Hydrangeas are beautiful ornamental plants that grow slowly but have a long lifespan, bringing many wonderful experiences. How to choose a pot suitable for their growth is a question we need to pay attention to when planting hydrangeas.
Pot Size
The size of the pot is a key factor affecting the growth of hydrangeas. Generally, hydrangeas have a well-developed root system, so we need to choose a larger pot. It is usually recommended to use a pot with a diameter of 40-50cm and a depth of about 30-40cm.
Choice of Material
The material of the pot is also an important choice factor. Common materials include ceramic, plastic, and cement. Among them, ceramic pots are aesthetically pleasing but fragile; plastic pots are sturdy and lightweight but not resistant to sun exposure; cement pots are highly durable but heavy. It is recommended to choose a pot that suits your situation.
Drainage Hole Design
Whether the bottom of the pot has drainage holes is also an important consideration. Hydrangeas have high water requirements, and excessive water accumulation can lead to root rot. Therefore, the bottom of the pot must have drainage holes to ensure that water can drain quickly.
Ratio of Potting Soil
Potting soil is one of the keys to hydrangea growth. We recommend a ratio of 4 parts leaf mold, 3 parts garden soil, 2 parts perlite, and 1 part sand, or choose a commercially available succulent-specific soil.
Fertilization Precautions
Hydrangeas need frequent fertilization during their growing period. However, attention must be paid to applying fertilizer in moderation, as excessive amounts can burn the roots and affect growth. Also, when fertilizing, be sure to spread it evenly on the surface of the potting soil, not directly on the leaves.
Avoid Direct Sunlight
Hydrangeas like a warm and humid climate, but they do not like direct, scorching sun. When planting, we need to choose a well-ventilated and shaded place to avoid direct sunlight.
Pay Attention to Watering
Hydrangeas need adequate water to maintain normal growth. But we need to pay attention to the timing and amount of watering each time, avoiding too much or too little. Generally, watering thoroughly once or twice a week is sufficient.
Essential Tools
When planting hydrangeas, we need to have tools such as hoes, watering cans, and fertilizers on hand. These tools make it convenient for us to manage and care for the hydrangeas at any time.
Regular Pruning
Hydrangeas grow slowly, but they become lush after the tree shape matures. We need to promptly remove dead branches, dead leaves, and unnecessary branches to ensure the normal growth of hydrangeas.
Regularly Replace Potting Soil
Hydrangeas need to have their potting soil replaced regularly. Generally, replacing it once in spring and autumn each year is sufficient to ensure the fertility and aeration of the potting soil.
Avoiding Pests and Diseases
Hydrangeas are susceptible to pests and diseases. We need to check them regularly and take timely measures for prevention and control if harmful organisms are found.
Pay Attention to Transplanting
Hydrangeas are plants that are difficult to transplant, and improper transplanting can easily affect their growth. Therefore, attention must be paid to operational techniques and handling methods during transplanting.
Keep Moist
Hydrangeas like a humid environment, so we need to spray water regularly to maintain the moisture of the potting soil and promote the normal growth of hydrangeas.
Moderate Pruning
The pruning of hydrangeas should be moderate; otherwise, it will affect the shape of the tree and the quality of the flowers. Generally, we only need to regularly trim overly long or dead branches, and do not over-prune.
Choosing a pot suitable for hydrangea growth is very important for the plant's development. During the planting process, we need to pay attention to aspects such as the ratio of potting soil, fertilization, watering, and pruning to ensure the hydrangeas are in a good growth state.
