Task 1: Propagating Strawberries

Late summer or early autumn is the perfect time to plant a new strawberry patch or expand an existing one. If your strawberry patch has faced challenges like mine with slugs, consider relocating it. Learn how to propagate new plants from runners for a fresh start.

As we transition from summer to autumn, it’s time to think about the sweet rewards of strawberries in your garden. While many gardeners primarily associate this season with harvest, it’s also an opportune moment to plan for the future. If you’ve been nurturing a strawberry patch, you may have noticed wiry stems known as “runners” emerging from your strawberry plants. These runners are nature’s way of offering you new strawberry plants without the need to purchase more.

Propagating Strawberry Runners:

1. Identify the Runners: After late summer, when the strawberries have finished producing fruits, you’ll often spot these runners with tiny plantlets along their length.

2. Gather Supplies: To propagate these plantlets, you’ll need thick-gauge wire, cut and bent into little U-shaped pins.

3. Pin Them Down: Gently pin the runners either directly into the soil or into pots filled with potting mix. Ensure that the plantlets make contact with the soil or mix.

4. Regular Care: Periodically check on the pinned runners to ensure they stay in place and keep them well-watered. These plantlets should take about a month to root into the potting mix.

5. Overwintering: Once they’ve established roots, cut them free from the mother plants and overwinter them in either a greenhouse or a cold frame. Come spring, they’ll be ready for planting.

If you find that your runners have already rooted into the soil and you want to relocate them, that’s not a problem. Carefully dig them up, pot them, and let them grow on. Overwinter these transplants for spring planting.

Propagating strawberries not only ensures a healthy future harvest but also allows you to expand your strawberry patch inexpensively. It’s a simple yet rewarding task that promises the sweet taste of success in the seasons to come.

Task 2: Elevating Winter Squash and Pumpkins

To prevent damp soil from causing fruit rot, lift developing winter squash and pumpkins off the ground and place a tile or slate underneath them. This simple trick can protect your harvest.

As the transition from summer to autumn unfolds, it’s essential to pay special attention to your growing winter squash and pumpkins. These hearty vegetables are a staple of autumn and winter meals, but they require some care to ensure they reach their full potential.

One common issue that can affect these crops is fruit rot caused by contact with damp soil. To safeguard your precious harvest and ensure your winter squash and pumpkins ripen beautifully, consider the following technique:

Elevating Winter Squash and Pumpkins:

1. Identify Developing Fruits: As your winter squash and pumpkins begin to form and grow, keep an eye on them. Look for any signs of contact with the ground, which can lead to rot.

2. Prepare Tiles or Slates: Gather a collection of tiles or slates, preferably ones that are clean and free from any contaminants.

3. Lift and Support: Carefully lift each developing fruit and place a tile or slate underneath it. Ensure that the skin is no longer in contact with the damp soil.

By elevating your winter squash and pumpkins, you reduce the chances of fruits spoiling or rotting due to moisture. This straightforward technique can make a significant difference in the quality of your harvest.

As autumn progresses, and the days grow cooler, you’ll be able to enjoy the fruits of your labor, knowing that your winter squash and pumpkins are ripening beautifully and are well-protected from damp soil.

Task 3: Seed Saving for Self-Sufficiency

Towards the end of the month, allow some plants, like beans and tomatoes, to fully mature for seed saving. Discover the art of preserving seeds from various vegetables, ensuring a sustainable source for future planting.

As the gardening season draws to a close, it’s time to embrace self-sufficiency in your garden. One of the most rewarding practices for a dedicated gardener is seed saving. By saving seeds from your best-performing plants, you not only ensure a continuous source of future crops but also establish a deeper connection with your garden’s life cycle.

Here are some steps to get you started on the journey of seed saving:

1. Identifying the Right Candidates:

• Towards the end of September, select healthy, robust plants that you want to save seeds from. Beans, tomatoes, peppers, and lettuce are excellent candidates for seed saving.

2. Allowing Seeds to Mature:

• Leave some of these chosen plants untouched as they continue to grow. Allow the fruits to fully ripen on the plant.

