When do banana trees produce fruit? What you need to know

Bananas are a delicious, nutritious, and versatile fruit. They are flavorful enough to eat on their own, but mild enough to work well with other flavors. If you’re a fan of this fruit, you might be interested in growing your own banana tree. The important part of having a banana tree, though, is the fruit. If you’re getting impatient waiting on your tree to produce fruit, or if your banana tree isn’t producing as much fruit as you thought it would, then you’re in the right place. We’ll answer all your banana questions so you can be sure you’re getting the most out of your tree.

How long does it take banana trees to mature?

Banana trees are interesting, as they aren’t technically trees. They’re actually herbaceous perennials, which is helpful since we no longer grow bananas from seeds. Instead, the roots of a banana tree send up a sucker, or smaller but still attached, plant. These suckers are then separated from the parent tree and planted elsewhere, to grow into a mature plant on its own.

In total, it takes between nine and 15 months for a banana tree to fully mature. However, banana trees can take longer, depending on the specific variety of banana you’re growing and whether or not all of its needs are being met. Lack of light, incorrect climate, and nutrient deficiencies can slow banana tree maturation significantly.

When are bananas ready for harvest?

Once your banana tree is fully mature, it can begin to produce fruit. The first sign of fruiting is flowers. Banana flowers are fairly large and are an interesting shade of dark purple, so they’re hard to miss. These flowers begin appearing in mid to late spring, although they can also form in early summer if you had a late winter. The first flowers to appear are the female flowers, which are the ones that form fruits. Keep an eye on those flowers and you’ll have a good estimate of when your bananas will be ready to harvest.

Bananas take three to four months to form after the female flowers are pollinated. Typically this means that your bananas will be ready to harvest in late summer or early fall, depending on when your tree began to flower. Growing time can also vary between banana varieties, so be sure you know what kind of banana you’re growing.

Best care practices to ensure it fruits

One of the most important things for banana trees is temperature. Bananas are native to the tropics, where the weather is hot and humid. Cold weather can stunt their growth or even damage them. If you live in a colder region, consider growing a smaller banana variety in a container. Building a wind break and using plenty of mulch can also help.

Banana trees need a lot of light. Cold can kill a banana plant, but inadequate light slows its growing speed and results in a much longer wait time for fruit. A grow light can help with indoor banana trees, but the easiest solution for outdoor trees is to choose a sunny planting location.

Make sure the soil your banana tree is in is rich, loamy, and well-draining. Although banana trees need a lot of water, it’s still possible to overwater them if they’re in poor-draining soil. The soil should also be nutritionally dense. Adding compost or banana-specific fertilizer fairly regularly can help you ensure a good harvest.

How to harvest bananas, and what happens afterwards?

Depending on the specific variety of banana you’re growing, size may or may not be a good indicator of harvest time. Instead, look for a hand, or group, of bananas that have stopped getting thicker. The upper layer of bananas in the hand should be changing to a lighter shade of green. Remember that bananas will ripen after harvest, and green bananas are still edible, so harvesting them a little too early will result in smaller, but not inedible, fruit.

Using a sharp, clean knife or pair of garden shears, cut the entire hand off of the tree. Leave some of the stem at the top of the hand for an easier time carrying it. Depending on the size of your tree, you may need to use a ladder to harvest the bananas. Be careful when securing and climbing the ladder. It’s easier if you have someone to stand by that can hold the bananas while you climb down.

After harvesting the bananas, your tree may appear to die. This is because each stem of the banana plant only fruits once. However, the plant itself will remain alive. Any suckers your tree has put out will grow and fruit as well. The stem that just finished fruiting can be cut down, both to give the next stem room to grow and to help your plant conserve energy.

With all this in mind, you’re ready to help your banana tree produce delicious fruit for your smoothies or snacks. Pay close attention to the needs of your plant, and keep an eye out for any suckers that form near your original plant. With patience and proper care, you’ll have plenty of fresh bananas before you know it!

One part of the country that many gardeners envy is climate zone 10, a warm sanctuary for a variety of plants, thanks to its very long growing seasons and mild winters. Made up of the southernmost parts of the country, this region has a climate that's ideal for multiple rounds of harvests. While it has specific challenges with blisteringly hot summers, it’s an overall welcoming environment for plant life. Below, we’ve rounded up everything you need to know about zone 10 and all the plants that you can grow in it.

Where is climate zone 10?
Before we get into the specifics of climate zone 10, let’s talk about the USDA Plant Hardiness Zone Map. When shopping for plants, you may see labels indicating a zone range — that basically tells you where the plant will be hardy for more than just one growing season. Essentially, the United States Department of Agriculture has divided the country into 13 regions, or climate zones, based on annual minimum temperature ranges. Zone 1 faces the coldest winters, while zone 13 usually has the warmest ones. Bearing this in mind, inhabitants of zone 10 will often experience warmer winters.

Potatoes are a delicious, nutritious, and versatile food. They’re easy to grow and fun to eat, but what exactly are they? As gardeners, we use the phrase "fruits and vegetables," but what is the key difference between these two categories? More importantly, which category do potatoes fall into, and why does it even matter? If these questions have ever crossed your mind, then you’re in luck! In this handy guide, we’ll explain what makes a fruit a fruit, a vegetable a vegetable, and a potato a potato.

What is a fruit?
Fruits are a specific part of a plant that's formed to help protect and spread the seeds of the plant. Not all plants produce fruit. Some flowers, for example, form seed heads that help to disperse the seeds. Sunflowers and dandelions are good examples of this. Not all fruits are edible, either. There are plenty of poisonous berries, including yew and holly, which are eaten by birds but are toxic to humans.

Many gardeners start seeds indoors during the last weeks of winter or early spring to get a head start on the growing season. When it's too cold to plant anything outside, you can start seeds indoors and transplant them in the ground once the weather warms up.

So what can you use for your seeds without spending a fortune on seed-starting trays? Plastic cups left over from parties or camping trips are ideal. Recycling these cups provides the perfect temporary (or even permanent) homes for your plants, and you'll get the cutest container garden in the process!
