When topdressing is needed in the growth and development period of perennial flower plants(rooting tray), the soil surface should be loose and clean without weeds, and the soil moisture content should be low. All the substances applied in the soil or sprayed on the aboveground parts of flowers, which can directly or indirectly supply nutrients to improve the quality and yield of flowers(ten gallon pot), are collectively referred to as fertilizers.

If it can't be touched and the bud is dry, it means that the grafting has failed and can be supplemented(v15 nursery pots). After reasonable artificial composting, the nutrients are complete, including not only nitrogen, phosphorus, potassium, but also trace elements, hormones and antibiotics(black succulent pot). It can improve the physical and chemical properties of soil, slow and lasting release of fertilizer effect, but the effective content is slightly lower.(long life propagation trays wholesale direct canada)
Suitable for Topdressing of perennial flowers in open field are(nursery tray): dry manure, thin manure, bean cake, sesame paste residue and other fertilizers; when topdressing, it can be applied in furrow or hole, which should be a little far away from the plant; if human manure is used as topdressing, it should be flushed with water(black plastic growers pots). However, if the air humidity is too high, herbaceous plants, especially seedlings, are susceptible to diseases.
(long life propagation trays wholesale direct canada)In the garden exhibition area, the top dressing mainly uses chemical fertilizers(germination tray price): such as 0.5% ~ 1% ammonium sulfate, 0.1% ~ 0.3% potassium nitrate, 0.05% ~ 0.1% superphosphate, 0.2% ~ 0.5% calcium nitrate, and 0.1% ~ 0.5% potassium dihydrogen phosphate as external topdressing(bulk fabric pots). There are a wide range of materials that can be used as base fertilizer. It is very important to improve water quality for perennial flowers in acid soil.
If the pH of irrigation water is greater than 7(72 cell plant tray), a certain proportion of organic acids, such as citric acid, acetic acid, or acidic chemicals such as ferrous sulfate, should be added to reduce the pH value of water quality. Soil drought: due to dry air, long-term evaporation of soil, and no water supplement (irrigation or precipitation), the soil will be dry, unable to supply water needed by flowers(black plant pots plastic), leading to plant wilting and death.(long life propagation trays wholesale direct canada)
The commonly used trace elements are: iron fertilizer ferrous sulfate(heavy duty plug trays), which is usually used as base fertilizer or 0.2% - 1.0% foliar spray after composting with organic fertilizer in the proportion of 1% ~ 5%; boron fertilizer boric acid, commonly used at 0.025% ~ 0.1% concentration(heavy duty plastic planters), is conducive to improve the fruit setting rate of ornamental flowers (0.3% topdressing). The suitable pH value of flower irrigation water is 6.0-7.0, which is slightly acidic to neutral.
If there is salt in irrigation water to make water conduct electricity(72 cell flats), the inverse of resistance (Ω) of lcmxlcm × LCM aqueous solution is used as conductivity, and Siemens per meter (s / M) is usually used as the unit; the conductivity of irrigation water should be low (< 0.5s / M). At this time, the liquid topdressing can be easily absorbed by the plant roots and the fertilizer efficiency is high. In the same year, part of the branches and leaves should be cut.
(long life propagation trays wholesale direct canada)After the leaf bud of cutting stock grows, the binding material should be removed in time(50 cell tray). The cutting stock is generally reserved for the next spring. The cutting stock should be 2 cm above the joint, and the section should be inclined to the opposite side of the bud. There are many kinds of branch grafting, including cutting, splitting, abdominal, butting, tongue and flat connection(plastic plant pots outdoor), and the most important is cutting and butting.
