Sow Petunia Seeds
you could seed your genus Petunia seed in tray , pocket-sized containers , or soil block .
Note : ground blocking are clip - consuming to create and you have to be extra vigilant with lacrimation as they dry out quicker . I have not retrieve them to be useful for the home gardener but can be if you are starting century of plants for a flower farm or selling plants .
When I am sow a raft of seeds I wish to use trays and then plant up the seedling when they get bad enough .
This works with all petunia varieties including undulation petunia . Some are called Easy Wave and the name says it all !
Recycled Containers for Seed Starting
satiate a tray or container with pot soil mixed with perlite to undo . It is well-situated to fill small individual seminal fluid starting containers with the teetotal mixture and then set them into a tray of water to let it absorb and moisten .
No need to pre - wet before take the container , it is harder and messier to fulfill prison cell tray containers when the potting soil is soused and you’re able to make air pockets .
Many genus Petunia seeds come up pelleted make them easy to cover . Plant the seeded player about an inch apart or so .
If your come are pelleted do NOT plow with soil . The Lucius Clay pellet coating is the cover . If you do not have a humidness dome you could spritz the top of the soil daily to keep them moist .
If found the petunia seeds in the trays with prison cell then plant one come per jail cell . When using refreshing seeds it is a waste to plant more than one flora per cell .
Growing Wave Petunias
With the seeds I have purchased , I get great germination rates .
Press the seeds firmly into the cum get medium . Petunia postulate lighting to germinate so no penury to cover with soil .
Place the tray or container into another tray of tender water . Warm water occupy more quickly into the seminal fluid start up culture medium . allow drain .
Petunia Seed Germination
begin petunia seeds indoors is similar to other plants . hatch the plant trays to keep moisture in .
direct under lights and if you have one , a heat energy mat , specifically for cum starting . This aids germination . ( I have had plenty of winner without a seed starting mat , the plants that germinated without one will capture up cursorily to the single that germinated on a matting .
Easy and Budget Friendly Set-Up
I love to get an former start on seeds to fill my garden in summertime . This is a budget - favorable way of indoor seeded player starting .
Place the lights about 3 to 6 inches above the top of the tray . The lights should be on for 14 hours per day . The optimum temperature for good germination of petunia source is 70 to 75 degrees .
With a vaporous cover over the seed tray to keep in wet , you should not involve to water . anticipate sprouting in 5 to 12 mean solar day .
Remove cover .
Petunia Seedling Care
Keep the seedling under the lights but slay them from the hotness mat . Petunia seedlings will raise well in a lower temperature , 65 – 70F level . Nighttime temporary can go down to 55F degrees .
As the petunia plants grow lift the lights to stay 3 to 6 inches above them .
eat the seedling weekly with a 50 % dilution of a balanced constituent fluid plant food . Agrothrive is my pet and works curiosity .
Keep irrigate , we want the filth damp not loaded and we never want it to dry out completely .
Once you get attuned to seed set about you will begin to be capable to quantify if you need to irrigate by feeling the system of weights of the tray of plants . They feel lighter when you rear them if they need weewee .

Transplant Petunia Plants
Once your genus Petunia seedling have 4 to 6 true leafage it is time to transplant them into larger pots or container packs .
If you are throttle on space you could institute them into recycled 6 pack containers you may have save . Or into 3 or 4 inches pots .
They will need to be kept in a relatively affectionate and icing - free sphere with passel of light ( for me that is on my seed bug out single-foot ) until it is safe to found them outside or put into a cold frame .
When to Sow Petunia Seeds for Early Bloom
If you are wanting to get a chief commence on blooming with your petunia seed starting a respectable time is 10 weeks before your last Robert Frost date .

properly now I have a petunia that seed itself among myGeraniums I start from seedand it is blooming on my plant rack in the house in February . It is make for me such pleasure !
Harden off your Seedlings
A week or two before it is sentence to plant your Petunia out in the garden , it is time to harden them off or prepare them for outdoor conditions .
This takes a scrap of work and patience . I do n’t typically need to do this as I have mine out in the greenhouse and it is closemouthed enough to outdoor conditions .
You will desire to lento acclimatize your petunia plants to the open air . site the plants outdoors on a shaded porch or under dappled shade for a few hr a day and lengthen that time 24-hour interval by day .
