With January being one of the main harvesting times, lots of delicious summer crops will be ready to harvest and it’s the perfect time to plant more to ensure a continued supply! If you go away on holiday, organise someone to water your plants while you are away.
Find out what else to plant in your region with our planting calendar here.
In the vegetable garden
- Dig in Tui Compost and Tui Sheep Pellets before planting to replenish nutrients used by previous crops. Compost is also an excellent water saver.
- Tomatoes: Bird netting may be required to protect the ripening tomatoes. Continue staking tomatoes, keep pinching out new laterals that appear and keep plants well watered. For the best flavour, leave the fruit to ripen on the plant.
- Potatoes: for main crops still in the ground, mould up soil around the leaves to encourage more tubers and to keep the sun off them. A side-dressing of Tui Potato Food will give them a boost.
- If aphids and whitefly are still a problem, try blasting with a hose or spray with an insect control product from your garden centre.
In the fruit garden
- Pick nectarines, passionfruit, cherries, blueberry, strawberries, raspberries, apricots, peaches, plums.
- Plant more strawberries. Trim long runners back to the centre of strawberry plants, to encourage another batch of fruit. The runners can also be planted out as new strawberry plants.
- Add a layer of Tui Mulch & Feed around the base of fruit trees to maintain moisture and keep the area weed free.
- Aphids, whitefly and scale insects may be about. Blast small infestations off with a hose. For larger infestations spray with an insect control product from your garden centre.
In the flower garden
- Pick vibrant blooms including roses, hydrangeas, fuchsias, dianthus, delphiniums, lilies, gladiolus, sweet peas, agapanthus, sunflowers, geraniums, cosmos, sunflowers.
- Plant petunias, impatiens, calendula, dahlias, echinacea, verbascum, verbena, alyssum, cosmos, gaillardia, marigolds, nemesia, dahlias.
- Deadhead or cut back summer flowers to encourage a fresh batch of flowers.
- Apply Tui NovaTec Premium Fertiliser to flower beds and pots and containers to replenish nutrients. Fertilise roses with Tui Rose Food.
Tui Tips
- Lack of water causes plants to become dehydrated with wilted or curled leaves. To revive dehydrated plants give them a good, deep soak with water and Tui Organic Seaweed Plant Tonic.
- Apply Debco SaturAid granular soil wetter to garden beds and pots to assist water reaching the root zone of plants.

I have been trying to look after my garden with out using sprays. Everything has been going great, until my tomatoes started developing Mildew. I tried spraying them with Milk, told by a Organic person to do, but I'm not sure that has helped. What can I do. Thanks in advance D
Donna Rigg
Mix 1 tablespoon baking soda with 1 tablespoon vegetable oil and 1 teaspoon dish soap in 1 gallon of water.
Chris Thompson

Any tips on keeping the weeds around the veggies down the weeds in my garden are out competing my vegetables and also my tomato plants are huge but not fruitful
Megan
Hi Olivia, we recommend Tui Quash slug and snail control, see here: http://www.tuigarden.co.nz/product/tui-quash-slug-snail-control All the best, Tui Team

Hi Megan, mulching around plants will help reduce weeds as it suppresses weed growth. Find out more here: http://www.tuigarden.co.nz/product/tui-mulch-feed Tui Pea Straw Mulch will also help suppress weeds. For tomatoes planted in garden beds feed every four weeks during key growth periods of spring and summer. Tui Tomato Food is a blend of nitrogen, phosphorus and a generous amount of potassium formulated to promote the growth and fruiting potential of tomatoes. For tomatoes in pots and containers use Tui NovaTec Premium fertiliser. Between monthly applications of Tui Tomato Food, apply Nitrosol Tomato Liquid Fertiliser made from blood and bone with added potassium at 7 to 10 day intervals. This will give your tomatoes an extra boost. All the best and happy gardening, Tui Team

Hi Rita, fruit drop is caused by stress ? water (too much or too little), temperature (hot/cold extremes), nutrition problems and/or pest/disease problems. Some things to consider: - How long as the tree been in the pot? It may need repotting, to replenish the growing media as it can become ?hydrophobic? ? which means the mix actually repels water. Use good quality mix like Tui Pot Power. This contains a six month controlled release fertiliser, so it will need feeding after that. - Have you fed the tree enough? For citrus in pots you need to take care to use a suitable fertiliser. Citrus are heavy feeders so need very regular fertiliser to keep the leaves dark green and glossy (no yellowing, curling or discoloured veins), with lots of new growth and fruit production. Use Scotts Osmocote Fruit, Citrus, Trees & Shrubs for citrus in pots, or Tui Citrus Food for trees planted in the ground. - Are you watering deeply enough? There should be enough water applied that it leaks steadily from the drainage holes in the pot, so that the growing media is well drenched. Mulch with Tui Mulch & Feed to assist with moisture retention. Check the moisture levels on the day you don?t normally water by poking your finger down into the dirt. If it?s damp it doesn?t need more watering that day, but if it?s dry, you may need to move to daily watering. - Is the tree exposed to cold snaps? Cover with protective cloth or move into a warm area if unseasonal cold spells/nights are expected. Limes aren?t frost hardy, so must be protected from frosts. Thanks, Tui Team

Hi Team, I have a problem in the vegetable garden with earwigs....can you supply a solution....
Gaenor
Hi, how late in the season can I plant Apple cucumber and expect to get fruit ?
Bruce Woodcock
Remove all affected leaves and spray with 1 tbs Baking Soda, 1 tbs cooking or horticultural oil + a few drops of dishwashing liquid in 4 litres of water. Spray under/over leaves, fruit and stems at least once every 5 days until it clears up.
Mike
Hi Gaenor, check out our info here on controlling earwigs: http://www.tuigarden.co.nz/garden-problem-solver/fruit-veges/earwig ^Tui Team

Hi Bruce, it is getting late to plant cucumber. Not sure where you live, but you could try putting some in by the end of this month. They have a harvest time of approximately 60 days. Thanks ^Tui Team

Hi when should I plant squashes? I have a number of seeds that I would like to plant. I would also like more info on how to plant and care for squash.
Veronica Labuschagne
Hi Veronica, the exact months to plant will depend on where you live: Aug-Feb in the upper North Island, Sept-Dec in the middle and lower North Island and Oct-Dec in the South Island. Choose as sunny position and dig over the site well. They love rich soil, so add plenty of compost and Tui Sheep Pellets. They require a long growing season of approximately four to six months. Water in the morning where possible and avoid getting the foliage wet. Happy gardening from the Tui Team

When can I plant citrus and stone fruit?
Noel Delany
Hi Noel, for citrus you can plant in spring, autumn and winter (note only in winter where frosts aren't prevalent).
For stonefruit, winter is an ideal time when they are dormant. The widest variety is available in stores then. Check at your local garden centre for the best varieties to grow in your region. Happy growing from the Tui Team
