At this point, it might be easiest to just accept that you're not going to have a bush there. Tomato plants are very sensitive to certain pollutants found in the exhaust from fossil fuels. The major pollutants that result from burning kerosene are nitrogen dioxide, carbon monoxide, carbon dioxide, sulfur dioxide and formaldehyde. One of the problems is that carbon dioxide is most effective when light levels are the highest during the day and the carbon dioxide is mainly produced at night when the heater operates the most. The flame should burn clear blue. Our shrubs in the surrounding area are slowly dying off. Once the sulfur dioxide enters the plant through the stomates, it reacts with water to produce sulfuric acid that will cause leaf burn, flecking and general chlorosis. Ethylene damage seems to be most common on new heaters not installed properly, and on heaters more than six to eight years old. WebGrasses and perennials that grow more than 6 inches high should also be planted at least 2 to 3 feet away from the base of the unit because ventilation for the unit is also drawn from that area.
