Planting Tips For Heirloom Organic Summer Squash Seeds:

Heirloom summer squash are warm weather crops, as the name implies and the germination temperature verifies.  Only plant once the soil temperature warms to at least 70 degrees.  Mounding up small hills will create the right soil consistancy and allow the soil to warm quicker.  Mix in a shovelful of compost with handfulls of bone meal and wood ash to create the perfect soil environment for these heirloom seeds.

Plant 3-6 heirloom squash seeds per hill.  Once they have shown true leaves and grown in size, you should thin out to the 3 strongest plants.  Remember, harvest these summer squash continually in order to keep the plant producing.

Seed Care tips for Organic Heirloom Summer Squash:

Organic heirloom seeds are hardy but always take care with your garden seeds to give them the appropriate amount of moisture - not letting the vegetable seeds dry out prematurely or overwatering and possibly having them rot.
