Flooded and Soggy Garden Rescue

An overly soggy garden that dries out over a few days can be revived without too much fuss, but a flooded garden needs a deeper clean-up and a few more steps to keep you safe and get your garden back to health. If plants are left to stand in water for more than a few days, they can die from lack of oxygen supply to their roots and if they do manage to survive then fungal diseases that develop in these conditions may still be a major challenge.
When flood occurs, toxic compounds can wash into your garden such as chemicals, petroleum products and raw sewage along with pathogens and unwanted weeds. Then there is silt. This is a sediment of dust sized partials that move easily in water and when the water recedes, the silt will compact and lead to increased acidity and oxygen starvation in soil. When this silt and mud is left on plants it will also stop the process of photosynthesis. Once the sun returns its gaze upon our gardens, it’s time to get into rescue mode, but not so fast! There is a right way and more importantly, a safe way to save our plants.

First Steps to Recovery
As always, safety first and if your garden was flooded then you need to wear waterproof gloves and boots and a mask is also advisable. This is to reduce the risk of you becoming infected with pathogens. If your garden flooded then you need to wash away any left behind silt and mud from plants, paths, structures, and the surface of the garden as soon as possible. Silt will harden as it dries and be difficult to remove. Get rid of all debris that has fallen or swept into your garden as soon as possible as rotting plant materials will contribute to the spread of disease and fungal activity as well as invite pests in. Let the garden dry out, don’t start planting just yet and do not eat any raw leafy greens, soft fruits, or berries as these will more than likely have absorbed dangerous levels of contaminates. Rule of thumb is to not eat produce for a month, to wash with soapy water and cook before consuming. If you suspect that your garden has been contaminated with raw sewage, then you should remove and destroy annuals and not consume from longer living plants until the following year. 

Soil Rescue
After washing, dig in any remaining silt and turn over soil well to help aerate the garden beds. Your soil will need to be treated with fungicide as well to hold back outbreaks. All that water would have also washed away nutrients and even broken down your soil structure. This needs to be repaired quickly so that your existing plants have a better chance at survival as well. Do a soil test to determine what may be needed to improve your soil and add organic matter, fertilisers, and composts to replace lost nutrients. If you can get hold of a bunch of seaweed, then mulching with this will help increase fertility of soil, break down any remaining silt and encourage the return of worms but any organic mulch will help.

Plant Rescue
You need to be tough and face the fact that some of your plants may not recover but you can help by using fungicides and pest control methods. Use seaweed solutions liberally as these promote strong root growth and are an amazing health tonic for stressed plants. Be ready for competing weeds to start showing up as they move in more easily with silt and remove as soon as you see them. If a plant seems beyond rescue, be strong and remove it as it may infect other healthier plants in your garden.

Lawn Repair
Flooded lawn areas can be saved if the remaining silt is less than about 2cm deep. Try and wash off as much as possible and go over the surface with steel rake to break up the silt surface. Hose on a seaweed solution to encourage root growth. For deep silt, you may need to start again but the trick is to get rid of the silt and to get air into the soil below.

When to Plant Again
General advice it to wait at least 60 days after flooding until you plant again. For those gardens that experienced heavy rainfall without actual flooding, test the readiness by rolling a ball of soil in your hand. If it will easily crumble when pushed with a finger and no water can be seen oozing out, then you are right to plant. If you need to wait, there is nothing stopping you planting your seeds in seed pots and trays while your garden recovers. By the time the seedlings are ready, your garden will have had time to rest, repair and rejuvenate.

FLOOD-PROOF GARDEN
I’m not too sure there is such a thing, but here are a few ways that may help reduce the risk of flood and help water drain more easily from your garden. Create a slope to your garden, even 2 degrees can be enough, so that water runs off more easily and make sure it slopes away from buildings. The installation of drains and even the clever French Drain will help immensely. These are also known as ditch drains, French ditch, sub-surface drains and land drains and they not only help save your garden but will pull water away from the foundation of your home as well. They work by collecting overflowing water and filtering it through gravel or rocks. Selection of plants is always important so considering planting more natives as these will generally be more adaptable to conditions and to recovery as well as helping stop possible soil erosion. To direct water away from your house and to store for later use, install a water tank and consider rain barrels under your down pipes. Collected water in these can be used for the garden later.

YOU AND YOUR GARDEN
Soil to Plate with Youth Connections and SWAMP


Sustainable Wetlands Agricultural Makers Project (SWAMP) at the Central Coast Wetlands is facilitating an amazing project with Youth Connections of Tuggerah. Created with the support of Central Coast Council and delivered by the enthusiastic volunteers of SWAMP, it is a grass roots pilot program aiming to deliver a nature, gardening, cultural and educational program for the young clients of Youth Connections. In the spirit of ‘soil to plate’ the project will see the creation of a ‘pizza garden’ and then the cooking of pizzas to share with family and friends. In the first week Youth Connections participants travelled to Narara Valley Nursery to begin the preparation and decision making around what will be needed to create the pizza garden. The youth engaged with decisions about which soil, what seeds or seedlings they might like in their garden, as well as the smells and sounds of a bustling nursery with a wide variety of plants. In the following weeks an above ground garden was established at the SWAMP community garden site by the group for the selection of herbs and vegetables that will eventually find their way into on to the pizzas. Other activities included kitchen apron making and a joyful visit to Grace Springs Farm in Kulnura which enabled all to experience agriculture on a larger scale.

