We suggest to position the the Prostanthera rotundifolia in a sunny spot at least a few hours a day. To prevent damage caused by the cold temperatures, during the months with definately harsh minimum temperatures, we can protect the shrubs by covering the soil around the stem with straw or dry leaves.These plants don't like excessively harsh temperatures, with night-time minimum temperatures below 0°C. during the spring in general they are grown in a covered place, moving them outdoors, or uncovering them, when there isn't any danger of sudden temperature drops.
Cultivation Prostanthera rotundifolia
These plants have a sapling deportment, with a short stem with a small roundish crown. The Prostanthera rotundifolia Is medium in size; in summer it assumes a purple colouring. These are evergreen plants, which means they keep their leaves year round. The Prostanthera rotundifolia has a shrub- like development.
Fertilize Prostanthera rotundifolia
Shrubs develop new shoots and prepare their flowers during the spring period, therefore we must remember, by the end of the winter, to give it a good dose of humus or mature manure, or granular slow release fertilizer, to be added to the soil at the foot of the plant. During the spring we can choose a fertilizer rich in nitrogen and potassium, to mix with the irrigating water, every 20-25 days.
Water Prostanthera rotundifolia
Water sporadically, with 1-2 buckets of water , leaving the soil dry for a few days before watering again; when watering we suggest avoiding excesses, but to wet the substratum well. Let's act every 2-3 weeks . If we want to grow these plants in a vase, we should water them a bit more often, compared to plants cultivated in the ground; Every 2-3 years we should renew the substratum in the vase, or enrich with organic amender.
Pests Prostanthera rotundifolia
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.
