Matters needing attention in the process of family vegetable planting:
First, watering: According to the growth needs of vegetables, we usually water them twice.
Second, fertilization: when your vegetables are not growing well, you can properly pour some nutrient solution or organic fertilizer.
If vegetables need to be transplanted, wait until the seedlings are transplanted before pouring nutrient solution.
If vegetables are sown directly without transplanting, tap water should be poured first to keep the soil moist, and then nutrient solution should be used after seeds germinate and seedlings grow.
Although various plants have different requirements for water, it is more appropriate to irrigate nutrient solution once a day. If it is leafy vegetables, you can water the nutrient solution twice a day.
Less nutrient solution was poured in the early growth stage, but more nutrient solution was poured in the fruiting stage.
It is recommended to thoroughly filter and clean the planting containers with tap water at least once a week to remove the unused fertilizers accumulated in the containers. The specific method is to pour enough water into the container to form gravity drainage at the bottom. This measure can prevent the accumulation of harmful substances in the medium.
Sometimes vegetables can be watered with nutrient solution containing trace elements. You can choose a water-soluble fertilizer containing iron, zinc, boron and manganese and follow the instructions on the label.
Note: Abuse of nutrient solution may lead to the risk of excessive nitrate in vegetables.