Growing Your Own Garlic

Fresh garlic, straight from the garden is a divine experience and it is also the way to ensure you get the maximum health benefits possible. It is garlic planting time on The Coast and across temperate areas of Australia right now. Good news is, they are one of the easiest plants to grow and home-grown means more flavour and nutrients. This wonderful veggie can be planted in pots and garden beds and can be used fresh or stored for use all year-round. Garlic (Allium sativum), probably originated in the western areas of Asia, but it is such a long-cultivated plant that we cannot be completely sure. The Ancient peoples of Egypt, China and India, all have recorded histories of growing and using garlic as a medicinal and culinary plant with some even attributing mystical properties to it. Most commercial garlic is treated with a chemical to render it sterile, so you won’t be able to use those bulbs for propagation and it’s handy to know that there are two types of garlic, ‘hard-neck’ which has flowers and ‘soft-neck’ which does not. Soft-neck garlic will store for longer than it’s hard-neck friend, but I do like the flowers which are also edible, and the spikes make amazing, dried foliage material. Another factor you will need to consider is that you probably won’t end up with as large a bulb size as you find in the shops, but you will have leaves and you can eat those as well. Types to consider: Dynamite Purple, Spanish Roja, White Crookneck, Giant Russian, Melbourne Market.

Grow Your Own Garlic
Soil must be open, free-draining and well-prepared with compost. pH level sitting between 6.5 and 7.5 is best and whether you decide to grow in the garden or in pots, find a sunny spot. Garlic can be planted by seed but is mostly cultivated via bulbs. To do this, gently separate the bulb into individual cloves and only use the larger ones. Plant directly in their final designation into the soil with the tips just below the surface and firm down.
Garlic is not a fan of weeds so keep it tidy and water should be consistent but don’t drown your plant. They just don’t like to get soggy feet or humidity. Water seedlings a few times a week until they are a couple of months old and then back off to once or twice a week. Feed every second week with a seaweed-based fertiliser, as they love it and mulch with your usual veggie garden mulch medium but ensure you don’t crowd the plants as air flow and low humidly are important.
Harvest most varieties at around the five-month mark but this will depend greatly on type. You will know they are ready as the leaves will begin to wilt and yellow around this time. Lift gently, keep the leaves intact and hang to dry for a few weeks in a warm, sheltered spot to cure before storing in a cool, dry, dark place. The leaves are left on during the curing process so that all additional nutrients are pulled down into the bulb. Don’t forget to save some of those bulbs for next year’s planting. You can find garlic to grow at your local nursery or online: diggers.com.au or theseedgarlicshop.com.au and Giant Russian Garlic: naglesfallsfarm.com.au

Garlic Uses in the Garden & Beyond
Along with growing garlic, make this spray from it to combat pests in your garden. Blend together 4 cloves of garlic with 1 cup of water and a teaspoon of dishwashing liquid (not antibacterial), strain into 500ml spray bottle and top with water. Spray onto plants to deter pests. Test on a few leaves first.  Garlic is a brilliant companion plant for beetroot, carrots, strawberries, lettuce, and roses and provides a fair amount of protection from various pests, but it should never be planted alongside beans or peas as it will stunt their growth and production. For medical use garlic has been used as both an antiseptic and an antibacterial agent for over 3,000 years. Garlic is still used for these reasons in herbal medicine today along with treatments for digestive issues, respiratory diseases and for circulatory benefits as well.

Garlic Folklore
Firstly, don’t go giving garlic flowers to those you love because in the Language of Flowers and Plants, it means ‘Go away you evil one.’ Could be handy at other times though, so hold that thought. As much as we in Western cultures would like to believe that garlic has always been considered the great protector and many points throughout history support this, it’s just not always the case. While you will find that along with traditions, such as the roasting and sharing of garlic cloves on Midsummer’s Eve in France to use as protective amulets, garlic was forbidden in many cultures at times. It was looked upon as ‘unclean’ by religions including Hinduism, Islam and some sectors of Buddhism and Christianity at different times. The Ancient Greeks thought that garlic-breath was an offence in their some of their temples and so consumption was banned before worship.
The protection myths though are very plentiful and are probably related to the obvious health benefits that garlic shares. It’s not just Dracula and other vampires that are said to fear this plant but all demons and evil spirits. The Sanskrit name for garlic, ‘Ishunm’ translates to ‘slayer of monsters’ and it is thought throughout many folklores around the world that sleeping with a clove under your pillow will indeed protect you from such evil-doers while sleeping and from nightmares.

GARDENING BOOK REVIEW
Gardening for Everyone, Growing Vegetables, Herbs and More at Home
by Julia Watkins, Little Brown Publishers, 2022. 304 pages, ISBN: 9781472146922

This gardening book is big on planning and in my book? That makes it a winner straight off the block. Julie Watkins focuses strongly on sustainability and very much on long term goals. Her advice is peppered with personal accounts of her mistakes and lessons and that makes gardening more accessible for those wondering about their own past challenges or current aptitude. The book is encouraging and to beginners and I feel expansive enough for more experienced gardeners looking for sustainability gardening practice information and inspiration. Big on beautiful photographs to light that spark in us all and a clever section called ‘Play’ that brings fun and creative ways you can add joy and usefulness in your garden spaces. My only little gripe here is that the title is not a good fit and being an author myself, I know this is usually a publishing house issue, not necessarily an author one. The contents and advice miss the mark with many gardeners as it focuses primarily outdoors and for those with no limitations. Other than that, a good and rather lovely sustainable gardening book.
