What Causes Mushy Strawberries?
Whether growing or buying - avoid mushy strawberries
Strawberries are among the fruits most often grown in home gardens. Providing general care like full sun, well-drained soil, organic matter and a weekly inch of water produces the greatest and healthiest yield. Preventive care should also be practiced. It's important to know what to do but also what not to. Additionally, when you shop for strawberries, look carefully and know the signs of a diseased fruit.
If you grow your own, be careful where you plant
Verticillium wilt is a serious strawberry disease, which occurs if strawberries are planted near other plants known to often harbor the disease. This include eggplants, potatoes, tomatoes and peppers.
The most common and serious form of fruit rot
Strawberry gray mold is caused by the Botrytis cinerea fungus and is the most serious and common form of strawberry fruit rot. The disease can reduce your yield by 50 percent or more. The mold flourishes during long periods of rain and overcast conditions during bloom time and harvest. Strawberry infections generally appear on the fruit as a light-brown patch that quickly enlarges and decays. With moist conditions, the fluffy fungal growth is visible on the infected tissue. The gray-brown color gives the disease its name.
Prevention Tips: Better air movement and improving sunlight penetration will will help reduce the possibility of gray mold. This is readily achieved by thinning out the strawberry beds. During the winter, dead leaves and debris should be removed from the beds to reduce a possible source of fungus.
Why you should not use black plastic to avoid weeding
Anthracnose fruit rot (Colletotrichum acutatum) is a destructive disease affecting California cultivars if they are grown on black plastic. The practice, most destructive during warm weather, can cause between 60 to 75 percent of fruit loss. Anthracnose fruit rot appears on green strawberries and ranges in appearance from soft to a firm brown to black spots. On ripe fruit, the disease appears as purple spots enlarging quickly until the whole strawberry rots. Pink lesions on the surface can turn to masses of orange spores. Spores are dispersed to other fruit in the form of splashing water. You may think this is a convenient way to prevent weeds but it should be entirely avoided.
Be careful when you buy commercially grown strawberries
Leak (Rhizopus nigricans) was once a common and destructive form of fruit rot occurring after harvest. Commercial strawberries now have refrigeration during shipping which helps prevent the problem. Characteristics of the fruit rot show no changes at first with the fruit remaining the same color. Later, it turns light brown and the strawberry becomes soft and watery, then collapses with juice running out, which is why the disease is called Leak. Rotted strawberries, especially those that are packaged, will soon become covered with a white cottony fungus and black spore-producing structures. The fungus will only enter ripe fruit through a wound. I've seen this white cottony fungus when I shopped for strawberries. Don't think it's enough to bring them home and wash them.
Avoid eating those tough strawberries
Leather Rot (Phytophthora cactorum) happens occasionally on both green fruit and ripe fruit. Rotted strawberries will be light brown in the middle and have shades of purple on the edges. Late stages of decay will make the fruit leathery and tough. I've bitten into many a tough strawberry. But sometimes, like in this case, you cannot tell the purchased fruit is diseased until you take a bite.
But when all goes well, there is nothing like a perfect strawberry!
