Best Varieties, Planting, Care, Problems and Harvest

Kumkum are small tasty fruits that look like mini oranges. The flesh is slightly sour, while the skin is sweet, giving them a unique taste. Growing kumacuts have become popular because they are easy to grow and are quite beautiful.

In spring, the Kumkum tree is covered in beautiful white flowers with a bold citrus scent. They make stunning decorative joints in the garden or in containers, indoors or out.

If you want to try growing these lovely, grape-sized citrus fruits, we’ll guide you, so let’s start.

Variations of Kumawat

Kumaquets (Citrus japonica) Are native to East Asia. The fruit may be round or oblique.


It is a popular variety with a rectangular rather than round fruit. This can be some many seeds for my taste, with two to five seeds in each fruit. The taste, however, is outstanding.


‘Nagami,’ slightly larger than ‘Mewa’, is a great pick for a home garden. It has sweet pulp and juice compared to other kumkum and is often seedless.

It is a semi-dwarf variety, so it is more compact than some others.

A good variety for containers, ‘Marumi’ will give lots of fruit under the right conditions. If you are growing it in a pot, then every two seasons you will need to remove the tree from the pot to slightly rear the roots.

Mild variety

If you can catch ‘Centennial Variated’, this is my top pick for you. A ‘Nagami’ must be a cross between kumkum and a mandarin, a very sweet variety that once lived for months on a ripe tree.

Fruits can vary in color, until they ripen to orange.

USDA Hardness Zone 8 may have ‘Centennial Variated’ increases, and I would personally give it a try.

How to apply Kumkum

Kumquats are easy to grow, so they are a good tree for both beginners and experienced gardeners. They are self-pollinating, so you only need to plant one.

Kumkuts grow well in the growing USDA from USDA 9 to 10.

If you live somewhere that cools down, you can always grow it in a container and turn it around the sun, and bring it inside in the winter.

Kumkum requires full sun as long as you live in a scorched area, they do not do well in shaded areas. They will then tolerate partial shade in the hottest part of the day.

The loam, well-draining soil, which can remain moist, is best for Kunkum. Aim for a pH of 5.5 to 6.5.

Plants in spring when there are frequent sunny days. Kumkum is hardy, and once the sun starts shining in spring, you can start planting. Do not mumble waiting for perfect planting conditions.

Container planting

If you follow some basic principles then kumkum do well in the container.

Like most citrus, they do not like to be tied in pots to the root. To avoid this, use the largest container you can.

Kumquats do not like disgusting feet, so make sure you use a container that drains well. Carefully cut or drill additional drainage holes if necessary.

Kumkum planting by seed

Planting by seed is not the best route. This is a laborious process and can result in weakening or thinning of the tree. Still, it can be a fun project to see if you can build a new tree.

Choose a healthy kumkum fruit in the fall. To separate the seeds from the meat, place the peeled kumkum in a glass of water. Within a couple of days, the fruit will be soft.

Mash the pulp gently and pour in clean water. Seeds floating on top are viable, so save them. Place them on a paper towel to dry for a week.

Place the seeds in moist peat moss and put them in a plastic bag. Keep it in the fridge until spring. Ensure that the peat moss remains moist. If it starts to dry then spray it to get wet.

In the spring, place the seeds on top of the raising mixture and cover them lightly. Place the entire container in a plastic bag, and keep it moist.

Place the container on the side of a window until germination.


Plant in full sunlight in loam, well drained soil. These plants cannot handle the soil.

Ensure that the soil remains moist for the first few years. If it is planted in a windy area then stop the tree.

If you plant your kumkumas as a hedge, keep the trees five feet apart. If you plant trees in an orchard, keep them about 12 feet apart. Most trees grow up to 15 feet in height.

Care of gum trees

Once you have kumkum in the field, it is time to make sure that they remain healthy and happy. Here’s how to do it.


Do not apply compost for the first three months after planting the tree. After that, fertilize once every two months during the growing season.

I use liquid fertilizer containing fish or seaweed. You can also use a granulated citrus fertilizer.

If you use dry fertilizer, make sure you water before fertilizing and then directly after it. Kumkum roots can be sensitive to fertilizer.


Keep the soil moist but not wet. You can allow the surface to dry, but once the soil has dried, water an inch deep, thoroughly. Kumquats are susceptible to root rot, so do not put in water.

If your kumkum are in the container, give them a deep water when the top inches of soil have dried. Water until it comes out from under the pot.

sorting out

I like the kumquats to be perfectly sized as I place them in front of a deck as a hedge.

If you prefer to shape, do so during fruiting and dormant seasons for the next season of flowering.

Otherwise, remove any crossing branches to increase air circulation. Remove any diseased or dead branches.

Companion planting for kumkum

Kumkum grows well when planted with other citrus:

Also plant with:

  • Borage
  • Nastasyam
  • Anise
  • Lemon balm
  • Tanzi

Common Problems and Solutions for Increased Coatage

With most citrus trees, there are some problems that you may need to watch for growing kumkum.

Practice good garden hygiene and keep the soil healthy and digestible. As soon as you notice something wrong, address any issues with pests and disease.

Flour bug

Milebugs are sap-sucking pests that often live on the underside of leaves, making them difficult to target with sprays.

They emit honeydew, which in turn attracts ants and often contributes to soot mold.

To control milebugs, clear all debris like tall grass and weeds, which they can overwinter. At the end of the season, remove the fallen fruits from the ground.

To kill these bugs, dilute isopropyl alcohol from 1 to 5 and spray the plants.


Another sap-sucking insect, aphids cause a lot of damage when they become very large in number.

They also expel honey dew, which can attract soot mold.

I use neem oil and organic pyrethrum for a bedbug and long term effect combination. We have a guide to help you identify and manage these bugs.

root rot

Root rot in citrus is often the result of roots sitting in water for too long. Roots die due to lack of oxygen.

Roots can also rot due to fungus in the soil.

Prevention is better than cure for rot, so make sure the soil is well drained and not in water.

Sooty cam

As the name suggests, if you have this disease, your plant looks like it is covered in black soot.

Treat the source of mold. Look for milebugs, aphids, or any other insect that emits honeydew.

Treat the problem pest, and you will reach the top of the soot. Once the pest problem is resolved, you can wipe the plants with a wet cloth. It is just superficial.

Harvesting and Harvesting

When they are of a deep orange color, the kumukuts are ready for harvesting and the skin is slightly soft to the touch.

Eat or use the whole thing in fruit salad, stodge or casserole, and jam. Candid Kumket is my children’s favorite.

You can store them in the refrigerator for several weeks.
