With immense flower heads, hydrangeas flaunt an old-fashioned charm in summertime that’s hard to resist. While these flowering shrubs are low-maintenance, proper care will keep them blooming.
Choose a location so that the hydrangea can reach its full size without pruning. Plant the hydrangea in well drained soil. Make sure to not plant the hydrangea too deep in the ground. Plant at the same depth as the in the pot it comes in.
The best time to plant hydrangeas are early summer or autumn. If you want to transplant a hydrangea, do so once the plant is dormant and has lost all leaves in late autumn or winter.
Water at a rate of 3cm per week throughout the growing season. It’s better to deeply water 3 times a week than sprinkle water in a shallow manner. This encourages root growth. The location of the plant will also determine how much water the plant needs. Typically, you will be able to tell when the plant needs water by looking at the foliage. The leaves will start to wilt when the plant needs water.
Fertilizer will not change the color of the blooms. It's possible that extra ingredients added to fertilizers might change the color, but the fertilizer itself doesn't have this power. It is much easier to change a hydrangea from pink to blue than it is from blue to pink. Changing a hydrangea from pink to blue entails adding aluminum to the soil. Changing from blue to pink means subtracting aluminum from the soil or taking it out of reach of the hydrangea. You cannot change the color of white hydrangeas.
Hydrangeas like morning sun, but do not do well if they're in direct, hot afternoon sun. Partial shade in the later parts of the day is ideal for these beauties.
Propagating hydrangeas is typically done from cuttings as the shrubs rarely produce seeds to use. It typically takes about 4 weeks to root from cuttings that are 6 inches long. While propagating, keep the plants out of direct sunlight so the leaves don’t burn up.
Hydrangeas can be toxic to cats and dogs if eaten. They are great air purifiers.
