What a difference the PH level makes

Post by Balinbear on 20th January 2013, 21:56

Below are photos of two plants of Boarderer bred by Alister Clark

The first one is grown in our normal garden soil with a PH of 5.5

This one is growing in some garden blend that we purchased from the local hardware/landscape supplies. It was almost all chook poo (well not quite) and has a PH of 7.5. Both plants are cutting grown from the same parent. The colour is actully richer than shown in the second photo and the difference is amazing.

Yikes! That is amazing. Apart from bloom colour and intensity, are there obvious differences in growth pattern, foliage, general vigour? It would be interesting to see effects with other roses too. Anyone up for some experimentation?

The growth etc is pretty much the same just the intensity of the colour. I only got a small amount of the soil to top dress a bit of garden that had a very low PH.

This plant is growing where I wideneded the garden a little and thus is growing in the purchased soil (well about 6 - 9 inches then its down to the normal soil)

Not that is noticiable I don't think. I will have a closer look when I get a chance.

ok with a ph of 5.5 and 7.5 it would be interesting to see what is unlocked and locked up at those levels, and is a margin of 2.0 a significant factor

Two years ago I struck a cutting of Flemington Racecourse and subsequently it grew into a very small bush in a somewhat large pot. Despite all the TLC the plant didn't grow. After listening to a talk on pH I decided to test the pH of the pot and to my surprise it came out at 4. To cut a long story short I treated the pot with liquid dolomite some 5 weeks back and the bush is starting to take off.

Doug, isn't it interesting, we look at a plant and think what is wrong, we tend not to listen to the plant/soils. Where I live I have what would be considered fantastic soil, black loam, veggies and lucerne grow fantastic. There is a young farmer here which you would class as a "holistic farmer", when you speak with him he words are "I do not grow plants, I grow soil", in essence, grow soil, translates into growing plants.

Wise farmer. I once heard it expressed this way:
"Plant a $10 rose in a $50 hole." (Prices quoted were correct as at 1998. Allow for inflation).

The longer I am involved in growing roses the more I believe what the farmer said to be true.

What do you all recommend to raise the PH? Just the usual from Bunnings?

ok then...this might sound silly...but why do you want to raise ph, if you don't know the ph?....

I have a question which might sound silly. Our sewerage treatment plant water output always sits at 7.2 ph. Is this too high for my roses in the big garden that receives this water? Does that mean I need to check the ph more often. I have not checked it since last winter.
