When to plant hydrangeas
Fall is the best time to plant hydrangeas. If you happen to be too late with planting hydrangeas, spring is still a good season to start planting. The only rule for planting hydrangeas is that the soil can’t be frozen. Hydrangeas need time to establish a good root system before blooming.

The best location for hydrangeas is one that receives morning sun and afternoon shade. If you live in a cool area, hydrangeas will tolerate more sun. Hydrangeas are low-maintenance garden plants. Please follow our step-by-step guide, this will lead you to shiny, frothy flowers during late spring and all summer:
- Hydrangeas need a large space to reach their mature growth. Choose a wide site if you want your hydrangea to reach its mature height.
- Hydrangeas thrive in fertile, well-drained and moist soils.
- Choose a full sun to a partially sunny spot. Hydrangeas love the morning sun, but rather avoid the heat of the afternoon.
- Hydrangeas love a humid environment-don’t plant hydrangeas under a tree. This causes competition for water and nutrients.

How to plant hydrangeas
Planting hydrangeas is very straightforward. Before you start planting, make sure your soil is well prepared. If you want your plant to start off healthy, enrich your soil with up to 15% organic matter and an all-purpose slow-release fertilizer.
- Dig a hole that is two times wider than the root ball.
- Hydrangeas don’t like to be planted too deep, stay close to the surface if you plant them.
- Mix in organic matter and the amended soil.
- Water well and keep the soil moist during the first weeks.
If you’re planting hydrangeas in a group, space at least 3 ft (30 cm) apart (more, if planting larger varieties) such as hydrangea macrophylla.
Hydrangeas in pots
Hydrangeas are suitable to grow in pots. Because hydrangeas like humid soils, smaller pots are less suitable for hydrangeas. Smaller containers dry out too fast for what hydrangeas prefer. Smaller pots give too little space for the aggressive root system. Choose larger pots or containers, so the hydrangeas root system has enough space and the soil doesn’t dry out too fast. excellent plants to plant in containers, flower pots or planters. Use a bagged potting mix rather than garden soil. If you don’t have a large garden, place your hydrangeas in the morning sun, so you keep them from drying out too soon.
Here’s how to plant hydrangeas in pots:
- Choose a pot that is at least two times wider than the nursery pot.
- Make sure you use a pot with drainage holes.
- Fill the bottom of the pot with hydro grains and mix the all-purpose potting mix with a slow-release fertilizer.
- Leave about 8 cm of space between the surface of the potting mix and the rim of the pot.
- Water regularly by filling the pot to the brim with water, letting it drain, and repeating.
