Kumquat

Growing

Because kumquats do not continue to ripen once picked, harvest them when they reach full maturity. To prevent problems like brown rot, which can overwinter on mummified fruit, clear away any old, shriveled fruit left hanging on the branches or lying on the ground beneath the tree. Keeping the area clean maintains tree health.

Regular pruning and training make it easier to manage the size of your tree. For a larger variety, maintain a manageable height by pruning annually and tying down upright limbs. With limited space, train the branches along a trellis (a technique known as espalier) to keep the tree compact. If you are planting in a container or a site prone to heavy rain, use well-drained soil; waterlogged soil can lead to root rot.

Store the fruit in the fridge to maintain freshness, but keep it unwashed until you are ready to eat it. Kumquats can also be preserved through drying or pickling.
