In summer, the flowers become small fruits that exactly look like apples. Colors vary depending on the species, but they are mostly in the shades of yellow, pink, green, red, and orange.
Come winter, the leaves begin to fall off and what remains is the fruit on bare stems and branches. However, the tree still looks stunning even without the leaves.

How to Grow Crab Apples
You may have already seen some crab apples in orchards, but these are now common in many households. Originally, they are grown in regions in Asia, Europe, and North America with warm and cool climate.
Crab apples can be grown in gardens, backyards, and any location with cold and warm weather conditions. Whether it’s a place with cold winter or warm summer, these trees can thrive in these areas.
The ideal soil condition for crabapple trees is moderately fertile and well-draining. You can add an organic compost to your soil so that your crab apple will get the essential nutrients when you plant them.
The organic compost also improves the draining ability of the soil, especially when mixed with some sand. To keep it fertile, top-dress the soil with organic mulch to ensure healthy growth for your crab apple.
Adding nutrient-dense compost to the soil helps provide nutrients to your plants along with regular watering. A sufficient supply of nutrients to your tree is most important during flowering and fruiting stages.
Crabapple trees grow well in full sun. If you’re planning to add this to your garden or orchard, make sure to plant the tree where it’s exposed to sunlight. Without adequate sunlight, your crabapple will not bear abundant flowers.
Moreover, crab apple trees in shade will produce less fruits while the branches don’t grow in well-rounded form. Before you plant your crab apple, find an area where direct sunlight is available throughout the day.
While some varieties can thrive in partially shaded area, they still require full sun for some hours per day. If not, they will stretch their branches out in order to get some sunlight. The result will be unsightly since the branches tend to grow unequally.
A young crab apple tree needs thorough and regular watering. The goal is to maintain the moisture of the soil in order to provide steady supply of nutrients to the roots. However, you need to use well-draining soil to prevent root rot.
You can water your crabapple once or twice every week. However, check the soil’s condition particularly the moisture level before giving your tree a drink. Stick to a regular watering schedule for best results.
Once crab apple trees are deep-rooted, they become drought tolerant. That means you don’t need to regularly water them. Mature trees satisfy their moisture needs through rain.
Crab apple trees like cold winters and warm summers. However, hot climates impede their growth which results to less abundant fruits and flowers. It’s warm enough in my area during summer and cold enough during winter, perfect for my crab apples.
Typically, these fruit-bearing trees thrive well in climates of England, Canada, United States, and some regions in Europe. Throughout the seasons, these trees have a colorful transformations, from vibrant green leaves to red orange foliage during winter and fall.
Since you are advised to add organic compost to feed your crabapple tree with all the essential nutrients, fertilizer might not be necessary. Top-dressing your tree with organic mulch every year is enough to provide nutrients for your crabapple.
However, if you want to fertilize your crab apple trees, you can do it before the grow season begins, which is in the spring. On the other hand, you can also add fertilizer to your trees in the fall when the soil temperature remains below freezing point.
In my case, I used loamy soil so I fertilize my crab apples with up to 5lbs nitrogen for every 1,000sq ft. This is also done annually to make sure the trees are supplied with adequate nutrients.
Unlike other decorative trees in the garden, crab apple trees are so easy to care and maintain. When it comes to pruning, they don’t need any special kind of trimming. If you see some suckers, you simply remove them by cutting away damaged or dead branches.
I love to trim my crab apples in the backyard to maintain their appeal. Sometimes, I encounter dead branches during fall and remove them to avoid the unsightly form.

Boil the crab apples and then lower the heat to simmer the fruits. Stir it slowly until the crab apples become mushy. Allow the jelly to cool before you put it into small jars or jelly bags.

Mix the juice with sugar and boil it while stirring in order to dissolve the sugar. The mixture must be boiled quickly to a setting point. To know if it has reached the setting point, drop some amount onto a plate. There should be a wrinkle on top when it’s cool.
Pour the crab apple jelly into sterile containers and seal them immediately. You can serve your jelly with meat or any food that you want to partner it with. I’ve made crabapple jelly for my kids and they love the sweetness and apple flavor.
