No, some trees will die if planted deeper than the roots. You can repot it and get away with the dirt being 1 inch higher than the roots.
its roots aren't picking up enough water and nutrients after the move.
fibrous
For deeper sources, the taproot would be a better choice because it digs deeper into the ground for water and minerals.
A plant may send the roots deeper down because of the lack of water. Because normally when the plant is in need of food it is watered but these are trees so they have to turn/grow deep underground for there food ! Like the giant redwoods in Calafornia which are over 3200 years!
Lateral roots is Endogenous. Adventitious roots have lateral roots.
its roots aren't picking up enough water and nutrients after the move.
Plastic generally helps hold in moisture. Depends what kind of plant you are repotting. Unless it's in the miniature category you can use from a 4 inch size pot. Keep in mind that if the plant you're repotting is a flowering type it's best that you don't plant it in a huge pot because it might not flower. Some varieties like their roots compacted.
Repotting is essential for plant growth. If a plant is left for too long in it's pot it may become root-bound and stop growing. Root-bound means, in a potted plant, that the plant has over-grown it's pot. The space in the pot has become filled with the roots of the plant and there is little or no dirt left. If there is no dirt left there is no substance for nutrients and the plant will stop growing. Depending on the plant, typically repotting consists of trimming the excess roots at the root ball, leaving 2-3 inches of roots and repootting the newly trimmed plant. It may be a good idea to use a bigger pot, again depending on the plant.
it has deeper roots
In search of moisture in dry weather or deeper rooting for anchorage.
Because they have deeper and older roots in history.
fibrous
Because it's roots weren't deep enough to reach the water in the soil. Use native grasses with deeper roots, like fine fescues, instead of Kentucky blue. Fescue roots go down 6 inches while Kentucky blue struggles to get 2 inch roots. The deeper the roots, the less you will have to water too.
Taproots are the anchor roots of plants . The taller the plant the deeper the tap root.
No cacti actually have very shallow roots because they are adapted to absorb rain water fast
If it is Araucaria excelsa the Norfolk Island pine, it will have been stunted by the roots being potbound. When planting tease some of the root ends out of the rootball or they tend to stay restricted. It will possibly never reach full glory but should make a nice tree.
Cacti have very strong roots that go deepinto the Earth searching for water. Since they go so far, they must be very strong. The stronger the roots, the deeper they search for water. Roots secure plants to the ground, but some can't.
