The general rule of thumb - apply a well balanced (14+ nutrients) fertilizer weekly, WEAKLY - is a good starting point. Preparation of our Orchid Feeding Solution (1 Package (1 tsp) to Make 1 Gallon) produces a good weak fertilizing solution for almost all orchids. Orchids will absorb very small amounts of the mineral nutrients they need. Overfertilization and Overwatering can cause serious health problems in your orchids. If you live in a hard water area, it is likely that your tap water will contain sufficient quantities of at least some of these micronutrients, like chlorine and iodine. As with our Orchid Feeding Solution, we recommend you use tap water to get sufficient quantities of at least some of these micronutrients.
Our 15-22-13 + Micronutrients fertilizer contains the following additives and benefits:
NO UREA NITROGEN. No fertilizer burn of roots using too much urea, only a combination of Ammonical and
HIGH CALCIUM AND MAGNESIUM. Calcium produces firmer stems and leaves. Calcium is vital for cell wall
formation and strength; as well as improving disease resistance. Magnesium aids in better leaf
formation and photosynthesis. The availability of magnesium to orchids is subject to the soil pH.
SULFUR. Combined soluble forms of sulfur aid in living orchid cells and various amino acid prodcution.
BORON. Plays an important role in buds and flowering. Deficiency will exhibit leaf deformation with patches of
COPPER. Is essential of proper photosynthesis. Stunted growth, twisted leaf tips, and yellow leaves are the
symptoms of copper deficiency.
IRON. Is essential for energy transfer and nitrogen reduction. Lack of iron produced yellow leaves. Deficiency
exhibits chlorosis between the veins of new orchid leaves.
MANGANESE. Is essentil for proper photosynthesis and nitrogen metabolism. Prevents new leaf drop and
delayed leaf maturity. Deficiency also exhibits chlorosis between the veins of new orchid leaves.
MOLYBDENUM. Is responsible for pollen formation in orchid flowers and deficiency produces chlorosis of
orchid old leaves.
ZINC. Helps in photosynthesis, orchid plant energy, and leaf production in the size or new leaves.
CHLORINE. Helps in osmosis and ionic balance. Decreased orchid plant resistance and reduced plant growth
are symptoms of chlorine deficiency. However, the use of chlorinated tap water when mixing Orchid
Feeding Solution and the addition of sea kelp extracts, provide enough chlorine for orchids.
COBALT. Is essential for stem growth, elongation of orchid leaf coleoptiles, and helping the orchid reach
maturity. However, an overdose of cobalt may result in the toxicity of orchid plants. The very small amounts
from orchid potting media and sea kelp extracts will provide sufficient quantities.
