It might be too cold. More likely you are over watering it. To prepare for xerophytic conditions the cactus leaves drop off the plent.
When the true leaves of the seed appears.
All trees are perennial. Deciduous trees drop their leaves in the Autumn. Evergreens do not drop them at any specific time of year.
trees lose their leaves because the sun gives them chlorophyll. without chlorophyll, the leaves die and drop off.
Known as the water cycle, basically, water is evaporated off the oceans and form clouds. The clouds drop rain on the land, and the rain water flows downwards and into rivers, and returns to the ocean. The water cycle then continues.
No they don't. What kind of trees are coniferous? It means, cone bearing. So, the most familiar kind of cone on a tree is the pine cone. What kind of leaves do pine trees have? They have needles, very narrow leaves that do not drop off in the fall, but stay on all year. Some conifers, such as the Larch, drop their leaves in the Autumn, but they do not have large broad leaves.
Seed leaves, also known as cotyledons, typically dry up and drop off as the plant transitions to using its true leaves for photosynthesis. This process is natural and allows the plant to redirect its energy towards producing new growth. It's a sign of the plant's healthy development.
Gravity, wind, birds, squirrels
I'd set it out in the rain. A nice gentle rain will wash all the dust off the leaves and perk it up.
All leaves will eventually drop off trees... there is no real way to prevent that from happening. Leaves die and gravity does the rest. However, trees in the tropical rainforests are not deciduous-- meaning they do not drop all of their leaves in autumn. Because it is summer year-round in the tropical rainforests, there is no autumn and the leaves do not change colors or all fall at once.
Yes, peach trees are deciduous, meaning they lose their leaves in winter. This is a natural process that helps the tree conserve energy during the colder months. The leaves will typically turn yellow or red before falling off.
Leaves disappear in the fall because the days become shorter and temperatures drop, causing trees to go into dormancy. During this process, trees stop producing chlorophyll, the compound responsible for the green color of leaves, which leads to the leaves changing colors and eventually falling off. This helps trees conserve energy and prepare for the cold winter months.
