Creating a cement form to secure a planter/tree

[dugaresa]

I got two urns for christmas that have trees that light up. I want them to be on either side of my front door. Problem is that they are not heavy enough to withstand the high winds in our area. So I am thinking of embedding them in a concrete base. I have the concrete but I need a form. can I use a cardboard box as a form?

Like a gift box?

Any comments would be appreciated.

1. There isa product called liquid nails.

you need a caulk gun and one tub of exterior grade heavy duty liquid nails.
Than glue those things to yer porch.

Otherwise you need at least one inch by four inch by what ever the total length you will need to create the concrete base around those things. You may be able to have the board cut to your dimensions and you can glue the forms together with liquid nails.

But the liquid nails will do it for you without the additional concrete base.

2. i would do that if they weren't just for christmas

however given your idea, I am going to use some concrete stepping stones i have and glue them to those
that way after the season we just take them down to the basement attached to the concrete stepping stone!

3. i think your idea would work, really.

if it was a good heavy duty box, and you mix the concrete nice and thick so it has a nice low slump. maybe you could brace up the box with some bricks, or blocks, or just wedge it into a corner. or wrap a couple loops of duct tape around it. you are not talking a half ton of concrete.
do oil it, tho. wd40 would be fine. helps slow water absorption, and makes sure the box will peel off.
