How to Grow Golden Larch? Detailed Guide to Cultivation Methods and Precautions

SummaryMethods for growing golden larch: Prepare the growing medium with garden soil, leaf mold, peat soil, perlite or coarse sand, etc. When overwintering, move it indoors for care. In summer, provide appropriate shading; in other seasons, give it plenty of light. During the growing period, keep the potting soil moist, and apply a nitrogen-based fertilizer once a month, but stop fertilizing in winter. Precautions for growing golden larch: Prune leggy branches and buds in time, and generally repot once every 2-3 years.

I. Methods for Growing Golden Larch

1. Soil

(1) Golden larch prefers fertile, loose, well-drained, slightly acidic sandy soil. It can also grow normally in neutral soil, but alkaline soil should be avoided.

(2) Golden larch is a mycorrhizal tree species, so the soil used for planting must contain mycorrhizae to ensure normal growth of the golden larch.

(3) Generally, seedbeds for sowing and cutting propagation need to be mixed with mycorrhizal soil. When transplanting into pots, also carry more of the original soil to ensure the presence of mycorrhizae. Therefore, the substrate can be prepared with garden soil, leaf mold, peat soil, perlite or coarse sand, etc.

2. Temperature

Golden larch likes to grow in a warm environment and is relatively cold-hardy. It can generally tolerate low temperatures of -20°C, but small golden larches are best moved indoors for care when overwintering.

3. Light

(1) Golden larch likes plenty of sunlight, but seedlings are not tolerant of direct strong light, so appropriate shading is needed; otherwise, the seedlings may be scorched.

(2) During summer, when temperatures are high, sunlight is strong and ventilation is poor, leaf tips often become scorched and withered. Therefore, shade from the sunlight around noon is needed, and good ventilation measures should be taken; otherwise, plant growth and development will be affected. In other seasons, give it plenty of sunlight.

4. Watering

(1) Golden larch is not drought-tolerant, so when the potting soil is relatively dry, water it promptly to keep the potting soil moist. Especially when planted in shallow pots, avoid drought in the potting soil even more; otherwise, leaf scorching is likely to occur.

(2) Avoid waterlogging. Excessively wet potting soil will affect plant growth, causing leaf drop and even root rot. After rain, promptly pour out any accumulated water in the pot. After the plant enters dormancy in winter, stop watering.

5. Environmental Humidity

Golden larch likes to grow in a humid environment. During growth, frequently spray water on the branches, leaves and surrounding environment, which helps increase air humidity.

6. Fertilizing

Golden larch is not tolerant of poor, thin soil. During growth, apply a nitrogen-based fertilizer once a month, which helps promote robust branch and leaf growth. During this period, do not apply alkaline fertilizers. When fertilizing, an appropriate amount of ferrous sulfate can be added. During the rainy season, summer high temperatures and winter dormancy, stop fertilizing.

II. Precautions for Growing Golden Larch

1. Pruning

(1) Golden larch has relatively strong sprouting ability. In spring, promptly cut off unnecessary branches and buds. For shaped plants, when newly grown branches and leaves extend and long branches grow longer, keep 1-2 nodes and cut back, which helps maintain the flatness of the branch pads.

(2) Generally, when shaping with metal wire, note that when the metal wire becomes embedded in the bark, promptly remove the wrapped metal wire to prevent affecting the normal growth of the tree.

2. Repotting

During the growing process, repot once every 2-3 years. This can generally be done from after leaf fall in autumn to before bud break in spring, and care should be taken to prevent diseases and pests such as damping-off, stem rot and bagworm moths.
