All About Larkspur
Larkspur, scientifically known as Delphinium, is a genus of about 300 species of perennial flowering plants in the family Ranunculaceae. Native to the Northern Hemisphere and the African highlands, these plants are characterized by their vibrant, spike-like clusters of flowers in shades of blue, violet, and white.
Larkspurs flourish in cooler climates and are most commonly found in areas with low humidity. They prefer full sun to partial shade and are best grown in moist, well-draining soil. These flowers are often seen in cottage-style gardens, borders, and wildflower meadows due to their appealing height and striking colour.
When it comes to planting larkspur, it’s essential to know that these plants are sensitive to high temperatures. For this reason, they should be planted as early in the spring as possible to ensure they establish themselves before the summer heat kicks in. Moreover, due to the larkspur’s height, it is advisable to provide some form of support to keep them upright during windy periods.
Taking care of larkspur requires regular watering, especially during dry spells, but it’s crucial to avoid waterlogging the soil as this can lead to rot. To ensure the best blooms, use a balanced fertilizer once in early spring and then again after flowering. Note that while larkspur is a beautiful addition to any garden, it is poisonous if ingested, so it’s necessary to keep them out of reach of children and pets.
On a final note regarding pests and diseases, larkspur can be susceptible to powdery mildew, crown rot, and fungal leaf spots. Regularly inspecting your plants and applying appropriate treatments when necessary can keep these problems at bay, ensuring your larkspur flourishes and continues to provide vibrant colors year after year.

Larkspur Care Procedures
Successfully growing larkspurs requires a bit of planning and care. The following steps outline the basic procedures for planting, growing, and maintaining healthy larkspur plants.
Light and Temperature
Larkspurs are sun-loving blooms that thrive in bright, sunny locations. They prefer a minimum of six hours of direct sunlight per day. Although they can tolerate partial shade, too little sun can lead to weak, leggy plants and fewer flowers. Therefore, when deciding where to plant your larkspurs, choose a location that gets plenty of direct sunlight, especially in the morning.
As for temperature, larkspurs prefer cooler climates. They are spring-blooming flowers, and their growth can slow or even cease during the hot summer months. The ideal temperature range for growing larkspurs is between 50-65 degrees Fahrenheit (10-18 degrees Celsius). High temperatures can stress these plants, making them more susceptible to diseases. Therefore, in hot climates, it’s best to give larkspurs some afternoon shade to protect them from intensive heat.
When planting larkspurs, keep the temperature in mind. Since they are sensitive to heat, they should be sown as early in the spring as possible. This gives them enough time to establish themselves before the summer heat sets in. If you live in a region with very hot summers, consider planting your larkspurs in the autumn for bloom in the following spring.
In summary, to provide the best care for your larkspur, ensure that they get plenty of sunlight, and keep them cool. With the right mix of light and temperature, your larkspur will provide you with stunning blooms year after year.
Water and Humidity
Larkspurs have moderate water needs. It’s essential to keep the soil evenly moist, particularly during the growing season, but be careful not to overwater. While larkspurs appreciate consistent moisture, they do not tolerate waterlogged soils, which can lead to root rot, a common larkspur disease. Implementing a regular watering schedule is key; early morning is the ideal time to water larkspurs, as this allows excess water on the leaves to evaporate throughout the day, preventing the onset of mildew.
As seedlings, larkspurs need to be kept consistently moist until they are well established. Once they have matured, larkspurs are relatively drought-tolerant but will still need regular watering in the absence of rainfall. For mature plants, a good rule of thumb is to water deeply once a week, or more frequently during hot, dry periods. Always water at the base of the plant to avoid getting the foliage wet and minimize the risk of fungal diseases.
Regarding humidity, larkspurs are relatively flexible and can adapt to various humidity levels. However, maintaining good air circulation around the plants can help prevent powdery mildew and other diseases. Regularly inspect your plants, especially during damp, humid conditions. If you notice any signs of disease, treat promptly with an appropriate fungicide.
In summary, when it comes to water and humidity, the key to healthy larkspurs is balance. Keep the soil consistently moist, ensure good air circulation, and vigilantly watch for signs of disease. With these steps, your larkspur plants will flourish, providing stunning blooms throughout the growing season.
Soil and pH
Larkspurs are relatively flexible when it comes to soil types, but they do perform best in rich, well-draining soil. Loamy or sandy soils are ideal, as they allow for good water drainage and prevent the roots from becoming waterlogged. If your garden has heavier clay soil, consider amending it with organic matter to improve its texture and drainage capabilities.
