Simply check it out every hour or so and observe whether is sunny or shady. It’s also important to keep in mind that you might have different types of shade on different parts of your balcony.
If you have 3 to 6 hours means that your balcony is suitable for partial sun and partial shade plants. In case the balcony plants receives a continuous stream of light filtered through the branches or a nearby building, it’s suitable for plants that need filtered or dappled light.
If you have less than 3 hours of sun, your balcony is suitable for plants that need full shade.

Soil, Fertilizer and Pots
After you have chosen your plants, you will need to pick appropriate soils, fertilizers and pots. It’s important to read plant information when you purchase your plants to see all the care requirements when it comes to soil and other things.
When considering shade-loving plants, remember that most of them were originally found growing on forest floors. The soil in those areas are rich in nutrients and slightly acidic. It’s best to use soil specially made for Azaleas. Don’t use soil from your garden: it’s often too clay-like for container plants and it may bring pests, weeds and diseases.
Another thing to keep in mind is that soil on the forest floor is cool and moist. Therefore, it’s best to pick terra cotta pots for your shade-loving plants.
When it comes to fertilizers, those made for Azaleas will keep the soil acidic. However, it’s important to never overdo the fertilizer. If you choose potting soil for Azaleas you might not need Azalea fertilizer. Consult gardener and read tags on the plants you buy to find the best fertilizer treatment for your plants.
You should arrange pots in their intended locations before planting because it will be difficult to move them after you have planted the soil. The pots farthest in the back should contain the most soil. Mix a bit of time-released fertilizer. Without removing the nursery pots and arrange the plants in the pot. When you decide on the best arrangement you want to use, gently remove the nursery pot. Make sure to loosen the roots if they are rootbound. Place the plants in the desired location.
It’s always best to keep the base of the plant about an inch below the lip of the pot. Add or remove the soil if needed to achieve that. Also, don’t forget to fill in the holes between the plants with more potting soil.
When all of the pots are planted, water them thoroughly. Make sure not to get water on the leaves.
Caring for Your Plants
Shade plants enjoy moist soil, so it’s best to provide it. Check your plants regularly and whenever the soil feels dry, water them. On the other hand, it’s important to never over-water your plants, since most of them don’t like to sit in water. What you want to have is the evenly damp soil, not soggy. Another thing to keep in mind is to never get water on the leaves.
Shady areas are good places for mold, fungus and mildew growth, so you should inspect your plants regularly to see if they are healthy. If you keep water off the leaves it will help preventing fungus, mold and mildew growth.
You should fertilize your plants according to their needs. Container plants usually need more frequent fertilizing than plants that grow directly in the ground because every time you water the plants you wash out the nutrients from the soil.
Another thing to watch out are pests, such as snails and slugs. They enjoy shade so while they can’t climb high enough on most balconies, in case you live on the first floor you should watch out. If you notice slugs or snails you can simply pick them off to remove them from your plants. There are also certain home remedies you can use to keep these pests away from your plants.
