About Lilac

Common lilac is a highly fragrant, spring-flowering shrub or small tree. The pungently sweet fragrance is delightful but can be overpowering to some asthmatics. Most plants are grafted so suckers should be removed from rootstock to maintain the appearance and prevent unwanted spread.

How to fertilize Lilac

Nutrient, fertilizer, and repotting needs for Lilac: repot after 2X growth

Most potting soils come with ample nutrients which plants use to produce new growth.

By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.

To replenish this plant's nutrients, repot your Lilac after it doubles in size or once a year—whichever comes first.

🌱 Propagation

Lilac can be propagated by the stem method. To propagate:

  • Make a cut just above the node. The node is the break in the stem where the leaf emerges.
  • To get the cutting to root, you can either:
    • Place the cutting in water until roots emerge and are ~2” long and then transplant into well-draining soil, or
    • Place the cutting directly into well-draining soil and water when dry.

🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
