As autumn takes hold, gardeners are advised to collect fallen leaves either for composting or storage in perforated bags to allow drainage. This season offers favorable conditions for planting, with still-warm soil aiding root establishment. Garden centers present opportunities for acquiring new plants, including autumn bulbs, while November remains the ideal time to plant tulip bulbs.
Lawn care adjustments include reducing mowing frequency and considering the installation of new turf. Gardeners are also encouraged to bring houseplants back indoors after their summer outdoor period, inspecting for pests such as aphids on new growth and removing them manually. Vegetable beds should be cleared of old debris to prepare for planting spring cabbages and winter lettuces. Pumpkins can be placed on bricks to improve dryness and assist ripening ahead of Halloween. Greenhouse maintenance, including thorough cleaning and disinfection, is recommended to prevent the establishment of pests and fungi during the colder months.
In response to a reader's inquiry about a furry growth on a climbing rose bush, experts identified it as Robin’s pin cushion—a gall produced by a wasp laying eggs in the rose, which causes abnormal growth as the larvae develop inside. These galls are harmless and should be left undisturbed as part of the ecosystem.
The transition from summer to autumn has been visually marked by swirling bronze leaves, a consequence partly tied to this year’s intense heat and drought conditions, which have caused many deciduous trees to shed leaves early. Alongside this seasonal change, birdwatchers have observed strong migratory movements of species such as whinchats, wheatears, redstarts, and both spotted and pied flycatchers. These birds appear to have experienced successful breeding seasons, with their young actively enhancing birdwatching experiences nationwide.
Looking further into the season, attention turns to several species of leaf warblers belonging to the genus Phylloscopus, known for their bright green plumage and insectivorous habits. Typically wintering in Southeast Asia, these warblers—including Pallas’s, Arctic, greenish, yellow-browed, and Hume’s—are increasingly noted on western shores from late summer through November. While populations of Pallas’s leaf warbler have declined slightly from an average of 90 to 58 annual sightings since 2000, observations of Arctic and greenish warblers have risen significantly. The number of Arctic warbler sightings has tripled, averaging 18 each year, while greenish warblers have doubled to around 30.
Experts debate whether these shifts reflect changes in population levels or alterations in migratory routes, potentially influenced by climate change. Enhanced identification skills among birdwatchers have also contributed to detecting these elusive species more frequently, underscoring both environmental concerns and growing public interest in avian migration patterns.
