Common Names
The plant is commonly referred to as the Transvaal glad or pink glad due to its pink-colored flowers.
Uses
The Gladiolus permeabilis D.Delaroche subsp. permeabilis has significant ornamental value. It is popular among flower enthusiasts and gardeners for its beautiful pink flowers, which make it an attractive addition to gardens and landscapes.
General Appearance
The Gladiolus permeabilis D.Delaroche subsp. permeabilis can grow up to 45 centimeters in height. It produces beautiful pink flowers with six petals. The leaves are narrow and long, reaching up to 55 centimeters in length. They have a deep green color and are arranged in a sword-like shape. The plant blooms during the summer months, typically from December to February.
Light Requirements
Gladiolus permeabilis D.Delaroche subsp. permeabilis requires full sunlight for optimal growth. Direct sunlight for at least 6-8 hours a day is needed for proper development of the plant.
Temperature Requirements
The suitable temperature range for Gladiolus permeabilis D.Delaroche subsp. permeabilis growth is between 15°C to 25°C. A well-balanced temperature ensures that the plant grows healthy and produces better flowers. The plant can tolerate mild frost, however, extreme cold can be fatal to the plants.
Soil Requirements
Gladiolus permeabilis D.Delaroche subsp. permeabilis prefers well-draining soil that is rich in organic matter. The soil should have a pH level between 6.0 to 7.5. The plant can grow in sandy loam, loam, clay loam, or any well-draining soil types. Avoid planting in waterlogged or heavy clay soils as they can cause rotting of the bulbs. Before planting, loosen the soil and mix it with compost for better nutrient availability.
Cultivation of Gladiolus permeabilis D.Delaroche subsp. permeabilis
Gladiolus permeabilis D.Delaroche subsp. permeabilis is a perennial plant that grows from corms. It prefers well-drained soils that are rich in organic matter. The plant requires full sun exposure for optimum growth, so choose a spot that receives at least six hours of direct sunlight each day. It is best to plant them in the fall.
Watering Needs of Gladiolus permeabilis D.Delaroche subsp. permeabilis
The plant requires frequent watering, especially during the growing season. It is best to water the plants in the morning or late afternoon, avoiding watering during the hottest part of the day. Always water the plants at the base, avoiding wetting the foliage, which can lead to fungal diseases.
Fertilization of Gladiolus permeabilis D.Delaroche subsp. permeabilis
Fertilize the plants before planting and then every two to three weeks during the growing season. Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. You can also add bone meal or fish meal to the soil for added nutrients.
Pruning of Gladiolus permeabilis D.Delaroche subsp. permeabilis
Remove the faded flowers to encourage the plants to produce more blooms. Once the plants have finished flowering for the season and the foliage has begun to yellow and die back, cut back the stems to the soil level. This will allow the corms to rest and prepare for the next growing season.
Propagation of Gladiolus permeabilis D.Delaroche subsp. permeabilis
Gladiolus permeabilis D.Delaroche subsp. permeabilis can be propagated using various methods. Some of the common methods of propagation for this plant are:
Propagation through Cormlets
The easiest and most common way to multiply this plant is by using cormlets which are small corms produced by the parent corm. The cormlets can be separated from the parent corm once they reach an adequate size and are stored until the planting season. When planting, ensure the cormlets are planted shallowly with the bottom barely covering the soil surface. This ensures that they do not rot in excessively wet soil.
Propagation through Corm Division
The parent corms can also be divided to produce more plants. It should be done when the corms are in the dormant phase, usually during autumn. After lifting the parent corm, remove the suckers that develop around it. Make sure that each corm has at least one sound eye. After that, these divisions can be planted.
Propagation through Seeds
Propagation using seeds is not the best way to multiply the plant as the resulting plants may not be true to the parent plant. The seeds must be sown in the spring, and they usually take about three years to mature and start flowering. When sowing, it is essential to ensure the soil is well-drained, light, and fertile.
Regardless of the propagation method used, it is important to ensure that the planting site has adequate sunlight and that the soil is well-drained, loamy, and rich in nutrients. With the right care and attention, Gladiolus permeabilis D.Delaroche subsp. permeabilis can be easily propagated and grown in a garden or greenhouse.
Disease Management
Gladiolus permeabilis D.Delaroche subsp. permeabilis can be susceptible to various diseases, including:
- Fusarium corm rot: This fungal disease can infect the corms and cause them to rot. Affected corms need to be destroyed, and the soil should be treated to prevent further infections.
- Botrytis blight: A fungal disease that attacks the leaves and flowers, causing them to rot. It spreads rapidly in humid conditions. Removal of the infected parts and proper plant spacing can help manage the disease.
- Black root rot: This disease is caused by a soil-borne fungus that infects the roots and causes them to rot. The infected plants eventually wilt and die. Proper soil drainage and the use of disease-free corms can prevent the disease.
To manage gladiolus diseases, it's essential to maintain good cultural practices. This includes planting disease-free corms in well-draining soil, proper watering and providing adequate air circulation. Additionally, you can use preventive measures such as fungicide sprays and crop rotation to manage any possible recurring disease outbreak.
Pest Management
Gladiolus permeabilis subsp. permeabilis is sometimes affected by certain pests that include:
- Thrips: These are tiny insects that feed on plant sap, damaging leaves, and causing brown streaks on the flowers. Insecticidal soap or neem oil spray can help manage this pest.
- Spider mites: These tiny mites can cause foliage discoloration and sometimes lead to death. Regular misting and avoiding overcrowding of the plants can help manage the pest.
- Corm maggots: These are the larvae of flies that burrow into the corms, causing them to rot. The use of floating row covers during the growing season could prevent the pest from attacking the plants.
To manage pest attacks, early detection, isolation and treatment are the primary methods. You can remove infected corms and treat the soil with an insecticide or fungicide. Also, proper sanitation and regular monitoring for any pest activity can help you identify the problem and take the necessary measures before the issue becomes severe.
