Bindweed To prevent germination of weed seedlings, apply an opaque mulching film or layer of bulky organic mulch, such as woodchips, to the soil at a depth of at least 8cm (3in). Some seeds with panicles (or wings), such as the dandelion and sycamore, float in the wind for wide distribution. The faded dandelion transforms into a ball of white fluff, and when ripe and ready, they’re ripped from the plant by a gust of wind, landing up to 10 metres from the plant.

Himalayan balsam is an invasive annual weed that can grow up to 2-3 meters tall. It has reddish stems, long narrow leaves, and produces pink or purple helmet-shaped flowers. It is commonly found near water bodies and damp areas. Biological control with fungal pathogens of the genus Septoria and of the genus Phoma has been investigated. The species demonstrate sufficient pathogenicity and host specificity to be regarded as promising biocontrol agents. The host-specific fungus, Erysiphe convolvuli, has also been evaluated as a potential biocontrol agent of field bindweed. An inoculum of the fungus Phomopsis convolvulus has caused severe damage to field bindweed plants at all growth stages. The extent of the damage varied with plant age. Seedlings at early leaf stages were more sensitive than established plants. Timing and weather conditions are critical if biological control is to be effective.On grassy banks in summer, the big, shiny, pink or white flowers above delicate foliage look like a garden escape Epidyolex can be prescribed by a specialist for patients with Lennox-Gastaut syndrome and Dravet syndrome (both rare forms of epilepsy).
