    Default horticultural sand

    hiya

    When you want to add sand mixed into some compost for drainge on a raised bed does it have to be horticultural sand or will B&Q sharp sand do?

    Thanks

    Hiya,

    I used B&Q sharp sand from the builders yard for my lawn and raised beds. Haven't seen any ill effects yet.

    Personally (and it is only what I do), I wouldn't add builders sand, I only add horticultural graded sand.

    Horticultural sand is usually lime free so can be used with ericacious plants but is relatively expensive and may not be that coarse.

    Grit sand or sharp sand from a builders merchant is much cheaper, will probably contain lime and is quite variable depending on source. Best to check a sample before buying - you want it fairly coarse

    having said that -not all that sure why you need extra drainage for a raised bed - being raised means it drains more. Is the soil clay? Is it based on concrete?

    I use builders sand on the garden and for making potting compost. I have a silty black soil and find it does some good, especially in the carrot patch!

    it has a wodden base , and the compost gets soaked when raining hard.
    and compost mixed with sand is good for carrots.

    but i dont know weather to get lime free sand or just sharp sand from B&Q

    If it has a wooden base, it doesn't matter how much sand you put in, it's going to get wet!

    Is it the same bed as the other thread?

    I've haven't had any problem using builders sand so far. Far cheaper that horticultural sand. I was worried at first about the salt content as builders sand is generally dredged from river channels, but I imagine the rain washes it out?
