As the hot summer conditions continue, make sure you keep watering your bonsai plants. On the hot days, water two to three times a day, making sure the water runs out of the bottom drain holes.
It is time to repot and work with the tropical species.
Ficus can be repotted and defoliated. After defoliating figs, make sure you give them a lot of sun when buds start to emerge. Maybe even full sun. This will ensure the new leaves become much smaller. If you keep your defoliated fig in a shady spot the leaves will regrow to the same size or even bigger, thus defeating the purpose of defoliating.
It is time to repot your Bougainvillea and give them a light trim. Cut off all the old flowers (brats) to energise new growth and flowering.
Turn your bonsai pot 180 degrees to encourage equal sun penetration and healthy foliage grown all around your plant.
It is a good idea at this time of the year to water your plants, over foliage and soil, every week or two with a solution of kelp or seaweed solution.
As the very hot weather continues keep the towel cover over the pot.
