Choosing the right location

The soil should also be moist and well-drained. Hydrangeas do not like to sit in water, so make sure the soil has good drainage. If you have sandy soil, you may need to add some compost or peat moss to improve drainage.

Planting

Once you have chosen the right location, it's time to plant your hydrangea macrophylla blue shrubs. Dig a hole that is twice as wide and as deep as the root ball of the plant. Add some compost or peat moss to the bottom of the hole, and then place the plant in the hole. Backfill the hole with soil, and water the plant thoroughly.

Watering

Hydrangeas need to be watered regularly, especially during the first year after planting. Water the plants deeply, so that the water reaches the roots. In most cases, you will need to water your hydrangeas once a week. However, if it is hot and dry, you may need to water them more often.

Fertilizing

Hydrangeas also need to be fertilized regularly. You can use a balanced fertilizer, such as a 10-10-10 fertilizer, once a month during the growing season. In the fall, you can apply a fertilizer that is high in phosphorus, such as a 5-10-10 fertilizer.

Pruning

Hydrangea macrophylla blue shrubs do not need to be pruned heavily. However, you should remove any dead, diseased, or damaged branches in the spring. You can also prune the plants to shape them or to control their size. If you want to encourage more flowers, you can prune the plants in the fall.

Winter care

If you live in a cold climate, you will need to take some steps to protect your hydrangea macrophylla blue shrubs from the winter weather. In the fall, mulch the plants with several inches of organic matter, such as straw or leaves. You may also need to cover the plants with a burlap sack or other protective material.

Troubleshooting

If your hydrangea macrophylla blue shrubs are not thriving, there are a few things you can check. Make sure the plants are getting the right amount of sunlight and water. You may also need to fertilize them more often. If the leaves are turning brown, it could be a sign of a nutrient deficiency. You can test the soil to see if it is lacking in any nutrients.
