The important period of fertilization for mallow is its flowering period. Its flowering period is relatively long, so it needs sufficient nutrients to maintain, and its flowering quantity is also relatively large. At this time, if the fertilizer supply is insufficient, it will not only lead to the flower thinning, but also cause certain damage to the plant. At the beginning of May, we will start to apply fertilizer. We can choose fertilizer containing nitrogen and phosphorus. It will be applied once every 15 to 20 days or so. In June, we will apply phosphate fertilizer once a month to twice a month. Until October, the flowers will all wither, so that the number of flowers will increase.
Before fertilization, the soil should be dried, and then the soil can be loosened properly. In this way, the plant can absorb the nutrients in the fertilizer better.
If the fertilizer concentration is lighter, it can shorten the time of fertilization. If it is thicker, the next day of fertilization will be watered, so as to avoid the accumulated fertilizer from damaging the plants.
In case of overcast and rainy days, reduce fertilizer application properly, or suspend fertilizer application, because the excessively wet soil is very harmful to plant growth.
The best time to apply fertilizer is in the morning or in the evening. Do not apply fertilizer at noon.
When fertilizing, try to pour it slowly along the edge of the basin or away from the soil, so as to reduce the damage of fertilizer to plants.
