How to Get the Soil Ready Cauliflower Planting

You may not be aware, but one of the reasons why gardeners fail to successfully grow cauliflowers is because of poor soil preparation.

Cauliflowers are heavy feeders that grow continuously and rapidly.  Thus, it is necessary for the soil to have enough nutrients so it can support this growth.

Aside from being voracious feeders, cauliflower favors a sweet soil (with an acidity between 5.5 to 6.5pH) that drains well and that they also have a weak root system.

Planting cauliflowers can happen as early as six weeks before the danger of frost if over – even when the temperature is between 65 to 75 degrees.  However, soil preparation must be done months before.

How should the soil be prepared?

A few months before actually planting, cut all visible grass in the area.  Also cut off branches and twigs from nearby trees that may shade your cauliflowers.  Using a grub hoe, shovel or fork, loosen the soil until a good tilt is obtained.

Do not fumigate the soil as soil-borne diseases like clubroot flourish in soils where they don’t have to compete with other micro-organisms.

Make plots that have a width of one meter and a length of 5 to 20 meters.  It should be six to eight inches high.  The plots should be positioned in an east-west direction so your crops will receive sunlight yet not expose them to the north winds.  Use a rake to level your plots.

Ideally, it is best to use only biologically active fertilizers such as mushroom compost to build soil structure.  But you may also use basal fertilizer mixture, mixed in with aged compost, and urea.

Even if the soil you have is rich and fertile, it will still do good to apply commercial fertilizer to the soil like 5-10-10.   Such fertilizer has boron and magnesium which cauliflowers need to grow properly.  Do this a few weeks before the plants will be set.

For sufficient supply of nitrogen, add chicken manure to the soil three weeks after the cauliflowers had been set out.  Make sure the soil is evenly moist.
