How to Plant Penhill Watermelon Dahlia Bulbs
When to Plant Dahlia Bulbs
Unlike other bulbs such as Tulips, Dahlias like warm soils so plant Dahlia bulbs during the warmer and longer days of spring. Dahlias are usually planted about the same time you would plant your vegetable patch. Dahlia bulbs can be planted as late as mid-June in most parts of the country.
Where to Plant Dahlia Bulbs
Dahlias will thrive in full sun but can tolerate some partial shade - the more sun, the bigger the flowers. Try to select a location that receives at least 6 hours of sun, sheltered from the wind and with, and this is vital, good drainage.
How to Plant Dahlia Bulbs
Dig a hole twice as deep and wide as the Dahlia bulb. Put the tuber in the hole with the “eye” on the tuber facing up. The eye is the point on the shoulder, or crown, of the tuber from which the plant grows. If you are planting a number of dahlias in the same location, they should be separated by about 2 feet to give each plant room to grow. The shorter varieties can be planted closer together. Plan for the rows to be 3 to 5 feet apart depending on the size of the plant. Fill in with soil to just cover the top of the bulb. As you begin to see new growth appear, cover again with soil. Covering the stem gradually will allow the stem to strengthen so it can support the flowers. Unless it is a very dry spring, it is not be necessary to water at the time of planting. The tubers will begin growing with the warmth and moisture in the soil. It is vital that they form a root system early in their planted life to assure a strong and healthy plant. Watering at the time of planting may encourage rot but as soon as your Dahlias are growing above the ground, water deeply to encourage strong roots.
How to Care for Dahlia Bulbs
Young dahlia plants do not need a lot of water, excessive water can lead to rotting of the plant. For larger plants, a good rule of thumb is to water if the rainfall is less than one inch in seven days. Pots require more regular watering. As the plant grows, remove any broken or damaged foliage. Good air circulation, especially near the ground is needed by the plants to prevent powdery mildew. Once the plants are several feet high the lower leaves can be removed to increase air circulation. Your dahlias will continue to bloom prolifically right up until frost. A heavy frost will kill the plant so you may want to dig the half a dozen or more tubers the plant has produced. Those tubers can then be stored and grown next spring!

Strong and Prolific Plant
I wanted to try this plant last year, so i bought it during the sale, knowing that I was planting it late and would not get as many flowers, but it was worth a try. It never bloomed at all, but was in good shape when going into dormancy, so I waited. This year it came through for me and is a tall, stately plant in my cutting garden; so tall I took very long, first cuttings to balance it out a bit with neighboring dahlias. The flowers were nodding toward the ground, like sunflowers and I agree that they would be perfectly placed in the back of a border.
I have only one complaint. The color isn't similar to any of the photos, but darker and each flower is less varied in color than these photos indicate. Still they make a big impression in a floral arrangement.

Huge, showy blooms for late summer
I usually choose a couple new varieties every year, and this was my pick for 2019. Upright growth (not bushy at all) with very large blooms that followed one after the other. Neighbors would often stop to comment. Recommend for back of your dahlia garden.
