• Size – Choose at least a 12-16 inch diameter pot. May night salvias reach 18-24 inches tall and wide. Size up for larger plants.

• Saucer – Use a matching saucer or drip tray to protect surfaces from excess water drainage.

Providing Perfect Soil for Potted May Night Salvias

These salvias thrive in loose, well-draining soil. Follow these tips to prepare ideal potting mix:

• Use a quality container planting mix, not dense garden soil.

• Incorporate perlite or pebbles to improve drainage.

• Check pH is slightly acidic, around 6.0-6.5. May night salvias like acidic conditions.

• Mix in controlled-release fertilizer to feed plants for several months.

• Fill pots nearly to the top to support flower spikes later on.

Positioning Pots for Optimal Sun Exposure

One key to prolific flowering is placing pots where may night salvias get full sun. Follow these sunlight guidelines:

• Position containers in south or west-facing spots for at least 6 hours of direct sun daily.

• East-facing locations work if plants get sun most of the morning.

• Add supplemental lighting if the area gets less than 5 hours of sunlight per day.

• Rotate pots regularly so all sides get equal light exposure.

Mastering Watering for Potted May Night Salvias

These salvias should be watered consistently without overwatering. Follow these tips:

• Pour water directly into pots, not just saucers, to saturate the whole root zone.

• Empty saucers after 15 minutes so pots aren’t left in standing water.

Applying Light Fertilizer for Abundant Blooms

While may night salvias don’t need heavy feeding, fertilizer enhances flowering and growth.

• Use a balanced liquid fertilizer every 2-3 weeks during the growing season.

• Only fertilize potted plants, not in-ground plantings amended with compost.

Encouraging Fuller Growth Through Regular Pruning

Pruning encourages bushier may night salvia plants and more flowers.

• In winter, protect roots from freezing by mulching around pots. Move to a sheltered spot if temperatures drop below freezing.

• In spring, remove mulch and resume regular watering and fertilizing as plants come out of dormancy.

Handling Repotting to Keep Plants Healthy

Repotting every 2-3 years into larger containers rejuvenates rootbound salvias.

• Look for signs it’s time like roots protruding from drainage holes or poor growth.

• Ideal time to repot is early spring before growing season starts.

• Choose a container 1-2 inches wider than the current pot.

Continuing Care of May Night Salvias Indoors

You can also grow may night salvias in pots as houseplants during the winter months.

• Gradually move pots inside in early fall before first frost to avoid transplant shock.

• Place in a sunny south-facing window where plants get at least 4 hours of direct sun daily.

• Water whenever the top 1-2 inches of soil become dry and mist leaves occasionally.

• Rotate pots regularly and prune as needed to encourage compact, bushy growth.
