Royal Candles, also known as Veronica spicata, is a beautiful perennial plant with deep purple-blue flowers. It is a sun-loving plant that requires frequent irrigation and good drainage. Deadheading is an important part of its care, as it promotes continuous blooming and keeps the plant looking its best. Deadheading involves removing old, faded blooms to encourage new growth and can be done with hedge trimmers or by hand. Fertilizing after deadheading can also help to prompt more flowers. This process is an essential step in maintaining the health and aesthetics of the Royal Candles plant, ensuring its vibrant display throughout the growing season.

What You'll Learn
When to deadhead
Deadheading is the process of removing old blooms from a plant. It is recommended to deadhead Royal Candles Speedwell, also known as Veronica spicata Royal Candles, to encourage continuous blooming and to showcase the plant's dark green foliage.
So, when is the best time to deadhead Royal Candles? The ideal time to deadhead is when the blooms start to fade and turn brown, indicating that they are spent. This usually occurs in early summer, around June, when the plant produces its first blooms. By deadheading promptly, you can encourage the plant to produce more flowers later in the summer.
It is important to note that Royal Candles prefer full sun and well-drained soil. They are sun-loving plants that require frequent irrigation, allowing the soil to dry slightly between waterings. These conditions will help your Royal Candles thrive and promote healthy growth, making the timing of deadheading more apparent.
Additionally, keep an eye out for any pests or diseases that may affect your plant. Aphids, whiteflies, and thrips can occasionally become problematic, so it is essential to take preventive measures or treat them promptly. By maintaining the overall health of your Royal Candles, you will be able to easily identify when the blooms are spent and ready for deadheading.
In summary, the best time to deadhead Royal Candles is when the first blooms start to fade and turn brown in early summer. By deadheading at this time, you will encourage re-blooming and showcase the attractive dark green foliage of the plant.

How to deadhead
Deadheading is the process of removing old blooms from a plant. This encourages new growth and can improve the overall appearance of the plant. Here is a step-by-step guide on how to deadhead Royal Candles:
First, it is important to identify when to deadhead. Royal Candles are perennials that produce spikes of purple flowers in early summer, and sometimes beyond if deadheaded. The best time to deadhead is when the flowers start to fade and turn brown, usually in late spring to mid-summer.
Next, use hedge trimmers or gardening shears to cut the faded flower spikes back to a set of healthy leaves. Take care not to damage the healthy foliage while removing the spent blooms.
After deadheading, it is recommended to fertilize the plant to promote new flower growth. Royal Candles prefer a slightly acidic fertilizer with a pH of 5.5-6.2.
It is important to note that Royal Candles prefer full sun and well-drained soil. They are relatively low-maintenance plants and do not require much pruning beyond deadheading. With proper care, Royal Candles will provide a stunning display of deep purple-blue flower spikes throughout the growing season.
By following these steps, gardeners can effectively deadhead Royal Candles to encourage re-blooming and maintain the health and beauty of the plant.

How to identify spent blooms
Veronica spicata 'Royal Candles', commonly known as Spike Speedwell, is a beautiful addition to any garden. This bushy, upright, clump-forming perennial produces dense spikes of star-shaped, deep blue-purple flowers from early to late summer. To ensure continuous blooming and maintain the plant's health, it is essential to identify and remove spent blooms through a process called deadheading.
Identifying spent blooms on your Royal Candles is a straightforward task. Firstly, examine your plant closely for any visual indicators. Spent blooms will appear worn and faded, signalling the end of their life cycle. Look for discoloured or brown petals and a general lack of vibrancy compared to fresh blooms. The stems supporting these older flowers may also show signs of ageing, becoming dry, brittle, or bent.
Another way to identify spent blooms is to understand the growth habit of Royal Candles. This variety of Speedwell produces new flowers from the base upwards, meaning the oldest blooms will be found at the top of the spike. As the season progresses, the flowers at the base of the spike will gradually open, while the older blooms at the top will start to fade and wither. Therefore, by observing the progression of flowers from base to tip, you can identify the spent blooms.
Additionally, you can feel the spent blooms to confirm their condition. Gently touch the petals and check for any signs of softness or decay. Spent blooms may feel delicate and fragile compared to the firmer, more resilient texture of fresh flowers. This tactile inspection can help you further determine which blooms have reached the end of their lifespan.
By regularly inspecting your Royal Candles for these visual and tactile cues, you can easily identify spent blooms. Deadheading these older flowers will encourage the plant to redirect its energy into producing new blooms, ensuring a vibrant display throughout the season. Remember to use clean, sharp pruning shears to remove the spent blooms, making clean cuts at the base of the flower spike. With proper care and attention, your Royal Candles will thrive and provide a stunning display of colour in your garden.

Fertilising after deadheading
Deadheading is the process of removing spent blooms from a plant to encourage further growth. Royal Candles, also known as Veronica spicata Royal Candles or Royal Candles Speedwell, are a low-maintenance variety of Speedwell with upright "candles" of flowers throughout most of the summer. They are a clump-forming, bushy cultivar, often used in rock gardens, as a border plant, or in containers.
To encourage more flowers, it is recommended to fertilise Royal Candles after deadheading. Fertilising with a well-balanced, slow-release feed in the spring will help Speedwell multiply and spread vigorously. A diluted liquid feed once a month is also beneficial. For container-grown Royal Candles, regular watering and feeding are necessary.
If you are looking to force your Royal Candles to bloom out of season, there are a few things to keep in mind. Firstly, Veronicas have an obligate cold requirement to flower. Cuttings harvested from stock plants that have received a cold period will flower without needing an additional cold treatment. Cooling plugs or small containers of Royal Candles for a minimum of six weeks at 41°F will satisfy the cold requirement. After this, they will flower under any photoperiod. The time from vernalisation to bloom depends on the temperature—plants grown at 68°F will take eight weeks to flower, while those grown at 60°F will take 11 weeks.
To control pests such as aphids, which are the most common insect pest for Royal Candles, a preventative application of Marathon 60WP as a drench is recommended. This will ensure aphid-free plants from spring planting until shipping. Botrytis can also be an issue on the lower foliage where air movement is limited, and the foliage stays wet for extended periods. Powdery mildew and downy mildew may also be observed.

Watering and irrigation
Veronica spicata 'Royal Candles' (Spike Speedwell) is a sun-loving plant that requires regular watering and very good drainage. It performs best when grown in a moist, well-drained medium with a slightly acidic pH of 5.5-6.2. It is important to ensure consistent moisture along with sharp soil drainage.
To check if your Royal Candles plant needs water, simply touch the soil around the roots. If the soil is moist, there is no need to water. If it is dry, water the soil thoroughly with the hose end (no nozzle) without watering the leaves. Stick your finger about 3 inches into the soil to check its moisture content.
After the first season, water the plant only during extended periods without rain. Water newly planted Royal Candles as often as every 2-4 days at the start, and at least once a week for the first six weeks. Beyond this establishment period, water once per week unless it rains.
Royal Candles also require frequent irrigation. When irrigating, water thoroughly and then allow the soil to dry slightly before watering again.
