However, white grubs (reaching 40–45 mm long when full grown) live in the soil and feed on plant roots, especially those of grasses and cereals, and are occasional pests in pastures, nurseries, gardens, and golf courses. An obvious indication of infestation is the presence of birds, such as crows, peeling back the grass to get to the grubs.
It is responsible for a disease (commonly called milky spore) of the white grubs of Japanese beetles. The adult Japanese beetles pupate in July (in the Northeast United States) and feed on flowers and leaves of shrubs and garden plants. During this adult stage, the beetles also mate and the females lay eggs in the soil in late July to early August.
The cane beetle grub feeds on the roots of the sugarcane during all three stages of its life. The crucial stage occurs during February to May, when it aggressively feeds on the sugarcane's roots, causing the most damage to the plant. [1] Once it is fully fed, after 3–4 months, the grub burrows down to turn into a pupa.

"Watering at this time can lead to water freezing around the roots or on leaves, which damages the plant," says Porwol. Additionally, many plants go dormant during winter and require less water ...
"Warm season turf grasses generally go dormant during the winter months," says Harlow. "If they are in Zones 9B -11, they may not go dormant at all." Cool-season grass may continue to grow in ...
Switchgrass is a hardy, deep-rooted, perennial rhizomatous grass that begins growth in late spring. It can grow up to 2.7 m (8 ft 10 in) high, but is typically shorter than big bluestem grass or indiangrass. The leaves are 30–90 cm (12–35 in) long, with a prominent midrib.
The deep and hollow roots of the plant branch out from lower nodes. Leaves: Since the grass has short internodes, all the leaves grow out from the plant's base. Each clump's diameter can increase up to 4 ft (1.2 m). [8] The stems and leaves have a purplish color and are glabrous.
