FAQs

Topmix dahlias are a type of dahlia plant that is lower growing than Mignon types, but with even more flowers that are just over 1 inch in size. They are known for their vibrant colors and prolific blooming, attracting lots of butterflies and bees. At Dutch Flower Bulbs we offer Topmix dahlias in the following colors: pink, red, white and yellow.

Their bushy, low-growing habit makes them ideal for use in borders, pots, and containers. These dahlias are easy to grow and care for, making them a popular choice for gardeners who want to add color and texture to their outdoor spaces.

The best way to plant Topmix Yellow dahlias is to choose a location with well-draining soil and full sun exposure. Plant the tubers about 4-5 inches deep and 12 inches apart, with the "eye" or growing point facing up.

Water the soil well after planting and keep it moist but not waterlogged throughout the growing season. Add a layer of organic mulch to help retain moisture and suppress weeds. Fertilize the dahlias with a balanced fertilizer once a month during the growing season.

Pinch off the first set of buds to encourage bushier growth and more flowers. Topmix Yellow dahlias don’t need staking because they are low-growing dahlias.

To keep Topmix Yellow dahlias blooming, there are a few key things to keep in mind. First, it's important to plant them after the last frost date has passed. Dahlias are in the northern regions not winter hardy at all, except for warmer climates such as in USDA zones 8 or higher.

Secondly, plant them in well-draining soil and in an area with full sun (at least 6 hours). They also benefit from regular watering and fertilization throughout the growing season. Deadheading the spent blooms will encourage the plant to produce more flowers, and cutting the flowers for bouquets can also help promote further growth.

Additionally, it's important to protect the plants from pests and diseases, which can damage or kill the flowers. With proper care and attention, Topmix Yellow dahlias can provide beautiful blooms throughout the growing season.

Good news, they can multiply, but as a gardener you need to help. To encourage multiplication, it is recommended that you divide the tubers and replant them every few years. This will help to keep the plant healthy, promote better blooms, and increase the overall size of your Dahlia patch.

It is a simple process that can be done in just a few steps. This can be done in spring, when new growth has started to emerge, but also in fall after blooming time.

To divide a dahlia, carefully dig up the plant and separate the tubers, making sure each section has a few healthy eyes (the small bumps on the surface of the tuber from which new shoots will emerge). Plant each section in a new location, taking care to give it plenty of sunlight and well-draining soil.

With proper care, each divided section should grow into a new dahlia plant, resulting in the multiplication of the original Topmix Yellow dahlias.
