Planting & Care

Where to Plant

  • Sunlight: This catmint thrives in full sun, needing at least 6 hours of direct light each day for the sturdiest stems and best flowering. While it can handle a little shade, too much will cause the plant to become leggy and flop over, significantly reducing bloom production.
  • Soil: It prefers average, well-drained soil and is quite tolerant of rocky or sandy conditions. The most important factor is drainage; if you have heavy clay, amend it with organic matter or plant in a raised bed, as soggy roots will quickly kill this plant.

Watering Requirements

Water consistently during the first season to help the root system establish, checking that the top inch of soil dries out between waterings. Once established, SylvesterBlue™ is drought tolerant, though an occasional deep drink during prolonged dry spells will keep the foliage looking fresh and support better reblooming.

Pruning Tips

Shear the plant back by about half after the first flush of flowers fades in early summer. This technique acts like a reset button, tidying up the mound and encouraging a fresh flush of foliage and a second round of blooms later in the season.

Fertilizer Needs

Apply a general-purpose, slow-release garden fertilizer once in early spring as new growth begins to emerge. Avoid heavy fertilization, particularly with high-nitrogen products, as this promotes weak, floppy growth rather than the compact habit and flower power you want.

#ProPlantTips for Care:

Catmint is a full-sun herbal plant and does best in very well-drained soil, but isn’t fussy about soil type. Provide regular moisture for young plants while first establishing, but after these are xeric and low-moisture need plants. For best results, provide supplemental moisture during extended periods of drought and in extreme heat and a 3-4 inch layer of arborist mulch chips for moisture retention. Deadhead for more blooms and prune mound back to a few inches in late fall once it has died back from frost.

  • Full Sun
  • Almost Any Well-Drained Soil
  • Moderate to Low Moisture Once Established
  • Deadhead for Rebloom & Prune Late Fall After Frost
  • Deer & Pest Resistant
