DEFINITION

The flowers are large, with four spreading scarlet or orange-red petals up to 8 cm long, and a fifth upright petal called the standard, which is slightly larger and spotted with yellow and white. The naturally occurring variety flavida has yellow flowers.Seed pods are dark brown and can be up to 60 cm long and 5 cm wide; the individual seeds, however, are small, weighing around 0.4 g on average. The compound leaves have a feathery appearance and are a characteristic light, bright green. They are doubly pinnate: Each leaf is 30–50 cm long and has 20 to 40 pairs of primary leaflets or pinnae on it, and each of these is further divided into 10-20 pairs of secondary leaflets or pinnules.

GERMINATION

Use a flat tray container about 10 inches by 15 inches (biggest or smaller your choice) 1.5 to 2 inches deep. Make sure you have plenty of holes in it for good water drainage è put the seedling mix you prepared up to almost top leaving about 0.5 inches space- now evenly spread the seeds over it after that cover the seeds with seedling mix only about 0.5 cm (half centimeter) - water it by watering can- place the container in semi-shaded place.

Step 1
Use a flat seedling tray and its deep will be 5 centimetres. Make sure you have plenty of holes in it for good water drainage.

Step 2
As the seeds are  perfect in size then you can put the seeds over it by 1/3 after that cover the seeds with seedling mix only about 1 cm (one centimetre)

Step 3
Take equal quantity of sand, soil and vermicompost. Then mix all the three ingredients into one container.

Step 4
Sprinkle diluted fungicide water (2gm in 1-litre water) after sowing the seeds.We have to care about putting the seed because seeds will not go deep into the mixture.

Step 5
Thereafter spread the Gulmohor seeds in the mixture. If your seeds are so tiny then you can spread water very lightly and carefully on the seed.Make sure that the water must be mixed with diluted fungicide powder.It is very important to notice to follow that the seeds will not to go very deep inside the mixture by speeding water on the seed if it happens then the fertilization of the seeds become difficult.

Step 6
Cover tightly plastic polythene wrap over the pot to promote soil moisture retention and place it in a dimly lit area of the house. Lift the plastic daily to check that the soil is moist. If not, lightly moisten it with a water-filled spray bottle before replacing the plastic. Expect germination within three to five days.

Step 7
Remove the plastic as soon as the seedlings emerge, and gradually move the pot to a brighter area over a two-week period so that at the end of that time they're acclimated to being in full sunlight.

Step 8
Minimum warm, above 60ºF (15.5ºC), is needed inside the container and it should be placed in the sunny area.After that, the whole thing should be covered with a poly bag and after 21 days later the plastic can be removed.

Step 9
Watering as required. Place the container in a semi shaded place. Gulmohar needs a proper sunny area to germinate it.

IMPORTANT WATERING USE: Use watering can for watering. By moving the water stream constantly waves the can. Do not let the water to flood in particular area. Or use the sprayer to spray the water like mist.
