Bulbil Watsonia Watsonia meriana Declared Noxious Weed Environmental Weed Factsheet Origin: South Africa Size: 0.5-2m H, 0.5-1.5m W Best removal time: September Flowers: September to DecemFruits: October to December What it does… Invades gardens, bushland and roadside areas where slashing and maintenance help to spread the bulbils. Tolerates full sun, moist areas, shady and windy conditions. Takes over and displaces indigenous grasses and groundcovers. What it looks like… How to remove it... Remove by Hand: Easiest for small clumps. Larger areas can be forked when the soil is quite moist. Follow up is necessary to remove all corms. Most effective just before flowering. Dig out: Dig out patches of Watsonia. You The leaves are rigid, straight and sword-shaped, with a prominent mid-vein, up to 80cm long. The flower spikes can stand up to 2m. They bear two rows of dull orange, curved tubular flowers. The lower part of the flower spike carries clusters of bulbils. will need to ensure all corms are removed and take care not to drop bulbils as the plant is disturbed. If the soil is moist this is best done using a garden fork. It is important to avoid dumping the soil elsewhere. How it spreads… Spray with herbicide: Watsonia can be Watsonia reproduces mainly by producing new corms (a corm is an underground swollen stem that forms the base of the plant) and by dropping the bulbils (inset, left) from the flower spike. Each bulbil then grows into a new plant. Plants die back to the corm and reshoot each winter. Corms and bulbils spread: • through water, • contaminated soil and • dumped garden waste. • Sale at markets and fetes. Buyer beware! sprayed or leaves swiped with a glyphosatebased product. The most effective time is just before full flowering which occurs in spring. Declared Noxious Weeds... Have the potential to spread widely and cause serious economic loss to agriculture, or have some detrimental effect upon people, animals, the environment or the local community. Indigenous alternatives to plant… Many lily and iris alternatives exist that are indigenous to the Yarra Ranges region and would make great substitutes for the Bulbil Watsonia. Some alternatives include: Spiny Mat Rush, Lomandra longifolia Butterfly Flag, Diplarrena moraea How to dispose of weeds: Using Chemicals: By disposing of environmental weeds correctly you can prevent re-infestation on your property and elsewhere. Non chemical treatments is often the most effective and safe option especially on smaller scale infestations. • Where chemical use is undertaken: • • • • • Landfill (Weed Wipeout Tip vouchers available for some species). Green waste bin ensures that weeds are not able to spread. Woody weed stems can be bundled for green collection twice per annum. Composting (excluding seed heads or species with vegetative reproduction, e.g. Wandering Trad). Burning in accordance with Council and the Country Fire Authority (CFA) prescribed burning periods and regulations. Recovery and transfer stations available for weed tipping are Healesville, Wesburn, Coldstream, Lysterfield and Montrose. • • • • • • • Bare ground attracts WEEDS!!! • Always follow the manufacture’s guidelines when using chemicals. Wear protective clothing and eyewear On purchasing your herbicide, always ask for a Materials Safety Data Sheet (MSDS) or refer to the manufacturer’s website for specific safety guidelines and information. Some herbicides will kill other plants and not just the target species. Near waterways herbicides can be very poisonous to aquatic life. Use chemicals sparingly and be sure that you are using the right chemical and application technique. Ensure the weather conditions are suitable (e.g. minimal wind and no rain expected) Apply herbicides at the correct time during the plant’s growth cycle so you get the best results.. For effective long term weed control we recommend: • Habitat Restoration - Encourages indigenous and native plant to regenerate - Revegetation - replanting indigenous vegetation • Productive land use. • Replace with non invasive garden species.
