GERMINATION AND GROWING DETAILS

1.The seeds of trumpet flower (Incarvillea pants) should be sown on the surface either before the last frost of spring or in the autumn. Incarvillea members like to grow in the sunny area of the garden, and will not tolerate high humidity. Trumpet flowers have a preference for soils that are of a sandy nature, with a slightly acidic rich growth medium.

2.To grow first the Incarvillea indoors then they should be started about two months before the expected last frost of spring. They will take about three to eight weeks to germinate at a temperature of 15 to 21 degrees Celsius. Once the trumpet flower (Incarvillea) seedlings transplant them at 25 cm (small species) to 50 cm apart (large).

3.Hardy Gloxinia plants are somewhat difficult to divide due to their long taproots, but when necessary they can be carefully divided in the spring, immediately after flowering.
Offsets that emerge from the base of the plant can be removed and treated as softwood cutting.

4.Hardy Gloxinia seeds require light for germination so do not cover them.

Step 1

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

Step 2

Put the seeds over it by 1/3 after that cover the seeds with seedling mix only about 1centimeter.

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.

Step 5

Thereafter spread the mixture on the Incarvellea seeds. If the 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.

Step 6

Cover tightly plastic polythene over the pot to control 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.

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.

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 it is required. Place the container in a semi shaded place. Incarvellea needs a proper sunny area to germinate.
