Plumbagos aretropical blooming plantsprized for their true - blue blooms , although some cultivars bloom white-hot . They tolerate mild drought and bloom most of the yr in areas affectionate enough for them to live — namely the southernmost region of the Southern Department of State as well as coastal region . They need very little help from plant food to boom .

To Fertilize or Not to Fertilize

Plumbagos are a low - maintenance garden and landscape painting industrial plant . They survive , grow and bloom in even the most nerve-wracking soils , though they ’ll surely perform well if the stain is healthier . But if the plant is producing gullible leaves and bloom , it does n’t ask plant food . fertilise when it is already goodish only encourage the works to put on an abundance of weak increment that is more susceptible to attack from louse and damage from uttermost conditions .

Organic Fertilizer and Compost

Planting plumbagos in compost - rich land precludes the want for most fertilizers . But organic fertiliser give plumbago a gentle hike when they ’re growing very slowly or when their leaves are yellowing from deficiency of nutrition . The organic fertilizer should have a balance of macronutrients — nitrogen , phosphorus and atomic number 19 — and have rich micronutrient as well to assure that trace nutrient requirement are also met . Coarse compost as a mulch will also strip nutrients into the grime at a rate the plumbago can use comfortably .

Chemical Fertilizer

If you do require to kick upstairs bloom of youth , apply a 10 - 30 - 10 fertilizer . The three numbers racket represent atomic number 7 , phosphorus and potassium , respectively . The Lucifer is the highest of the three , and this is the macronutrient that help boost flower . Chemical fertilizers should not be apply or spilled onto any foliage because they tend to burn it . They should be watered gently into the soil after software to avoid overspill , which neutralize the plant food and causes pollution .

Considerations

A soil test will reveal if the soil has any nutritional deficiencies . The most common deficiencies that induce detectable problem in plumbagos are atomic number 26 and N deficiencies , since these turn the folio yellow . Alkaline soil will keep plumbago from absorbing nutrient , even if they are present in the soil . In these case , a soil acidifier should be used instead of a fertilizer .
