And in colour as bright as your cheek.”

It is important to Cultivate Dahlia in soft soil which has sufficient amount of manure and good water drainage. The flowers must have the sunlight. At the time of blooming, compost should be used. For better results the compost should be applied in suspension form, adding just a little amount of Neem cakes is a must.
The Right Time for Sowing
Starting from March, Dahlia is sown by Planting method, till April in hilly areas whereas in the plains it is done starting from September and the planting stops in October.
Seed time for Dahlia in hilly areas starts from February and gets over by March while in plains the seed time is September-October. When the seedlings grow and gain a height of 2-3 inches, these are ready to be transferred at the desired place.
Cultivating Dahlia with Cuttings
Cuttings of the soft branches are planted in sandy soils. The roots grow faster if the cuttings are dipped a little in Seradex B liquid and planted in sandy soils. Once the roots grow properly, the plantlets can be relocated to the required place.
Growing Dahlia in Earthen Pots
Medium sized pots are suitable for Dahlia cultivation.
Preparing the Fillings for Pots
Loam Soil- 8 kgs, Leaf Manure- 5kgs, Dung Manure-8kgs, Super Phosphate- 50 gms, Murate of Potash- 25 gms, Limestone- 5-10 gms
Above said ingredients are mixed and the filling is prepared including Limestone 10 days earlier and kept aside, plantlets with healthy roots should be selected and planted in the mixed soil. Plantation is followed by light irrigation.
Supporting the Plants
Dahlia is a plant with green, tender stem and branches that is why it’s critical to provide required support. The plant should be tied along with a bamboo or wooden stick with the help of hemp.
Every branch bears 3 buds, if all the three are retained together, the size of the flower gets reduced therefore only the bud in the centre is reserved and the other two are plucked off.
Preserving the Condyle
When the Dahlia plant starts to wither, dig it out from the pot and cut the stem separate, leaving behind a 10 cms stem. The roots should be washed with water. Fill the pots with leaf manure and place these condyles i.e. the roots in it. Keeping the plants in cool , dry places is favourable for the plants.
It is necessary to protect the Dahlia plant from the disease named ‘Brown Spots’. As you seen the brown spots in Dahlia leaves start control measures immediately because this disease spreads rapidly in plants. Blitox solution of strength 0.5 gms/ltr should be spread on the leaves to get rid of brown spots.
An insect named Aphid, sucks the juice from Dahlia leaves which leads to wrinkling of the leaves. For the protection from these insects, a solution of 0.04 gms/ltr Malathion 50 E.C. is spread all over the plants. So get ready to give a warm welcome to these beautiful flowers, the gift of nature by planting it in your nursery.
