Plants need nitrogen for protein synthesis, calcium for cell wall stiffening, phosphate for nucleic acid synthesis, and iron and magnesium for chlorophyll synthesis. The soil is often waterlogged , which favours the production of toxic ions such as ammonium , and its pH is an acidic 4 to 5.
No green thumb? No problem. We put together a guide to 10 plants that are hard to kill, including cast-iron plant, ZZ plant, and pothos.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
Plant damage is difficult to reverse, so corrective action should be taken immediately, supplemental applications of calcium nitrate at 200 ppm nitrogen, for example. Soil pH should be tested, and corrected if needed, because calcium deficiency is often associated with low pH.
The plant will then only drink as needed, self-regulating its hydration for low-maintenance, healthy, long-lasting plants. This trio in particular also doesn't need much light, which makes them ...

Other functions attributed to calcium are: the neutralization of organic acids; inhibition of some potassium-activated ions; and a role in nitrogen absorption. A notable feature of calcium-deficient plants is a defective root system. [14] Roots are usually affected before above-ground parts. [15] Blossom end rot is also a result of inadequate ...
Tip the plant on its side and gently ease it out of its old pot. Place it in the new pot, keeping the root ball as intact as possible. Fill in with soil, tamp down lightly, and water well.
