Growing Tips for Amsterdam

Start Indoors for a Head Start

Many crops like tomatoes, peppers, and pumpkins benefit from being started indoors to make the most of the relatively short growing season. Begin when outdoor temperatures are still too cool to give your plants a strong start.

Soil Care is Key

Aim for loose, humus-rich, and well-draining soil, especially with Amsterdam's often clayey soils. Regularly incorporating compost will improve soil structure and nutrient supply for plants like carrots and radishes.

Ensure Consistent Moisture

Many plants, such as radishes, broccoli, and pumpkins, need a consistent water supply to thrive and avoid stress. Radishes can become woody if they dry out, so regular watering is essential.

Make the Most of Light and Warmth

Heat-loving crops like onions, tomatoes, and basil prefer a full-sun, sheltered spot. Make sure they get enough light to ensure a bountiful harvest and promote ripening.

Common Pests & Diseases

•

Aphids

If you have an aphid infestation, you can rinse them off with a strong stream of water or spray the plants with a soapy solution (soft soap and water). Encourage beneficial insects like ladybugs by planting insect-friendly plants.

•

Slugs

Protect your young plants from slugs by installing slug fences or using iron phosphate-based slug pellets. Collect them in the evening or lure them with beer traps to remove them.

•

Powdery Mildew

If you spot powdery mildew, a white fungal coating, remove affected leaves immediately and dispose of them in household waste. A mixture of milk and water (1:8) can be sprayed on leaves as a preventative measure or for mild infestations to inhibit its spread.

•

Late Blight

To prevent late blight in tomatoes and potatoes, ensure adequate spacing between plants and avoid wetting the leaves when watering. Remove affected plant parts immediately to prevent further spread.
