Jade plant (​Crassula ovata​, formerly ​C. argentea​) is a super-easy plant to grow, especially for the forgetful gardener who prefers low-maintenance plants. Although jade grows as a perennial in the warm climates of U.S. Department of Agriculture plant hardiness zones 11 and 12, it's a popular houseplant in all zones. Clemson Cooperative Extension notes two of the main reasons that it excels as a houseplant: It thrives in containers and prospers in warm, dry interior environments, conditions that cause many houseplants to struggle.

As a succulent plant, jade has only a moderate demand for water during the growing season and needs even less water during fall and winter. And, although you should let the soil dry slightly between waterings, you should avoid fertilizing plants when the soil is dry; otherwise, the fertilizer can burn the roots.

How to Fertilize Jade Plant

As part of its low-maintenance regimen, jade plant has a low fertilization requirement. You'll need to apply a water-soluble houseplant fertilizer only every three months. To prevent root injury, make sure the soil or potting mix is moist before applying fertilizer. And always follow all label recommendations for mixing the fertilizer in water.

Due to the plant's minimal need for fertilizer, the choice of growing mix is important. Unlike other types of plants that flourish in organically rich, fertile potting mix, jade plant grows best when planted in a different medium.

Use a potting mix that's blended for succulents or cacti. These mixes contain ingredients that promote good drainage, including sand, pumice and perlite. Avoid those that already contain fertilizer, because they may provide too much nutrition for a jade plant. The continual and slow release of nutrients, instead of a single fertilizer application every three months, may eventually burn plants.

Fertilizing a Repotted Jade Plant

Another of jade plant's desirable easy-care traits is that it will continue to grow for years while root-bound. Eventually, however, you'll need to repot your jade plant. As it ages, you may want to move it into a heavier pot because its top growth has a tendency to cause a lightweight pot to tip over. Or you may just want to repot your jade plant into a more ornamental container instead of the plastic utilitarian pot it came in.

Don't repot your jade plant until you see new foliage emerging, which signals onset of a growth period. Water the plant before removing it from its former container and let the potting mix in the new container dry slightly after you repot it. A newly repotted jade needs to acclimate itself to its new surroundings before receiving fertilizer, so wait for four months after your jade plant has been repotted before applying fertilizer for the first time.

Other Jade Plant Cultural Requirements

Fertilizer is only one component of jade plant care. To keep your plant healthy, place it where it will receive bright light. A little direct sun, preferably in the mornings, is OK. But avoid giving it too much direct sun, particularly if you have one of the variegated cultivars such as ​Crassula ovata​ 'Tricolor' (green, cream and pink leaves) or ​C. ovata​ 'Variegata' (green and cream leaves).

With no significant insect or disease problems, the primary problem with growing jade plants is rotting of roots and stems. This problem is caused by fungal pathogens that result from overwatering, or growing plants on a potting medium that doesn't drain well.
