Growing Tips for Stuttgart

Consistent Moisture is Key

Many plants like kohlrabi, chard, and broccoli need a constant water supply for optimal growth and bulb formation. Especially during dry spells, make sure the soil stays consistently moist to prevent stress.

Prepare Your Soil for a Bountiful Harvest

Deep, loose, and humus-rich soil is the foundation for healthy plants like carrots and chard. Before sowing or planting, work in plenty of compost to improve nutrient supply and soil structure.

Protect Cold-Sensitive Crops

Warm spots are essential for courgettes, aubergines, and tomatoes, as they are very cold-sensitive. Only plant them out after the Ice Saints and, if necessary, provide protection from cool nights.

Lettuces as Versatile Gap Fillers

Lettuces like garden lettuce or endives are excellent for quickly utilising empty beds. By choosing the right varieties, you can harvest fresh lettuce almost all year round, just make sure they get enough moisture.

Common Pests & Diseases

•

Naturally Combat Aphids

If you have an aphid infestation, you can spray the plants with a strong jet of water or a soapy solution. Beneficial insects like ladybirds and lacewings are natural predators and should be encouraged in your garden.

•

Keep Slugs in Check

Slugs are a nuisance, especially for young plants. Regularly pick them off, install slug fences, or use iron phosphate-based slug pellets, which are safe for pets and hedgehogs.

•

Prevent and Treat Powdery Mildew

Powdery mildew often appears in humid weather. Ensure good air circulation between plants and remove affected leaves immediately. Spraying with a milk-water mixture can also help control the fungus.

•

Healthy Soil, Healthy Plants

Vibrant soil with a rich humus content strengthens plants from within, making them more resistant to diseases and pests. Regular mulching and the use of compost promote soil life.
