The most important factor when it comes to plant growth is soil fertility. There are parasite plants like Orchids and Mints that need no soil to grow, but I wish to discuss facts in favor of plants that do need soil (over 90% of the plant population).
Say, you are a domestic gardener-to-be. Can you just walk outside and figure out whether the soil below your feet, is fertile enough? Well, of course. You can determine the soil fertility, by the color, moisture, feel and the smell of the soil. Sounds strange, isn’t it? If it does, then you know you are new to the whole gardening business. A person with a bit of experience will know exactly what I’ve said.
If the soil isn’t fertile enough – probably due to extreme weather conditions, over exploitation or erosion – right quantities of the right kind of fertilizer will be your only way out. Things like crystallized minerals, compost (natural fertilizer) or liquid fertilizer must be added periodically.
Nevertheless, the difficult part is when you have to maintain the plants, without letting them wither. This may demand a bit of your attention unless the soil is fertile up to the required levels. If, not you may try planting Cacti, they do have pretty flowers, Butterfly Weeds or Blackfoot Daisy in your garden.
Just remember, when it comes to soil fertility, ‘the more you add, the more you can grow’
