Hibiscus

Introduction
Hibiscus flowers summons memories of Mai Tais on lanais. Their exotic blooms and glossy leaves add a dramatic accent to temperate gardens. There are many different varieties of hibiscus including perennial, annual, evergreen and deciduous. These instructions are for the Tropical Hibiscus (H. rosa-sinensis).

Step One
Water hibiscus when the soil is dry to the touch. The roots must remain constantly moist, but not wet. Well-drained soil is key.

Step Two
Fertilize hibiscus every 3 weeks with a low nitrogen fertilizer (0-10-10) applied at 1/2 the label recommendation during the spring and summer. Phosphorous and potassium, the last two numbers on the fertilizer label, encourage flower production and root growth.

Step Three
Tip prune hibiscus to keep the plants bushy and full of blooms. Pinch off the tips of branches to encourage multiple growth tips further down the stem.

Step Four
Apply a layer of organic mulch under plants to prevent moisture loss and weed growth.

Step Five
Apply a high nitrogen fertilizer at 1/2 strength when leaf color fades. Yellow leaves indicate a hungry plant or under-watering. The foliage should be a deep glossy green. An application of a balanced slow release fertilizer in the spring will encourage new growth. Foliar feeding is acceptable.

Step Six
Remove faded flowers to keep plants looking tidy. Grooming also discourages insect pests by eliminating their hiding places.

Step Seven
Protect hibiscus from cold weather. Move plants grown in containers to a protected area. Plants grown in the ground should be covered if temperatures are expected to drop below freezing.

Step Eight
Apply an anti-transpirant to protect plants from excessive heat or cold. Cloud Cover is a product which prevents moisture loss through the foliage due to transpiration.

Step Nine
Watch closely for insect pests. White fly, aphid, scale and mealy bug are notorious for dining on hibiscus. Use an insecticidal soap to treat unwanted pests.

 

Thanks ladies
Let me share my small exprience here. It really is very very easy to grow this plant. Either in pots or in fround. Ground I think is best suited in tropical climates. Though my ground here does not freeze in winter these plants do not survive if planted in ground. However they do well in pots. really easy maintenance. they need sun and water and good soil. Amazing the way they flower. Given a choice of plants to buy this will be my number one.

 

I will answer your question with how I would do it.
I usually choose a container one size bigger than current one. But you can choose a bigger container too.
I always use miraclegro potting soil because i get at reasonable price at Sams. And i think its worth it. You can use any potting soil ofcourse. Miracle gro for flowers also comes with fertilizers etc. so no need to add extra.
If you need to bring in your pots indoors during winter keep that in mind while choosing size of container.
You are now good to go. hope this helps.
