It is well known that temperate fruit crops (including fruit trees, grapevines, and berry crops) use reserves to support the initial vegetative growth and fruit set in the spring until the new growth shifts from being a sink to a source of carbohydrates (this happen about 3-4 weeks after bud break). This period between initial spring growth and the beginning of fruit development is critical to secure high yields of quality fruit, and it relies almost exclusively on the reserves from the previous year.
Then the question is what can we do to increase reserves to have a successful beginning of the season next year? Fall nutrient application seems like an opportunity to boost reserves, however many research studies have had mixed results when fall nutrients were applied, probably because effectiveness of these applications will depend on many other factors such as tree health and nutritional status, soil nutrient levels, cropping levels, etc. Here are some general recommendations for fall nutrient application.
