Best Soil

Hi GC

What would you say is the best soil or mix for container growing?
I used the standard garden centre compostlast year but wondered if there is anything else that is better suited.
I found that the compost dried out and had to be watered every day.
I have read threads on GC about water retaining gels which would cure the problem.
Could you tell me how much gel to mix into the soil as i would not want to add to much and drown the plants.

Thank You.

 

It all depends on what you want to grow really. Most composts have water retaining gel included. What do you want to grow?

 

Soil based compost mixed with 1/3 peat based or good leafmould.

I dont like water retaining gel as most does not biodegrade and prefer a layer of crocks and sharp sand at the base to retain water.

 

I use about two thirds multicompost to one third sharp sand. The sand helps drainage. But more recently, when potting up larger plants, I have mixed this in with an equal amount of soil from the garden. Without realising it I think this is about the same as the John Innes mix.

The reason for adding soil is 1) that I only use half as much compost (saves cost). 2) It is better at retaining water. 3) My clay soil has good nutrition in it, whilst the compost has little. I still feed regularly, but if I forget I feel the plants won't starve. 4) There is extra weight that could help prevent the pots blowing over. 5) I can leave the plants for several years in this (as long as I feed); pure compost breaks down with time into a very fine structure and then doesn't drain properly. and 6) I am mixing my soil intimately with the compost and when I have finished I return the mixture to the beds. This way I am improving my soil.

 

That sounds a good idea PeterS
