WaterDahlias, including the 'Grenadier', require a consistent watering schedule, especially during the growing season. Generally, they should be watered two to three times per week, making sure the soil is moist but not saturated. Depending on weather conditions, dahlias may need approximately 1 to 2 gallons of water each week. It's important to water at the base of the plant to keep the foliage dry and prevent fungal diseases. During hot, dry periods, additional watering may be necessary to maintain soil moisture.
LightDahlias like 'Grenadier' thrive in full sun exposure, which means they require at least 6 to 8 hours of direct sunlight per day. The best spot for these plants is in an area that receives unobstructed sunlight and is protected from strong winds. Partial shade is tolerable, especially in regions with extremely intense sun, but full sun is ideal for the healthiest blooms.
TemperatureThe 'Grenadier' dahlia prefers temperatures between 60 and 75 degrees Fahrenheit and can tolerate a range from just above freezing to about 90 degrees Fahrenheit. Dahlias are sensitive to frost, so it's critical to wait until the danger of frost has passed before planting them outdoors. They grow best in warm conditions with cooler night temperatures.
PruningPruning dahlias such as 'Grenadier' is essential for strong growth and vibrant blooms. Pinching off the main shoot after the plant has developed several sets of leaves will encourage bushier growth. Prune dead or damaged stems and spent flowers regularly to promote further blooming. The best time to prune is in late winter or early spring before new growth begins.
CleaningAs needed
SoilDahlias prefer well-draining soil with plentiful organic matter. A mixture of two parts garden soil, one part peat moss, and one part perlite works well for 'Grenadier' dahlias. The soil pH should be slightly acidic to neutral, between 6.5 and 7.0, to promote optimal growth and flowering.
RepottingDahlias, including 'Grenadier', typically do not need to be repotted as they are often grown as annuals. They should be planted each spring after the threat of frost has passed and dug up and stored during the winter in colder climates.
Humidity & MistingDahlias such as 'Grenadier' are adaptable to a wide range of humidity levels and do not require specific humidity conditions. Average ambient humidity is generally suitable for these plants.
Suitable locationsIndoor
Ensure bright light, moderate water, and good air circulation.
Outdoor

Life cycleDahlia 'Grenadier' (commonly known as Grenadier Dahlia) starts its life cycle as a tuber, which is planted in the ground in spring after the threat of frost has passed. The tuber sprouts and develops into a young plant, with foliage emerging from the soil and photosynthesis beginning. As the plant matures, it develops a robust stem and leaves, and eventually buds form. Following the formation of buds, the Grenadier Dahlia blooms in the summer to early fall, showcasing its vivid red flowers which attract pollinators. After the blooming period, the plant sets seeds, but gardeners often propagate Dahlias vegetatively via tuber division rather than by seed. With the onset of cooler temperatures and frost, the plant's aerial parts die back, and the tubers enter a period of dormancy over the winter, to be stored and replanted the next growing season.
PropogationPropogation time
Spring-Early Summer
Propogation: The Dahlia 'Grenadier', commonly known as Grenadier Dahlia, is often propagated during the spring when the danger of frost has passed. The most popular method of propagation for dahlias is by dividing the tubers. Each tuber, which is a swollen storage root, must have at least one "eye" or growth point from which the new plant will sprout. Before planting, these tubers can be cut using a sharp knife, making sure that each division has at least one healthy eye. The cut surfaces should be allowed to dry and callous over for a day or two to prevent rot. Plant the divided tubers in well-drained soil about 6 to 8 inches (15 to 20 centimeters) deep. Spacing between plants should be about 18 to 24 inches (approximately 45 to 60 centimeters) to ensure adequate room for growth.
