Landscape Logic: Still a lot going on in the garden

Here are some September tips for your garden:

• Fertilize the garden in September. Consider using an organic, alfalfa-based fertilizer.

• Wait a little longer to harvest winter squash, some melons and pumpkins. You will know when these plants are ready to pick when the ground spot – that’s where the plant touches the soil – turns from white to a creamy or yellow/gold color.



• Check carrots for size and harvest before they grow too large.

• Most root veggies can be harvested when they are quite small – or left in the ground to harvest later. They can last in the soil well into October and November and even longer if the soil is well mulched. Parsnips develop better flavor if left in the ground until after frost.

Participate in The Longevity Project

The Longevity Project is an annual campaign to help educate readers about what it takes to live a long, fulfilling life in our valley. This year Kevin shares his story of hope and celebration of life with his presentation Cracked, Not Broken as we explore the critical and relevant topic of mental health.



• To harvest mature onions, dig them up and leave them on top of the ground to dry out for a few days. When you bring them inside, keep them in a cool, dry place.

• Tomatoes are generally still looking good. But when the plants start to decline in vigor and appearance later this month, pick the fruit to ripen indoors. Tomatoes left to ripen on withering vines will be lacking in quality and flavor.

• Plant late-season lettuce and spinach if you haven’t done so already.



What’s that on the leaves?

You may see a powdery cast on pumpkin or squash plants or other veggies. This residue is likely powdery mildew that is common this time of year when we have a combination of warm days and cooler nights. While it makes the leaves somewhat unattractive, it’s nothing to worry about in terms of plant health. Mildew is a sign of the changing seasons.
