Olga Bay larch or Olgan larch (Larix olgensis) a species of larch is named after Olga Bay in the Sea of Japan. The common name in Japanese language is 満洲唐松 (Manshu'u Kara-matsu). The common name in Chinese is 黄花落叶松 (pinyin: huang hua luo ye song). This species occurs in Central Sikhote-Alin and rarely occurs in North Korea and Jilin and eastern Heilongjiang provinces of China between 500 and 1100 metres in elevation. This deciduous coniferous tree grows to 25–30 meters tall with a trunk reaching a meter in diameter at breast high with gray to gray-brown bark with flaking and scaly fissured bark. Its leaves are needle-like dark-green 1.5–3 cm long and 1 cm wide. The reddish purple or violet cones mature to light brown sometimes tinged with purple and range from 18 to 25 mm long. Pollination occurs in spring with seeds maturing in fall-fall. It grows in mountains and on moist slopes and in swamps. The timber has many uses in construction and for wood fiber. The trunk is used to produce resin while the bark is used for tannins. Olga Bay larch is sometimes treated as a variety of Dahurian Larch Larix gmelinii var. olgensis (Ostenf. & Syrach). Larix olgensis is a vulnerable species.

Common issues for Olga bay larch based on 10 million real cases
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
Not enough water. A lack of water will lead to dry plant tissue.
Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention involves providing your plant with the proper environment.
Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
Extreme heat and dry weather (when growing outdoors)
Grow lights or indoor lighting that is too bright or intense for the type of plant
Using fast-draining growing media such as sand

If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Prevention
Always check the soil before watering. If the top inch of soil feels moist, though not wet, the watering is perfect. If it’s dry, water it immediately. If it feels soggy, you avoid watering until it dries out a bit more.
Also, make sure the lighting is sufficient for the species. Plants grow faster and need more water when there is intense light or lots of heat. Being aware of these conditions and modifying them, if possible, is a good way to prevent underwatering. Many container plants are potted in soil mixtures mean to be well-draining. Adding materials that retain moisture, like compost or peat moss, can also prevent these symptoms.
Other tips to prevent underwatering include:
Choose pots with adequately-sized drainage holes
Avoid warm temperatures
Use large pots with additional soil (these take longer to dry out)
Avoid terracotta pots, which lose water quickly