3. Harvesting Seeds:

• Once the fruits have reached maturity, they will naturally begin to dry and change color. For instance, beans may turn papery, and tomatoes will become mushy.

4. Extracting Seeds:

• Extract the seeds from the mature fruits. For beans, simply shell the beans and bring them indoors for further drying. For tomatoes, scoop out the seeds along with the surrounding gel-like substance and place them in a container.

5. Drying and Storing Seeds:

• Spread the seeds in a single layer on a paper towel or a screen and let them air dry completely. Once dry, store the seeds in a cool, dry place in labeled envelopes or containers.

It’s worth noting that some vegetables like onions, leeks, chard, and carrots won’t produce seeds until the following season. For these, you’ll need to overwinter a few plants so they can flower and produce seeds next year.

By saving seeds from your garden, you not only reduce expenses but also ensure that your crops are well-adapted to your specific growing conditions. Self-saved seeds are fresher, more cost-effective, and uniquely suited to your garden, making them a valuable asset for any dedicated gardener.

Task 4: Clearing and Preparing for the Next Crop

With the growing season ending for some crops, it’s time to clear them quickly to make room for new plantings or soil improvement. Explore the process of clearing, weeding, and enriching your garden beds.

As the season shifts from summer to autumn, your garden undergoes a transformation. Some crops reach the end of their productive cycle, creating an opportunity for you to prepare your garden beds for the next planting season. Clearing and rejuvenating your garden beds is a crucial task to ensure the ongoing success of your garden.

Here’s a step-by-step guide on how to clear and prepare your garden beds:

1. Clearing the Old Crop:

• Begin by removing all remnants of the old crop. Pull out any remaining plants, including their roots, and place them in your compost heap.

2. Removing Weeds:

• While clearing, be sure to pick through any traces of the old crop, along with any annual weeds that may have sneaked in. These make excellent additions to your compost pile.

3. Adding Organic Matter:

• After clearing away the old crop and weeds, it’s time to improve your soil. Add organic matter to your garden beds. Aim for a depth of at least an inch or 3 cm if possible. Well-rotted manure is an excellent choice for this purpose.

4. Preparing for the Next Crop:

• If you’re planning to plant a new crop immediately, prepare the soil accordingly. Mix the organic matter into the soil to ensure it’s well-distributed.

5. Planting Your Next Crop:

• Once your garden bed is prepared, it’s time to plant your next crop. Choose vegetables or flowers suitable for the season and your growing region. In this guide, I’m planting beautiful chard that will provide harvests throughout the winter and into spring.

Remember to consider the specific needs of the plants you’ll be growing in the next season, including spacing and sunlight requirements.

Clearing and preparing your garden beds is an essential step to maintain healthy soil and optimize the growing space in your garden. By following these steps, you’ll set the stage for a successful and productive gardening season ahead.

Task 5: Planting Spring-Maturing Cabbage

Consider making space for spring-maturing cabbage in your garden. These hardy plants benefit from the frozen conditions of winter, which makes the leaves sweeter. Plant seedlings and protect them from pesky pigeons.

While autumn ushers in cooler temperatures and shorter days, it also presents an opportunity to plan for the future. One vegetable worth making space for in your garden is spring-maturing cabbage. These resilient plants not only thrive in winter’s chill but also develop sweeter leaves as a result of the frost.

Here’s how to go about planting spring-maturing cabbage:

1. Preparing the Garden Bed:

• Choose a well-drained, sunny location in your garden bed for planting cabbage seedlings. Ensure the soil is enriched with compost or well-rotted manure.

2. Selecting Seedlings:

• Look for healthy cabbage seedlings at your local nursery or garden center. Spring cabbage varieties are typically suitable for planting in early autumn.

3. Planting Seedlings:

• Dig small holes in your prepared garden bed, spacing them about 12 inches or 30 cm apart in both directions. Plant the cabbage seedlings in these holes, ensuring they are at the same depth as they were in their pots.

