Buying Guide: Key Purchase Considerations
-
<li Compatibility with cucumber varieties: Choose companions that tolerate or thrive in similar sun, soil, and water conditions. Nasturtiums and borage generally prefer full sun and well-drained soil, which aligns with many cucumber crops.
<li Pest deterrence and pollination lift: Marigolds and nasturtiums provide pest deterrence, while borage and basil contribute to pollinator activity. Consider a mix that supports both deterrence and pollination for cucumbers.
<li Edibility and garden utility: Nasturtiums offer edible petals and leaves, useful for salads and garnishes. Basil provides culinary versatility and aromatic deterrence benefits in some crop mixes.
<li Growth habit and space planning: If space is limited, opt for compact varieties like Space Master 80 and place taller companions away from overcrowding cucumbers. Vertical supports can extend planting options for climbing cucumbers and vining nasturtiums.
<li Seed quality and promises: Look for non-GMO or heirloom seeds if you prefer open-pollinated attributes and resilience. Check germination rates as indicated by seed packets for realistic expectations.
<li Garden layout strategy: Plant companions in proximity to cucumbers to maximize the ecological benefits—pollinator-friendly flowers nearby, with pest-deterring species interspersed around the cucumber rows.