In terms of pH, larkspurs prefer slightly alkaline conditions. The optimal pH range for these plants is between 6.5 and 7.5. Before planting, it is a good idea to test your soil’s pH, which can be done using a home test kit or by sending a sample to a laboratory.
If your soil is too acidic (below 6.5), you may need to add lime to raise the pH level. On the other hand, if your soil is too alkaline (above 7.5), it can be lowered by adding sulfur or organic matter like compost or manure. Remember that changing soil pH is a gradual process and should be done carefully to avoid damaging the plants.
Preparing Soil
Preparing the soil for larkspurs begins with clearing the planting area of any weeds or debris. Then, dig a hole that is twice as wide and the same depth as the size of the root ball.
Before planting, improve your soil by mixing in some organic matter, like well-rotted manure or compost, which will enrich the soil with nutrients and improve its drainage. If your soil is heavy clay, you might also consider adding some horticultural grit to the mix.
Once you have prepared the hole and enriched the soil, place the larkspur into the hole, ensuring that the top of the root ball is level with the soil surface. Backfill the hole with the amended soil, firming it gently around the base of the plant. Water thoroughly after planting.
In summary, the best soil for larkspurs is loamy or sandy, slightly alkaline, and rich in organic matter. By taking the time to prepare your soil properly, you can create an optimal growing environment for your larkspurs, ensuring a healthy plant that produces beautiful, vibrant flowers.
Fertilizer Care Procedures
Larkspurs can benefit greatly from regular fertilization, aiding their growth and enhancing their beautiful blooms. However, care must be taken to avoid over-fertilization, which can lead to excessive leaf growth at the expense of flowers.
Start the fertilization process as soon as the larkspur plants are established and begin actively growing. Use a balanced fertilizer, with an N-P-K ratio of 10-10-10, which means it contains an equal proportion of Nitrogen, Phosphorous, and Potassium. These three elements are essential for the plant’s overall health and flowering.
To fertilize, scatter the granular fertilizer evenly around the base of the plants, but take care not to let the granules come into contact with the plant stems or leaves as this can potentially cause burns. Generally, a cup of fertilizer is sufficient for every 20 square feet of planting area.
After applying the fertilizer, water the area thoroughly. This will help dissolve the fertilizer granules and carry the nutrients down into the root zone where they can be absorbed by the plants.
Repeat this fertilization process every 4-6 weeks during the growing season, typically from spring until late summer. However, stop fertilizing about a month before the first expected frost to help the plants prepare for winter.
Remember to also maintain the other aspects of larkspur care alongside regular fertilization. This includes providing adequate light, maintaining the right temperature, ensuring the soil is well-drained and slightly alkaline, and keeping the plants sufficiently watered but not waterlogged.
In summary, proper fertilization is a crucial part of larkspur care. With the right balance of nutrients, combined with appropriate care, your larkspurs will reward you with lush growth and spectacular blooms.
Repotting Care Procedures
Repotting larkspurs allows them to continue growing healthily and vigorously, and is an important part of their overall care. Here’s a step-by-step guide to repotting your larkspur plants:
1. Choosing the right time: The best time to repot larkspur plants is in the early spring, just before the new growth starts. This allows the plants to quickly recover from the stress of repotting as they enter their active growing phase.
2. Selecting a new pot: When choosing a new pot for your larkspur, select one that is one size larger than the current pot. The pot should also have adequate drainage holes to prevent waterlogging.
3. Preparing the pot: Fill the new pot about one-third full with fresh, well-draining potting soil. You can make your own mix using equal parts of compost, coarse sand, and loamy garden soil.
4. Removing the larkspur: Carefully remove the larkspur from its current pot. To do this, gently tip the pot on its side and slide the plant out, making sure not to pull on the stems. If the plant is stuck, tap the edges of the pot to loosen the soil and roots.
5. Placing the plant: Place the larkspur in the new pot, positioning it so that the top of the root ball is about 1 inch below the rim of the pot. It’s important to ensure that the plant is sitting at the same depth as it was in the previous pot.
6. Adding soil: Fill in the space around the root ball with potting soil, pressing it down lightly as you go. Leave about a 1-inch space between the soil surface and the rim of the pot for watering.
7. Post-repotting care: Water the repotted larkspur thoroughly and place it in a location where it will receive indirect sunlight for a few days. Once the plant has adjusted to its new pot, you can move it back to its normal location.
In summary, regular repotting is an important part of larkspur care. With careful attention to the timing, the selection of a new pot, and the repotting process itself, you can ensure that your larkspur continues to grow and thrive.
