hibiscus needs a lot of potassium..ensure that you use fertiliser that has a high amount of potassium. it needs very little phosphorous and moderate amount of nitrogen. It's much better for hibiscus to be fertilized when their soil is a bit moist. If the soil is too dry, the nitrogen in the fertilizer can burn the roots and damage the plants.
Okay thanks a lot.. actually it's in pot so growing let..it also get kalis but thy get dry in few days after growing lil bit big.. :disappointed:
Put the veg waste in kitchen,like veg peel & the other things that we throw before cooking, this is very good for the plants. Used tea bag,or left tea leaves ,is also good.if it s in pot,u should change the mud every 6 months. Using the same soil,really affect the growth of plants.
