Why don't cacti bloom?
Today's tip on plant care: understanding why cacti don't bloom and the essential conditions for cacti to bloom, here are the details:
Why doesn't the cactus at home bloom? Seeing other people's cacti online that are already blooming, while the cactus at home shows no sign of change, is it because of a lack of fertilizer?
Cacti blooming is mainly influenced by two factors: one is the local temperature, and the other is the root system of the cactus, which has nothing to do with fertilizer.
Many people who encounter problems with their plants turn to the internet for solutions. For example, when a cactus doesn't bloom, they search for what might be wrong. Many gardening bloggers recommend using fertilizer, suggesting that not blooming is due to a lack of fertilizer. This is completely false. Many gardening bloggers often promote fertilizer sales, constantly mentioning it, but in reality, cacti generally do not need to use fertilizer.
Even if we grow cacti at home using pure granular soil and meet certain growth conditions, they will still bloom. There is no significant relationship between fertilizer and cacti blooming. Therefore, fertilizer has nothing to do with the blooming of cacti.
Why don't cacti bloom?
Generally speaking, based on ensuring the health of the cactus root system, cacti in the south can bloom from April to May every year, while those in the north need to wait until June to July. Blooming is always affected by temperature. The local temperature needs to rise to between 25 and 30 degrees Celsius for cacti to bloom.
There is a significant temperature difference between the north and south of our country. The south is warmer, and the north is cooler. Moreover, the temperature in the north is exceptionally low this year, so cacti may need to wait until June to bloom.
The blooming cacti we see online are likely mostly from the south or those grown in greenhouses. In higher-temperature environments, cacti are already blooming. If your cactus doesn't bloom, it might be because the temperature has not reached the required level.
