- Pruning
Pruning Platanus × hispanica is important for maintaining its shape, removing dead or damaged branches, and promoting healthy new growth. It is best to prune in late winter or early spring, before new growth begins. It is important to remove any dead, diseased, or damaged branches as soon as they are noticed. This will prevent the spread of disease and pests. When pruning, make sure to cut back to a healthy lateral branch or bud. Avoid leaving stubs as they can lead to decay and attract pests. Also, it is important to remove any crossing branches as they can rub against each other and cause damage.
- Soil

- Life cycle
The London plane tree begins its life as a seed, which germinates when it comes into contact with water and the appropriate temperature. Germination typically takes between 7-14 days.
Once germinated, the seedling begins to develop roots and leaves. At this stage, the tree is highly dependent on water and light to survive.
As the tree grows, it enters the sapling stage. At this stage, the tree is starting to develop a more distinct trunk and branches. It is still dependent on water and light, but is becoming more self-sufficient.
Once the tree reaches maturity, it is fully grown and self-sufficient. At this stage, the tree is able to reproduce, producing flowers and seeds.
Eventually, the tree will begin to decline and enter the senescence stage. The tree may die back, lose its leaves, and no longer produce flowers or seeds. - Propogation

Spring
By SEEDS:
The easiest and most common method of propagating the London plane tree is through seed. The seeds are collected in fall, when the tree's fruit or samara are ripe. The seeds can be sown immediately or stored in a cool, dry place until spring. Germination typically takes 7-14 days.
By ROOT CUTTINGS:
Another way to propagate the London plane tree is through root cuttings. This method involves taking a cutting of a mature tree's roots and planting them in soil. This method is typically done in late fall or early winter.
By GRAFTING:
Grafting is a method of propagating the London plane tree by attaching a cutting from one tree to the rootstock of another. This method is typically done in late winter or early spring.
By AIR LAYERING:
Air layering is a method of propagating the London plane tree by rooting a stem while it is still attached to the parent tree. This method is typically done in late spring or early summer.
