How to Grow Hydrangea? Detailed Guide to Cultivation Methods and Precautions
SummarySoil: You can mix leaf mold, garden soil, river sand and cake fertilizer in a certain ratio to make nutrient soil. Sterilize the soil before potting, and water thoroughly after potting. Environment: Hydrangea prefers shade over sun, so it is best placed in a cool, ventilated spot. Watering: Water more in spring and summer to keep the potting soil moist; in autumn and winter, light misting is enough. Fertilizing: Apply 1 round of organic fertilizer every half month; apply more phosphorus and potassium fertilizer during flower bud differentiation and bud formation. Precautions: Around March in spring, prune off diseased and dead branches.
I. Methods for Growing Hydrangea
1. Choosing Soil
When growing hydrangea in a flower pot, you can use leaf mold : garden soil : river sand : cake fertilizer in a ratio of 4:3:2:1, then mix them into nutrient soil. Sterilize the soil before putting it into the pot, and water it thoroughly after potting.
2. Cool and Ventilated
Hydrangea prefers shade and does not like sun, so when growing it, place it in a cool, ventilated spot. In winter it can be kept in a spot with diffused light; in the other seasons, you can move it out to bask in the sun each morning before the sun is fully up, because going without light for a long time will also cause poor growth and development in hydrangea.
3. Watering Method
In spring and summer, water more to keep the potting soil moist. Especially during the high-temperature period in summer, water once in the morning and once in the evening; at noon, provide appropriate shade, and watering can be skipped during this time. During the dry periods of autumn and winter, mist the hydrangea appropriately. Generally in winter it is in a dormant period, so light misting is fine, but do not overwater, to avoid breaking the hydrangea's dormant period.
4. Fertilizing in Moderation
While growing hydrangea, apply 1 round of organic fertilizer about every 15 days. In the early growth stage, apply more nitrogen fertilizer; during flower bud differentiation and bud formation, apply more phosphorus and potassium fertilizer. During this time, fertilize in moderation according to the different stages, so that the hydrangea will grow more luxuriantly.
II. Precautions for Growing Hydrangea
1. Proper Ventilation
When growing hydrangea indoors, often open doors and windows for ventilation, and you can also move it to a balcony for a period of time, to avoid various pests and diseases in the hydrangea caused by indoor air not circulating for a long time. Especially during the summer thunderstorm season, ventilation needs to be strengthened even more.
2. Acidic Soil
Choose suitable soil for growing it. Hydrangea likes acidic soil. If it is grown in alkaline soil, it will lead to poor growth and development, resulting in yellowing leaves and even death.
3. Spring Pruning
Around March in spring, prune the hydrangea. During this time, cut off diseased branches, dead branches and weak branches, keep 3-5 strong main branches, and just cut them back; keep about 3 buds per branch, so that more new shoots and buds will sprout.
