An ornamental garden requires more care than a vegetable garden. Does this mean you should neglect your vegetable garden? Of course not! Any vegetable garden will be less forgiving if you opt to neglect it.
If you neglect your garden, your veggies will spend more energy spreading, producing as many vegetables as possible, and may even flower after maturity. The frustrated vegetable plants will produce lower yields and inferior vegetables. Pest and disease will set in and kill your garden altogether.
