There are appropriate scattered light on the side of the window every day, such as more than 1 to 3 hours of soft light every day, if you want to plant some flowering plants, the first choice is the common white palm, red palm, mini rock tree, large rock tree and other semi-shade-tolerant flowering plants.

If the balcony or window sill lacks light, but the ventilation is still good, and the environment is relatively warm and cool, then you can try planting several flowering plants common to bitter lichen, especially the African viola, viola (cape primrose) and large rock tree.

For example, the big rock tree to be mentioned today, even if it is a relatively common shade-tolerant flowering plant, is also very small, and will not be as popular as the green lotus, the fortune tree, the red palm, and the white palm.
There are also several different varieties of large rock trees, the flower color is relatively rich, there are common pink, purple, red, white and various mixed color varieties, its flowers are trumpet-shaped, the flowers are particularly large, the leaves are relatively large, there are many fine white small fluff on the leaf surface, which feel special to the touch.
Large rock tree is a perennial herb, as the plant gradually grows and matures, the bottom will slowly grow a larger tuber, if you want to reproduce later, you can cut its tubers (the cutting tool should be sharp and disease-free), you can reproduce in separate plants.
If the large rock tree is properly maintained, the environment is suitable, it can continue to flower throughout the year (mainly concentrated in summer), and the autumn environment can continue to breed flowers, it will prefer a warm and cool environment, afraid of excessive high temperature and strong light exposure, and give more scattered light.
1. Fertilize frequently
Flower lovers should also remember that the big rock tree is a flowering plant, if you want it to flower more, you must fertilize frequently, it does not like poor soil, and it is necessary to apply thin fertilizer diligently.
As long as the temperature can be maintained at 15 to 27 degrees, you can supplement the phosphorus and potassium fertilizer every one or two weeks to ensure that it blooms better, you can use one or two kinds of flower-promoting fertilizer to spray alternately, such as alternating spraying with huaduoduo No. 2 and potassium dihydrogen phosphate, pay attention to the concentration when fertilizing, generally use 1000 ~ 1500 times is relatively safe (one milliliter or a gram of agent mixed with 1000 ml of water), you can directly spray the back of the foliar leaves, and then pour into the pot soil, which can ensure that the fertilizer absorption is better, However, it is necessary to pay attention to operating in a well-ventilated environment and avoid being raised in a closed environment.
2. Potting soil selection
The soil for planting large rock trees should be fertile and loose enough to ensure that the soil is slightly acidic, such as the use of common peat soil, coarse coconut shell, perlite, can be appropriately mixed with some bark, to ensure that the soil is breathable enough, drainage is also better, can be appropriately mixed with some slow-release fertilizer and sheep manure (for seedlings, be cautious with fertilizer), to ensure that the soil has appropriate fertility.
Planting potted large rock tung, do not use too large pots, slightly compact pots can better manage the dry and wet of the potting soil, as its tubers continue to grow, you can choose to change pots in the spring and autumn.
3. Why do buds fall (buds)?
When the big rock tree is flowering, the flower buds are continuously emerging, one after another continues to open, and some of the potted flower buds of the big rock tree have withered before they have bloomed.
In this case, it is necessary to remove the residual flowers in time, and to clean up, pay attention to increasing a little sunlight, and do not expose to the sun. In addition, be careful not to spray water on the flower buds and supplement some phosphorus and potassium fertilizers, such as potassium dihydrogen phosphate every other week. Pay attention to reasonable watering, water the pot soil slightly dry, and do not let the soil dry for too long.
4. Watering and precautions
Before each watering, to check the dryness and wetness of the potting soil, the soil surface is about 3 cm dry, you can water it thoroughly, if the ventilation is not good, lack of sunlight, try to only pour into the potting soil, you can open the leaves to water, or directly dip the pot.
When maintaining potted large rock trees, we must pay attention to the prevention of diseases and insect pests in advance, the soil planted should be clean, avoid planting with old soil, and secondly, it is necessary to ensure that the leaf surface does not often retain water, if it is rain or spray water, it is necessary to ensure that the water on the leaves can be volatilized in time, otherwise it is easy to cause leaf rot, infection with germs, and even the stems are directly withered.
Potted maintenance of the big rock tree to avoid water, the soil can not continue to be wet, let alone water. If there is a tray at the bottom of the pot, be sure to avoid standing water on the tray (pour it out in time), otherwise it will cause the roots and tuber at the bottom to rot.
