Water Deeply Just Before Winter
Watering flowers at the right time and in the right quantity is a great help in your efforts to protect your flowers in cold weather conditions. November is generally the month when the winter season starts knocking on the local climate, and this is the month you can water your plant deeply for the last time until end of the winter season. One thing you should be sure of is that your flowers will use the water during the entire winter season. So, the quantity should be enough. A common yardstick to measure the quantity of water is that it should stand in your flowers pot or ground for a couple of minutes after water them. You will be able to assess quantity yourself better if you are involved in gardening on a regular basis.
Add Natural Fertilizer Stuff
Fertilizers made out of banana leaves and other such things are better sustainable. So you can add things like banana leaves, tea bags and egg shells etc as fertilizers to your plants.
Spraying Fungicide and Insecticide
Some of insects try to get shelter in leaves of your plant in the winter season, leading to some diseases and damage of the plants. You should spray your plants with fungicide to protect them from diseases and insecticides.
Cover Ground Around Plants
You might be aware that roots of plants are spread around at a distance from trunk area. So it is better to cover ground around them at a measurable distance i.e. a feet, more or less. You can assess the size of the plant to determine how far their roots might have gone. Cover that area with leaves or straws accordingly. It will protect their roots in winters and they will have stronger power to fight off harsh winter weather.
Prune Your Plants
In your final inspection of your plant, just before the winter season, prune dead leaves off the branches. May be you spot some sign of disease of insects on the leaves, and if so better cut them out as well. It is another way to protect your flowers from sudden emergence of diseases in winters.
