Christmas Cactus, Avocado, and Shamrock Care: A Complete Guide

Christmas Cactus (Schlumbergera)

• Branching: Pinch tips to encourage branching; no set segment rule.
• Water: After bloom, keep drier (near wilt). Rest of year: water when top ¼ soil dry.
• Watering method: Top watering is fine; discard excess.
• Fertilizer: Any 3-1-2 ratio at half-strength monthly during growth. No "succulent fertilizer" needed.
• Bloom trigger: Cool fall temps (35°F nights) + short days. Summer outdoors in shade, then leave out until near frost. Buds set in cool/dark. Bring in, resume water, enjoy.

Avocado from Pit

• Grows tall, single stem. Pinching rarely forces branching.
• Needs full sun indoors. Water when top inch dry.
• Leaf drop = low light or watering issues.
• Prune to control height. It's a novelty, not a great houseplant.

Shamrock (Oxalis regnellii)

• Don't repot. Keep in nursery pot inside decorative cachepot.
• Pests: Spider mites indoors. Outdoors = local insects.
• Dormancy (critical): Sept: stop fertilizing, reduce water. Oct: stop water, move to cool/dark. Feb: resume water/light/fertilizer.
• Propagation: Separate corms in Feb.

Your south window (sun in winter, shade in summer) suits all three.
