Fertilizer "20-27-5"?


First # is nitrogen - overall plant growth
second is phosphorous - flower development
3rd is potassium for root growth.
Established plants hold a developed root system so this fertilizer will work fine to make the plant grow and bloom.
Fertilizers are generally sold near the main elements shown as a ratio, ie. the N:P:K mix. Here, you hold high level of Nitrogen - the N, higher level of Phosphorous - the P, and fairly low level of Potassium - the K.

Nitrogen is largely responsible for the green growth that plants make.
Phosphrous is largely responsible for root growth.
Potassiium is largely responsible for flower initiation.

As such, this fertilizer mix would be beneficial for encouraging standard growth, rather than flowering. It could be impressive when establishing new plants, or wanting them to crowd out, rather than flower really in great amounts.

Plants typically need other nutrients than these primary 3 types, some plants more than others, Citrus and Palms benefit here, amongst others. Usually fertilizers will contain other trace elements too, though it does depend on their purpose.

If you're looking for good broad growth, encouraging root and above ground growth, with smaller quantity interest in flowers next this formulation could work well. Some plants will merely be able to utilize bitter type fertilizers, these are ericaceous plants, including Rhododendron, Azaleas, Camellias, and you can get ericaceous fertilizers for these.

Hope this help. Good luck! Rob

Are you playing around? what do you mean
"20-27-5" ?
Early contained by the morning, just lurk near the
suburban guardrail tracks; specially where
near is a "crossing and no Manning".
You will find plenty of fertiliser.
Answers:    N.P.K. this shows the % of each surrounded by the fertilizer, each does a difeerent duty for the plants, foliage (green.), fruits and flowers , roots.
