written by Peter

Houseplant Myths Debunked: Expert Advice for Thriving Indoor Greenery

Myth 1: Don’t Repot Plants in Winter

Contrary to popular belief, you can repot plants year-round. Winter dormancy doesn’t apply to all plants, and if your plant needs more space or a more aesthetically pleasing pot, don’t hesitate to repot it. To offset any potential stress, consider using a grow light to supplement natural sunlight.

Myth 2: Succulents Are Unkillable

While succulents are relatively low-maintenance, they can succumb to neglect. Overwatering or inadequate lighting are common causes of succulent demise. Ensure they receive plenty of light and avoid excessive watering.

Myth 3: There Are ‘Easy’ and ‘Hard’ Plants

The notion of ‘easy’ or ‘hard’ plants is a misconception. All plants have specific needs that must be met to thrive. By understanding their individual requirements and providing the right environment, even supposedly ‘hard’ plants can flourish.

Myth 4: You Should Have a Plant in Every Room

Adding plants to every room for aesthetic purposes can backfire. Consider the plant’s specific needs, such as lighting requirements, before placing it in a particular location. Prioritizing aesthetics over plant health can lead to premature plant death.

Myth 5: You Can’t Reuse Soil

Reusing soil is not only possible but also beneficial. While some nutrients are lost with each reuse, regular fertilization can compensate for this. Reusing soil saves money and reduces waste.

Myth 6: Bigger Pots Are Better

While it may seem logical that larger pots provide more growing space, this isn’t always the case. Oversized pots can lead to overwatering and root rot, especially if the soil does not drain properly.

Myth 7: Place a Pebble Tray Under Your Pot

Contrary to popular belief, pebble trays do not significantly increase humidity for houseplants. The amount of humidity they generate is minimal and does not reach the plant. Consider using a humidifier for additional humidity.

Myth 8: Certain Foods Can Make Shinier, Healthier Leaves

Applying foods like eggs or mayonnaise to leaves to enhance shine is detrimental to plant health. These substances can clog leaf pores, hindering light absorption and potentially leading to plant damage.

Myth 9: You Either Have a Green Thumb or You Don’t

Plant care is a learnable skill. Start small, experiment with different plants, and learn from your experiences. Even if some plants don’t survive, you’ll gain valuable knowledge and become a more confident plant parent.

Additional Tips for Thriving Houseplants:

  • Do your research to understand the specific needs of your plants.
  • Provide adequate light, water, and nutrients.
  • Use well-draining soil and containers with drainage holes.
  • Monitor plants regularly for signs of pests or diseases.
  • Don’t be afraid to ask for help from experienced plant enthusiasts or consult online resources.

Saving the Corpse Flower: Collaboration is Key to Preserving Genetic Diversity

by Rosa
written by Rosa

Saving the Corpse Flower: A Collaborative Effort

Genetic Diversity: The Key to Survival

The corpse flower, Amorphophallus titanium, is a rare and unusual plant that captivates the world with its unique appearance and infrequent blooming cycle. However, its genetic diversity is shallow, posing a significant threat to its existence. Inbreeding, which occurs when closely related individuals mate, can lead to unviable seeds and a decline in the plant’s overall health.

Studbook-Inspired Conservation

To address this issue, horticulturalists have adopted a method inspired by “studbooks,” which are genetic maps traditionally used in animal breeding and zoos to prevent inbreeding. A studbook for corpse flowers tracks the genetic makeup of individual plants, allowing researchers to identify the best matches for cross-pollination.

The Role of Botanic Gardens

Botanic gardens play a crucial role in the conservation of endangered plant species, including the corpse flower. In 2019, the Chicago Botanic Garden launched the “Tools and Resources for Endangered and Exceptional Plant Species” (TREES) project to create a studbook-like database for six rare plant species, including the corpse flower.

Recalcitrant Seeds: A Unique Challenge

Many of the plants in the TREES project, including the corpse flower, have recalcitrant seeds. These seeds cannot withstand the freezing or drying methods used in traditional seed banks and require specific conditions to survive. In the wild, animals often consume and disperse recalcitrant seeds.

Asexual vs. Sexual Reproduction

Corpse flowers can reproduce both asexually and sexually. Asexual reproduction produces multiple genetically identical plants, while sexual reproduction involves the fusion of pollen and eggs to create genetically diverse offspring.

Artificial Pollination and Cross-Pollination

Since corpse flowers only bloom for a short period of time, botanists must artificially pollinate them to produce more offspring and genetic variation. They also collect pollen from blooming plants to share with other botanical gardens for cross-pollination.

The Longwood Botanical Gardens’ Success Story

In 2020, a corpse flower named “Sprout” at the Longwood Botanical Gardens in Pennsylvania bloomed for the second time. Pollen from the Chicago Botanic Garden was used to artificially pollinate Sprout, resulting in the production of viable seeds.

Collaboration is Key

Collaboration between botanic gardens is essential for the conservation of critically endangered plant species. Researchers at the Chicago Botanic Garden emphasize the importance of working together to save these species, as individual gardens cannot accomplish this task on their own.

Long-Term Goals

The TREES project aims not only to save rare species like the corpse flower but also to develop principles that can be applied to the conservation of other endangered plant species in the future.

