Just go to an Aquarium shop and ask them for something that will raise the ph then add this to your water or fertilizer mix and check with your ph tester then water into the plants
thanks... i will just do that this weekend. i guess the soil mix that i buy and make is just suitable for my roses.. as they need ph 5.5 to 6.6 .
my meter has a check for npk levels and it shows the level is in between the range "too little" and "ideal".
