Cycas, also known as Phoenix tail pine, Phoenix tail banana, is a wood with very high wood density, which will sink immediately when placed in water. Cycas can flower, but it needs varieties that are more than ten years old, such as those planted in northern China rarely bloom. Let's see if Cycas is a tree or shrub plant. What are the key points of water and fertilizer management?

Is Cycas a tree or a shrub?

Cycas are evergreen trees. Cycas like light, slightly tolerant of semi-shade. Love warmth, not very cold. It likes fertile, moist and slightly acidic soil, but it can also tolerate drought. Slow growth, more than 10 years of plants can flower.

Su Tie tree shape quaint, trunk stout, hard as iron; feather clean smooth light, evergreen, for precious ornamental tree species. The south is planted in front of the court steps and lawn; the north is suitable for large potted plants, decorated with courtyard corridors and halls, especially beautiful.

There are three cultivation methods: sowing, tillering and cutting. Tillering bud cultivation is the most common and can be carried out from spring to autumn, with the best effect in spring. Specific operation: When the old plant stems grow tillers and buds as big as eggs, cut the mother plant with a sharp knife in March to April of early spring, cut as little as possible to hurt the stem skin, cut off the leaves, put it in the shade for about 7 days, wait for the wound to dry slightly, transplant it into the culture soil, pour water once, put it in the shade, keep it at 27~30℃, take root in 45 days, and grow leaves at the same time.

2. What are the key points of cycad water and fertilizer management?

The soil for planting cycas is fertile and slightly acidic sandy loam; 2 parts of loose and fertile moldy soil with good drainage and permeability, 1 part of garden soil, and appropriate sawdust or cinder, plant ash and phosphorus fertilizer are added for pot planting.

Watering timely suitable for planting more than three years old cycas, as long as not encounter extraordinary drought, generally can not water or less watering. Potted cycas, watering more need to be timely and appropriate, when the surface 2~3cm of soil dry white, not sticky hands, soil and flower bowl contact a circle of cracks, you can water, master the principle of "do not dry, do not water, water to penetrate", avoid ponding in the basin. If rotten roots and stems occur, the rotten parts should be removed in time and replanted after 1-2 days in a ventilated place.

In addition to the fleshy roots with hair, there are coral-like roots with nitrogen fixation, which can promote the growth of plants. Cycas avoid applying large amounts of nitrogen fertilizer. Available decomposed chicken manure, cake fertilizer and a small amount of phosphate fertilizer as base fertilizer, and fully mixed with the subsoil. If the soil is high in humus. Base fertilizer should be reduced. Topdressing can be applied after rapeseed cake is fermented with water, the concentration is controlled at 1%-2%, and a small amount of ferrous sulfate (concentration is 0.1%, if there is no ferrous sulfate, iron filings or small scrap iron pieces can be placed on the soil surface). Pot can also be fermented or unfermented cake fertilizer scattered on the surface of the pot (or mixed with topsoil). Through watering, it plays the role of topdressing. From September to October, apply 0.5% potassium dihydrogen phosphate solution for 1~2 times.
