February Seasonal Gardening Tips – Subtropical Queensland
February is typically the time of year when we get the most rainfall in our climate. Heatwaves, hail and even cyclones. Based on past patterns, we often get heavy downpours and thunderstorms, creating hot humid conditions and temperatures can be very uncomfortable. We have to take the good with the bad during summer.
Long-awaited rain from recent storms has been a relief for many gardeners on the coast after so long in drought. Plants are finally getting a good deep
drink and there’s a reservoir of moisture in the soil for continued growth. However, new growth and wet weather have increased insect populations.
You can literally watch the grass grow under your feet!Time for garden maintenance and careful observation to nip potential problems in the bud.
Issues to watch out for:
- Hot sticky conditions are likely to continue into March and the moist environment creates the perfect environment for diseases like powdery mildew,
black sooty mould and root rot as a result of waterlogging. Soggy soils can become stagnant if drainage is poor. If the soil smells sour, this
may indicate microorganisms are dying off due to lack of oxygen or water pooling, instead of draining away. Learn how to manage waterlogged soil if this is a problem. If you have boggy spots in your garden, aerate the soil or plant more suitable
species to soak up excess moisture.
- If you’ve had some good rain, it’s likely some of the soluble soil nutrients will have leached out of the soil. So plants may be in need of a feed
to support new growth. Applying compost, slow-release pelletised organic fertiliser, liquid seaweed or diluted worm casting leachate and mulch
will help replenish nutrients and lock moisture in.
- Citrus leaf miner. These sapsuckers continue to be a common problem over summer and mainly target new growth on citrus trees. Snip off any affected
leaves and throw in the bin. The sooner the better as they spread quickly.
- Grasshoppers and caterpillars are out in force along with many other bugs, snails and slugs! Many insects can be handpicked off your plants early morning.
Check under leaves, look for slimy trails, damaged leaves or fruit and try to find the culprits at the scene of the crime! My magpie family follows
me around early morning because they love the free protein snacks I pick off. They stay in the kitchen garden finishing off the job and save me
time pest managing. Encourage birds into your garden with fresh water in a safe shady location.
- Fruit flies are also very active and attack many fruiting crops. Learn more about organic fruit fly strategies to minimise this issue in your garden.
After rain, on sunny days as the soil starts to dry out, there will likely be lots of weeds and green ‘waste’ in your garden. Mow weeds or remove by hand
when the soil is soft, before they set seed heads to start the cycle again. Turn lawn clippings, prunings and seed-free weeds into plant food. This
is a sustainable closed-loop cycle that returns green ‘waste’ back into soil to feed crops for your table. All green vegetation can be recycled into
making compost or mulch for your garden, so don’t waste it. Make compost now for autumn planting.
- Keep gutters and drains free of debris and make sure to check your yard for any loose items that could potentially become projectiles with strong winds.
- Check any standing water, especially after rain for potential mosquito breeding sites. Check pot saucers, watering cans and buckets regularly and tip
stagnant water around plants instead.
- Fertilise citrus and fruit trees as they have high nutrient and moisture requirements at this time. Add more mulch if needed.
- Keep up water to bird and bee baths to care for your beneficial insects and pest patrollers. Less work for you!
- Grow crops in container gardens or Vegepods for easy care and more control over microclimates.
- Cover plants with shade cloth or netting to protect from heat, storms and insect damage.
- Stake climbers like cucumbers, tomatoes and passionfruit to provide support as they grow.