Corms, Bulbs, Tubers, and Rhizomes: A Comprehensive Guide to Underground Plant Stems

by Rosa
written by Rosa

Corms, Bulbs, Tubers, and Rhizomes: An in-depth exploration

What are corms, bulbs, tubers, and rhizomes?

Corms, bulbs, tubers, and rhizomes are all underground plant stems that store nutrients for the plant to use later. They are all swollen and modified, but they have different structures and growth patterns.

  • Corms are solid, rounded or oval underground stems that store nutrients. They have a papery outer layer and a central bud that will eventually become a flower. Corms do not have layers like bulbs. Examples of plants that grow from corms include crocuses, gladiolus, and cyclamen.

  • Bulbs are underground stems that are made up of layers of fleshy leaves. The bottom of the bulb is a compacted stem, with roots growing from it. Layers of nutrient-filled leaves sit at the bottom of the bulb and surround a bud that eventually becomes a flower. Examples of plants that grow from bulbs include daffodils, hyacinths, and tulips.

  • Tubers are swollen stems or roots that store nutrients. They have buds, or “eyes,” that can sprout into new plants. Tubers can be cut into pieces, and each piece can be planted to grow a new plant. Examples of plants that grow from tubers include potatoes, dahlias, and begonias.

  • Rhizomes are modified, swollen stem-like structures that grow horizontally. They form roots from the bottom and send shoots upwards. Buds form at different parts along the rhizome, not just the tip. Examples of plants that grow from rhizomes include Japanese knotweed, lily-of-the-valley, and canna lily.

How to identify corms, bulbs, tubers, and rhizomes

Corms, bulbs, tubers, and rhizomes can be identified by their shape, structure, and growth pattern.

  • Corms are solid and rounded or oval in shape. They have a papery outer layer and a central bud.
  • Bulbs are made up of layers of fleshy leaves. They have a papery outer layer and a basal plate at the bottom.
  • Tubers are swollen stems or roots. They have buds, or “eyes,” that can sprout into new plants.
  • Rhizomes are modified, swollen stem-like structures that grow horizontally. They form roots from the bottom and send shoots upwards.

The role of corms, bulbs, tubers, and rhizomes in the ecosystem

Corms, bulbs, tubers, and rhizomes play an important role in the ecosystem. They provide food and shelter for wildlife, and they help to aerate the soil and improve drainage. Corms, bulbs, tubers, and rhizomes are also a valuable source of food for humans and animals.

The benefits of growing corms, bulbs, tubers, and rhizomes in the garden

Corms, bulbs, tubers, and rhizomes are a great addition to any garden. They are relatively easy to grow, and they provide a long season of blooms. Corms, bulbs, tubers, and rhizomes can also be used to create a variety of garden designs, from formal to informal.

by Peter
written by Peter

How to Grow and Care for Rosy Maidenhair Ferns

Overview

Rosy maidenhair ferns (Adiantum hispidulum) are elegant and textural plants that thrive in shady gardens and as houseplants. With their unique rose-colored fronds that mature to a dark green, they add a touch of whimsy to any setting.

Growing Conditions

Light: Rosy maidenhair ferns prefer dappled light, as too much direct sun can scorch their leaves. In northern regions, they can tolerate less intense morning sun. Indoors, place them in a spot with bright but indirect light.

Soil: Well-drained soil is essential for rosy maidenhair ferns. They cannot tolerate standing water, which can lead to root rot. Slightly acidic soil enriched with organic matter is ideal.

Water: Regular, deep watering is crucial, especially when first planting a new fern. Once established, continue to water frequently enough to ensure even moisture. Avoid overwatering, as too much moisture can lead to root rot.

Temperature and Humidity: These tropical ferns love humidity. They can be evergreen indoors with adequate humidity or in tropical or semi-tropical climates. Ideal daytime temperatures indoors are around 70 to 75 degrees Fahrenheit, and humidity levels between 40 and 50 percent.

Fertilizer: A balanced, diluted liquid fertilizer can be applied monthly during the growing season to encourage lush frond growth. Avoid overfeeding, as too much fertilizer can burn the foliage.

Care

Pruning: Rosy maidenhair ferns require minimal pruning. Simply remove any broken, unhealthy, or dead fronds in the spring.

Propagation:

Division: Divide clump-forming ferns in the spring before new fronds unfurl. Dig around the plant and carefully separate the rootball into two or three divisions.

Spores: Rosy maidenhair ferns can also be grown from spores. Collect spores when they are ripe in the fall and sow them on moist, sterile fern potting medium. Keep the container warm and humid until germination occurs.

Common Problems

Browning Fronds: Dry, curly fronds indicate underwatering or insufficient humidity. Increase watering frequency or invest in a humidifier.

Drooping Fronds: Wilted, drooping fronds can be a sign of underwatering or low humidity. Ensure the fern is receiving adequate moisture and humidity. Avoid overwatering, as soggy soil can lead to root rot.

Yellowing Leaves: Yellowing leaves can indicate root rot due to overwatering or poorly draining soil. Repot the fern in fresh, well-draining soil and adjust watering practices.

FAQs

How often should I water a rosy maidenhair fern?

Water when the soil surface feels dry to the touch. This could be as frequently as every few days to a week in the growing season.
