How to grow forsythia to make the roots thicker

You may not know how to grow forsythia to make the roots thicker, let's learn about it together.

How to grow forsythia to make the roots thicker

To make the roots of forsythia grow rapidly thicker, it is important to choose strong seedlings with well-developed root systems. Provide suitable soil, a proper environment, and proper water and fertilizer management to speed up root growth several times. Timely pruning can reduce nutrient consumption and concentrate nutrient supply. Destroying the apical dominance can also achieve good results.

How to grow forsythia to make it thicker

First, root thickening

When selecting seedlings, choose those with thick main roots for planting, which can significantly shorten the time it takes for the roots to thicken.

Root growth is similar to that of leaves and can also be "nurtured" by pruning the roots when repotting, dividing them into multiple levels to promote root growth in multiples, forming a dense network of fibrous roots above the ground, which can increase nutrient absorption.

When planting, try to retain the fibrous roots at a horizontal level, then cut the large roots to create a wound, smooth the wound edges, and during the healing process, more lateral roots will grow from the wound area.

Root thickening is one of the most overlooked issues during planting.

Second, planting soil

Root growth is closely related to the soil environment. Forsythia roots are suitable for loose, breathable, non-compacted, non-waterlogged, slightly acidic soil with light fertilizer. It is recommended to use mixed soil for planting to keep the roots in the best growing environment.

When mixing soil, you can use garden soil, humus, and river sand each in equal parts of 1/3, then add a layer of honeycomb coal powder. This mixed soil is the best for planting forsythia.

In potting forsythia, due to limited soil and pot volume, you can place a large pot at the bottom to allow the roots to spread into the larger pot.

This way, the roots can increase the area of expansion, absorb nutrients from more soil, and the roots can thicken faster.

Third, watering issues

We know that when caring for forsythia, waterlogging can cause root rot, and loss of water can lead to root drying.

Watering forsythia should provide sufficient water for growth while allowing the soil to alternate between dry and wet. Dry soil allows oxygen to enter and promotes smoother root respiration.

Watering should be judged based on the dryness of the surface soil about 3 centimeters deep. When the soil is dry, water thoroughly, following the principle of "not watering until dry, then watering thoroughly."

In spring, watering intervals can be extended by 1 to 2 days. In hot weather, additional watering can be provided through spraying.

Fourth, planting environment

The environment is the most crucial element for plant growth. In a suitable environment, plants will be more flexible in coordinating water, soil, and fertilizer.

The care location should have good ventilation, ample sunlight, and temperatures within the suitable growth range of about 15 to 32 degrees Celsius, with air humidity reaching over 65%.

At home, except for shading during the hot summer, the plant can be cared for in an open area with more sunlight to promote better photosynthesis and increase nutrient absorption efficiency.

If humidity is insufficient, it can be increased through spraying, allowing the roots to better absorb moisture without causing waterlogging.

Fifth, fertilization

When fertilizing forsythia, nutrients must be balanced to promote the growth of both upper branches and roots in the pot.

Fertilization mainly supplements "nitrogen, phosphorus, and potassium." Nitrogen can promote branch growth, while phosphorus and potassium can promote root growth and photosynthesis. It is recommended to use "organic fertilizers" containing complex nutrients.

Regular fertilization involves mixing "composted organic fertilizer" into the soil through loosening, about once a month.

In spring after flowering and in autumn, it is recommended to increase the supplement of organic fertilizer water, diluting animal manure water or rice washing water with water at a ratio of 1:3, adding an extra watering every month.

Sixth, pruning

The main purpose of pruning forsythia is to reduce nutrient consumption and concentrate nutrients for the growth of branches and roots.

After forsythia enters the vigorous growth period, the branches will grow rapidly. Do not prune at this time, as more leaves and better photosynthesis can also promote root growth.

After a period, prune the excess branches.

Forsythia has a strong germination ability, and new buds can appear at any position during the two vigorous growth periods in spring and autumn. The growth of these buds consumes a lot of nutrients.

Therefore, during this rapid growth stage, it is necessary to remove the buds at the base and those in the crown that cannot effectively perform photosynthesis, including hidden buds, axillary buds, and dense buds.
