Boston Fern Growing Methods and Cultivation Techniques Explained in Detail

Boston Fern Growing Methods and Cultivation Techniques

Generally place in a spot with bright indirect light indoors for cultivation; it must not be exposed to strong direct light, but it also should not be kept in a dark place. The optimal growing temperature is 15-25°C, and in winter it can safely overwinter above 10°C.

Although it is drought-tolerant, it still needs sufficient moisture, and it should not be too wet or too dry; the potting soil should be kept consistently moist. In summer, water 1-2 times a day and frequently spray the leaf surface with water. It does not need much fertilizer; during the growing season, applying a thin, well-rotted cake fertilizer once every 4 weeks is enough. Do not use quick-release chemical fertilizers. When fertilizing, never let it stain the leaves, so as to avoid damage.

For potting, use a mixed growing medium of leaf mold, river sand and garden soil. If conditions allow, using sphagnum moss as the growing medium will produce even better growth. Repot once every other year in spring.

For outdoor cultivation of Boston Fern, mix about half (by volume) of expanded plastic artificial soil into ordinary growing soil and stir well. For indoor potting, you can use pure expanded plastic artificial soil, which is lightweight, clean and hygienic. Boston Fern is best cultivated in a shade shed, with a layer of shade cloth covering the shed. Adding a layer of colorless film on top is even better, as it both prevents rain from soaking it and avoids direct sunlight. During the growing season, water once a day, preferably by drip irrigation, so that water droplets do not get on the leaves and cause them to turn yellow and rot. In hot summer, you can also spray water around the potted plants to increase humidity. In winter, water should be controlled appropriately, keeping it merely moist. During the growing season, nitrogen fertilizer must be applied as a top dressing. For outdoor cultivation, apply thin organic fertilizer water twice a month, and never contaminate the leaves; for indoor cultivation, supplement once every 2 months or so with a nutrient solution mainly based on nitrogen. To ensure a beautiful plant shape and promote air circulation, withered and yellow old leaves should be pruned away along with shaping.

Cultivated Varieties

Fine-leaf Boston Fern has slender leaves, Rough-split Boston Fern has coarse serrations along the leaf margins, and Crown-leaf Boston Fern.

Planting Techniques

Production standard: 18cm pot, height 30-40cm, crown width about 60cm, growth cycle 10 months.

Substrate preparation: use loose, well-draining and well-aerated imported peat of the Klasmann 10-30mm grade. Crush the peat, add water and mix well (standard for adding water: after mixing with water, squeeze a handful of peat tightly and water seeps out from between the fingers). Then it is ready for potting. A 12cm pot uses about 350ml of peat per pot, and one 300-liter package of imported peat can fill about 800 cups.

Potting requirements: choose high-quality seedlings from professional production, with seedling height 7-8cm, crown width 4-5cm, free of pests and diseases, and free of withered or yellow leaves.

Potting: first plant in 12cm pots, 1 clump per pot, for 3-4 months. Then transfer to 18cm pots, and after 6-7 months of growing they can be shipped.

Daily Care

Water and fertilizer management: Boston Fern should be kept with moist potting soil, and during the growing season water should be supplied abundantly. Although the soil should be kept moist, for Boston Fern, if it dries out frequently, the lower leaves will wither and drop off.

Temperature management: the suitable temperature for Boston Fern is 18°C-35°C. Growth is poor both above 35°C and below 15°C. In winter it must not go below 5°C. Winter care requires heating equipment. If there is no heating facility, double-layer insulation facilities can be used. In winter, when the temperature drops to 22-24°C in the afternoon, the greenhouse should be sealed promptly. Summer care requires cooling equipment (exhaust fan and water curtain). If there is no heating or cooling equipment, shading and ventilation should be strengthened at noon in summer, and leaf-surface water and ground water should be supplemented to achieve the purpose of cooling. At the same time, long-distance multi-span greenhouses should not be used; independent single-roof sheds should be used instead.

Humidity management: it likes a high-humidity environment and is not tolerant of dryness. During care, water should be sprayed frequently on the plants and the growing environment to increase humidity. The suitable humidity is about 75%-80%. Excessive dryness will cause the leaf margins to turn yellow, or even the entire leaf to turn yellow.

