gardener’s secrets - annuals
Placement & Planting Tips
Place plants according to sun/shade tolerance. Also take into account growing conditions, such as downspouts, and shady spots.
Plant slightly deeper than pot level, usually about 1cm. Cover the old root ball.
Start seeds indoors according to the seeding dates on pages 11 & 12 of this book. Beginning gardeners might want to try the Jiffy Professional Greenhouse.
Seeds for annuals can be planted outdoors as soon as the ground can be worked. McKenzie Seeds offers a huge variety of quality seeds.
Watering Tips
Water slowly and deeply soaking the root ball regularly depending on conditions. More water is required when temperature is warmer.

Feeding Tips

various
Aerate the soil with the mineral Zeolite, which helps to promote the slower release of nutrients and also helps to break up clay.
Feed annuals with regularity using a good quality fertilizer. A good choice is Nurseryland Power Bloom.
Maintenance Tips
Deadhead flowering annuals to extend the flowering season. Deadheading is removing spent flowers to encourage re-blooming.
