at least in my area the black is the excrement of pests on the plants. it can be mold or fungus, too. there are many many things it could be depending on the plant type and region. if you are looking for a specific answer, take a sample of the leaves in to a knowledgeable nursery (most likely a non-corporate nursery)
Deciduous trees and shrubs shed their leaves in Autumn and grow new leaves in Spring.
Pine trees don't have "leaves", they have needles. These needles turn brown and fall off from time to time. New needles grow in to replace the old ones that died.
No, most deciduous trees lose their leaves in the spring season. This paves the way for new leaves to come in.
Trees that shed their leaves every year are called deciduous trees.
Deciduous trees loose their leaves in the fall and grow new ones in the spring.
To rejubinate growth older leaves fall off and new leaves come in.
when Autumn stops and Winter start the trees get cold and have to grow more leaves
i think it has to do with sunlite
penis. No. Deciduous trees lose their leaves in the autumn and then grow new ones in spring.
The deciduous trees before entering into adverse environmental conditions lose their leaves as an adaptation. New leaves come in to have more effecient metabolic activity.
Apple trees are deciduous trees. This means that they loose their leaves in the fall and they reshoot in the spring and grow new leaves.
in the fall the air is getting colder. so the clorophyll in the leaves, which is what makes them green, goes back in the tree and gets ready for winter. since the leaves dont have any clorophyll they turn the color that it would have been before the clorophyll was deposited in the first place. then they fall off. In the spring, the clorophyll that was frozen in the trees turn into new leaves.
yes, they only eat the trees bamboo leaves, but new ones grow again
Deciduous trees lose their leaves in the autumn. Mostly these are broadleaf trees, but some conifers are also deciduous. In New Zealand, there are only a couple of species that mostly lose their leaves in the winter. The generalization that broadleaf trees lose their leaves in the winter is a northern hemisphere misbelief.
no INDEED NOT MWAH HAHAHAHAHAH
floewer blooming, new leaves to the trees and a Bengali new year
Deciduous trees generally shed their leaves in Autumn and grow new ones in Spring, but a few may hold leaves until spring. Evergreens shed leaves throughout the year, some in the Spring.
Evergreen trees kept their leaves all winter. The leaves are often called needles. There are also trees like some varieties of magnolias that keep their leaves until spring when they grow new ones.
Australian native trees do not change colours in the Autumn. However, there are many non-native trees in Australia, and these do indeed provide a colourful sight during autumn. Cities such as Orange in New South Wales and Toowoomba in Queensland have many such trees.
This question is almost impossible to answer. New leaves grow every year and old ones die.
Perhaps the only good that tornadoes do is that they often destroy older trees. This leaves room for new trees to grow.
