2013417 Actively growing plants are the best choice whereas hardened plants may take a while to start growing again. Ideally, choose a large plant (four inch pot) that is actively growing, but generally it’s better to choose a small, actively growing plant than a large hardened plant that has stopped growing. 8. Use good watering techniques.احصل على السعر
2012123 The ideal pH range for soil is from 6.0 to 6.5 because most plant nutrients are in their most available state. If a soil test indicates a pH below 6.5, the usual recommendation is for the application of ground limestone. In addition to having the ability to raise pH, limestone contains calcium. Some prefer dolomitic limestoneاحصل على السعر
20151023 If the pH is low, you can increase the calcium concentration relative to magnesium by adding high calcium lime. If the pH is 6.0 or above an effective means of increasing calcium relative to magnesium is adding gypsum. Gypsum is more water soluble than lime at a pH above 6.0 and will give you a faster response.احصل على السعر
