Everything You Need To Know About Growing Cucumber


Cucumbers are a vining plant that is best grown on a trellis to keep the fruit off the ground and will make for an easier harvest.


Cucumbers are best grown in well-drained soil with full sun and a soil pH range of 6.0 through 6.5.

They can be sown straight into the soil after the last frost or started 8 to 10 weeks before the last frost indoors using a cardboard seed starting tray.

They are best planted in rows that are about 3 feet apart, about 6 inches apart in the row, and about one inch deep.

If using a trellis then the rows can be planted about 1 foot apart.

For best results, it is recommended before planting or sowing them to till compost into the soil which is known as amending the soil.

This will provide nutrients to the soil, helps with water retention, and will help to keep the soil loose which will make it easier for the roots to grow.


Cucumber seedlings should be fertilized with a high-nitrogen fertilizer such as 18-18-21 every two weeks to encourage plant growth.

One week after the plant blooms they are best fertilized with a low-nitrogen fertilizer that is high in phosphorus and potassium such as 3-4-6, or a homemade liquid fertilizer.

Fertilizer should be added every three weeks to encourage the growth of the fruit.

They prefer soil that is consistently moist but not soaked and they will require about 1 inch of water per week.


They are best harvested with a sharp pair of gardening shears to remove the fruit from the plant.

It is best to avoid twisting the cucumbers from the plant because this can cause damage to the plant.


Cucumbers are propagated through seed, therefore some plants should be set aside to have seed for the following season.


Cucumbers have several pests that feed on them but using natural methods such as attracting predators and natural insecticides such as essential oils, diatomaceous earth, or insecticidal soap will keep your pest control organic.

  • Aphids
  • Thrips
  • Whiteflies
  • Cucumber beetles
  • Cutworms
  • Slugs
  • Snails
  • Flea Beetles
  • Cabbage loopers
  • Pickleworms
  • Melonworms


If they are planted close together can develop mold and mildew issues during times of high humidity.

If this is the case then preventive measures may need to be taken.

  • Powdery mildew
  • Downy mildew
  • Angular leaf spot
  • Alternaria leaf spot
  • Cercospora leaf spot
  • Bacterial wilt
  • Fusarium wilt
  • Gummy stem blight
  • Root rot
  • Anthracnose
  • Phytophthora crown


Plant viruses are caused by pests causing damage to a plant, therefore good pest management is a must.

  • Blossom-end rot

As a kid, Joel found enjoyment in caring for the many houseplants he grew up with, learning how to transplant them safely, cloning them, and more. At about the age of 10, he wanted to see if he could sprout an orange seed from a store-bought orange and ended up using it as a science experiment in a school project. Throughout the many years of gardening, he has helped many friends and family set up their food and botanical gardens. After years of caring for plants, he was talking with other gardeners and discovering old methods of farming and botanical gardening. Joel has decided to share his knowledge for others to enjoy as he has for many years.
