What are the fertilizer precautions for flowers in July
July is a key period for flower growth and also a period when flowers have high fertilizer needs, so be sure to fertilize flowers well in July to promote their growth.
Precautions for fertilizing flowers in July:
In July, there are four major categories of ornamental plants that should have their fertilizer management strengthened. First, types with a particularly long flowering period, blooming from spring and summer into autumn, such as white magnolia (Magnolia denudata), Chinese rose (Rosa chinensis), Milan (Aglaia odorata), jasmine (Jasminum sambac), etc.; second, types that bloom abundantly in autumn, such as chrysanthemum (Chrysanthemum morifolium), osmanthus (Osmanthus fragrans), cotton rose (Hibiscus mutabilis), etc.; third, types grown in winter for their flowers and ornamental fruit, such as bitter orange (Citrus aurantium var. amara), nandina (Nandina domestica), wintersweet (Chimonanthus praecox), azalea (Rhododendron), etc.; fourth, foliage plants, such as broadleaf lady palm (Rhapis excelsa), Swiss cheese plant (Monstera deliciosa), goosefoot plant (Syngonium podophyllum), rubber tree (Ficus elastica), etc. As for the types of fertilizer: for the first three categories, in addition to the necessary nitrogen fertilizer as a top dressing, an appropriate amount of phosphorus and potassium fertilizer should also be applied to meet the plants' full needs for nitrogen, phosphorus, and potassium, and to provide sufficient nutritional guarantee for their bud formation, flowering, and fruiting; for foliage plants, thin cake fertilizer liquid or urea solution should be the main choice. As for the application method, watering with thin liquid fertilizer is preferable.
In July, the herbaceous flower types that should have their fertilizing strengthened include: scarlet sage (Salvia splendens) (white, purple, pink), cockscomb (Celosia cristata), China aster (Callistephus chinensis), zinnia (Zinnia elegans), globe amaranth (Gomphrena globosa), chrysanthemum (Chrysanthemum morifolium), black-eyed Susan (Rudbeckia hirta), dwarf petunia (Petunia hybrida), golden shrimp plant (Pachystachys lutea), shrimp plant (Justicia brandegeeana), Cymbidium ensifolium, marigold (Tagetes erecta), four o'clock flower (Mirabilis jalapa), and dragon's mouth flower (Antirrhinum majus), etc. Woody flowers include: crape myrtle (Lagerstroemia indica), pomegranate (Punica granatum), poinsettia (Euphorbia pulcherrima), banana shrub (Michelia figo), osmanthus (Osmanthus fragrans), camellia (Camellia japonica), sasanqua camellia (Camellia sasanqua), Chinese hibiscus (Hibiscus rosa-sinensis), jasmine (Jasminum sambac), white michelia (Michelia alba), Milan (Aglaia odorata), night-blooming jasmine (Cestrum nocturnum), Chinese rose (Rosa chinensis), crabapple types (Malus spp.), Brunfelsia (Brunfelsia pauciflora), bougainvillea (Bougainvillea spectabilis), azalea (Rhododendron), Chloranthus spicatus, wintersweet (Chimonanthus praecox), rose of Sharon (Hibiscus syriacus), cotton rose (Hibiscus mutabilis), etc. There are relatively many kinds of foliage plants, such as bromeliads, Brazilian ironwood (Caesalpinia ferrea), broadleaf lady palm (Rhapis excelsa), Norfolk Island pine (Araucaria heterophylla), arrowhead plant (Syngonium podophyllum), maranta (Maranta arundinacea), giant taro (Alocasia macrorrhizos), red ruby (Fittonia verschaffeltii), sago palm (Cycas revoluta), rubber tree (Ficus elastica), Swiss cheese plant (Monstera deliciosa), and ti plant (Cordyline fruticosa), etc.
