Hydrangea Types and Recommended Varieties for Pots
Hydrangeas are popular and easy-to-grow plants, perfect for your garden pots. Let’s look at the different types and some recommended varieties for container planting.
Mophead and Lacecap are both types of Hydrangea macrophylla. They are known for their large, eye-catching flowers. Some great options for pots include ‘Wee Bit Grumpy’, ‘Paraplu’, ‘Endless Summer Pop Star’, and ‘Cityline Paris’ source.
Mountain hydrangeas are a variety of Hydrangea serrata. They are smaller than other hydrangeas, making them ideal for container gardening. Try varieties like ‘Bluebird’ and ‘Tiny Tuff Stuff’ for your pots.
Smooth hydrangeas, or Hydrangea arborescens, have round flowers and adapt well to containers. ‘Incrediball’ and ‘Invincibelle Spirit II’ are two selections that perform well in pots.
Oakleaf hydrangeas (Hydrangea quercifolia) are known for their oak-like leaves and cone-shaped flower clusters. Smaller oakleaf varieties like ‘Pee Wee’ and ‘Munchkin’ suit containers well.
Panicle hydrangeas (Hydrangea paniculata) have long, cone-shaped flowers which can handle more sun than other hydrangeas. Compact varieties like ‘Little Lime’ and ‘Bobo’ are great choices for pots source.
Remember to provide the right amount of sunlight, water, and care for your chosen hydrangea variety. By selecting suitable varieties for container planting and giving them the right conditions, you’ll have beautiful, thriving hydrangeas to brighten up your pots and garden.
Selecting the Right Container and Location
When planting a hydrangea in a pot, it’s important to pick the right container. The perfect pot should be at least 18 to 24 inches deep and wide, giving the plant’s roots plenty of room to grow 1. Make sure the container has adequate drainage holes, as insufficient drainage can be harmful to the plant.
Pot size matters a lot when it comes to hydrangeas. These plants develop large root systems quickly, so choosing a container at least 24 inches (2 feet) wide is essential 2. Keep in mind that a hydrangea in a small or medium container will need to be repotted after two to three years.
Selecting the ideal location for your potted hydrangea is key to its growth. Different types of hydrangeas have varying sun tolerances. Mountain, smooth, panicle, and bigleaf hydrangeas perform best in areas where they receive four to six hours of sun each day 3. Panicle hydrangeas can still thrive with six or more hours of sun exposure.
Morning sun is preferable for hydrangeas, as it’s gentler on the plants compared to the harsh afternoon sun. Choosing a spot with afternoon shade will help protect your hydrangea from excessive heat and light. Always ensure the location has suitable sun exposure and drainage for the specific type of hydrangea you’ve chosen.
In conclusion, selecting the right container and location is vital for a healthy, happy hydrangea. Pay attention to pot size, drainage holes, and sun exposure to ensure your plant thrives in its new home.
Potting Soil and Planting
Choosing the right potting soil is essential for the well-being of your hydrangea plant. The ideal soil mixture is a blend of high-quality soil, compost, and organic matter. This mix provides nutrients, encourages growth, and allows proper drainage for your potted plant.
To begin planting your hydrangea, first, select a pot that is large enough to allow the roots to spread. Fill the pot with the previously mentioned soil mixture, ensuring that the pH level is around 5.5 to 6.5, as this is the optimal range for hydrangeas. This is important because the soil’s pH can affect both the plant’s health and the color of its flowers.
Now, dig a hole in the soil, which should be deep enough to comfortably fit the hydrangea’s roots. Before placing the plant in the hole, gently loosen the roots to encourage better growth. Once the roots are loosened, position the hydrangea in the hole and start filling it in with the remaining soil mixture. Be careful not to bury the plant too deeply, as this can lead to root rot.
After planting your hydrangea, it’s essential to give it a good initial watering to help the roots establish themselves in the new environment. Following that, maintain consistent moisture in the soil but avoid overwatering. Too much water can cause root rot, while too little may prevent the plant from thriving.
In summary, using an appropriate mix of soil, compost, and organic matter is vital for optimal hydrangea performance. Additionally, proper pH levels, planting depth, and watering habits contribute to maintaining a healthy potted hydrangea.
