It is a beautiful sight to behold when, in midsummer, an abundance of cucumbers are ripe and ready to pick. If plenty of sun and water is available, you can easily produce a plethora of potential pickles!

Seeds can be started indoors about 3 weeks before the last frost. Bottom heat and warm soil is an important factor in germination. Cucumbers will also do well directly sown into the garden, but don’t plant too soon. Soil must be at least 21°C for seeds to sprout. Multiple plantings can be made every two weeks to ensure a continual harvest throughout the season.

Choose a site in full sun with fertile well-drained soil. Seeds can be sown directly at a depth of 2 cm. Cucumbers should be given plenty of room to sprawl, space at about 90-150 cm apart. Unless you’re planning to grow vertically on trellises, then space plantings to 30 cm.

Water frequently when sprouts emerge, they will require about 2 cm of water/week. Apply a layer of mulch to retain moisture and to keep fruits from laying in the soil. Water slowly and carefully, foliage should remain dry in order to prevent leaf diseases like powdery mildew. It is a good idea to apply a liquid fertilizer around the base of the plants after they start flowering. Lightly fertilize every few weeks during the picking season.

Harvest cucumbers at the size appropriate to its variety so they don’t get bitter. Slicers are best at 15-20 cm and picklers at 5 cm. Search well and pick often. Fruits are often missed and can quickly swell up to inedible sizes. The constant harvest will promote more blossoms and fruit. Use a knife or pruners to clip cukes to prevent damage to the fruit and plant. Cucumbers come in many different shapes and sizes and can be so refreshing in the sweltering summer months. Why not plant enough to pick a few pecks?


- Cultivated for at least 3,000 years, the cucumber first originated from India. Charlemagne had cucumbers grown in his gardens in the eighth century. They were reportedly introduced into England in the early 14th century and North America by the mid-16th century.

- There are three main types of cucumber: slicing, pickling and seedless.

- A trellis usually provides a higher yield, but you can also use stakes.

- Cucumber seeds will remain viable for 5 years if stored in a cool, dark place, ideally between 4 and 10⁰C. After that, the germination rate may start to go down. 


You know that a lush, fruitful garden needs good soil, frequent watering, and sunlight to grow, but it’s the seeds that really make the harvest.

Picked and bagged for 2024 the vast majority of our seeds have germination rates of over 85%. The seeds are all-natural, non-GMO, non-hybrid, untreated, and open-pollinated for seed saving.

We have put a lot of thoughts into the design and packaging of our seed packets. Our seeds are all carefully packed in food grade kraft paper/aluminium zipper lock bags, and then are shipped in eco-friendly padded mailers.

We heat-seal each of our seed packet for even more protection from moisture, odour and light, allowing you to store your seeds for up to 3x longer than paper or plastic. Plant them all, germinate some indoors, save some for next season - it’s up to you!
