The magnolia tree
There is a myth that the fig tree is cursed. It is untrue, in fact it is reason the fig is considered scientifically a bud and not a fruit. This is reason most figs bloom along with the leaves.
like the leaves prob turned into the fruit!!! ;)
It would be early in Spring, before the tree buds out, April or May. Any time the tree is dormant, the leaves are off, you can trim it easily with little harm to the tree. If you must do it in summer, wait until after the tree has flowered.
The Umbrella Thorn Acacia tree, found in Africa, has leaves that can grow up to the size of footballs. These large leaves help provide shade for animals in the savanna.
A tree has to bloom before it can bear fruit.
Figs bear in their first year after planting, and usually produce two crops, in the Summer and in the Fall. Also Figtrees bear Figs before the tree has leaves, if you see a fig tree with leaves out of the season of Figs you know there should be fruit unless the tree is a pervited tree (trying to be something when its not) see Mark 11:13-14
Manypeople always associated sineguelas with the spookiness of its tree before it bore fruit. The sineguelas tree sheds off all its leaves before it flowers, and the fruits appear just in time for the summer. Wait for the fruits to turn red because that's when they're sweet and juicy. Nutritionists tell us that the sineguelas is loaded with Vitamin C.
The pineapple
Yes, the rain tree, also known as the Samanea saman tree, does produce fruit. Its fruit is a pod that contains seeds and is often consumed by animals.
If you mean why does " your fruit tree have no fruit " than it's either the tree requires another fruit tree to pollinate it or trees take time to mature before bearing fruits.
Taking your question literally, these leaves are edible, the Little Leaf Linden or Lime Tree, the Fragrant Spring Tree from Japan and the Mulberry. There is also a Chinese tree called the Goji No. The fruit of a tree is the seed containing capsule. The leafs are the foliage edible or not.
