Aphids

Aphids are tiny insects that suck the sap from your potato plants, causing stunted growth and potentially transmitting diseases. To control aphids, you can manually remove them by spraying your plants with a strong jet of water or by using insecticidal soap. Alternatively, planting companion plants such as marigolds or nasturtiums can help repel aphids.

Potato Beetles

Potato beetles are notorious pests that defoliate potato plants and can quickly devastate your crop. To control these beetles, hand-pick them off your plants and destroy them. Applying organic insecticides containing neem oil or Bacillus thuringiensis (BT) can also be effective.

Blight

Blight is a fungal disease that affects potato plants, causing brown lesions on leaves and tubers. To prevent blight, avoid overhead watering and provide good air circulation around your plants. If blight does occur, remove and destroy infected plants to prevent the spread of the disease.

Wireworms

Wireworms are the larvae of click beetles and can cause damage to potato tubers, making them inedible. To reduce the risk of wireworm infestations, you can add beneficial nematodes to the soil before planting your potatoes. Additionally, rotating your crops and keeping your garden weed-free can help minimize the presence of wireworms.

Mice And Voles

Mice and voles are known to feed on potato tubers, leading to significant crop losses. To deter these pests, consider using mouse traps or installing wire mesh cages around your potato bags. Making your garden less attractive to rodents by removing potential shelter and food sources can also help.

Harvesting And Storing Potatoes Grown In A Bag

After months of tending to your potato plants, the time will come to harvest your tubers. Harvesting potatoes from bags is a straightforward process. Here’s how to do it:

1. As the plants start to yellow and die back, carefully reach into the bag and gently remove a few potatoes. These early potatoes are often referred to as "new potatoes" and can be enjoyed immediately.

2. To harvest the main crop, wait until the foliage has completely died back. This allows the potatoes to fully mature and develop thicker skins, which improves their storage quality.

3. Start by gently tipping the bag over to loosen the soil. Take care not to damage the potatoes while doing this.

4. Once the bag is tipped over, you can carefully reach into the soil and pluck out the potatoes. Avoid stabbing or cutting the tubers with your tools, as this can introduce pathogens and reduce their shelf life.

5. Inspect your harvest for any signs of damage or disease. Remove any damaged or diseased potatoes, as they can cause others to spoil during storage.

Now that you have harvested your potatoes, it’s time to store them properly to ensure they last as long as possible. Here are a few tips for storing potatoes:

1. Cure the potatoes by placing them in a cool, dark, and well-ventilated area for about two weeks. This allows the skins to toughen up and any minor cuts or bruises to heal.

2. After curing, sort the potatoes by size and quality. Set aside any damaged or diseased potatoes for immediate use, as they won’t store well.

3. Choose a storage location that is cool (around 45-50°F or 7-10°C), dark, and free from humidity. Avoid storing potatoes near onions or apples, as these can release gases that speed up spoilage.

4. Use breathable containers such as burlap sacks or mesh bags to store your potatoes. Avoid plastic bags or airtight containers, as these can trap moisture and promote rot.

5. Regularly inspect your stored potatoes and remove any that show signs of spoilage. This prevents the spread of rot and ensures the longevity of your stored crop.
