(Mn) - Manganese plays an essential role in chlo- rophyll production, nitrogen assimilation, and the formation of proteins. Manganese stimulates seed ger- mination and has been linked to the speed at which a plant matures. (Cl) - Chlorine is involved in the stimulation of photosynthesis. (B) - Boron is essential for tissue growth within the plant. Boron helps promote the absorption of water and regulate a plant’s metabolism. (Zn) - Zinc helps with the development of en- zymes and growth hormones. (Cu) - Copper helps activate various enzymes and plays a role in chlorophyll production. (Mo) - Molybdenum is needed for the produc- tion of nitrogen-based proteins. (Ni) - Nickel regulates mineral metabolism, enzyme activity, and other metabolic processes in plants. Nutrition for Seedlings and Clones In addition to consistent atmospheric conditions (arguably the most influential factor over cloning/ seedling success), gardeners can employ various nu- trients and nutrient additives to help clones/seedlings transition gently into the vegetative stage. During the first few days, neither seedlings nor clones require very much nutrition.

The first wave of nutrition for seedlings is actually provided by the seed itself. In most cases, a seed contains vital minerals and vita- mins for the initial emergence of the seedling. After the first few days, depending on the par- ticular plant variety, a horticulturist can begin a very light fertilizer regimen. For seedlings, a diluted “vegetative” base fertilizer (1/4-1/2 strength of the recommended dosage) will contain all of the essen- tial mineral elements needed for proper plant de- velopment. For soil gardeners, very little additional nutrients are required during the first few weeks of growth because the soil itself (depending on the composition) will likely contain all of the essential el- ements needed for healthy plant growth. As the seed- ling develops into a vegetative plant, the grower can increase the strength of the base fertilizer until he or she reaches the manufacturer’s recommended dose. Clones tend to be a little more finicky than seed- lings in terms of nutrition. Until the clone has de- veloped a healthy root mass, the provided nutrients should be geared toward root production instead of rapid vegetative growth. For this reason, many horti- culturists rely on clone specific fertilizer regimens or will use a diluted blooming base fertilizer (1/4 or 1/2 strength). A diluted blooming base fertilizer will still contain all of the essential mineral elements needed, but will also have a lower ratio of nitrogen to phos- phorus and potassium. This type of ratio is more con- ducive to root development than a “grow” fertilizer that is rich in nitrogen. Once the clone has developed a healthy root zone, its nutrition can be transitioned to a vegetative base fertilizer which can be gradually increased to full strength as the clone grows. Nutrition for Vegetative Plants A good base vegetative fertilizer containing all of the essential mineral elements is a great start for vegetative plants. During the vegetative stage, plants should have a balanced diet with a higher ratio of nitrogen. Nitrogen is used by plants for the develop- ment of healthy, green leaves and branches. In addi- tion to a vegetative base fertilizer with a high ratio of nitrogen, growers can supplement various additives which aid in vigorous growth and increased struc- tural integrity. Some of those additives include plant hormones, amino acids, vitamins, trace elements, silica, beneficial microorganisms, and enzymes. Dur- ing the early vegetative stage or the transition from the clone/seedling stage, it may be a good idea to dilute the fertilizer (1/2-3/4 strength) until the plants have become acclimated to their new home. Growers rarely realize how drastically the environmental con- ditions change when moving a plant from one stage to the next. Lessening the potency of the fertilizer, even for a few days, can make a huge difference in www.GardenandGreenhouse.net March 2019
