Diseases are not common on most houseplants grown indoors because environmental conditions are not favorable for plant pathogens to grow and infect the plants. Control of diseases begins with prevention. Always buy disease-free plants. Use pasteurized soil when repotting.
Jupiterâs atmosphere is the largest in the Solar System. Molecular Hydrogen and Helium make up most of its atmosphere as well as small amounts of ammonia, methane, hydrogen sulfide and water.Gases such as nitrogen sulfur, noble gas and oxygen can also be found in the planet.The gaseous part of the atmosphere slowly transitions into the liquid part of the planet.olecular Hydrogen and Helium make up most of its atmosphere as well as small amounts of ammonia, methane, hydrogen sulfide and water. Gases such as nitrogen sulfur, noble gas and oxygen can also be found in the planet. The gaseous part of the atmosphere slowly transitions into the liquid part of the planet.
In the top one-fourth of the planet, the pressure and temperature are so high that the hydrogen atoms are stripped of their outer electrons, forming a liquid metal. Like Jupiter, Saturn has a thick atmosphere composed of hydrogen and helium. The ratio of hydrogen to helium ratio decreases with depth. Methane and ammonia are also present. The atmosphere of Saturn envelops a thick layer of metallic hydrogen. The atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere are composed of crystals of methane. -=-=-=-=- Since gas giants do not actually have a surface, it is rather difficult to determine where their atmospheres end.
