How to water
Regarding the correct irrigation of gaura, it is recommended to proceed with a certain regularity during the months from March to October. In any case, gaura is able to tolerate periods of short drought, therefore, even altering the frequency of wetting, gaura should not be affected. Whenever you intend to proceed with an irrigation, it is good to carefully check the soil. Should it still be wet from the previous wetting, it is not necessary to irrigate to avoid the formation of water stagnation. These stagnations are the primary cause of the submersion and asphyxiation of the roots and generate the consequent root rot, one of the main causes of death of the plant. Regarding the water to be used, the gaura does not present any particular needs.
How to cure
Gaura is a rustic plant and is therefore able to withstand the harshest climates without suffering any damage. It is possible, therefore, to leave the plant outdoors even in winter as the vegetation will lose its leaves and flowers in order to protect itself from the elements. The plant is multiplied by seed during the month of February and in a special seedbed, or by planting it directly in March or September. If you have a specimen of gaura, it is good to proceed with its multiplication as the plant is not easily found in all nurseries. The gaura must be planted in a predominantly sunny area. The soil to be supplied to the plant during the planting process must be fresh and thoroughly worked to allow the roots to stick to the best.
How to fertilize
The fertilization of gaura must take place during the hottest months. It is recommended to proceed with the use of specific fertilizers for flowering plants that contain equal doses of the three fundamental chemical substances: nitrogen, phosphorus and potassium. The fertilizer can be administered in liquid form by diluting it with irrigation water in slightly lower doses than reported on the package. Fertilizations must be suspended completely, or drastically reduced, during the winter months. Continuing with the fertilizing process, in fact, would stimulate the plant to produce new shoots that would not be able to survive frost. Gaura can adapt to arid soils or even to loose and well-drained soils and can therefore be grown in normal garden soil.
Gaura: Diseases and remedies
As a rustic plant, gaura is not easily attacked by insects and parasites. Rarely, the plant can be infested with aphids, or plant lice. In the event that the presence of these parasites is noted, it is advisable to proceed with the use of special pesticides. Gaura rather fears root rot, a pathology that leads to the death of the plant and that is generated by excessive irrigation in the presence of still damp soil. It is good to carefully check the substrate before irrigating and also check that there is no excess water in the saucer. As for the cold or atmospheric agents, gaura seems to be a very resistant plant. It is able to adapt to winter losing the leaves and flowers that will sprout again with the arrival of spring. It is good to place the gaiety in sunny places in order to obtain a copious bloom.
