Planting and Growing Conditions

The first step in growing spinach is to select the right seeds. You need to be familiar with the different varieties, as well as their height and overall size. Think about their flavor as well so that you will know which is ideal for your preferences. To prevent problems in the future, purchase only from reputable suppliers to have seeds that are disease-free. Unlike in the case of other vegetables, growing spinach from seeds will not require the need to wait for a long time before they will germinate.

Look for a container where you will plant the spinach. It should have a depth of at least six inches, providing the root with more than enough room to grow. If you are recycling an old container, wash it with mild soap and warm water to disinfect. Make sure that the pot is also wide enough. To add, there should be holes at the bottom, which will provide drainage to avoid water from accumulating and causing root rot.

Fill the pot with a nutrient-rich soil. Ideally, the pH level should be anywhere from 6.5 to 7.5. An organic potting mix will also be an excellent soil amendment, as well as compost. The latter will help in retaining moisture without making the soil soggy.

Sow the seeds on the surface of the soil, making sure to have one to two inches of space in between. If you are transplanting, on the other hand, six to eight inches of space will be necessary. Water the soil and press it firmly from the top.

Otherwise, the plant can experience bolting, a condition wherein leaves do not fully develop and become bitter or bland.

Since the leaves are the edible parts, the damage from these pests will make the crop unmarketable and unfit for human consumption.

Care and Maintenance

To take care of spinach and to guarantee its best condition until harvest, here are some important points you have to keep in mind:

  • Consistent moisture is one of the key ingredients for growing healthy spinach. With this, make sure that you water it consistently without overdoing. Too much water will encourage root problems.
  • Even if you grow spinach in containers, you should still add mulch. This will be helpful in the retention of moisture. Make sure to add organic matter, but be careful in doing this as this can be a method of transferring pests and infection to the plant.
  • Do not let the plant stay longer in the container than it should be. In most cases, they are ready to harvest within 37 to 50 days. Also, if it reaches a height of three to four inches and if there are five to six healthy leaves, you are ready to harvest.
  • Fertilizing is necessary to supplement the essential nutrients. If the weather is warm, soy meal, fish meal, and alfalfa meal will be ideal choices for natural fertilizers. Also, take note that spinach is a vegetable that feeds heavily, which is why the use of a fertilizer will help. Add fertilizer to the soil prior to sowing the seeds.
