What Size Pot to Plant Hydrangeas

If you love hydrangeas, but you have limited space in your garden or only have a balcony or patio to work with, planting hydrangeas in pots is an excellent solution. However, choosing the right pot size is crucial to the health and growth of your hydrangeas. In this guide, we'll explore the factors you should consider when selecting a pot size for your hydrangeas and offer some tips for potting and caring for these gorgeous bloomers.

Factors to Consider When Choosing a Pot Size

The first factor you should consider when selecting a pot size for your hydrangeas is the variety you plan to grow. Different hydrangea varieties have different root systems and growth habits. Some varieties, like the mophead hydrangea (Hydrangea macrophylla), have shallow root systems and do well in smaller pots. Other varieties, like the oakleaf hydrangea (Hydrangea quercifolia), have deeper root systems and require larger pots to thrive.

Another factor to consider is the size of the adult plant. Some hydrangeas, like the dwarf hydrangea (Hydrangea paniculata 'Little Quick Fire'), only grow up to 3-4 feet tall and can do well in smaller pots. Other hydrangeas, like the climbing hydrangea (Hydrangea anomala petiolaris), can grow up to 60 feet tall and require much larger pots to support their growth.

Finally, you should consider your climate and the conditions in which your hydrangeas will grow. If you live in a hot climate, your hydrangeas may require larger pots to ensure they have adequate moisture and root space. If you plan to keep your hydrangeas indoors or in a shaded area, they may do better in smaller pots.

Tips for Potting and Caring for Hydrangeas in Pots

Once you've selected the right pot size for your hydrangeas, it's essential to pot them correctly to ensure their health and growth. Here are some tips to help you pot and care for your hydrangeas in pots:

Choose a good-quality potting mix. Hydrangeas prefer a soil mix that is nutrient-rich, well-draining, and slightly acidic. Look for a potting mix specifically formulated for acid-loving plants or make your own by combining compost, perlite, peat moss, and vermiculite.

Add a slow-release fertilizer. Hydrangeas in pots will benefit from a slow-release or liquid fertilizer like fish emulsion or seaweed extract. Follow the instructions on the package to determine how much fertilizer to use and how often to apply it.

Ensure adequate drainage. Hydrangeas can suffer from root rot if their roots sit in soggy soil for too long. Make sure your pot has adequate drainage holes and add a layer of gravel at the bottom of the pot to encourage drainage.

Place your hydrangeas in the right spot. Hydrangeas prefer partial sun to thrive. Place your pots in a location that receives morning sun and afternoon shade. If you live in a particularly hot climate, consider placing your hydrangeas in a spot that receives dappled shade throughout the day.

Water your hydrangeas regularly. Hydrangeas in pots require more frequent watering than those planted in the ground. Water your hydrangeas deeply but allow the soil to dry out slightly before watering again. Do not let the soil dry out completely or become waterlogged.

Conclusion

Hydrangeas are stunning plants that can bring color and beauty to any garden or patio. By selecting the right pot size and following these tips for potting and caring for your hydrangeas, you can enjoy these showstoppers regardless of the space you have available. Remember to keep an eye on your plants and adjust their care as needed to ensure they thrive and reach their full potential.
