How to Grow Bishop's Castle Rose Successfully in Thailand

Factor	Ideal Level
Light	At least 6 hours of direct sun daily, morning sun is best
Water	Water when the top 2-3 cm of soil is dry; in hot season usually once each morning
Pot	At least 12-14 inches in diameter with drainage holes
Soil	Loose, well-draining, mixed with composted manure
Fertilizer	Balanced or bloom-boosting formula every 3-4 weeks during flowering

Light and Water

He loves morning sun. If your balcony gets harsh afternoon sun, a light shade net helps. Water at the base, not over the leaves, because leaves that stay wet overnight are the start of black spot. Poke a finger into the soil; if it is still damp, hold off.

Pruning and Feeding

When a flower fades, cut just above a true leaf with 5 leaflets. He will branch out and rebloom sooner. Remove dry and crossing stems so air can pass through.

Common Rose Problems and Fixes

Black spots on leaves: remove affected leaves, clear fallen leaves from the pot, avoid wetting foliage, and use a fungicide according to the label
Yellowing and leaf drop: check first whether the soil is too wet, since root rot is the most common cause
Thrips and aphids: spray off with strong water or use an insecticide as labeled
No flowers: almost always not enough sun

For homes with dogs or cats, roses are not seriously toxic, but the thorns are sharp and fertilizers or chemicals can be harmful. Keep the pot out of reach.

Who It Suits and Who It Doesn't

If your balcony gets at least half a day of morning sun, this rose is a great fit. For a condo room with no direct sun at all, I would not force it, because he will decline quickly. Choose a low-light indoor plant instead.
