money problems.. do you let your lifestyle suffer? Not if you are frugal!
Bricks or concreate pieces make a great box they are expensive if bought new.. but instead check out any demoltion site, or building site.. normally they are lugging away concreate and bricks that can be soo useful in a garden
Wood.. I use mostly wood which has a downside it eventually rots and must be replaced, and because this rots and decomposes you MUST make sure the wood you use has not been treated with any chemical (at least if your organic and I strongly urge you are).. home depot has landscape wood used for this purpose its $4 per 8 ft piece.. this can become pricey if you are boxing a lot of space.. but watch for sales every couple weeks those $4 pieces drop half off to $2..
Containers.. 1 gallon, 3 gallon, 5 gallon buckets on hand? Fill them with rich dirt plant something in it then make a garden box using those...
Anything that is solid can be used to make a garden box so go crazy and have fun!!!
