Iron is best absorbed in acidic soils. If there is also significantly phosphorus, like lime or a different fertilizer with substantial P amounts, it can inhibit plants from absorbing the iron, even if the iron amounts are satisfactory.

  • Liquid – Liquid types of iron supplements are obtainable to plants quickly and really don’t need to have time to break down. These formulas are normally foliar, sprayed across the lawn, and absorbed by the grass Liquid iron will assistance the grass remain as green as it can be for a couple of weeks and can then be reapplied.
  • Granular – Sound types of iron supplements may perhaps get a couple of weeks to be utilized by the grass, considering that these have to be dissolved gradually and will be absorbed a minor bit at a time. This additional systemic answer adds iron and other nutrients to the soil for longer-phrase coverage.

Granular solutions like Dr. Iron and Ironite have iron at a ratio of 20% to 22%, whereas liquid solutions like Southern Ag and LawnStar are in concentrations of 5% to 6%.

As well far on both side of acidic or alkaline is not very good for the overall health of the grass.

Can You Apply Ironite And Fertilizer At The Identical Time?
