Wetting agent - in tubs etc?

Is there something you could use as a wetting agents in tubs and baskets?

My parents have spotted some on a shopping channel. They say it stops the water just running straight through when watering - hence water saving etc.

But I was wondering if anyone had a home made version? That is also safe.   

You can buy water-retaining crystals in lots of shops and nurseries these days GF. The pound shops sell them. If they don't absorb the water quickly enough (may be too coarse), just give them a quick whizz in the food processor/blender. 

1. Saucer at the bottom of hanging baskets to retain water

2. Gel granules as suggested (wet them before adding to compost)

3. Use a solid liner in the baskets rather than a material one - I use an old shopping bag as an internal liner

4. Sponge isn't a bad idea but takes up quite a lot of room

5. As for an actual wetting agent - a drop or two (literally) of washing up liquid in the watering can reduces the tension of the water drops and therefore enables the water to better absorbed in the pots / baskets

Tried telling the parents that. 

I've learned stuff on here, so passed that bit knowledge on to them, but...... 

I know the feeling well GF...if they can afford it, just say 'yes, what a good idea' and let them get on with it! 

Hi,

I always water my hanging baskets/containers by putting ice cubes on the surface of the compost and letting them melt away. Water never runs through with this method.

 

good tip MOS, i will be doing that this year!
