Anthurium is a popular cut flower grown for its showy flowers and attractive foliage. It has bold, lasting flowers and is the second most traded tropical flower worldwide after orchids. Anthurium is mainly produced in India in the states of Karnataka, Kerala, and Tamil Nadu. There are many varieties that differ in spathe color and plant characteristics. Anthurium requires protected cultivation with specific soil, temperature, light, and humidity conditions. It is propagated through division, cuttings, or tissue culture and produces flowers on a spike that can be harvested and stored for weeks. Pests like aphids and diseases like black rot must be controlled through proper pest and disease management.

7. For pot culture
• Highly organic, well aerated with good water
retention capacity and drainage
• Soil, coarse sand, farm yard manure layer-wise.
• Media for pots should have:-
high porosity
low salt concentration
pH must be 5.5-6.5

8. For raised beds
• 4 inches brick pieces, 3 inches charcoal, 2 inches coconut husk
and small portion of coco peat & sand in 3: 1 ratio filled in the
beds one after another in layers. And finally planting is done.

convenience.
• Bed to bed: 50 cm

12. • Temperature: 180
C to 280
C
• Light: 75-80% shading is essential
• Relative humidity: 50-80%

13. • Foliar application of 1g urea + 2g MOP/ lit
ever week
• NPK 19:19:19 @ 2 gm/lit once a week

14. • Anthurium requires generous watering.
• Plants are to be watered twice daily during summer
months.
• Method of irrigation may be sprinkler, micro-
sprinkler, manual watering etc.

15. • Old and diseased leaf should be removed, but there
should be atleast 4-5 no. of leaves in the plant

16. • Most anthurium plants naturally produce small sucker
at the base of the plant. The suckers should be
removed at any stage.

17. • The maturity of the flowers for harvesting is
determined by the firmness of the peduncle and the
degree of colour of the spadix.
• Best time for harvest is when 1/3 to 2/3 of the flowers
on the spike are open.
• Harvesting in the morning time is preferrable

18. • After cutting above 3 cm, stalks are dipped in water
to prevent dry out.
• For distant markets the cut ends of each flower stem
should be wrapped with cotton pad soaked with water
covered with wax paper or polythene and secure tide.

19. • Soft protection material is put in between the spathe
and spadix of flowers with soaked cotton pads at the
cut ends. Foam plastic supports are provided in the
box and flowers are secured carefully with tape. The
spathe along with the spadix is then inserted into a
polythene cover of appropriate size and there after
placed in cartons. Lining of cartons with polythene
sheet and moist paper insulation are necessary to
maintain proper humidity as well as to prevent
injuries to the flower.

21. • Anthurium can easily be stored at 130
C for 2-3 weeks
and will last 2-4 weeks in an arrangement.
• Exposure of flowers to temperature below 130
C
causes the red flowers to turn blue, dark red flowers
being most succeptible.
Vase life
• Hydroxyquinoline resulted in additional bloom
opening of the flowers and also increase the vase life.

22. The Federations of Dutch Flower Auctions grading
specification for class-I flowers:-
• Absolute freshness
• Pest and disease free
• Fault free
• Stalks must be straight and significantly firm to carry the
influorescence
• Green petal margins are permitted

23. Pest management
• Aphids: can be controlled by Malathion or Rogor application
• Mealy bugs: can be controlled by Malathion

24. Disease
• Black rot: application of captan
• Leaf spot: application of captan or systemic fungicide.
• Bacterial blight: controlled by cutting off the infected
blossoms than sparying with fungicide like Captan or Thiram
