Selecting the Perfect Delphinium Stakes

Choosing the Right Material

Staking delphiniums begins with selecting the appropriate material for the task.

Bamboo Stakes: A Natural Choice

Bamboo stakes are an excellent choice for supporting delphiniums. They are sturdy, affordable, and blend seamlessly with the garden.

Metal Stakes: Durable and Long-lasting

Metal stakes, such as those made of aluminum or steel, offer durability and longevity. They are especially ideal for larger delphinium varieties.

Preparing Your Delphiniums for Staking

Timing is everything Staking should be done early in the growing season, ideally when the delphiniums are about 12 inches tall.

How to Stake Delphiniums

Gently Loosen the Soil Before staking, gently loosen the soil around the delphiniums to ensure easy insertion of stakes without damaging the roots.

Adjusting as They Grow

Delphiniums can grow  rapidly, so regularly check and adjust the stakes and ties as needed to prevent any constriction.

What is the best support for delphiniums?

Delphiniums are beautiful, tall, and elegant perennial flowers that require proper support to keep them upright and healthy. Here are some of the best methods for stake delphiniums in your garden:

Staking: One of the most popular ways to support delphiniums is via staking. You can use bamboo stakes or metal stakes to provide vertical support. Insert the stakes into the ground around the delphinium plant when it’s still young, being careful not to damage the roots. As the plant grows, tie it to the stakes using soft garden twine at regular intervals to prevent it from flopping over.

Caging: Another effective method is to use cages made of wire or plastic around the delphiniums. These cages can help keep the plant upright as it grows. Make sure the cage is tall enough to accommodate the full height of the mature delphinium.

Grid System: Create a grid system using stakes and horizontal strings or wires to support multiple delphinium plants in a row. This method provides support from all sides and helps prevent bending or breaking of the stems.

How to Stake Delphiniums

Companion Plants: Planting shorter, sturdy perennials or shrubs around your delphiniums can provide natural support. The neighboring plants can help shield the delphiniums from strong winds and provide additional support as they grow.

Pruning: Regular pruning can also help prevent delphiniums from becoming too top-heavy. Pinch back the growing tips when the plant reaches about 6 inches in height to encourage bushier growth. This may lessen the requirement for substantial support.

Mulching: Apply a layer of mulch around the base of the delphinium plant to help keep the soil moist and prevent the roots from drying out. Healthy roots contribute to a stronger stem structure.

Fertilization: Proper fertilization with a balanced, slow-release fertilizer can promote strong growth and robust stems, reducing the risk of flopping.

Watering: In order to maintain the health of delphiniums, adequate and regular watering is necessary. The stems may become more brittle and prone to bending in dry weather. Particularly during dry conditions, water deeply and frequently.

Windbreaks: If your garden is prone to strong winds, consider planting delphiniums near a windbreak, such as a fence or taller plants, to reduce the risk of stem damage.

Deadheading: Removing spent flowers (deadheading) can encourage new growth and additional blooming. It can also help reduce the weight of the plant, minimizing the chances of stems bending or breaking.

Remember that delphiniums can grow quite tall, and their heavy flower spikes can make them prone to toppling over or breaking, so providing the right support is crucial to enjoy their stunning blooms to the fullest. Tailor your support method based on your specific garden conditions and the size of your delphinium varieties.

Do delphiniums need to be staked?

Delphiniums, also known as larkspurs, are tall and elegant flowering plants that can benefit from staking, especially in windy or exposed garden areas. Staking delphiniums helps support their tall flower spikes, preventing them from bending or breaking under the weight of their blooms or from strong winds and heavy rain.

Here’s how to stake delphiniums effectively:

Choose the Right Stakes: Use sturdy stakes made of bamboo, metal, or wood. The stakes should be tall enough to reach at least the halfway point of your delphiniums’ expected height.

Insert Stakes Early: Place the stakes in the ground near the delphiniums while they are still young, ideally when they are about 12 inches (30 cm) tall. Avoid damaging the plant’s roots at all costs.

Tie Gently: As the delphiniums grow, gently tie them to the stakes using soft garden twine or plant ties. Avoid tying too tightly to allow some flexibility and prevent damage to the stems.

Additional Support: If you have a group of delphiniums or if they grow particularly tall, you may need to create a circular support structure around them using stakes and twine to help keep them upright.

Regular Monitoring: Check the ties and stakes throughout the growing season. Adjust them as needed to provide proper support and prevent any stems from leaning or breaking.

Staking your delphiniums will help them grow straight and tall, allowing their vibrant flowers to be showcased beautifully in your garden.

How do you tie delphiniums?

Tying delphiniums is a common practice in gardening to help these tall, delicate flowers stay upright and prevent them from flopping over, especially in windy or rainy conditions. Here’s how you can tie delphiniums:

Materials you’ll need:

Garden Twine: Use soft garden twine or stretchy plant ties to avoid damaging the stems.

Stakes: Wooden or metal stakes are commonly used to support delphiniums.

Scissors: To cut the twine.


Plant Support: Begin by setting up the support structure before your delphiniums grow too tall. You can place stakes around the delphiniums when they are still small or when they’re first planted. Insert the stakes into the ground a few inches away from the base of the delphinium plants.

Positioning: As your delphiniums grow, check their height regularly. When they reach about 12-18 inches (30-45 cm) tall, it’s time to start tying them.

Tying: Cut a length of garden twine, usually about 12-18 inches (30-45 cm) long, depending on the height of the delphiniums. Gently encircle the delphinium stems with the twine, just below the lowest flower spikes. Be careful not to tie it too tightly to avoid damaging the stems.


Securing to Stakes:  Next, secure the twine’s ends to the previously positioned stakes. Make sure the twine is taut but not too tight when you tie it to the stakes at a height that corresponds to the overall height of the delphiniums. To fasten the string to the stakes, use a simple knot or a loop.

Repeat as Needed: Continue to tie the delphiniums in this manner every 12-18 inches (30-45 cm) as they grow taller. Make sure the twine supports are evenly spaced to provide stability to the entire plant.

Regular Maintenance: Monitor your delphiniums throughout the growing season, and adjust the ties and stakes as necessary. As the plant continues to grow, you may need to add more ties higher up the stems.

By tying your delphiniums, you’ll help them maintain their beautiful, upright appearance and protect them from being bent or broken by strong winds or heavy rain. This practice not only enhances the aesthetics of your garden but also improves the overall health of the plants.


Can I reuse the stakes from last year?

Yes, you can reuse stakes if they are still in good condition. Clean them thoroughly before use to prevent any transfer of diseases.

Do all delphinium varieties require staking?

While not all delphiniums need staking, it’s a good practice for taller varieties to ensure their upright growth.

Should I stake delphiniums in containers?

Yes, even delphiniums in containers can benefit from staking, especially if they are tall or exposed to strong winds.

Can I use other materials for staking?

Certainly, as long as the materials are sturdy and safe for the plants, you can experiment with various options.

How often should I check the stakes?

Regularly inspect the stakes and ties, especially during periods of rapid growth, to prevent any damage to the delphiniums.

Can I stake delphiniums after they’ve grown too tall?

It’s best to stake delphiniums when they are still relatively young and manageable. Staking taller, fully grown plants can be challenging.

Final Thoughts:

Staking delphiniums is a vital skill for any gardener who wants to enjoy the beauty of these majestic flowers.
