What are the optimal soil compositions and microclimate conditions for maximizing both the bloom quality and disease resistance of Narcissus cultivars? Recent cultivation trials have indicated that slight variations in soil pH and drainage characteristics can significantly affect the health and flowering performance of these bulbs. Additionally, which integrated pest management strategies would you recommend for mitigating common fungal and pest-induced complications in both controlled garden settings and larger-scale nursery productions? Insights supported by recent empirical studies would be especially valuable.
