I would love to share what I have learned on how to grow spinach indoors, both from research and personal experience. If you have been looking for information about indoor spinach growing, steps that will lead to healthy plants and an abundant return are discussed below.
What You Need to Grow Spinach Indoors?
Growing spinach indoors is considerably different from outdoor cultivation. For a successful indoor spinach growing endeavor, you need some essential supplies.
Growing the Spinach
Spinach growing is quite straightforward and doesn’t really involve any complicated step. I’ve broken up the whole process into these easy steps.
Choose Suitable Pots and Fill With Soil
While it is not absolutely compulsory to use a pot, you can use trays and other containers. I’ve only ever grown spinach in pots. Depth is more important than width, so what you need are deep pots. I recommend pots that are at least six inches deep.
Also, spinach doesn’t do well in waterlogged conditions, and you should go for pots with small holes at the bottom. This is, however, not compulsory. Fill the selected containers with soil up till near the brim of the pots.
If you are planting in pots, go ahead to sow the seeds at a depth of half an inch, leaving about five inches of space between each seed. However, if you anticipate small leaves in your spinach plants, the spacing can be reduced to two or three inches. Varieties that typically have wide leaves need more spacing than those that have small leaves.
One of the reasons why spinach does well indoors is because it doesn’t require too much direct sunlight. In autumn, when sunlight is not so intense and the days are considerably shorter, you can put the place the pots at your window sill. However, in summer and spring, you should put them away from direct sunlight. In situations where there is not sufficient lighting, grow lights should be used.
While spinach plants do not need much sunlight, they still require sufficient lighting for photosynthesis. If the plants do not get sufficient natural lighting indoors, you should grow them under grow lights. There are many grow light types to choose from. From my personal experience, however, LED grow lights are the best for indoor growing.
At the early germinating stage, any temperature from 40°F to 80°F suitable. Nevertheless, the best soil temperature range at which you should grow spinach is 50°F – 80°F. Admittedly, some varieties will survive outside this temperature range, but this is the typical optimal temperature range. Never forget to adjust your thermostat to the appropriate temperature when growing spinach indoors.
Water the Plant
Spinach does not need much water. This doesn’t mean that you shouldn’t water the plants from time to time. Water until the soil is moist and not necessarily water-logged. This is why the soil mix you plant in should not be too water-retentive.
I wouldn’t say that mulching is compulsory indoor spinach growing. However, I put in all the effort I can to ensure healthy plant development. Retain soil moisture and improve soil fertility by applying an organic layer of mulch to the soil surface.
Use either fertilizer or manure to enrich your soil. Manure is not always readily available, so you can always apply nitrogen-based fertilizer. You need to be wary of timing when applying fertilizer. Apply when the plant is in the early development stages, not when it has stopped growing.
Typically, spinach takes a little over a month to reach full maturity and be ready for harvest. However, it can take up to 50 days. It is really important to harvest as soon as they reach full maturity or soon before they do. If you don’t harvest as soon as you should, you will notice small yellow or green flowering popping out; at this stage, the spinach leaves will begin to taste bitter.
Best Spinach Varieties to Grow Indoors
There are so many spinach classifications, but they all fall under three main varieties that have many more sub-varieties. In proper conditions, these three main varieties can be grown indoors.
Apparently, growing spinach indoors is not so complicated. I hope you found this step by step guideline useful. All you need is sufficient space, good lighting, and additional soil nutrients from fertilizer/manure. Furthermore, you need to be sure that the variety you plant to grow will do well in your climate. All in all, growing spinach indoors is not so complicated.
