Shovel, branch cutter, prop, watering can with shower head, nutrient fertilizer slow-release agent, etc. In April, once the earth starts warming again, take out the roots of Dahlia stored in the storage room.

Remove the dried roots

If there are too many roots, you can divide them. Pay attention to keep adventitious buds and some lateral roots on each rhizome.

incision

Dig a pit about 20 cm deep, loosen the soil and remove big stones and weeds. If the soil has a high sand content, cultivate it with soil fertilizer or compost.

Adding base fertilizer

In order to provide nutrients for Dahlia, especially nitrogen fertilizer, slow-release fertilizer should be mixed while weeding, and the amount of fertilizer specified in the product description should be paid attention to.

Set up a pillar

In order not to damage the roots, stand the Dahlia before it takes root-the pillar is in a pit about 15 cm deep. Put the bulb flat at the bottom of the pit, and the bud is close to the post.

Watering after planting

Fill the pit with broken soil. In order to make the bulb fully contact with the soil, gently fill the pit with your feet, and then fill it thoroughly like a light rain.

decrease

In July, dahlias planted in spring grow like mushrooms. It's time to erect the pillars, if not during planting. In order to cultivate large and beautiful flowers, pruning is recommended. Before the roots are crushed by the weight of leaves and flowers, stand a pillar at the foot of each dahlia. Be careful not to break the light bulb.

Fixed bracket

The strut should be 5cm away from the rhizome, and the rhizome and strut should be loosely tied together with plastic or coconut fiber rope. Be careful not to pull the roots and posts too tightly.

short cut

In order to cultivate large flowers, the axils growing under the leaves are removed with a sharp twig cutter, leaving only the buds growing at the roots. At the same time, eliminate small side branches.

Prune dead flowers

Short dahlias don't need columns. Clusters of branches and leaves can grow flowers. However, in order to prevent bolting and reduce the burden on bulbs, attention should be paid to eliminating withered flowers in time. Eliminating withered flowers in time can also effectively promote the emergence of new buds.

orderly

10, when the Dahlia season is over, use pruning shears or sharp scissors to cut off all the roots and branches at 10 cm from the ground. Don't touch its leaves, except the withered ones.

Pull out dahlias

Wait until the plants are completely withered before pulling out dahlias. If it is pulled out too early, it may seriously damage its storage and affect its future reproduction.

Storage bulb

When the plant is completely withered, carefully pull it out with a long-handled fork shovel, taking care not to damage its roots. After drying in the air for several hours, remove the soil and dead leaves stuck to the bulbs, cut off the extra roots and branches, write down the names and colors, tie the labels, and store them in wooden boxes in dry and ventilated places. If you are afraid of erosion, you can store them in a net bag and hang them. Pay attention to their health regularly. In places where frost and freezing rarely occur, the bulbs of Dahlia can stay underground. Cut all withered branches and leaves from 5 cm above the ground. Cover with 20-30 cm thick dry leaves or straw.
