How Big Can a Cactus Grow? This Giant Cactus at Grandpa's House Is Truly Rare

Cacti look especially cute, like little hedgehogs all over, and the biggest feature of cacti is that they can purify the air, and they are also very easy to grow. Cacti like warm, dry environments, which makes them grow even better, and they like tropical deserts. Today we are talking about a cactus that Grandpa has grown for 20 years. It actually turned into a spirit, growing especially tall, and even when someone offered a high price to buy it, he would not sell.

The growth of cacti is directly related to the soil. Potted cacti generally need calcareous sandy soil or sandy loam with very good drainage and breathability. Leaf mold must absolutely not be used, because it is not suitable. Cacti need reasonable watering to determine their growth state. Cacti should not be watered too much; watering once after the soil dries out completely is enough. In the hot summer, water in the morning.

For cacti, aside from placing a few pieces of horseshoe chips at the bottom of the pot as base fertilizer when repotting, there is no need for too much fertilizing at other times. Cacti are in their peak growing season from April to October. Occasionally add a little phosphorus and potassium fertilizer to ensure sufficient fertility, and they may even bloom. Generally, tall cacti like strong light, while small round ones should not be placed outdoors in the blazing sun in summer.