Watering and Fertilizing
When caring for hydrangeas in a pot, it’s crucial to pay attention to their water and fertilizer needs. Hydrangeas love moisture and require more frequent watering than those planted in the ground.
Make sure to provide enough water so that the soil stays consistently moist. However, be careful not to overwater, as this can cause root rot. A good rule of thumb is to check the top inch of soil each day. If it feels dry, give the plant a drink. Preferably, water your hydrangeas early in the day, to minimize water loss due to evaporation.
Choosing the right fertilizer is key to maintaining healthy hydrangeas. You can opt for organic or inorganic fertilizers, depending on your preference. Inorganic fertilizers often have time-release ingredients that feed the plant over several weeks or months.
For the best results, it’s important to follow the specific application instructions on your chosen fertilizer. In general, it’s a good idea to fertilize hydrangeas at the beginning of the growing season, usually in late spring or early summer. However, avoid fertilizing too late into the fall, as this may encourage new growth that could be damaged by winter temperatures.
In conclusion, proper watering and fertilizing practices are essential for keeping your potted hydrangeas healthy and thriving. By giving them the right amount of water and the appropriate nutrients, you’ll be able to enjoy lush, beautiful blooms for years to come.
Sunlight and Shade Requirements
Hydrangeas are pretty adaptable when it comes to sunlight and shade. However, it’s important to know their specific requirements for the best growth. Generally, hydrangeas need a mix of full sun, dappled sun, and partial shade. Let’s talk about each one so you can find the perfect spot for your potted hydrangea.
When thinking about full sun, it means your hydrangeas should receive at least six hours of direct sunlight every day. However, not all types have the same tolerance for full sun. In fact, mountain, smooth, panicle, and bigleaf hydrangeas do best when they receive four to six hours of sunlight per day.
On the other hand, partial shade refers to areas where your plant can get between three and six hours of sunlight. This is great for hydrangeas as it helps them have healthy growth while avoiding harsh rays. Remember that too much sun could cause your hydrangea to dry out.
Dappled sun is another term for areas with filtered sunlight. This can be found under the shade of larger plants or trees. It’s where the sun comes through in patches, giving your hydrangea bursts of sunlight and periods of shade.
Bright, indirect light is something your potted hydrangea will also appreciate. This type of light is found near large windows or glass doors where direct sunlight is not hitting the plant but still providing good illumination.
After figuring out the sunlight and shade requirements, place your hydrangeas in a spot that receives full sun in the morning and some shade in the afternoon. This will help them grow strong and healthy in your pot.
By understanding your hydrangea’s sunlight and shade preferences, you are setting your plant up for success. Now that you know the basics, you can confidently choose the right spot for your potted hydrangea to thrive.
Pruning and Deadheading
Hydrangeas in pots need some extra care, but don’t worry! With a little attention, they’ll thrive. Pruning and deadheading are essential steps for keeping your potted hydrangea healthy.
Pruning is all about trimming the plant to promote growth. The best time to prune hydrangeas is in late winter or early spring, before new growth appears. When you prune, make clean cuts just above the fresh buds. Remove any dead or damaged stems as well. It’s important to know if your hydrangea blooms on old wood or new wood. Old wood bloomers should be pruned after flowering, while new wood bloomers can be pruned in late winter or early spring.
Deadheading is the process of removing spent flowers. This encourages the plant to produce more blooms and maintain its beauty. You can deadhead hydrangeas throughout the blooming season. Use a pair of bypass pruning shears for clean cuts without crushing the stems.
Here are some simple steps to prune and deadhead your hydrangea:
- Sterilize your pruning shears to prevent the spread of bacteria or fungus.
- Identify the type of hydrangea you have (old wood or new wood bloomer).
- Prune old wood bloomers after flowering, and new wood bloomers in late winter or early spring.
- Deadhead throughout the blooming season for continuous blooms.
Caring for your potted hydrangea doesn’t have to be complicated. With proper pruning and deadheading, you’ll enjoy beautiful, bountiful blooms all season long!
