How to Store Winter Squash

For some folks, harvest season brings hours and hours of canning, freezing, and drying to preserve crops for the colder months ahead. But if you’re looking for a crop that stores well all on its own, look no further than winter squash! Winter squash are versatile, nutritious, and can store for months.

Squash Hand-Pollination

Hand-pollination of squash ensures that the plants produce true-to-type seed and that the flowers are not contaminated by the pollen from another variety when the required isolation distance is impractical. Because the large male and female blossoms are easily distinguished, hand-pollinating squash can be easy for gardeners of all skill levels.

It’s National Weed Your Garden Day!

So maybe it doesn’t spark the excitement of National Doughnut Day (June 2) or National Chocolate Ice Cream Day (June 7) or even National Selfie Day (no, you haven’t missed that—it’s June 21). But here at Seed Savers Exchange, we think National Weed Your Garden Day—observed annually on June 13—has a whole lot going for it too.

What to Plant in Your Garden in June

Did you know you can still plant in your garden in June? Odds are good you’ve already transplanted your tomatoes and peppers and harvested lettuce or other greens to serve up fresh for dinner. Yes, your garden has sprung to life, but if you’re interested in more than just weeding and watering, plenty of crops are still ripe for planting in many regions of the United States.

Thinning Seedlings

What?! I have to toss some of these perfectly healthy seedlings I worked so hard to start? Which do I save and which do I not? That is the reaction of many a new gardener upon first learning that thinning seedlings is a necessary step to ensure healthy growth of plant starts. The reality is that, if left in crowded environs, your seedlings will eventually suffer.
