Need deckboard planter lining and soil advice
Hi All,
I am a novice at gardening - I recently moved into my new house and since most of the front garden was paved over, I have just built some very large planters using decking boards that were left over from a patio decking project. I plan to grow hedging, topiary and other plants in it. I actually need two bits of advice. 1) The deckboards are untreated. What is an easy way to protect the inside of the planter from rot due to the damp soil? Should I line with with plastic liner or is there any way I can "treat" it? As there are 8 planter, each 2.4 meters long, I am look for the easiest solution. 2) As I mentioned, I am planning to grow hedging, topiary and maybe some flowers in the planters. What soil mix do I need? I was planning, 3 parts loam, 1 part compost (with peat) and one part builders sand. I have already ordered the compost as there was a deal in my local DIY shop. Please let me know if this is a suitable mix? How much drainage do I need? Many thanks for any help. Regards, T George |

Regardless of what you put inside them I'd give them a good coat of one of Mr Cuprinols' preservatives to extend their life. ormally you'd have a plastic liner ( a large tub of sorts) and cut the boards to box it in to suit - tub first, woodwork second if you see what I mean. It's quite normal to make a lip around the top to obscure the top edge of the liner. I dont doubt you could make a soft liner inside with some sort of imperiable sheeting, but the weight of that much soil/compost would certainly test your woodworking skills and design! Don't forget that the tub inside will need drainage holes at the bottom to avoid waterlogging, and those will need covering with crocks and large stones to avold the soil blocking them. As to filling them I'll leave others to comemnt apart from saying that peat substitutes are to be preferred on ecological grounds. |
