Spade, twig cutter, pillar, watering pot with showerhead, slow release of nutrients, etc.
In April, once the earth begins to warm up again, take out the dahlia rhizome stored in the storage room (if purchased in the same year, try to select the healthy and fat root).
If there are too many tubers, you can divide them (use a small chopper to divide them) and pay attention to keep them on each rhizome - adventitious buds and some lateral roots.
Dig - about 20cm deep pit, loosen soil, remove big stones and grass roots. If the soil contains a large amount of sand, soil or compost should be used.
In order to provide the nutrition needed by Dahlia in the future, especially the nitrogen fertilizer, when hoeing the soil & nbsp; mix and release the slow fertilizer, pay attention to the application of fertilizer according to the proportion in the product description.
In order not to damage the root, before Dahlia takes root, set up the pillar in a pit about 15cm deep. Lay the bulb flat on the bottom of the pit, with the buds close to the pillars.
Fill the pit with broken soil. In order to make the ball root fully contact with the soil, gently step the pit with your feet, and then pour the pit through like a light rain.
In July, the dahlias planted in spring grow like mushrooms. It's time to set up pillars, if not at the time of planting. In order to cultivate large and beautiful flowers, it is suggested to cut them.
Before the roots are overwhelmed by the weight of leaves and flowers, set up a pillar at the foot of each dahlia. Be careful not to damage the ball root.
The prop should be 5cm away from the rhizome and tied loosely with plastic or coconut fiber rope. Be careful not to pull the roots and struts too tight.
In order to cultivate large flowers, the axils under the leaves should be eliminated with a sharp small branch cutter, and only the buds on the roots should be kept. At the same time, small lateral branches are eliminated.
The short Dahlia does not need to set up a pillar, and the clustered branches and leaves can support the flowers. However, in order to prevent bolting and reduce the burden of bulbs, it is necessary to eliminate the withered flowers in time. Timely elimination of withered flowers can also effectively promote the emergence of new buds.
In October, when Dahlia's flower season is out of date, use trimming scissors or sharp scissors to cut all roots and branches 10cm from the ground. Don't touch the leaves except the withered ones.
Wait until the plants have completely withered before pulling out the dahlia. If it is pulled too early, it may seriously damage its storage and affect future reproduction.
&When the plant is completely withered, use a long handled fork shovel to pull it out carefully and do not damage its root.
After air drying for several hours in the open air, remove the soil and dead leaves from the bulbs, cut off the redundant roots and branches (keep about 5cm), write down the product name and color, and fasten the label .
Store them in a wooden case in a dry and airy place. If you are afraid of erosion, store them in a net bag and hang them. Pay attention to regular observation of their health.
Where there is little frost and ice, leave Dahlia bulbs underground. Cut off all the withered branches and leaves 5cm from the ground. Cover with 20-30cm thick dry leaves or straw.
