Control of non-infectious physiological Diseases of Flowers in Summer and Autumn

Non-infectious physiological diseases: the most prominent are sunburn and drought and waterlogging. In addition to succulent positive flowers such as cacti, which can withstand strong light in the open air, neutral, negative and strongly negative flowers should be given 40% shade and 80% shade, and shade canopies should also be set up to prevent sunburn.

If the topsoil is slightly dry, you should slowly pour enough water, spray water sooner or later, and sprinkle water around the plant at noon to cool and moisturize. In case of heavy rain and continuous rain, it is necessary to dredge the basin hole in time to prevent water stains on the roots, resulting in anoxia and wilting of the roots.

In addition, it is important to apply 2% potassium sulphate (nitrate) liquid fertilizer every seven days, twice in total, to improve the stress resistance of the plant.
