play sand vs Horticulture sand

[Linda Enger]

Is there really any difference?  I have been finding that in my pots and containers that the compost or potting soil seems to actually get soggy and I have had gnat problems of recent and wondering if adding sand would help. I bought some play sand and at home saw label  NOT FOR ANY OTHER PURPOSES> , well I am one of those that never tore the label off the mattress so could use some help here. Could same help and does it have to be horticulture sand?

actually I was thinking maybe some said could help in drainage ( as compared to vermiculite or gypsum? )

I like the idea of 1/2 inch of play sand covering the soil so the gnats can't get back in and the larvae can't escape.

 

Fungus Gnats

Hey everyone thank you to all of your replies and your help! Yes, the "water bogging " of soil, as Vinnie mentioned really is an issue, and I would love a more economical way of making soil more workable. The ground soil amending is completely other issue but wondering if the pumice would be good to add to that as well?

One other option to consider (along with or in lue of sand) is using pumice as an added aggregate to you container soil mix. It can improve drainage; create better aeration and more even dry out; minimize soil compaction and clumping; and allow for moisture retention (not water bogging). I consider pumice a bit more versatile than sand, however, I typically use both together.
When mixing your soil, the pumice ratio should be heaviest toward the bottom 1/3 or the container.
As for the [fungal] gnat issue, it's kinda hard to 'undo' the situation once they are active without using chemical controls. They do not harm plants, though, just live in the soil. Using fly tape is very effective (though not sightly).
Best of blessings with your endeavor.
