Spring

Zinnia's are best planted from Spring and into Summer.

Prepare

These show stooping vivid annuals make a great display when planted in the garden or on the patio in containers. Great for floral work and to entice bees and butterflies into the garden.

Position

Zinnias prefer a position in full sun, with some protection from strong winds. They can also be grown in containers.

Soil

When planted into the ground Zinnia prefer a free-draining soil that is rich in organic matter. To improve the organic content in your soil, break up the soil and add Kings Compost and Kings Sheep Pellets then mix together well. When growing in containers, plant into Kings Container mix. This mix contains Saturaid, which helps with moisture retention in the soil.

Plant

When planting into the ground, gently tap the plant out of its pot. Dig a hole twice the depth and width of the plant’s root ball. Mix Kings Compost into your existing soil at a 50/50 ratio, add Kings Sheep Pellets, then mix together. Backfill the hole with this soil, so that when planted the top of the plant’s roots sit level with the surrounding ground. Firm the soil down gently and water in well with Aquaticus Organic Garden Booster. In heavier clay soils, where drainage is likely to be an issue, plant onto a raised mound and sprinkle Gypsum Clay Breaker into the bottom of the hole, this helps slowly condition the soil and help to break down the clay. When planting into containers, plant into Kings Container Mix, as this has water retention crystals in it, which will help in keeping the soil moist.

Care

Watering

Once established Zinnias can cope with a small amount of dryness. Water so that the soil is kept moist to keep the plants growing well.

Feeding

When planted in the ground liquid feed every month with Aquaticus Organic Garden Booster, from Spring through to the end of Autumn, this encourages root growth and increases the microbial activity in the soil. Monthly applications of Kings Sheep Pellets will help with soil conditioning and plant health. If planted into a container, feed with Kings Liquid Fast Food along with monthly applications of Aquaticus Organic Garden Booster this encourages strong roots and a healthy immune system.

Protecting

Protect from slugs and snails by applying quash slug bait, remember to re-apply after rain.

Mulching

Mulch around the base of the plants (making sure it is not in direct contact with the trunk) with Living Earth More than Mulch. Mulching helps to reduce weeds as well as aiding the soil to lock moisture in the ground.

Spraying

Leaf spot and other fungal conditions along with aphids and caterpillars can be an issue. Spray with Yates Super Shield as a preventative measure.

Pruning

Deadhead fading flowers to encourage new growth and more bloom's.

Beginner Tip

Since they are prone to powdery mildew and other fungal conditions that thrive in areas with poor airflow, it is important to space your plants appropriately to provide good air circulation.

Tip

Plants can range in size from six inches to four feet tall, with single, double, or semi-double petaled flowers of many different shapes and colors.
