Preparing for Harvest
Signs That Your Potatoes Are Ready to Harvest
As the growing season progresses, it’s essential to be vigilant about the signs that indicate your potatoes are ready for harvest. In New Zealand, the timing can vary depending on the potato variety, but several universal indicators can help you determine when to dig into your potato grow bags.
One of the most notable signs is the yellowing of the leaves. When the foliage begins to turn yellow and die back, it signals that the plant is diverting its energy from foliage growth to tuber development. This is a clear indication that your potatoes are reaching maturity. Additionally, you might notice that the flowers have dropped off. Flowering is a natural part of the potato plant’s life cycle, and once the flowers fade, it’s usually a sign that the tubers are developing underground.
Another useful tip is to gently peel back the top of the grow bag and check the size of the potatoes. If they are roughly the size of a golf ball or larger, they are likely ready for harvesting. However, it’s essential to remember that different potato varieties have distinct maturation times. For instance, early varieties like ‘Cliff’s Desire’ may be ready in as little as 10 to 12 weeks, while late varieties like ‘Agria’ may take up to 20 weeks or more.
Timing Your Harvest
Timing your harvest correctly is crucial for obtaining the best quality potatoes. In New Zealand, the ideal time to harvest generally falls between late summer and early autumn, depending on the variety you have planted. For early potatoes, aim to harvest them when the plants have flowered and the foliage begins to yellow. This usually occurs around December to January.
Mid-season varieties, such as ‘Rua’, should be harvested when the foliage starts to die back, typically around February to March. Late varieties, like ‘Agria’ or ‘Moonlight’, can be left in the ground longer, often until late March or April, allowing them to develop a richer flavor and a thicker skin that helps with storage.
Seasonal variations can also affect your harvesting schedule. For instance, if you experience a particularly wet or dry spell, you may need to adjust your timing accordingly. Potatoes grown in bags tend to drain well, reducing the risk of rot, but it’s still wise to monitor the weather conditions closely and harvest when the soil is dry to prevent damage to your tubers.
Tools and Supplies Needed for Harvesting
Having the right tools and supplies on hand is essential for a successful harvest from your potato grow bags. Here’s a checklist of what you’ll need:
1. Gardening Gloves: Protect your hands from dirt and potential cuts when handling the grow bags and digging for potatoes.
2. Trowel or Hand Fork: A small trowel or hand fork is ideal for loosening the soil around the potatoes without damaging them. Choose a tool with a sharp edge to make the task easier.
3. Bucket or Basket: Once you’ve unearthed your potatoes, you’ll need a container to collect them. A bucket or basket will work well to hold your harvest.
4. Garden Kneeler or Pad: If you’re working on a hard surface or want to save your knees, a garden kneeler can make the process more comfortable.
5. Pruning Shears: Use these to cut away any dead foliage or damaged parts of the plant before harvesting.
6. Watering Can: If your potatoes are particularly dry, a light watering just before harvest can help loosen the soil and make digging easier.
Having these tools ready will not only make the harvesting process smoother but also minimize the risk of damaging your potatoes. Remember that the care you take during the harvest will reflect in the quality of your stored potatoes later on.

Begin by gently brushing off any excess soil from the potatoes. It’s important to handle them with care to avoid bruising. You can do this using a soft brush or cloth. Avoid washing the potatoes with water immediately after harvesting, as moisture can promote rot during storage. Instead, wait until you are ready to use them.
Once cleaned, sort your potatoes by size and quality. Set aside any that are small or damaged, as these will not store well. Larger, undamaged potatoes can be kept for long-term storage, while smaller ones can be used first or for immediate consumption. Remember, the goal is to keep your stored potatoes in the best condition possible, and sorting helps you achieve that.
Identifying and Dealing with Defects
As you sort through your harvested potatoes, you may encounter some common defects. Identifying these issues early can help you prevent spoilage and ensure that your potatoes remain in good condition for as long as possible.
One of the most common defects is scab, which appears as rough patches on the skin. While scab does not affect the taste of the potato, it can make them less visually appealing. If you find scabbed potatoes, simply peel the affected areas before cooking.
Another issue to look out for is greening, which occurs when potatoes are exposed to light. Greening can lead to the formation of solanine, a toxic compound. If you notice any green spots, it’s best to cut them away before cooking. In severe cases, it may be safer to discard the entire potato.
Additionally, check for any signs of rot or soft spots. Potatoes that show signs of decay should be removed from your storage area immediately to prevent them from affecting the rest of your harvest.
Immediate Storage Solutions
After cleaning and sorting, you’ll need to think about immediate storage solutions. If you plan to consume some of your potatoes soon, you can keep them in a cool, dark place, such as a pantry or cupboard. Ensure that the area is well-ventilated to prevent moisture buildup.
For potatoes that you wish to store longer, you can use cardboard boxes or mesh bags, which allow for airflow. Avoid using plastic bags, as they trap moisture and can lead to rot. If you have a cool basement or garage, these can be ideal spots for short-term storage as well.
Remember, the key to preserving your potatoes after harvesting is to keep them in a stable environment that minimizes exposure to light and moisture. This will help extend their shelf life and maintain their quality until you’re ready to use them.
Storing Potatoes for Long-Term Use
Ideal Storage Conditions
To ensure that your harvested potatoes remain fresh and flavorful for an extended period, it’s essential to create the ideal storage conditions. Potatoes thrive in a cool, dark, and humid environment. The optimal temperature for storing potatoes is between 4°C to 10°C (39°F to 50°F). Temperatures higher than this can cause sprouting, while temperatures lower than 4°C can convert the starches into sugars, affecting the taste.
Humidity levels should be around 85% to 90%. If your storage area is too dry, the potatoes may shrivel. Conversely, if it’s too humid, they might rot. A simple way to maintain humidity is to place a damp cloth or sponge in the storage area, but be cautious not to allow direct contact with the potatoes.
Darkness is also crucial. Exposure to light can cause greening, leading to the production of solanine. Store your potatoes in opaque containers or in a dark corner of your pantry or basement. Covering them with a cloth or paper can also help block out light.
How to Store Potatoes from Grow Bags
Storing potatoes harvested from grow bags follows similar principles as traditional storage methods. After cleaning and sorting, place the potatoes in a suitable container. Cardboard boxes, paper bags, or breathable mesh bags are excellent options.
If you’re using a cardboard box, ensure it’s lined with newspaper to absorb any excess moisture. Lay the potatoes in a single layer, if possible, to avoid bruising. If you have multiple layers, separate them with more newspaper or straw to cushion them.
For those who have limited space, consider using a cool closet or a cupboard that isn’t exposed to direct sunlight. If you have a garage or shed, these can also serve as effective storage locations, provided they maintain the ideal temperature and humidity levels.
Regularly check your stored potatoes for any signs of spoilage or defects. Remove any affected potatoes to prevent them from affecting others. By following these practices, you can ensure that your potatoes remain in great condition for several months.
Creative Storage Solutions for New Zealand Homes
In New Zealand, where many homes may have limited space, finding creative storage solutions for your potatoes is essential. Here are a few ideas that can work well in various living situations:
