Once they become better established, you can water less frequently to avoid over-watering.  Keep the plants well watered without making the soil soggy.  If your garden area may experience drought, consider installing an irrigation system.  This will prevent the soil from becoming excessively dry, which can then hinder tobacco growth.  If you expect a few days of light drizzles or rain, you can water even less frequently.  The structure of the tobacco plant's leaves enables the plant to collect and funnel the water down to the base of the plant. Fertilizers used for tomatoes, peppers, and potatoes are also suitable.  Over-fertilizing is a serious concern, as it can cause damaging salt accumulation.  The application amount will depend largely on the grade of the fertilizer, the natural fertility of the soil, losses of nutrients due to leaching, and other subjective factors.  Consult your fertilizer's directions for the most optimal usage. It is recommended that you apply the fertilizer several times.  Once the tobacco begins to flower, there should be no need to fertilize further. Topping is the removal of the terminal (center) bud and allows the upper leaves to get larger and thicker than if they were untopped.  The terminal bud is the most prominent and is typically located at the very top of the stem.  The top can be removed by simply breaking or cutting it off, preferably before any flowers open. Soon after the top is removed, axillary buds or suckers will develop at each leaf.  Remove these by hand as well, otherwise they will reduce the tobacco's yield and quality. You can also pull up soil around the base of the plant to help strengthen it.  Tobacco roots grow quickly and the root structure is quite large, with thousands of small hair-like feeder roots that grow close to the soil surface.  Be careful when tilling or hoeing, as penetrating the soil too deep can damage the roots. After 3-4 weeks from planting, heavy tilling should be stopped and only light scrapings to control weeds should be done. Common...
