Appropriate nutrient management is crucial for producing high - quality plants throughout each growth phase . Understanding how fecundity requisite exchange over time allows growers to tailor-make their practices for optimum industrial plant wellness and performance . Fertility needs vary not only by the specific level of product but also by plant life coinage .
During commercial output , seedling may only need 25 to 50 part per million ( ppm ) of nitrogen fertilizer during Stage 2 ( porta of cotyledons ) and Stage 3 ( opening of first true leaves ) . While the plant life is get for sale , it falls into a light , intermediate or heavy prolificacy category . For example , begonias need relatively low birthrate compared to chrysanthemums . Once the plant is polish off and sell to customer , its garden carrying into action reckon on pH and fertility level provided .
During the 2024 Michigan Garden Plant Tour , Mast Young Plants ran a fertility test to show customers what unlike species will front like with either no fertility at all , one app of slow exit fertilizer , or constant liquid feed at 150 ppm nitrogen . In the 2024 test garden leaflet , the picture show the difference between different cultivar and the compass of fertility and their garden operation .
Growers wo n’t be surprised that the plants that looked tumid and beautiful were those receiving changeless liquid fertilizer at 150 ppm . For example , the petunia ' Bees Knees Yellow , ' which has been chosen as a top performing artist at different garden trials , perform poorly when give no fertility ( just clear water ) after transplant compare to the plant receiving the 150 ppm of liquid fertilizer .
Researchers at Michigan State Universtity would ask that any genus Petunia , garden mum or heavy - feeding plant would see like under the weather condition . These plants require a little extra maintenance from the nurseryman to look their best . However , some plant looked a hatful expert than others with very little to no fertility supply . Begonia Adora ' Velvet Red ' , Coleus Main Street ' Ruby Red ' and Coleus Talavera ' Sienna ' all performed comparatively well considering the low or no fertility throughout the time of year .
As consumers are betray this spring , believe your watering and fertility rate habits if you ask time of year - long big , gorgeous plants . If you want to grow the gorgeous , full genus Petunia determine at the garden center , you will need to continue the rankness regimen and even cut them back a couple of times throughout the summer . Many garden core ' social medium accounts will prompt you ( around the Fourth of July ) to tidy up the plant habit heading into the second one-half of the growing time of year .
If you ’re someone that does not regularly fertilize plants , view lower - sustainment plants such as begonia and coleus .
