Here are the best flowers you can grow in India that bloom all year round
You can propagate dahlia from seeds or stem cutting, but we highly recommend you to get a well-grown plant from a nursery for a specific color and variety.
You can buy dahlia seeds from any local vendor and sow them in a potting mix from February to April. Water well and keep the pot where it can get bright, indirect sunlight.
To propagate dahlia from cutting, snip 4-5 inches shoots along with tuber. Remove the lower leaves, dip the end in a rooting hormone and plant it in a container with potting soil. Mist it slightly and place it in warm, indirect sunlight. The cutting will take around 4-6 weeks to develop shoots.
Growing Requirements of Dahlias
Dahlia performs best when nurtured with 4-6 hours of full sunlight. If growing indoors, a south or west-facing window will be the best. Dahlias appreciate morning sunlight, but save it from direct exposure to the scorching afternoon sun during summers.
As a thumb rule, water potted dahlias deeply when the topsoil looks dry. Avoid overwatering the plant as it may cause fungal diseases.
Most dahlias require at least a temperature above 13°C to bloom well. A range of 15-22° C is considered an ideal temperature range for thriving dahlia.
Dahlia loves well-draining and fertile soil that is slightly acidic to neutral with a pH of 6.5-7. For growing dahlia in containers, you should prefer a soilless potting mix. DIY it by mixing equal parts of fine bark, vermiculite, peat, and perlite. Alternatively, you can also blend equal parts compost, coarse sand, and coconut coir.
For growing dahlia in a container, choose an 8-12 inches pot with drainage holes at the bottom.
Use a low nitrogen, 5-10-10 fertilizer during the growing period every 4-5 weeks. They can also be fed with fertilizer designated especially for tomatoes. Avoid using high nitrogen fertilizer as it will result in more foliage and lesser blooms.
Pests and Diseases
Look out for snails, slugs, spider mites, and aphids. Use a neem oil solution to keep them at bay. Also, keep the area around the plant clean, deadhead spent flowers, and remove yellow foliage periodically. Prevent wetting the leaves as a precautionary measure.
