I’ve been growing tomatoes for years and am always looking for ways to improve. There are a couple of schools of thought on how to make the vines more productive. One school advocates for cutting off suckers, the energy consuming growth that does not produce fruit. And what I’ve noticed over the years is that if I don’t, the plant does it itself. When the fruit starts growing and ripening, the plant needs to direct the energy there and the suckers die off on their own. It naturally eliminates non-productive parts.
Nature has a way of demonstrating what should happen. In business, we should look every year for non-productive activities, business lines, services, etc. and eliminate them. Things that don’t produce or support growth should not continue to consume energy or investment that is better used elsewhere.
