How to Care For Dahlias?

Dahlias are lovely spring and are moderately easy to cultivate. They make a great addition to any garden. They are sensitive to cold. They need full sun, so be sure to watch them closely, especially during the first stages of their growth.

Sunlight

Dahlias need at least 6-8 hours of sunlight per day. To avoid burning your plant, if you live in hotter areas, place them in partially shaded areas during peak afternoon hours.

Water

Dahlias are unlike other flowers in that they don’t require much water. Dahlias can survive in areas with plenty of summer rain. If not, water the plant deeply at least once or twice per week. The soil should always be moist. If the top layer of the soil appears dry, it is a sign that the plant needs water.

Temperature

The soil temperature is crucial for the healthy growth of dahlias. These flowers should be planted in temperatures at least 60 degrees F. (a metal thermometer can help you check). Remember that dahlias can struggle in cold soil (less 50degF), so wait until spring/early summer to plant them.

Toxicity

Although dahlias can be toxic to pets, they can cause vomiting and diarrhea. You should be careful where your dahlias are placed if you have curious pets.

Problems & Pests

Pests: Dahlias are prone to attracting thrips, caterpillars, and earwigs. Slugs love dahlias as they are small and tender. You might want to consider relocating your dahlias if you are experiencing a problem with slugs.

Problems: Dahlias can be susceptible to fungal diseases like powdery mildew, common in dry and warm climates. If your plants have white powdery spots on their leaves, this is a sign of fungal disease, either trim the affected areas or use a fungicide to treat it.

Repotting & Propagation

Repotting: The thickened, underground section of the stem should be repotted in the early spring, eight weeks before the last frost. This gives the plant advantage and allows it to produce full-sized, healthy flowers by summertime.

Propagation: Dahlias are possible to propagate from cuttings, seeds, and tubers. If you prefer to propagate using cuttings, make sure to cut off the lower set of leaves. Then place them in a pot with good drainage. The cutting will begin to take root in a few weeks if the soil is kept moist.

After you have mastered the basics, let’s discuss some additional tips and questions to make growing easier.
