Tips on How to Grow Petunias

Light: Light is necessary for germination. Provide a light source of 10 � 100 foot candles (100 � 1000 lux) if utilizing a chamber.
Moisture: Saturated (5) for days 1 � 3. On days 4 � 6 reduce moisture to wet (4). Reduce further beginning day 7 to medium Humidity: 100% until radicle emergence then reduce to 40%.
Dehumidify: Provide horizontal airflow to aid in drying down the media through evapotranspiration, allowing better penetration of oxygen to the roots.

Temperature: 72� � 76�F (22� � 24�C) until radicle emergence. Gradually reduce to 62� � 65�F (16� � 19�C) as cotyledons expand.
Finish Bulking/Flower Initiation � Optimum conditions during the vegetative period, beginning at transplant, needed for the root to reach the edge of the container; AND to make the plant receptive to flower initiation.
Media: pH: 5.5 � 5.8 Yellow upper leaves may indicate iron deficiencies when pH is > 6.6.

Light: Petunias need long days to flower. To initiate bud under short days, extend day length to 13 hours. Under long day, low light conditions, supplemental lighting of 350 � 500 foot candles (3500 � 5000 lux) may be necessary.
Temperature: After transplant, Petunias require temperatures > 55�F (13�C) nights for the first 6 weeks to initiate flower bud development.
After bud set, the night temperatures can be lowered to 50�F (10�C) to encourage basal branching and compactness.
However, lower temperatures may also substantially decrease the number of flowers initiated. Downward cupping of leaves may indicate too cool temperatures in combination with overwatering.
Average Daily Temperature (ADT): 67�F (19�C)
Moisture: Alternate between moisture levels wet and dry Allow media to dry before re-saturating to level .
Dehumidify: Provide horizontal airflow to aid in drying down the media through evapotranspiration under cool, low light conditions.
Fertilizers: Under high light conditions, apply an ammonium-based feed (17-5- 17). Under low light conditions, apply a calcium-based feed (14-4-14). Under high light and long or extended days, an ammonium-based feed (20-10-20) is preferred. To prevent stretching under low light and cool temperatures, reduce ammonium and apply only calcium-based fertilizer.

Pick Your Type of Petunia

Grandifloras
Grandifloras are one of the oldest varieties. These petunias grow eight to twelve inches high and have the large (4-5"), wavy-edged blossoms that petunias first became known for. They can be single or double. Grandiflor petunias have the largest flowers, but the flowers get pummeled by rain and are unpleasant to deadhead. However some of them, like 'Prism Sunsine' are stunning. Grandifloras work well in both beds and containers.

Multiflora
Multiflora petunias have a more compact growth habit than grandifloras. The flowers are smaller (2"), but more prolific and they hold up better against rain. There is also a wide range of colors. Multiflora petunias are a better choice for garden beds and also work well in containers. Hybrids of grandiflora and multiflora petunias often share qualities.

Milliflora
And now for something completely different! Whereas plant breeding is often aimed at producing bigger and better plants bearing bigger and better flowers, this new variety has concentrated on the reverse. At little more than a third the size of your average Petunia plant, this quite charming plant makes up - if that were necessary - for lack of stature by covering itself with countless flowers, each about 1� ins. across, all summer long. These delightful flowers, without doubt Petunias, are just charming, scaled-down versions of their more usual relatives but still manage to conceal the foliage beneath their abundance.

Spreading
The Spreading types created quite a stir when first introduced and keeps improving. 'These petunias grow only 6" tall but can spread to 4' wide. They make wonderful groundcovers and trailers for containers. Although Spreading petunias do not need deadheading, they do wear out in the hottest part of the summer and some pruning will revive them.
