Plums, which are comprised of any of the various trees or shrubs in the genus Prunus (family Rosaceae) and their edible fruits. Plums are closely related to peaches and cherries and are widely eaten fresh, cooked into jams and/or baked into pastries. The European plum (P runus domestica) and the Japanese plum (Prunus salicina) are grown commercially for their fruits. The Japanese plum are for fresh consumption while the European is dried for prunes. A number of species, including the purple-leaf plum (Prunus cerasifera), are used as ornamental plants for their attractive flowers and leaves. Plum trees grow best in deep sandy loam soil with good drainage. California produces both the Japanese plum and European plum.
Fruit set is categorized as the critical transition period shortly after fertilization as plant processes switch over to fruit formation and growth. A successful fruit set is integral to a healthy crop at harvest. This process can be improved with the addition of Cytokin® at key timings. Cytokin® contains plant growth hormones responsible for cell division, cell enlargement, and various other plant growth functions. The nature-based plant growth regulator effects help to maximize conditions necessary for fruit set and early fruit development.
Cytokin® is a plant- based EPA registered plant growth regulator designed to increase crop production efficiency.
Flower production and bloom is an integral part to the development of a healthy crop. For a robust harvest to occur, significant flowering is necessary for fertilization. A number of key micronutrients are integral for flowering, and when they are not available or are deficient in the soil, this can lead to a diminished or reduced bloom. ZMC Express® provides a well-rounded mix of micronutrients to address numerous plant functions occurring during bloom. By delivering more than just one micronutrient, balanced interactions between nutrients within the plant are maintained.
ZMC Express® is a chelated EDTA blend of micronutrients.
Fruit Sizing and Development
Fruit development is an exceptionally important and nutritionally taxing period within a plant. Potassium is a critical nutrient at this time as it is responsible for translocation of proteins and sugars, water balance in plants, production of ATP, root development, improving quality of the fruits by maintaining desirable sugar to acid ratio, ripening of fruit and many other processes. Sugar Express® serves as an ideal nutritional choice at this critical time to provide critical nutritional needs at key timings. The addition of Calcium Chelate at this time can also assist in improving development and fruit firmness through the strengthening of cellular structure.
Sugar Express® 4-10-40 is a highly refined fertilizer with the appropriate ratio of phosphorus and potassium designed to be used close to harvest.
Environmental or abiotic stress has the potential to negatively impact plant health, productivity, crop quality, and ultimately yield. With the unique formulation of Greenstim®, these abiotic stressors can be mitigated via a multifaceted approach. With the addition of Greenstim®, water retention, overall plant metabolism, as well as general plant recovery can be improved. By managing abiotic stress effects, yield losses can be potentially minimized. Best effects are observed when applied prior to stressful conditions.
Greenstim® 2-8-14 is a proprietary liquid fertilizer combined with plant betaines.
Delayed Fruit Ripening
During periods of rapid growth, fruit development and ripening, plants require energy for proper physiological development and high levels of calcium for fruit quality. Physiological and environmental crop stress slows down plant metabolism and the movement of calcium within plant tissue. Consequently, plants suffer, and crop development is weakened, while fruit frequently lacks the necessary nutrients (including calcium) required for optimum harvest quality. Calexin® translocates through the phloem and xylem increasing calcium mobilization to fruit while supporting natural color development.
Calexin® is a translaminar calcium formulation which works to supplement with the plant's natural ripening and coloring stages.
