How much sun do Cafe au Lait dahlias require?
Light/Watering Dahlias are at their best when grown in full sun in the North, and afternoon shade in the South. Do not water until growth appears above the ground; once plants are established, a deep watering twice a week will get them through summer dry periods. Once the dahlias are above the ground and established, they will require deep watering 3-4 times per week for 60+ minutes by sprinkler or soaker hose, and even longer in the heat of the summer. In containers you will need to be watering 1 – 2 times per day until the water runs out the bottom of the container.Dahlias grow best when they receive a consistent supply of water. Drip irrigation is ideal, as it directs moisture to the root zone while keeping the foliage dry. If you are hand-watering, it’s best to water deeply once or twice per week.Planting tubers the wrong way is another common mistake. To grow strong roots and healthy stems, dahlias need to be planted at the right depth and in the correct position,” says Vasylchyshyna. Simply place each tuber horizontally in a hole about 5 to 6 inches deep, with the small growth bud facing upward.Dahlias can thrive in pots just as they do in the ground, but you have to be vigilant with watering, feeding, and it’s best to choose a cultivar that suits the size of your pot.
