For me, gardening is pure theraputic joy. It's communing with nature.

I love creating exterior rooms of colour to relax in.

Being an apartment dweller, some people can't believe I have an extensive garden – my vast estate – on my balcony. Then I show them the pics... and they are amazed.
Here are a few pointers I've learnt from Burnley Horticultural College
to help with your gardening in a small space...
1. Take note of the light conditions your plants will get. My balcony faces due west and I get the scorching heat and hot winds of summer. Through experimentation I've put in drought loving plants and those from the tropics to survive.

Last summer some survived, others didn't. In fact, the ones that enjoyed the 46 degrees of Black Saturday was my Mango tree (a seedling dug from the compost) and various Bougainvillia.
2. Stack hanging baskets under each other with similar habits and needs – watering one waters the others.

In this way, my balcony has 21 baskets, all creating a flourish of eternal colour and aromas.
3. Some plants in hanging baskets are meant for growing in the earth proper. But because they will attract birds and bees, I reckon you can grow them in hanging baskets. For instance, my yellow Grevillea, left, should grow 2m but I doubt it will.
4. When planting in pots, avoid 'crocking' and placing the pot in a saucer. See the importance of feet.
Also in amalgam, see how to make your Bird of Paradise flower continually.
And read about the NPK story. It'll inspire you toward great gardening excellence.
