You might need to provide some of the taller varieties with a stake if they look like they are going to fall over. We recommend that you prune the plants back every now and again as this will promote new growth. You can maximize the size of the flower by reducing the size of the two buds next to it – allowing the central one to grow alone.
If you notice deformed/stunted growth or mottled foliage, the plant has been infected and should be discarded as soon as possible.
If you want to put the flowers in a vase, cut them in the morning – this will allow the stems to dry up in the heat of the day. Ensure that you cut the flowers just before they are about to bloom. As the season ends, the leaves of the plant may turn yellow, you can cut and break these leaves away.
If you would like to lift Dahlia, do it at the beginning of winter. Cut the stem roughly 5cm above the ground. You can then lift the tuberous root. If they were well fed, there should be an increase in the size and quantity of tubers around the crown. Do not wet the roots during this time.
Large crowns can be split as long as they each contain one old stem. You can also take cuttings from younger plants in the early summer.
