Mock-orange best copes with being pruned every year, so that young branches have a chance of growing and old wood is eliminated.
- After the blooming, prune the year’s new growth back to half its length.
That helps renew the vigor of your mock-orange and stimulate the next blooming.
- Cut at their base the oldest branches more or less every 3 years.
- Also eliminate dead stems and any weak ones you might see.
As for watering, mock-orange must be watered in case of high temperatures and/or of extended dry spell.
- It signals that it needs water when the leaves start drooping slightly and feel softer to the touch.
Potted mock-orange must normally be watered much more often than that planted in the ground.
- Water as soon as the soil is dry down to about an inch (a couple centimeters).
All year long, it is important to clear around the foot of the mock-orange to remove weeds and ensure the water drains well around the roots.
