Problems With Blue Lake Pole Beans

If you’ve ever grown pole beans, chances are that you have encountered the Blue Lake variety. This is a popular type of bean among gardeners because it produces an abundance of large pods and are easy to grow in many climates. However, there can be some issues with this particular strain including poor yields, fungal diseases, and bacterial blight. In this blog post, we’ll explore these problems in greater detail so that you can troubleshoot them if they arise while growing your Blue Lake pole beans!

What Are Blue Lake Pole Beans?

Blue Lake Pole Beans are a variety of green beans widely used for cooking. They have been around since the mid-1900s and are generally considered to be one of the best tasting varieties of pole beans. The beans grow in length and are typically harvested when they reach about five inches long. While there are many benefits to eating Blue Lake Pole Beans, there can also be some drawbacks that should be noted before using them. [1]

Problems With Blue Lake Pole Beans

Yellow Leaves

Yellow leaves are a common issue that occurs with Blue Lake pole beans. Yellow leaves can be caused by a lack of nitrogen in the soil or overwatering, which can lead to root rot. To avoid this problem, provide your plants with plenty of nitrogen-rich fertilizer and water them deeply but infrequently.

Yellow Leaves

Shriveled Leaves

Shriveled leaves are another-issue frequently encountered with Blue Lake pole beans. This is often caused by drought or not enough water. To prevent this issue, make sure to keep the soil evenly moist and provide your plants with one inch of water per week.

Malformed Bean Leaves

Another issue with Blue Lake pole beans is malformed bean leaves. This can be caused by too much nitrogen or a fungal disease. To avoid this problem, keep your garden free of weeds and provide the correct amount of fertilizer to the plants. If you notice any signs of a fungal infection, use an appropriate fungicide to treat it quickly.

Green Leaves Are Drying Up

One of the most common problems many gardeners experience with Blue Lake Pole Beans is dry, wilting foliage. This can be caused by a variety of factors such as too much sun exposure, lack of water or nutrients in the soil, or poor drainage. To keep your beans from drying out, it’s crucial to provide them with enough water and fertilizer during their growing season. 

Additionally, make sure you choose an area with enough sunlight but not too much; if the leaves become scorched from too much sun during peak hours of the day, the plant will quickly wilt and die.

Irregular Holes in The Leaves

Another common problem with Blue Lake Pole Beans is irregular holes in the leaves. This is usually caused by bean weevils, small insects that feed on the foliage of your plant. If left unchecked, these pests can cause serious damage to your crops. To prevent this from happening, keep a regular eye out for them and take action when necessary. Control measures such as insecticidal sprays or organic products can be used to protect your from bean weevils. [2]

Irregular Holes in The Leaves

Unusual Leaf Spots

Another potential issue with Blue Lake Pole Beans is the appearance of unusual leaf spots on the foliage which could indicate disease or fungus spreading throughout the plant. To remedy this situation, you should first determine what type of disease or fungus it is and then take appropriate action. Depending on the type of fungus or disease, you may need to treat it with a fungicide or other pesticide to prevent further damage from spreading. Additionally, if your bean plants are overwatered and not given enough sunlight, they are more susceptible to these problems, so be sure to properly care for them as well.

Overall, Blue Lake Pole Beans can be a great addition to any garden, but they require special attention in order to remain healthy and productive. With regular maintenance such as proper watering and fertilization along with protection from pests and diseases, your beans should stay strong and produce delicious crops for years to come!

Causes of Bean Problems in Blue Lake Pole Beans

Blue Lake pole beans are prone to several problems that can diminish their yield and overall quality. Diagnosing the cause of these issues is often difficult, but understanding the potential causes can help gardeners troubleshoot common bean plant problems.

The most common issue affecting Blue Lake pole beans is poor pollination. Low temperatures and insufficient humidity prevent bees from visiting flowers, which can lead to stunted seed development or no seeds at all. To remedy this problem, gardeners should ensure that flowering occurs during the warmest part of the day when bees are likely to be active. Additionally, planting bean varieties with a longer blooming period may help increase pollination rates.

Fungal diseases such as anthracnose and rust can also threaten a bean crop. These diseases thrive in warm, wet conditions and cause lesions on the leaves that can spread to the pods. To prevent these issues from occurring, gardeners should ensure that their plants have adequate air circulation and are not overcrowded or over-watered. If signs of fungal disease appear, fungicides may be necessary to treat the infestation and restore plant health.

Finally, pest infestations can also lead to poor bean yields. Insects like aphids, beetles, mites, and nematodes feed on the leaves and pods of pole beans. In addition to damaging plants directly, pests can transmit viruses among bean varieties which can stunt growth or kill seedlings. To reduce the risk of pest infestation, gardeners should rotate crops, monitor plants for signs of pests, and use organic insecticides to control existing populations.

Overall, Blue Lake pole beans can face several issues that diminish their yield and quality. By understanding the potential causes of these problems—pollination difficulties, fungal diseases, and pests—gardeners can take proactive steps to ensure healthy bean plants. With proper management strategies in place, a successful harvest is more likely to be achieved. [3]

Prevention of Green Beans Problems

Proper care and maintenance of blue lake pole beans can help prevent some common problems. For instance, uneven watering can contribute to issues such as blossom end rot and sunscald in green beans. To ensure consistent moisture levels, water your plants regularly and check the soil for dryness or wetness before irrigating. Mulching around the base of the bean plant is also an effective way to keep the soil moist while discouraging weeds that may compete with beans for resources.

Finally, proper support for your bean plants is essential. Staking or trellising will help to provide better air circulation, discourage dampness around the base of plants, and reduce pest problems such as slugs or snails. Pruning off any yellowed or diseased foliage can also help prevent disease spread throughout your crop. With a little extra care and attention, you can ensure a successful season of blue lake pole beans!

Do Blue Lake Beans Need Fertilizer?

Blue Lake pole beans typically benefit from regular fertilizing, especially when grown in poor soil or after they have produced for a few years. Ammonium sulfate is the preferred fertilizer option as it provides more nitrogen than other materials. Fertilize at planting and then every 4-6 weeks throughout the growing season, using 1 tablespoon per 10 feet of row. Too much nitrogen can cause lush foliage but reduced yields, so be sure to follow the directions on your fertilizer package to avoid overfeeding your plants.

For organic gardeners, compost tea or manure tea are great options for fertilizing Blue Lake pole beans. Apply these teas every 2-3 weeks during the growing season according to the manufacturer’s instructions. Adding supplemental phosphorus may also be helpful if your soil test indicates it is lacking in this essential nutrient. You can purchase organic phosphorus sources such as bone meal or rock phosphate at most garden centers. Apply 1 cup of phosphorus per 10 feet of row and work into the soil before planting.

Blue Lake pole beans usually don’t require additional fertilizer after they have been established, but adding a few cups of compost or aged manure once a year will help to maintain fertility levels in the soil. Overall, with proper fertilizing and regular watering, Blue Lake pole beans should be able to thrive and produce abundant yields for many growing seasons. [6]
