Choosing your soil

Choosing and preparing your soil

For roses, a good soil has a pH of about 7: a so-called "medium loam" is ideal for planting roses.

Alkaline soil

If your soil is alkaline, it will favour chlorosis. It is therefore important to remedy the situation by adding material which slightly acidifies the soil or temporarily removes the lime (heather soil or peat).

 

- Water with pure distilled vinegar and remove the deposit that forms on the soil surface. Repeat this operation if the rose starts to show signs of chlorosis (yellowing of the leaves).
 

- Dusting lightly with sulphur (2-300 g/m2), will also slightly alter the pH (degree of acidity) of the soil.

Spot where roses have previously grown

If you wish to plant a rose in a spot where roses have previously grown, it is best to replace the soil, as roses secrete toxins.

- Make a hole 70 cm deep and 40 cm in diameter and refill with good soil. If possible, this should be done at least one month before planting, to allow the soil to settle naturally.
 

- Before refilling the planting hole, add some fertiliser to the bottom which will feed the plant in the years to come (hoof and horn meal, wool, bone meal or feathers).
 

- Cover this layer of fertiliser with a layer of earth, so that it doesn’t come into contact with the roots when planting.
