Fruitless mulberries are not a common sight in the garden. They are usually found in orchards and other places where they don’t need to be seen. You may have noticed fruitless mulberries when you were looking at your apples last year, but now you’re wondering why there’s no fruit on them yet!
The reason for this is because most mulberries are self-fertile. That means they produce their own seeds without any help from the sun or rain. There are several reasons why fruitless mulberries aren’t producing fruits right now.
Here are some of the main ones:
1) Mulberry leaves can be infected with disease (see above).
If you see white spots on your leaves, it’s probably due to leaf spot fungus (also called powdery mildew). These fungi grow on the leaves and cause them to turn yellowish brown. The fungus grows fast and spreads quickly so it can kill the plant within just a few days.
2) Mulberry flowers are susceptible to insect attack.
Some insects like aphids will eat the flower buds if they get too close. Other pests include caterpillars, spider mites, thrips, mealybugs, scale bugs and many others. It’s hard to protect your mulberries from these predators since they’re so small.
If you see them on your mulberry tree, you can try natural and organic pest control by watering your plant with soapy water (put a little dish soap in the water). You can also release ladybugs and other predator insects which eat the bad bugs.
3) Your mulberry tree could simply be diseased or lacking nutrients.
These problems are harder to spot than insects, but just as deadly. To counter these problems, you can water your plant with organic fertilizer. You should also water it with compost tea since it has lots of nutrients and beneficial microbes which will give your tree a healthy glow.
Whatever the reason, it seems like your mulberries just aren’t producing fruits right now. This is a real shame since mulberries are delicious when ripe! In fact, you might find yourself tempted to pick one and try it…
don’t do it! Mulberries that have fallen to the ground are full of worms and maggots which will crawl all over you if you try to eat them.
Leave the mulberries alone until next year, when they should be ripe and delicious! In the meantime, you can start growing another type of mulberry tree. Make sure you pick one that’s self-fertile so you don’t have to go through this hassle again!
