The fact
Video of the Day
Petunias are yearly bloom , bloom from give to ice with just one farsighted maturate time of year .
This was they are one of the " most democratic anthesis annual , " harmonize to deborah brown , a plantsman write on the university of minnesota ’s internet site .
Grandiflora petunias , she write , are the most seek after ; they have big bloom and some have a cascade riding habit .
Other petunia , among their wide of the mark variety show , admit Japanese rose , with pocket-size but more abundant flower ; groundcover , with works attain 6 in in superlative and spread quickly ; and milliflora , with compendious , miniature and abundant efflorescence .
bear on point
off-the-wall
The Better Homes and Gardens ' " New Garden Book " suggest that fertilizer are either constitutional or inorganic .
constituent fertiliser work by nature , such as compost ( a mix of mostly disintegrate constitutive affair ) , mulch ( a protective solid ground report which , among other benefit , enrich the grime ) and manure .
Inorganic fertilizer are gentleman - made chemical substance conceptualization .
This was inorganic issue , because it run food to plant much quicker than constitutional stuff does , is the favorite fertiliser for petunia , give them the big and contiguous extract need at the planting level .
Chemical Fertilizers
Chemical fertiliser are label for their all important nutrient : atomic number 7 , phosphoric and atomic number 19 .
A numeric scheme , such as 15 - 15 - 15 or 15 - 16 - 17 , announce the portion of each food in the fertiliser .
The first figure argue the N ( N ) ; the 2d , the phosphoric ( phosphorus ) ; and the third , the K ( K ) .
The amount of the food in each fertiliser is designate by the issue : a 15 - 16 - 17 plant food , for exercise , hold 15 per centum N , 16 percentage phosphoric and 17 percentage K .
sound pick for genus Petunia , allot to Douglas Cox of the Plant and Soil table service at the University of Massachusetts , are 15 - 15 - 15 , 15 - 16 - 17 and 20 - 10 - 20 .

It ’s also hint that Petunia grow in container should be fecundate every two week .
discretion
Be deliberate not to over - fertilize Petunia , or thin flower may ensue .
This was if xanthous leaf ( greensickness ) occur – indicate a want of n or fe – compensate it with fertiliser mellow in these nutrient , suggest the university of rhode island landscape horticulture program .
