GERMINATION GUIDE

 

Most important:Avoid Rainy day or a cloudy weather for sowing the seeds.
You will definitely get nothing unless you wait for the bright Sunny day and clear weather.


GERMINATION GUIDE

Use a flat seedling tray and its deep will be 10 centimeter, and fill  seedling mediato within 3/4  of the rim with a sterile potting soil or sieved vermicompost . Fill the tray with diluted fungicide water (2gm in 1 liter water) . Make sure you have plenty of holes in it for good water drainage. And  Allow the soil in the flat to absorb the water through the bottom drainage holes until the soil surface becomes moist.



Soak the Thunbergia seeds over night in tepid water. Following the soaking, sow Black-eyed Susan vine seeds outdoors after the last frost in prepared seed bed Or  on the growing season, sow Thunbergia Alata seeds indoors 6 - 8 weeks before outdoor planting. Seeds will germinate in 7 to 21 days and flowering takes anywhere from 6 to 9 weeks depending upon pot size.



Sow seeds on the soil surface  apart 1 to  2 inchs. Press on the seeds lightly with your fingers so they are in full contact with the soil, but don't cover them with soil because they require light to germinate.Place  the seedling  tray at room temperature (70-75F) in a bright window.
Moist again with diluted fungicide water ensure the  soil surface it's evenly moist. Thunbergia flower seeds germinate better in darkness.

 The Thanbergia usually sprout within seven to 10 days.Remove the plastic as soon as the seedlings emerge, and gradually move the pot to a brighter area with six to eight hours of daily sunlight for  two-week period so that at the end of that time they're acclimated to being in full sunlight. Water the seedlings when the soil surface feels dry.



Transplant the Thanbergia outdoors or in a new pot when they are about 8 weeks old and about 4 to 6 inches tall. Plant at the them 8 to 14 inches apart on ready ground with same depth  were they  growing at previously.



Sow Outdoors: Surface. Following the last frost. Spacing 4 to 24 inches (10 to 60 cm).




CLIMATE:

Thunbergia can be grown in heardness zone 6-10, although in zone 6 they’re likely to die back to the ground in winter.

WATER:

Thunbergia like humid climates. Once established, they can tolerate quite a bit of drought.

LIGHT:

Thunbergia flower best in full sun (at least six hours per day).

SOIL:

Thunbergias do well in most any kind of soil, as long as it’s well-drained. The ideal soil pH is neutral to slightly acidic.
