Light Requirements
Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve requires moderate to high light intensity to grow. The plant prefers bright, indirect light with at least six hours of direct sunlight per day. Too much direct sunlight can cause the leaves to turn yellow and brown.
Temperature Requirements
The plant grows best in temperatures between 15-25°C (59-77°F). If the temperature exceeds 30°C (86°F), the plant may become dormant, and growth may slow down. At temperatures below 10°C (50°F), the plant may stop growing entirely.
Soil Requirements
The plant prefers nutrient-rich, well-draining soils with a pH range between 6.0-7.5. The ideal soil texture for Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve is loamy and sandy. The plant can grow in both sterile and organic soils. However, heavy clay soils can cause root rot if not adequately drained.
Cultivation Methods
Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve thrives in bright to moderate light with a pH ranging from 6.0 to 7.5. It requires a nutrient-rich substrate and a well-draining soil mix. This plant can be grown emersed or submersed depending on the preference of the gardener. If grown submersed, it is best to start with fully submerged plants and gradually increase the water level over several weeks.
Watering Needs
This plant prefers water that is slightly acidic to neutral and soft to moderately hard. It is essential to maintain consistent water quality, including temperature, circulation, and adequate light exposure. If the water parameters are not ideal, it can cause the plant to become stressed, leading to poor growth and development. Additionally, the plant requires frequent water changes to maintain water quality.
Fertilization
Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve requires regular fertilization to thrive. It is essential to use a good quality liquid fertilizer, high in macro and micronutrients, with a balanced NPK ratio. Fertilizing should be done at least once a week to boost plant growth and promote vibrant coloration. It is also recommended to use root tabs or substrate fertilizers to support the plant's root system.
Pruning
Pruning is essential to keep Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve healthy and looking attractive. Regular pruning will help to prevent overcrowding, promote new growth, and remove any dying or decaying leaves. It is best to trim the plant's stems regularly to encourage bushier growth and reduce the chance of leaves falling off. Additionally, you should remove any dead or unattractive leaves, which can cause decay and hinder the plant's growth.
Propagation of Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve
Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve can be propagated by several methods including seed germination, stem cuttings, and division.
Seed Germination
Seeds of Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve can be collected in the fall and stored in a cool, dry place until spring. In the spring, the seeds can be sown in a seed-starting mix and covered lightly with soil. The seedlings should be kept moist and warm until they are large enough to be transplanted into individual pots.
Stem Cuttings
Stem cuttings of Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve can be taken in the spring or early summer when the plant is actively growing. Cuttings should be taken from healthy stems and should be approximately 3-4 inches in length. The bottom end of the cutting should be dipped in rooting hormone and then planted in a moist rooting mix. The cutting should be kept moist and warm until roots develop, and then it can be transplanted into a larger pot or directly into the ground.
Division
Myriophyllum exalbescens Fern. var. magdalenense (Fern.) A. Löve can be propagated through division in the spring or fall. The plant should be carefully dug up and divided into several smaller clumps using a sharp, clean knife. Each clump should have a healthy root system and several stems. The divided clumps can be planted in pots or directly in the ground.
Disease and Pest Management for Myriophyllum exalbescens Fern. var. magdalenense
Myriophyllum exalbescens Fern. var. magdalenense is a hardy aquatic plant that is resistant to most diseases and pests. However, it can still be vulnerable to certain problems that can affect its growth and overall health. Here are some common diseases and pests that can attack this plant, along with suggestions on how to manage them:
Diseases
1. Algae: This plant can be susceptible to different types of algae, which can quickly cover the leaves and stems, blocking sunlight and nutrients. To control algae, it is important to maintain good water circulation, avoid overfeeding fish, and remove any dead plant material from the bottom of the tank. Also, introducing algae-eating fish or snails can be beneficial.
2. Fungal infections: Fungi can cause leaf spots, stem rot, and other damages. To prevent fungal infections, it is essential to keep the tank clean and hygienic, avoid overcrowding, and provide adequate light and aeration. If fungal infections persist, you may need to use an antifungal treatment.
Pests
1. Snails: Snails can be a common problem in aquariums and can multiply rapidly. They can damage the leaves and roots of the plant. To control snails, avoid overfeeding and keep the tank clean. You can also manually remove them or introduce snail-eating fish or snails.
2. Fish: Some fish species can also damage the plant by eating leaves or uprooting the stems. To prevent this, choose compatible fish species and provide enough hiding spots and vegetation. Also, avoid overstocking and overfeeding, as this can cause aggression and stress.
In conclusion, Myriophyllum exalbescens Fern. var. magdalenense is a low-maintenance plant that can resist many diseases and pests. However, it is important to maintain good water quality and hygiene, prevent overfeeding and overcrowding, and choose compatible aquarium mates to ensure its optimal growth and health.
