If a lawn is fertilized and it doesn't rain, the grass often dies. why?

he reason for this is the fertilizer must be dissolved in water so the plant's roots can ingest it. It cannot be used if it stays dry and because it is a mild salt it can kill the grass if it stays in contact too long. Cause the ground needs to have moisture to keep the roots from drying up. When the roots dry up the plant dies. Thus dead grass. Water more often and you can build up a hardy grass that can go longer without the need for lots of watering. Without the rain to dilute the fertilizer, it burns the grass because it's too strong. Most fertilizer is water soluable and without the water, it's too "hot".

Pick off any flowering parts - that's easy. The bugs or diseases are harder - you need to diagnose it and find a solution. Does it have little spider webs? It might have spider mites. They are hard to control but you can try spraying it with a soapy solution (see link). Well, first things first. If it's wilting, you've stressed the plant. When stressed the cannabis plant can turn hermaphrodite and fertilize itself and leave you with some nasty seedy bud. Next time you try, study before you plant so you can grow a stress free plant the will produce good seedless buds.