Winter Care and Protection
Caring for your hydrangea in a pot during winter is important to ensure its health and ability to bloom the following year. When winter months approach, you’ll need to focus on protection to keep your hydrangea thriving.
First, keep an eye on the temperature. Hydrangeas are not fond of freezing temperatures, and being in a pot makes them more vulnerable to cold damage. If the temperature consistently drops below freezing, consider moving your hydrangea indoors for the winter. Place it in a cool, bright room where it can still receive some natural light. Otherwise, find a sheltered location near your house or another structure for added protection.
Make sure to water your hydrangea sparingly during winter. The plant’s roots shouldn’t sit in water during its dormant period. Add just enough water to moisten the soil after it dries out. Too much can lead to root rot or other health problems.
Additionally, create a winter protection barrier for your potted hydrangea. Wrapping the pot in insulating materials like bubble wrap or burlap can help prevent extreme temperature fluctuations. A layer of mulch added to the top of the pot can also help insulate the roots and conserve moisture.
Before winterizing your hydrangea, it’s essential to trim away old wood and weak branches. Be cautious not to remove healthy wood, as it will be the source of new blooms in the next growing season. Pruning your hydrangea correctly helps with winter care and promotes healthy growth.
By following these winter care tips, your potted hydrangea will be well-prepared for a successful blooming season once warmer weather returns.
Troubleshooting Common Issues
If your potted hydrangea is struggling with health issues, don’t worry. By addressing these common problems, you can restore your plant’s health and keep it thriving.
Wilting can be a major concern for potted hydrangeas. This is often caused by either overwatering or underwatering. To tackle this, make sure the soil is consistently moist but not soggy. Be careful about how much water you give your plant, and ensure that the pot has proper drainage to avoid root rot.
Another issue you may encounter is the flower color, which can be influenced by the soil’s pH levels. For example, blue hydrangeas require more acidic soil, while pink hydrangeas need alkaline conditions. Test your soil’s pH and adjust it accordingly – using elemental sulfur to make it more acidic, or lime to make it more alkaline.
In addition, potted hydrangeas may suffer from insufficient sunlight. Ensure they receive at least 4-6 hours of sun exposure daily. Different types may have varying sun tolerance, so check the specific needs of your hydrangea.
Dealing with root rot can be challenging. This is often caused by poor drainage in the pot. To prevent this, choose a pot with proper drainage holes, and use a well-draining soil mix. If your hydrangea is already showing signs of root rot, it might be necessary to repot the plant, trimming away any decayed roots.
Proper care for your potted hydrangea is essential to prevent health issues. By being attentive to your plant’s watering needs, sunlight exposure, and soil conditions, you can keep your hydrangea thriving and looking beautiful.

Propagation
Hydrangeas can be easily propagated to create new plants for your pot. The best time to start propagating is during summer, when the stems are green and fleshy. Let’s dive into the simple steps to propagate hydrangeas through rooting a cutting.
First, make sure to choose a healthy 6-inch cutting from a soft hydrangea stem that doesn’t have a bloom yet 1. Use pruning shears or a garden knife to snip the cutting 2 inches below a pair of leaves, creating space for new roots.
Next, prepare your potting soil by mixing it with damp sterile potting soil or a soilless mix containing half peat moss and half perlite 2. Avoid using garden soil or soil rich in fertilizer, as excess nutrients might rot the cutting before it roots.
Now it’s time to plant your cutting. Remove the leaves from the lower half of the cutting, leaving only a couple of leaves near the top 3. This helps to minimize water loss and encourages rooting. You can also dip the cut end of the stem in rooting hormone to speed up the process, but this is optional.
Fill a 6-inch wide container with the prepared potting mix, and create a small hole for your cutting. Gently insert the cutting into the hole, firming the soil around it to hold it in place. Water the cutting thoroughly, ensuring the soil stays damp consistently until roots develop.
Place your potted cutting in a warm space with indirect sunlight. In a few weeks, you should see new growth, indicating that roots have formed. Once your hydrangea cutting is firmly rooted, you can transfer it to a larger pot or plant it in your garden.
By following these steps, you’ll soon have a new potted hydrangea to enjoy, adding more beauty and color to your outdoor space.