4. Protection from Pigeons:

• Cabbage plants can be a favorite snack for pigeons. To protect them, consider using bird netting or mesh to create a barrier around your cabbage patch.

5. Watering and Care:

• Keep the soil consistently moist, and provide ample sunlight for your cabbage seedlings to thrive. Watering in the morning allows any moisture on the leaves to dry before evening, reducing the risk of fungal diseases.

Spring cabbage not only survives but thrives in the freezing conditions of winter, resulting in sweeter and more flavorful leaves. By planting now, you’ll be rewarded with fresh cabbage when other vegetables are scarce, extending your harvest well into spring.

Task 6: Prepare for Cooler Nights

As the evenings grow cooler, remember to shut greenhouse doors and windows by late afternoon to retain daytime heat. Extend the ripening season for peppers and tomatoes by trapping warmth.

With the arrival of autumn, we can expect cooler evenings and the occasional nip in the air. To ensure your garden remains a warm and nurturing environment for your plants, it’s essential to prepare for these cooler nights. This is particularly important if you have a greenhouse, as it can make a significant difference in extending the ripening season for crops like peppers and tomatoes.

Here’s what you need to do to prepare for cooler nights in your garden:

One highly effective and eco-friendly way to do this is by sowing cover crops or green manure. These crops offer a range of benefits, including improving soil fertility, suppressing weeds, and enhancing soil structure, all while your garden beds lie fallow.

Here’s a guide to sowing cover crops or green manure in your garden:

1. Choose the Right Cover Crops:

• Select cover crops that are well-suited to your climate. In temperate regions, options like mustard, winter tares or vetch, grazing rye, and field beans are popular choices. These crops can be sown in late summer or early autumn.

2. Interplanting with Established Crops:

• Some cover crops can be sown in between already established crops. This technique allows the cover crop to grow alongside your main crops. For instance, nitrogen-fixing trefoil can be sown among your existing kale plants.

3. Mat Formation and Winter Growth:

• As these cover crops grow, they’ll form a protective mat over your garden bed. This mat not only helps suppress weeds but also adds organic matter to the soil.

4. Incorporating in Spring:

• In spring, as your garden begins to awaken, you can easily incorporate these cover crops by turning them into the soil. This process enriches the soil with nutrients and enhances its structure.

Cover crops are an excellent, low-tech solution to maintaining healthy soil during the off-season. They provide an eco-friendly alternative to chemical fertilizers and contribute to the long-term health of your garden. By sowing cover crops or green manure, you’re investing in the future fertility and productivity of your garden.

Task 8: Harvesting Late-Season Potatoes

Before slugs can reach them, dig up the last of your spring-planted potatoes. Properly store these potatoes in a cool, dark, and airy place to enjoy them throughout the season.

Late summer is a time of abundance, and if you’ve planted potatoes in the spring, it’s time to reap the rewards of your labor. However, you’ll want to act swiftly to harvest your potatoes before slugs or other pests have a chance to damage them. Once harvested, storing your potatoes properly ensures they stay fresh and delicious throughout the season.

Here’s how to harvest and store late-season potatoes:

1. Identifying Readiness:

• Start by checking if your potatoes are ready for harvest. This is typically when the foliage begins to die back and turn yellow. It’s a sign that the potatoes have reached maturity.

2. Digging Up Potatoes:

• Gently dig up the potato plants, being careful not to damage the tubers. Use a garden fork or shovel to lift the plants from the soil.

3. Drying the Potatoes:

• After digging up the potatoes, leave them on the soil surface for a few hours. This allows the skins to dry, making them less susceptible to damage during storage.

4. Proper Storage:

• Store your potatoes in breathable sacks or baskets in a cool, dark, and airy place. A basement, cellar, or cool pantry is ideal. Avoid storing them in the refrigerator, as this can change the potato’s texture and flavor.

Late-season potatoes offer a delightful addition to your autumn and winter meals. By harvesting and storing them correctly, you’ll have access to your homegrown potatoes for a more extended period, allowing you to enjoy the taste of your garden well into the season.

Task 9: Continuous Harvest of Warm-Season Crops
