Leaf spots reduce the surface area available on leaves for photosynthesis and so can result in smaller growth and yield of plants. Weakened plants may produce lesser fruit. Virus caused leaf spots reduces chlorophyll in the leaves, resulting in less photosynthetic activity.
Dry leaves, along with dry grass, dead plants, wood chips, shredded paper, and sawdust are examples of carbon to place in the compost. Oxygen or green material includes grass clippings, produce ...

Ancient Latin gutta means "a drop of fluid", whence modern botany formed the word guttation to designate that a plant exudes drops of fluid onto the outer surface of the plant, when the ...
Forsythia are deciduous shrubs typically growing to a height of 1–3 m (3 ft 3 in – 9 ft 10 in) and, rarely, up to 6 m (20 ft) with rough grey-brown bark. The leaves are borne oppositely and are usually simple, though sometimes trifoliate with a basal pair of small leaflets; they range between 2 and 10 cm (0.79 and 3.94 in) in length and, rarely, up to 15 cm (5.9 in), with a margin that is ...
Clean up your lawn and turn fallen leaves into fertilizer with a leaf mulcher. Consider these expert-recommended models from Worx, Black and Decker, and more. Repurpose Fallen Leaves with the 8 ...
The symptoms of Drechslera leaf spot are mostly small, dark-brown, or purplish spots on the leaves. [1] The spots eventually expand and become lighter-brown or ashy in the middle (usually having dark margins around the center). Once the spots run together, girdling of the entire leaf blade occurs. Warm weather induces crown rot and eventual ...
