Fertilization Picea engelmannii var. engelmannii
Trees tend to find a great part of nutrients in the soil, because their roots spread more than ten metres; in any case it is advisable to feed the soil with amendants, to guarantee a good quantity of mineral salts; every 2-3 years, in the spring or autumn, we suggest adding to the soil at the feet of the trunk, about a bucket of mature organic fertilizer.
Watering Picea engelmannii var. engelmannii
We suggest watering pretty often and regularly, with 2-3 buckets of water ; we should always wait for the soil to be clearly dry between one watering and the other. During this time of year usually it is necessary to irrigate every 2-3 weeks . The young specimens, recently sheltered, need more cures compared to the adult specimens: as the years go by the development of a good radical apparatus allows the plant to be satisfied with the rain, without needing other waterings.
Treatments Picea engelmannii var. engelmannii
The spring weather, with a high temperature swing between the day and night hours, and pretty frequent rains, can favour the development of fungus diseases, which should be treated pre-emptively with a systemic fungicide, to use before the gems grow excessively; at the end of the winter we also suggest a wide range insecticide to prevent the attack of aphids and cochineals. We should always remember to do these treatments when there aren't flowerings in the garden.
