Certain vegetables, such as tomatoes and peppers, should be grown together during a particular season. Planting same-season vegetables together ensures a bountiful harvest throughout the period since each vegetable typically matures at a slightly different time. Cool season vegetables should never be planted with warm season types and visa versa since high or low temperatures can quickly kill off or doom certain vegetables. Planting like-vegetables together, such as tender or frost tolerant varieties, is also commonly employed in home gardens. Certain crops also do better in containers than others, so growing those types together is also recommended.
Warm Season Vegetables
Warm season vegetables should be planted well after the threat of frost has passed in a region. They thrive in warmer soils and temperatures and typically will suffer if cooler temperatures prevail for a longer period of time than expected. Vine crops such as cantaloupe and cucumbers should be planted and grown together. Peppers, tomatoes, beans and eggplant are also popular warm season vegetables that can be grown together. These vegetables should be planted in well-draining soil in a region that receives full sun exposure. Adequate water is required, but be careful not to wet the plant too much as this can lead to over-watering. Harvest crops once they become ripe to encourage additional production of fruit throughout the rest of the season.
Cool Season Vegetables
Cool season vegetables are generally tolerant of frost and should be planted together for best results. These vegetables can be planted much earlier than warm-season types, typically several weeks before the last frost has settled. Cauliflower, carrots, broccoli, cabbage, asparagus, spinach, peas and lettuce are all hardy cool season vegetables that do well when planted together in the cool seasons of spring and fall. Root crops and leafy vegetables typically do well in partial shade, so grow these types together in the shadier regions of the garden to reserve full sun areas for warm-season fruits and sun-loving plants. Harvest time for cool-season vegetables vary, but leafy types can generally be picked once the leaves are of usable size.
Several vegetables are suitable for container planting and should be grown together in container gardens. Tomatoes typically do well in containers provided they have adequate sun, drainage and room for root development. Peppers, zucchini and green onions are also good choices for container gardens. Some leafy vegetables such as spinach and lettuce do well in containers and can be grown together as well. Be sure to plant vegetables in 3-to-5 gallon pots for optimal growth. Apply fertilizer for additional nutrients since the plant is not able to receive them from the ground soil.
