I bought a summer hydrangea. it says to plant in alkaline soil, how do get my soil to be alkaline soil?

Before adding anything, have a soil test done to make sure your soil is truly acidic. If you do have an acidic soil...with a pH of 6.5 or lower, then you will want to add lime to your soil...to bring the pH up to 7.5 or higher. Be careful not to add too much lime. You can make your soil toxic if you reach a pH of 9. Good luck...Is it a pink hydrangea or something?

You can buy fertiliser with alkaline, however depending on where you live your soil may have enough already. Have a sample tested, usually you can get this done at your local college or garden store (a real garden store NOT Walmart!). Or you can add it by the old way, used coffee grounds.
Reply:Save yourself some time and money. Purchase a soil test kit from a garden center. You will then find out if your soil is already alkaline or acidic. Without knowing what type of soil you already have, you cannot amend it. The test kits are cheap, under $5 and super wasy to do.



With Hydrangeas you can plant in any soil you would like for bloomimg. If you like the blue/purple flowers it needs an acidic soil, if you want the pink ones it needs an alkaline soil. Be sure to test the area you wantto plant in for the best results. Good Luck

Reply:You can prob get an idea of your soil and its pH from your local nursery (REAL nursery) and they can advise you accordingly. You can also get fertilizer formulated specifically for acid loving plants, of which there are actually many. Note: you CAN get organic fert. for acid loving plants.
