Planting and Care

Planting your Moonrock™ is easy.

Dig a hole twice the width of the pot, and deep enough so that when you place the plant in the hole, the top of the root ball is level with the ground around the hole. Fill in the space around the plant with a planting soil mix (you can buy this where you buy the plant) and press the area down with your foot.

Give the plant a good watering to help it settle in.


Your plant will do well with additional water when it’s hot. But to see its fuller potential, follow these steps!


An easy way to keep weeds down around your plant, and to keep it moist with less watering is to throw a 2 inch layer of mulch around the base of the plant – basic bagged “landscape mulch” from your local garden centre will do the trick.


Your Moonrock™ won’t need a lot of fertilizer, but it will benefit from a shot of good all purpose fertilizer in the spring when the leaves start to sprout. A fertilizer with a higher middle number (e.g. 15-30-15 or 5-10-5) will work best.


The best time to do a little trimming on your hydrangea is in early spring, just before it starts to grow again (just after you see signs of life is okay too). Removing dead flowers from the previous year is a good start. You can also cut back the top 1/3 of the woody branches.
