How to grow cucumbers in Perth, WA:
Follow the following guide for growing cucumbers at home in the backyard or garden. Make sure you have ample room.

1. Choose a spot in the garden which is full sun and enrich the soil with a quality dynamic lifter and soil improver.
2. Sow 4-6 seeds into mounds of moist soil spaced 40cm apart and water well.
3. As your cucumber seedlings grow, thin seedlings and leave only the two strongest. Mulch around the base of the plant with organic mulch like pea straw to retain moisture.
4. Feed weekly with a liquid plant food that is suitable for vegetables.
5. To save space, train cucumber vines to grow on a fence or trellis – tie young stems to a wire support and eventually, the tendrils will cling to the wire.
6. Pick fruit regularly to encourage a longer harvest window.

Growing cucumbers in pots:
Cucumbers grow best in the garden, but can still grow well in pots.

1. Choose a pot at least 40cm wide and deep. Position in full sun and protect from strong winds.
2. Fill pot with quality potting mix
3. Sow 4-6 seeds, cover lightly and water well.
4. Feed weekly with liquid plant food that is suitable for vegetables.

How to propagate cucumbers:
Cucumbers can be propagated by collecting seeds from mature cucumbers.

1. Cucumbers are eaten as immature fruits. When cucumbers are grown for seed allow them to grow beyond market-mature size. Cucumbers should lose their firmness and often change colour to yellow or orange. It is best to wait several weeks after this colour change before extracting the seeds.
2. If weather and plant health allow, the fruits can be left on the vine in the garden while they continue to mature and soften. Mature cucumbers will pull easily from the vine when ripe.
3. Cut cucumbers in half lengthwise to extract the seeds. Scoop out seeds and any surrounding pulp from the seed cavity. Place this mixture of seeds and pulp into a small bucket or jar with some water. The mixture needs to undergo fermentation for 1-3 days to remove the pulp from the seeds. The fermenting mixture should be held in an open container at temperatures between 21-26 degrees Celsius.
4. When fermentation is complete, decant the seeds by adding more water to the container and stirring the mixture – the pulp and lightweight seeds will float to the top and can be poured off, leaving only viable seeds which will have settled at the bottom of the container. Rinse clean the viable seeds, before drying on a coffee filters or paper towel until they can be cleanly snapped in half.
5. Store cucumber seeds in a cool, dark, and dry place in an airtight container. It is important that no moisture and humidity impact the seeds. Stored correctly, cucumber seeds will remain viable for 5 years.

Depending on your variety of cucumber. Harvest your cucumbers as soon as they are ripe, Regular harvesting will encourage your plants to produce more. Cut the ripe cucumbers away from the vine using a sharp knife.

Cucumber companion plants:
There are many vegetables that make excellent companions for cucumbers. Peas, corn, beans, and lentils to name a few. Legumes area good good choice as their root system that increases nitrogen in the soil.

Because vining cucumbers need a trellis to keep the fruit off the ground and prevent diseases, corn or sunflowers are also a good option as they can act as a natural trellis for cucumber vines.

Snails and slugs will attack young seedlings. Protect your cucumbers using snail and slug pellets. Fungal infections such as powdery mildew or downy mildew can become a problem during the growth cycle. Remove infected leaves and spray with a suitable organic fungicide.
