Crisp cucumbers guaranteed: How to water properly in July!
With summer in full swing, many garden owners in Cologne are dreaming of a rich harvest of tasty cucumbers. But to achieve this, there are a few things you need to keep in mind, especially when watering properly. A hot topic in gardening: how to care for cucumbers to avoid bitterness in the fruits. [112] reports that warm water is best - cold water does not go into the watering can! The timing of watering is also important: morning or evening is optimal, preferably not in the blazing sun.
In July, cucumbers need particularly high water needs. It is advisable to give about ten liters of water per bush every day so that the moisture reaches the roots. Mulch is a proven way to retain moisture in the soil and protect roots. In order for the plants to thrive properly, fertilizers should not be neglected. A healthy nutrient balance ensures that the cucumbers remain crunchy and delicious.
A look at the cucumber
The cucumber (Cucumis sativus) has a long history and has been cultivated for over 3,000 years. Originally from India, it belongs to the pumpkin family (Cucurbitaceae). As the [Shire] site reveals, there are two main types: outdoor cucumbers, often used for pickling, and the popular salad cucumbers, also known as snake cucumbers. The modern varieties are mostly parthenocarpic, meaning they do not require pollination.
To grow really good cucumbers, you need a sunny, wind-protected location with humus-rich, loose soil. The pH value should be between 6 and 7. The optimal soil preparation involves incorporating 3-5 liters of compost per square meter, aerating the soil well and adding mulch. In order for direct sowing to be successful, the robust pickling cucumbers should be put outdoors from the end of April to the beginning of July. For snake cucumbers, it is recommended to pre-plant them in the greenhouse from mid-March.
The right fertilization
Once the soil is prepared, the exciting time of gardening begins. There is a lot to consider when fertilizing. [1and1] explains that organic fertilizers such as mature compost or well-rotted manure significantly improve the soil structure and nutrient release. Proper initial fertilization should occur 2-3 weeks after planting, with nitrogen being particularly important. Regular top dressing every two to three weeks is recommended throughout the entire growth period in order to provide the plants with the best possible support in their development.
The potassium requirement of cucumbers increases, especially during the fruiting phase. Organic potassium fertilizers such as vinasse or comfrey manure are ideal here. However, the following applies to all fertilization measures: Always pay attention to the soil conditions and weather conditions, as these can influence nutrient absorption.
Proper care is crucial for plants to develop their flowers and fruits. The yellow, funnel-shaped flowers turn into crunchy cucumbers if the gardener has a good hand. A few tips on watering and care times will help prevent pests such as aphids and spider mites. Spacing plants to improve air circulation and encourage beneficial insects such as ladybirds are excellent protective measures.
Anyone who takes all of this to heart can look forward to a bountiful cucumber harvest. The results of your own cultivation are not only fresh on the table, but also a great joy for every hobby gardener. Growing cucumbers is a rewarding experience with the right knowledge and a touch of patience!
