Growing Tips for Lisbon

Embrace Year-Round Growing

Many cold-hardy plants like lettuce, Swiss chard, or radishes can be grown almost year-round in Lisbon. Take advantage of the mild winter months for continuous harvests and fresh veggies.

Manage Your Watering

Especially during the dry summer months, ensure consistent and adequate watering, as many plants like radishes, cucumbers, or eggplants prefer moist soil. However, always avoid waterlogging.

Choose Sunny Spots

Most vegetables like tomatoes, peppers, onions, and herbs like basil love full sun and warmth. Choose the sunniest spots in your garden or on your balcony for them to achieve optimal yields.

Enrich Your Soil Regularly

Heavy feeders like zucchini, eggplants, or tomatoes benefit from nutrient-rich, humus-filled soils. Before planting, work in compost or organic fertilizer to ensure a good harvest and promote soil health.

Common Pests & Diseases

•

Combat Aphids

If you have an aphid infestation, you can spray the plants with a strong stream of water or use a soapy solution (soft soap and water). Beneficial insects like ladybug larvae are natural helpers and should be encouraged.

•

Keep Slugs Away

Protect your young plants from slugs by installing slug fences or setting up beer traps. Regularly remove slugs, especially after rain, to prevent major damage.

•

Prevent Fungal Diseases

Ensure good air circulation between plants and avoid overhead watering to prevent fungal diseases like powdery mildew. Remove affected leaves immediately to stop them from spreading.

•

Avoid Root Rot

Ensure well-draining soils and avoid waterlogging, especially for plants sensitive to too much moisture. A drainage layer can be helpful here to keep roots healthy.
