Growing squash in Zone 4 can be a rewarding experience when you choose the right companion plants. These plants not only enhance growth but also protect your squash from pests and diseases. Planning your garden with suitable companions ensures a healthy and productive squash harvest this April and beyond.

Why Companion Planting Matters for Zone 4 Squash

Companion planting involves growing different plants close together to benefit each other. For squash in Zone 4, which has a shorter growing season, selecting the right companions can improve pollination, deter pests, and improve soil health. This strategy maximizes space and promotes a thriving garden ecosystem.

Top Companion Plants for Your April Zone 4 Squash

  • Nasturtiums: These vibrant flowers repel squash bugs and aphids while attracting beneficial insects.
  • Marigolds: Marigolds release compounds that deter nematodes and beetles, protecting squash roots.
  • Radishes: Radishes can help repel squash vine borers and act as a trap crop for pests.
  • Herbs (Basil, Oregano, Dill): These herbs attract pollinators and beneficial insects, enhancing fruit set.
  • Beans: Legumes fix nitrogen in the soil, providing essential nutrients for healthy squash growth.
  • Sunflowers: Sunflowers attract pollinators and can serve as a natural trellis for climbing squash varieties.

Plants to Avoid Near Your Squash

  • Potatoes: These can promote disease transfer and compete for nutrients.
  • Strawberries: They may attract pests that also target squash and compete for space.
  • Fennel: Fennel can inhibit the growth of many garden plants, including squash.

Additional Tips for Growing Squash in Zone 4

Start your squash seeds indoors in early April to extend the growing season. When transplanting outdoors, ensure the soil temperature is at least 60°F (15°C). Mulching helps retain moisture and suppress weeds, while regular watering encourages healthy fruit development. Keep an eye out for pests and use natural deterrents like neem oil when necessary.
