Fuchsias sometimes benefit from a    monthly watering with some Epsom salts in the water.

Another boost to the plant or to hurry up flowering is to soak chopped up banana skins in water to be watered on to the plants.

   Lawn clippings left to soak in a bucket  of water will provide extra nourishment-  Be careful not to let any clippings  get on to the   plant or even on the soil around the  plant  or they may attract fungal diseases.  Just add some of the strained  water to the watering can. --Usually I use it as a soak  stand my plants in rather than watering on
