Monitor watering on new and recent plantings as wind and hot sun will quickly dry the soil out again.
Mulching with organic material helps retain moisture, creates a suitable environment for surface feeding roots essential for healthy growth, protect the soil from compacting and erosion during heavy downpours. Mulching constantly adds organic matter to the soil, controls weed growth and improves appearance of garden beds. Mulch immediately after planting with organic compost, mushroom compost, pea straw or similar.
Tomato/potato blight – affects tomatoes and potatoes. Patches of brown discolouration develop on the leaf tips and edges; in damp conditions these can often be ringed with a white, fungal growth. It is caused by a fungus that thrives in warm moist conditions and spores are carried from plant to plant by wind and rain and may be washed down into the soil to infect potato tubers. To control; avoid overhead watering and earth up potatoes deeply to provide a barrier for the tubers against falling spores. Protect both tomatoes and potatoes by spraying thoroughly with ‘Grosafe Freeflo Copper’, this is a certified organic fungicide which is a very effective preventative spray.
Remember that strong healthy robust plants resist pests and diseases far better than weak unhealthy ones. Regular feeding and watering is the key to this. ‘Tui Organic Seaweed Plant Tonic’ increases resistance to heat, drought, pests & diseases. Use this in conjuction with other fertilisers to maximise plant health.
Control may be necessary for pests at the moment including; caterpillars, aphids, mites, grasshoppers and whitefly. ‘Yates Confidor’, ‘Mavrik’ and ‘Nature’s Way Pyrethrum’ insect spray are suitable insecticides for control of those pests.
Add ‘Debco Saturaid’ to any pots, hanging baskets or garden areas that are drying out excessively and water fails to penetrate the mix.
Make regular harvest of vegetables and fruit as they come ready.
Continue watering and feeding tomatoes with ‘Tui Tomato Fertiliser’ or ‘Jobes Tomato Spikes’ for those growing in pots.
Continue to plant successive crops of lettuce, cabbage, cauliflower, broccoli, celery, spinach and silverbeet.
Time to make plantings for leeks & brussel sprouts that will then come ready in the early winter months.
Sow seeds of carrots, peas, dwarf and butter beans, radishes,
