Tips for working with humic acids and plant hormones in orchids
Epiphytic orchids mostly live or in poor soil. Humus components from decomposed organic matter are therefore good for their care.
Spraying or dipping Recommendation: Humisol continuous 50 ml to 5 liters of water every 4 weeks or in the professional range 100 ml to 5 liters every 3 months.
Spraying or dipping recommendation for large stocks of 20 orchids Agro Stimuline ® 1 ml to 10 liters of water Humisol 100 ml every 80-90 days Agro Stimuline ® is packaged as the smallest unit with 1 ml after opening and consume within a day. Orchids can be particularly at seedling stage also tolerate higher doses of these mixtures. The best experiences were made with Dendrobium,Phaleonopsis, Cattlaya and lady's slipper. The administration of Humisol can also at 200 ml per 10 l spray mixture are brought. Alternative to Humisol offers at Biolife U. Here, 500 ml per 10 l spray mixture is required. It contains a higher number of biologically-active ingredients as Humisol. The experience in other cultures has shown that an inter-temporal transfer of humic acids in small quantities, analogous to the above spray version in half the time or a continuous administration is beneficial in reducing by half doses.
Neubewurzelung of problem plants: From the practice was to note that the special agricultural product Stimuline ® W is ideal for problem plants, such as women's shoes were rotted at the roots to take root again. However, the plant needs to be treated not immediately placed in the substrate. Agro was used Stimuline ® W 1 ml to 1 liter of water. After removal of decaying and dead roots of plants were then sprayed in the root zone drip and remained about 4 weeks in a box in a warm humid environment (greenhouse or foil bag). We recommend for better absorption of solution 2 g Lignohumat ™ AM annexed. Lignohumat ™ AM is also included in orchids proliferation in agar cultures and there was a significantly better rooting of multiplication cultures.
Fertilization: You should fertilize orchids very sparingly. The treatments help to Humisol that usually can be removed enough from the substrate without decomposing it. If you want to fertilize should still use low-nitrogen fertilizer. We recommend e.g. Biplantol ® verde.
