this plant more popular. Follow the below tips for successful growing.
Propagation
Petunia is propagated
from seeds as well as cuttings. Petunia
likes warm weather so sow seeds in warm months to increase odds of
success. March – April will be good for
starting Petunia. Petunia seeds are very small so one need to take extra
efforts while sowing. Prepare potting
mix/ soil before sowing the seeds. Water the container / Pot thoroughly and
allow it to drain. Sprinkle seeds on well drained soil and gently push them
down. Do not cover Petunia seeds with
soil as they need light to germinate.
Seedlings will come out within two weeks in warm climate.
Or take softwood ( not
matured , green stem ) cuttings in spring or summer. Remove most of leaves but
2 leaves on the top. Remove all the buds as they drain all the energy. Push
cuttings down in soil / Potting mix. Cover the container having cuttings with
plastic bag to save moisture for plant. Moist the soil if it dry out.
Container
You can use small sized
container as Petunia are low grower. It doesn’t need much space to grow. Make sure container is having drainage holes
for better drainage space.
Soil
Use normal purpose
garden soil enriched with good quality compost.
Light sandy soil is ideal. Petunia like neutral to slightly acidic soil
( pH 6.0 – 7.0 ).
Sun
/ Temperature
Petunia like warm
weather and thrives in full sun. Also
grow in partial shade but bloom in less number. So keep the container in the
sunny location.
Watering
Keep soil moist. Allow
soil to dry out between waterings. When leaves get droop, water the plant,
after watering Petunia will be again standing straight. Do not overwater as it
will induce root rot and invite bacterial and fungus infection.
Fertilizer
Use a liquid fertilizer once in a month and every
two weeks for heavy feeder varieties.

Jai, nice to read your article. I have tried to grow petunias for the first time in pots. Since past one month, however, its been a struggle. They had flowers for a while, but suddenly, all of the plants stopped flowering around December. Now all I could see was green leaves. I cut back most of the stems to 1/3rd, to encourage fresh growth. But the new growth seems a bit slower. When will they recover in growth and what should I do to get them to flower again?
ReplyDeleteHi, Dear friend, the reason behind not flowering could be less sun light and low temperature in winter as petunia blooms in warm and bright location so kindly relocate petunia to a warm and sunny place if you are growing in a container. If it doesn’t help then feed petunia with a potassium based fertilizer or give liquid fertilizer diluted in water available for flowering in market.
ReplyDeleteYou have also mentioned about pruning so be patient as pruning will definitely result in new growth as well as new blooms in 2-3 weeks most probably.
Hi,do we need to cover the pot with plastic sheet after the seeding.Do we need to cut holes for air circulation?
