How To Plant Hydrangea?
Planting Season: Start planting hydrangea in fall or early spring season.
Where To Plant: Plant them at a location where they can receive bright direct morning sunlight but get protected from the harsh heat of the afternoon.
Soil & Potting Mix: They can grow on wide range of soils. But well draining soil rich in organic matter is best. Avoid growing them in waterlogged soil as it can cause root rot. Prepare potting mix with 40% soil + 40% organic manure + 20% cocopeat.
How To Plant: To plant them in pots, dig the soil to a depth to which the roots of the plant can adjust appropriately. After placing the roots in the pot, cover them with soil around the base and apply water.
To plant them in the ground, dig the soil up to 1 to 2 feet larger than the root ball. Place the plant in the hole and ensure it remains a few inches above ground level. Cover around the base with soil adequately and apply water.

How To Propagate Hydrangea?
You can start propagating them by stem cuttings or tip layering in early spring season.
From Cuttings: Take 4 to 6 inches of softwood stem cuttings from just below a leaf node with the help of a pruning shear. Leave 2 to 3 leaves at the top and remove the rest. Dip the bottom end in rooting hormone powder. Plant cuttings in the pot & apply water. Keep checking moisture in the soil, and whenever needed, add water. Within few days roots will grow, and you will notice the growth of new leaves on cuttings.
From Tip Layering or Bent Over Branch: Select a healthy branch and bend it down so that a portion of that branch touches the ground. Remove leaves from that area where the branch is in contact with the ground soil. Take a small stone or brick and put it on the branch. Keep watering; once roots start emerging from the branch then, separate the new plant from the mother plant with the help of a pruning shear.
