How to Care For Your Plants
Most Gardeners are introduced to double and triple gerberas when they purchase a few
at a gerbera show or at a function like garden week.
Soil or Potting Mix pH
It is important to have the pH within the required limits if optimum growth is to be obtained.
Unless the pH is between 6 and 7 it is unlikely that the plant will be able to absorb the nutriments
it needs even if there are ample fertilisers in the soil.
Gerberas do not require a richly fertilised soil. Too much nutrient matter often leads to excessive leaf growth and less flowers. If plants have too many leaves for the size of the crowns (say 30 for a mature 6 month plant) all lower and any cross growing leaves should be removed. Do this by sliding a finger down to the base of the leaf, bend back and twist. If the leaf does not come away with minimal effort then cut it off as close to the crown as possible It is recommended that no stems stub should remain. Removal of old discoloured or damaged leaves should be by the same method.More information on pH from Department of Agriculture and food
Where to Position Your Plant
Gerberas love full sun except at the height of summer. During WA’s 40 degree heat, plants can benefit from some filters shade, but if this cannot be provided it does help to give the gerberas a fine spray of water twice a day during the hottest part of the day.
