When the water table is close to the surface or when soil is compacted, most trees develop fibrous roots. Hickory, conifer, oak, pine, pecan and walnut trees do have taproots, but most fruit and shade trees do not. Many desert plants have long taproots to mine water in very dry conditions.

The root system is typically shallow and spreading, sometimes covering 50 ft (15 m) of ground, but in permeable soil some of the roots may descend to 20 ft (6 m)….Ficus carica.

An alternative to poisoning is to dig a trench between tree and house and put an impervious barrier between the two. Builders plastic doubled over several times should be O.K. Even an air barrier will work. Also, roots generally only follow moisture so if they’re heading for your house there must be some water there.

Bananas (Musa spp.) Both dwarf and standard-sized bananas share a root system uncommon among fruit-bearing plants: They are fed and reborn yearly from a fibrous root system that supports a reproductive rhizome.

Most trees begin life with a taproot, but after one to a few years change to a wide-spreading fibrous root system with mainly horizontal surface roots and only a few vertical, deep anchoring roots.

An example of a tap root system is a carrot. Grasses such as wheat, rice, and corn are examples of fibrous root systems.

Grasses and other monocotyledons (angiosperms with a single seed leaf) have a fibrous root system, characterized by a mass of roots of about equal diameter. This network of roots does not arise as branches of the primary root but consists of many branching roots that emerge from the base of the stem.

Fibrous root systems are characteristic of monocots, which include the cereal crops corn, rice, wheat, barley, sorghum, millet, oats, rye, teff, and so forth.

Fibrous Root System: Types, Modifications and Examples

• Fleshy Fibrous Roots.
• Stilt Roots.
• Reproductive Roots.

A fibrous root system is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem. The fibrous root systems look like a mat made out of roots when the tree has reached full maturity.

In a fibrous root system, the roots grow downwards into the soil, and also branch off sideways throughout the soil. This forms a mass of fine roots, with no distinct tap root, because the embryonic root dies back while the plant is still young and growing.

Both fibrous root system can be most advantageous root system for plants depending upon the following usage:

• Water and Nutrient absorption – Fibrous roots have thicker branching system as well as have more numerous roots.
• Plant Anchoring – Taproots anchor plants better since they anchor deeply.

The fibrous roots are thin, with root hairs, and their function is mainly absorption of plant nutrients and water from soil. When the plant grows further, several fleshy roots of indefinite growth are produced from the lower nodes of the mother ginger rhizome and primary fingers.

The fibrous root system is also called an adventitious root system due to the presence of adventitious roots.

How Deep Does a Tomato Plant’s Root System Go? As dicots, or plants that have two embryonic leaves (called cotyledons), tomatoes have a taproot system. This is in contrast to the fibrous root system of monocots, plants that have just one embryonic leaf.

The root system of a tomato plant might extend to as much as 2 feet deep, but the main portion of the root system lies in the first 12 inches under the soil. Because the roots lie close to the surface, it is important to dig carefully around tomato plants so you don’t damage the roots.
