Know Your Samphire Growing Season

Samphire is a tropical plant, which means it prefers warm temperatures and proper sunlight. As such, it will grow best in areas with a tropical climate. In North America, samphire is only profitable to grow from April through October. During the winter months, it will be too cold for your samphire plants to thrive. The leaves of the samphire will also die down over the winter and will only grow again in the spring.


To know when to plant your samphire, you first have to know when edible, ripe fruits are produced. The ripe fruits of samphire are purple or grey in color and change to a white color once they are ripe. When the fruits are ripe, they smell like an overripe melon and will crush easily with your thumb. Once you know when the edible fruits are ready, you can figure out when the samphire seeds will germinate best.

What You’ll Need To Grow Samphire

When starting a samphire garden, you will need to outfit your space with the following items:

  • ‍an area with enough sunlight for the samphire plants to thrive. this can be a balcony or a terrace on your property. ‍
  • a watering can. while samphire plants prefer well-drained soil, they can still grow well in lightly-drained soil if they have access to regular water.‍
  • a pair of scissors. you will need these to harvest the samphire crops.
  • ‍a colander or a colander tray. this will be used to wash the samphire crops.

Choose A Healthy Planting Spot And Prepare It Well

Before you plant your seeds, you will need to do some preparation work. as mentioned above, samphire prefers warm temperatures and a lot of sunlight. because of this, you will need a planting spot with a lot of sunlight exposure. However, this doesn’t mean you need to put your newly planted samphire plant in an open space. on the contrary, you need to find an area with well-drained soil and deep enough to prevent the roots of the samphire plants from getting shallow.

A good way to find an area with well-drained soil is to dig a hole with a diameter that is twice the length of your samphire plant’s height. when you are done with this, you should let the soil dry out for a few days. This will help the roots of your samphire plants to get a firm hold in the soil.

Plant The Samphire Seeds

After you have prepped your planting spot well, you can plant your samphire seeds. you can sow the seeds directly in the soil or you can germinate them in a container for a few days.

When you are ready to plant the samphire seeds, you can sprinkle them evenly on top of the soil and gently pat them down with your palms. Make sure the samphire seeds are not covered by any other soil particles so they get enough oxygen and water. you can transplant your samphire plants 2-3 weeks after they have germinated.

Keep A Close Eye On Your New Crop

You will have to give your samphire plants the same amount of attention as you would a regular vegetable crop. this means you should regularly water the samphire plants and remove any weeds that grow near their roots. you can also plant herbs near your samphire plants, as these herbs need less water than the samphire. you should also make sure your samphire plants receive sufficient sunlight and good air circulation.

Samphire is a salt-tolerant plant, which means that it can survive in areas with low levels of salt in the soil. however, you will have to regularly add sea salt to the soil to get the best results from your samphire garden. make sure to add at least one cup of sea salt to a gallon of soil when starting the samphire garden.

The Samphire Harvesting Process

Samphire is harvested once it is mature, which means it will flower in the fall and die in the spring. this means your samphire crop will start producing edible fruits in the fall, and then die in the spring. the best time to harvest your samphire crops is during the winter months when the temperatures are cooler and there is less risk of samphire dying due to the cold weather. during the winter months, when there is less risk of samphire dying from the cold, you can harvest the fresh, ripe fruits of the samphire crops.

Make sure to wash the harvested crops thoroughly with a colander or a clean cloth, as samphire is a salt-tolerant crop and the harvested samphire can contain salt. you can dry the harvested samphire in a sunny area, or you can store it inside your house to prevent it from getting wet.
