If you try to overstimulate growth, you end up with weak plants. Insects and disease will cause more problems for your plants, and they may more easily succumb to drought or a wet spring. If you go the opposite route and try to plant everything too close together, it will look horrible in five or ten years. Then you'll be forced to re-do your landscape. Better to plan for your plant's growth, than to try and move large shrubs and trees.
Organic gardening can be a wondrous experience.
