Any tips on what vegetables would be best to plant during this season and how to prepare the soil would be greatly appreciated!” Cheers, Michael, Portland, USA.

How Do I Prepare My Garden For Fall Planting?

Hi Michael! It’s fantastic that you’re getting your kids involved in backyard farming. Fall is a wonderful time to garden, as the cooler weather can often lead to a bountiful harvest. Here’s a detailed guide on how to get your garden ready for fall planting.

Assess Your Current Garden

Before diving into any new planting, it’s important to take stock of your existing garden. Check which plants are still producing, which ones are past their prime, and what needs to be cleared out.

• Remove Spent Plants: Clear out any plants that have stopped producing. This helps reduce the spread of diseases and pests that might have taken up residence.
• Harvest Remaining Produce: Collect any lingering vegetables. This can include late tomatoes, peppers, or beans that are still good.
• Weed Thoroughly: Ensure all weeds are removed to prevent them from competing with your fall crops for nutrients and water.

Prepare the Soil

Good soil preparation can make a big difference for your fall crops. Healthy, well-prepared soil will make your plants more resilient and productive.

• Test Your Soil: If you haven’t done so recently, perform a soil test. This will let you know its pH and nutrient levels so you can amend it appropriately.
• Add Compost: Work in generous amounts of compost or well-rotted manure. This improves soil structure, adds nutrients, and enhances water retention.
• Aerate the Soil: Turn your soil over to a depth of about 6-8 inches. This helps to break up any compaction and allows roots to penetrate more easily.
• Mulch Well: Cover the prepared soil with mulch to retain moisture, regulate temperature, and prevent weeds.

Choose the Right Fall Crops

Selecting the appropriate vegetables for fall planting in Portland is key. Cool-season crops thrive best in the autumn months.

• Leafy Greens: Spinach, kale, and Swiss chard are excellent choices. They grow quickly and are very frost-tolerant.
• Root Vegetables: Carrots, beets, radishes, and turnips can be planted as they do well in cooler temperatures.
• Brassicas: Broccoli, cauliflower, and Brussels sprouts are great fall crops, though they might need a bit of protection from early frosts.
• Alliums: Garlic and onions can be sown now for a spring harvest.

Planting Tips

Once you’ve prepared your soil and chosen your crops, it’s time to plant. Here are some tips to ensure successful growth:

1. Plant at the Right Depth: Seeds and transplants should be planted at the correct depth specified on their planting instructions.
2. Spacing: Ensure adequate spacing between plants. Crowding can lead to poor airflow, which increases the chance of disease.
3. Water Consistently: Fall weather can be unpredictable, but consistent watering is vital, especially during dry spells. Use a soaker hose or drip irrigation for best results.
4. Protect Young Plants: Use row covers or cloches to protect seedlings from early frosts.

Maintain Your Garden

Once your plants are in the ground, ongoing maintenance will help ensure a successful fall harvest.

• Fertilize Wisely: Use a balanced organic fertilizer or compost tea, especially for heavy feeders like broccoli and cauliflower.
• Watch for Pests: Keep an eye out for fall pests like aphids and caterpillars. Hand-picking pests and using natural repellents can help keep your garden healthy.
• Mulch Again: Add another layer of mulch if necessary to keep the soil insulated and moist as the weather cools.
• Prune and Thin: Regularly prune leafy greens and thin out root crops to encourage stronger growth.

Utilize Season Extenders

To further extend your growing season, consider using season extenders. These can help protect your plants from early frosts and keep them productive longer.

• Cold Frames: Build or purchase cold frames to shelter your plants from cold weather while letting in sunlight.
• Row Covers: Lightweight row covers can provide an extra layer of protection without overheating your plants.
• Greenhouses and Tunnels: Investing in a small greenhouse or hoop tunnel can significantly extend your growing season.

Plan for Future Seasons

As you’re working on your fall garden, take some time to think ahead to spring. Planning and preparing now can set you up for success next year.

• Cover Crops: Sow cover crops such as clover or rye to improve soil health over the winter. These can be tilled into the soil in the spring.
• Garden Layout: Consider how your garden layout worked this year and what adjustments you might make for next season. Rotating crops helps prevent disease and pest build-up.
• Tool Maintenance: Sharpen and clean gardening tools before storing them for the winter. Proper maintenance will make them last longer and easier to use when planting resumes.

Involve the Kids

Since you mentioned you’re starting this with your kids, here are some child-friendly gardening activities to keep them engaged:

• Planting Seeds: Teach them how to plant seeds correctly and explain the importance of depth and spacing.
• Watering Duties: Assign them the task of watering the garden. Show them how to check soil moisture and avoid overwatering.
• Weeding: Make a game out of weeding, giving rewards for each weed pulled correctly.
• Harvesting: Let them help with harvesting vegetables. They will love seeing the fruits of their labor!

Final Thoughts…

Michael, thanks for your wonderful question. Gardening in the fall can be incredibly rewarding, especially when you prepare your garden properly and choose the right crops. Remember to keep the soil healthy, maintain your plants carefully, and use season extenders to maximize your harvest. Don’t forget to involve your kids—they’ll learn valuable skills and develop a love for gardening. Best wishes for a bountiful fall garden!