Light management: Boston Fern likes a warm, semi-shaded environment and is suited to indirect light. It must not be exposed to direct sunlight, otherwise it easily wilts and curls. 15 days after planting, controlling light at 2000-3000Lux is more suitable for the growth of small seedlings. In the first month after planting, overall light control at 3000-4000Lux is more suitable. In the second month after planting, overall light control at 5000-6000Lux is more suitable. Afterwards, overall light control at around 7000-8000Lux is more suitable. In winter, according to actual conditions, it can be controlled at 10000-15000Lux. Excessive light causes the plant's leaf margins to scorch and drop off, the leaves to curl, and growth to be hindered.

Fertilizer: use Peters Professional 20-20-20 water-soluble fertilizer, calcium nitrate, and potassium nitrate.

Boston Fern Growing Methods and Precautions

1. Soil Requirements

For potting, use a mixed growing medium of leaf mold, river sand and garden soil. If conditions allow, using sphagnum moss as the growing medium will produce even better growth. Repot once every other year in spring.

2. Watering Method

Water with the principle of keeping it moist. Boston Fern has relatively strict water requirements; it should not be too wet, nor too dry, and it is best to keep the potting soil consistently moist. In summer, you can spread some wet sand on the ground around the flowerpot and spray some water to increase the environmental humidity. In winter, when room temperature is low, watering should be reduced, and keeping the soil slightly moist is appropriate.

In summer, water once every 1-2 days, but in winter the amount of watering should be controlled. Spray water on the plant and the surrounding environment 2-3 times a day to increase air humidity. In autumn and winter, water again when the soil is half dry. If the plant wilts due to lack of water, you can soak the whole pot in water to revive it, and spray the leaves more. If it still has not recovered its uprightness after soaking for 24 hours, you may as well cut off all the leaves to promote the growth of new leaves. Boston Fern's root system is weak and extremely sensitive, so the fertilizer concentration should not be too high, otherwise it is easily damaged. But ferns also all like fertile, water-retentive soil, so the best way is to first add well-rotted barnyard manure when potting, and later apply a thin fertilizer as a top dressing. When fertilizing, avoid letting the fertilizer liquid stain the leaves. If it is accidentally stained, immediately spray clean water to rinse it off. In addition to using growing soil plus well-rotted compost as the growing medium, coarse sand can be added to avoid excessive stickiness, and remember to first put coarse gravel and small stones at the bottom of the pot as a base layer.

3. Repotting

Generally repot once every 1 year in spring. For the potting soil, choose a mix mainly of leaf mold with a small amount of river sand added. In places where conditions allow, if materials such as moss can be used as the growing substrate, the growth will be even better. In addition, Boston Fern. It likes a warm environment, and the optimal growing temperature is 15-25°C; the overwintering temperature should not be lower than 5°C. In winter, the room temperature should preferably be kept above 6°C. If the lower old leaves are found to be withered and yellow, they should be pruned away promptly to keep the plant shape beautiful.

Propagation of Boston Fern

In early summer, the stolons growing from the plant will grow rapidly and produce small rooted plantlets. In summer, choose vigorous plants, then cut off the small rooted plantlets mentioned above and plant them separately. When dividing along with repotting, first invert the plant and knock it out of the flowerpot, shake off all the old soil, then cut it into several clumps and plant them separately, afterward placing them in a shaded spot; after about a week they can be given normal care. When potting, the soil can be a mixed growing medium of leaf mold, river sand and garden soil. If sphagnum moss can be used as the growing medium, that would be even better.

Whether Boston Fern Is Suitable for Indoor Cultivation

As mentioned above, Boston Fern is not only non-toxic, but can also purify the air, so it is very suitable for indoor cultivation, helping people absorb harmful gases and playing a certain role in ensuring air quality and human health. Therefore, Boston Fern is especially suitable for placing in newly renovated new homes. In addition, placing Boston Fern indoors for cultivation can also play a role in beautifying the home environment and decorating the room. The tender green leaves look very beautiful and pleasing to the eye, making people feel the breath of spring and thus relax. It is precisely because the mood is relaxed that sleep quality is also improved, so Boston Fern can also improve people's sleep quality.

The key points for growing Boston Fern are nothing more than light, soil, water and fertilizer, while also paying some attention to repotting and propagation, and then relatively good growing results can be achieved. In fact, growing Boston Fern should not be difficult; after all, before people cultivated them, ferns were just a kind of wild grass in the mountains.
