What is Over-Fertilization?

Excessive fertilizing tends to be more of a problem than under-fertilizing. Information technology is very like shooting fish in a barrel to overdo fertilizing and there are several factors that, in combination with excess fertilization, tin cause negative effects.

Fertilizers accept high amounts of unlike salts that can pull moisture abroad from the roots in a procedure chosen reverse osmosis. If the salt content in the soil is higher than what the plant contains, then opposite osmosis volition occur.

Reversing the effects of over-fertilization is possible, but time is needed before the plant returns total wellness. Container-grown plants can exist affected more than apace compared to those grown in the ground, merely excessive fertilizer damage can be corrected more easily.

A process known as "leaching" can right soils loftier in fertilizers, which we'll talk about in further particular below.

Salts in fertilizers can damage plants.

Symptoms of Over-Fertilization

At that place are several symptoms of excessive fertilizer application, including:

Stunted growth
excessive growth of leaf with few blossoms
discoloring on the edges of leaves

The about astringent damage occurs undercover in the roots. Excess salt in fertilizers can "burn" the roots and limit moisture uptake. The combination of burns and limited water uptake volition quickly pb to a decrease in plant wellness. The afflicted roots will also get weakened against affliction.

Running the garden hose will leach excess fertilizer away from roots.

Curing Over-Fertilization

Leaching

Backlog nutrients and salt need to exist removed by a process called "leaching." Leaching is the movement of nutrients down through the soil via watering. Leaching washes the extra nutrients out of the soil or below the root zone, assuasive the plant to brainstorm the recovery process.

Plants in Containers

Cheque the surface of the soil around the plant for a white crust. Soluble salts from the crust can brand their style to the roots and cause more impairment during leaching.

The crust needs to be advisedly removed from the rest of the soil. Remove no more than than one-quarter inch of soil from the surface. Sometimes the crust is hard enough that it can be picked out in big chunks. Be careful not to remove too much soil forth with the crust. Removing too much can stress the plant even more. Leaching can begin once the crust is removed.

For container-grown plants:

use room temperature distilled h2o and fill the container to the top border. Distilled room temperature water is the all-time h2o to apply considering it contains no dissolved minerals and will not add together farther stress. Filtered h2o can be used if distilled water cannot be obtained.
Allow all the water to drain from the constitute. Large containers will have quite a while to drain so accept patience.
Repeat this nigh 4 times.

Excess fertilizers volition be washed from the soil and bleed through the lesser of the container.

Enquiry the soonhoped-for fertilized plants before application equally well. Different plants crave different formulations and may be susceptible to certain formulations. Succulents cannot handle rich fertilizers while fast-growing plants can. Information technology all comes down to the institute and adequate enquiry to prevent fertilizer damage.
