When sowing the spinach seeds, use general garden fertilizers in the ratio 10-10-10 at a 2-3 pounds rate per 100 sq feet. Mix the soil with fertilizers about 3 inches and keep adding every 30 days. The plant prefers a cool temperature for the seeds to germinate. The endurance of the spinach plant to withstand cold temperature ranges from 7-24 degrees C but can withstand a low as -9 degrees C.

Peat soils often get used, and they generate a healthy yield. The use of alfalfa meal in the ground increases the nitrogen content, one of the essential nutrients for its growth. One can use Blood meal to spoil instead of Alfalfa, but it will attract meat-eating animals to the cultivation area. Every 30 days, add a healthy proportion of organic fertilizers and cover crops, compost, and manure making the soil rich in nutrients. The decomposing organic matters of the earth will add a healthy share of microbes into the earth, which will help in breaking organic matters of the soil and make them suitable for the roots to absorb.

When to Plant Spinach:

The best time for Growing Spinach belongs to the weather season. The plantation thrives when it receives frost, and a perfect soil temperature makes the yield suitable. To begin with, before sowing the Spinach seeds, one needs to prepare the soil using organic nitrogen-rich fertilizers and compost. The best thing one can give the plant the required six weeks of cool weather from seeding to the day of harvest. The soil temperature for the Spinach seed to germinate ranges from 60-70 degrees F; in the early spring, cultivators can do successive plantings for a year-round supply of Spinach.

People living in countries with mild winter can start Planting spinach seeds in the fall when the soil temperature drops to the optimal limit for growth.

How to grow Spinach:

Picking the perfect spot for sowing spinach seeds plays a vital role in its future yield. Pick a place where it receives partial sunlight with a well-draining soil structure. Now, begin preparing the soil using old manure that adds nitrogen to it. One can do crop rotation along with Spinach using heavy feeder crops to prevent soil exploitation. Theoretically, one can begin sowing in indoor areas and then transfer the spinach seedlings to the garden area. In practicality, the plant cannot withstand the transfer shock and eventually dies. So, begin outdoors, sow the spinach seeds  ½ -1 inch deep soil, and provide a light soil cover for healthy growth sow about 12 seeds every foot of the row to witness desirable results.

When it comes to fertilizing, some experts suggest going for the soil test and adding manure depending on the outcome. However, for a layperson, if the plant grows slowly, add fertilizers or supplements in case of a pH imbalance. The need to keep the moist soil plays a leading role, so heavy mulching is always advisable; when the Spinach seedling sprouts, start thinning to about 3-4 inches apart, and anything more than can cause permanent damage due to its shallow roots. Growing Spinach indoors should not be the priority of any cultivator due to the risk of the transfer shock.

Pests and Pesticides for the Spinach:

  • Aphids are tiny insects, the biggest enemy for spinach cultivation, and get tackled using ladybugs. They feast on the aphids keeping the plant free from them. One can use sprays to kill the aphids, but that won’t fall under the organic category.
  • Cabbage Loopers: They attack the leaves and have a distinct grayish color to them. These caterpillars can prove detrimental to the plant’s health, and there are few ways to deal with them. One is picking them out of the plantation using hand or covering the entire cultivation using insect netting.
  • Cutworms: They are one of the most aggressive growing pests that attack spinach cultivation, and they look like light brown worms. Using Diatomaceous earth around the seedling helps the cultivator to keep these pests in check.
