Making use of waste

We like finding opportunities to turn waste into something useful.  Why buy something when you can find a suitable free resource? We've talked about how we make compost from the collection of workplace kitchen scraps here, but that's not all we collect for free to use in the garden.

Mulch. All gardeners know the value of mulch in helping to prevent water loss from the soil, suppressing weed growth, and as it breaks down, adding nutrients to the soil.  We have a reasonably sized productive garden and would be spending plenty of money on mulch....if we had to buy it.  But we don't.

A suburb or two away from us is an arborist business. These kind folk leave piles of woody mulch on the naturestrip in front of the business for people to cart away for use in their own gardens.  

We pull up in the car with a bunch of bags and a spade and fill the car with bags of mulch. The bags we use are also recycled from a friend's factory who would otherwise have to throw them out.

This woody mulch gets used in the garden to make pathways and suppress weeds.   Before spreading it we mow/pull out most of the main weeds and then cover the ground with thick overlapping layers of newspaper.  The newspapers have been recycled from my workplace for use under the hay bedding in our guinea pig hutch before being used again with the mulch. Double recycling in action!  

Once the layer of newspaper has gone down the mulch goes on top in a nice thick layer. Eventually this woody mulch breaks down and then we move it onto the garden beds....and make another trip to the arborist to load up on some more.

 By taking this mulch we are helping the business to deal with what would otherwise be a waste product they'd have to dispose of some other way. In the process we are getting a free source of something that we'd otherwise have to pay for. Everyone wins.

Sometimes we've even done a deal with a local arborist to get a truckload delivered if they happen to be working in our neighbourhood. Bartering some home produce for a truckload of mulch. Seems like a good deal to us 😊

Garden raiders

Our loquats didn't have time to ripen this year before these garden raiders were back....

Our garden is definitely on their spring calendar.

In the garden .....

After a cold (by Melbourne standards), wet winter, there are sure signs in the garden that Spring is finally here....

Has Spring arrived in your garden?

Moving the hive, temporarily

We got our backyard hive almost 5 years ago.  Prior to installing the hive we'd leveled and paved an area with bricks on which to place the hive.

Unfortunately, 5 years on, our hive location needed a bit of renovation.  The nearby stand of clumping bamboo had decided to make an appearance directly under the hive.  It's tough stuff - see how it has raised the bricks, the heavy concrete slab and the hive? That's quite a bit of weight that has been lifted.

The hive was no longer level and action needed to be taken quick smart. Unfortunately there are no other suitable spots in our yard for a hive so we needed to fix its current location.

This meant we had to move the hive elsewhere in the garden for a day while we dealt with the bamboo.  Moving a hive is not a small job and in our case we needed to keep the bees contained within the hive for a day, while we worked on fixing the hive location.

I knew we had to keep the hive well ventilated so the bees would survive inside for a day, so I did some thinking and asking around for advice. I decided to use plastic flyscreen to block the entrance and then add a an additional box onto the hive with the top covered in flyscreen for additional ventilation.  

Here's how we went about the hive moving process:

Around midday on the day of the planned move I secured the flyscreen to the top of an empty super and put this on top of the hive so that the flyscreen side was directly under the lid.

Then we waited until dark, suited up and taped a piece of flyscreen over the entrance to keep the bees inside. Sounds easy, right?  Well not exactly.  As soon as I started taping the flyscreen to the entrance the bees started trying to come out.  It might have worked better if I'd been using stiff wire flyscreen instead of plastic. The entrance of the hive was almost as wide as the box so it was difficult to tape it on quickly while trying to hold it in place so the bees couldn't pour out.  And being dark, Mr PragSust had to hold a torch above so I could see what I was doing ...and of course that light also got the bees active. I started off wearing gloves but they were too cumbersome to be able to manage the tape and scissors so off one glove came. And yes I got stung on the hand but it could have been a lot worse.  Some time and a lot of sticky tape later the entrance was closed. Then we had to move the hive.  That went surprisingly well and the hive was soon in its new, temporary spot. We hoped that not too many bees came out so that we wouldn't have to suit up to do the garden works tomorrow.

The next day I was pleased to see that the stickytape was still in place and few bees had returned to the old location.  I was glad I'd added the extra screened box because the bees were piling up at the entrance and blocking any ventilation in that way.

Because I am a bit sensitive to bee stings, I suited up to do the garden work, but Mr PragSust didn't bother.  Our plan was to remove the brick pavers and the edging and dig up the area underneath and remove all the bamboo roots.  Then we would dig a trench and put in some root barrier to stop the bamboo roots spreading back towards the hive. 

The only root barrier we could get at short notice was 60 cm which was a bit higher than we needed. As we were under a bit of time pressure to get the job done we took what was available as we knew we could trim it back later.

Removing the roots wasn't too much of a drama. I should have taken a photo showing the large amount of root mass we removed, but I was too busy digging. We dug up the whole area, making sure we'd removed all the roots. There were a few bees flying around but they were more confused - as in 'where's my house gone?' - rather than aggressive.

What took most of the time was digging the trench for the root barrier. After our very dry summer the ground was like concrete. We had to use a round fencing bar to break it up.  Mr PragSust did the hard work of pounding up and down with the fencing bar while I used the trenching shovel to remove the loosened earth.  It took ages to dig the trench.  Although the bamboo roots seemed to be fairly shallow, we didn't want to be doing this again so we dug the trench to well below the level of the roots. After much hard work the trench was deep enough to install the root barrier.

The root barrier went in and we back-filled the trench with earth.  Mr PragSust went off for a well-deserved break while I finished off the process. I smoothed the earth over the area, replaced the wooden edging and spread woody mulch (obtained for free from the local arborist) over the whole area. We weren't planning to replace the brick pavers even if we did have the time (which we didn't). The concrete paver on which the hive sits was put back in place and leveled with a spirit level.  Then the wooden stand for weighing the hive was put back on the paver, raised at the back with a long thin piece of paving stone. All ready for the hive to come back. We carried the hive back and gently placed it on the stand and Mr PragSust knocked off for the day.  I removed the top box and replaced the hive mat and lid. Then I gently removed the tape and flyscreen from the entrance.  I thought after being cooped up all day the bees would have been pretty agro but I was pleasantly surprised.  I quickly moved away from the hive but I wasn't chased. An hour or so later and all was calm again.

Here's the hive back in position:

You can see the black root barrier curving around the corner of the stand of bamboo. We haven't trimmed it down yet.

All in all the whole process went pretty well.  The only stings received were the ones to my hand when I was trying to tape up the hive entrance.  The work did take most of a day so I was glad we had provided adequate ventilation for the hive. The empty box was definitely required as the bees blocked up the front entrance trying to find a way out. Without the additional ventilation they would most likely have over-heated and we could have lost the hive.

Lessons learnt:

• We need a better way to quickly and securely block the hive entrance while still allowing ventilation. Maybe something like flywire with a framed wooden edge that could be quickly slotted in place with the framed edges flush against the hive, preventing the bees from escaping, and with some quick way of securing it in place. 

• Plan as much as you can beforehand for the job and be prepared with all necessary equipment. We really needed the fencing bar and the trenching shovel for this job.

• Things always take longer to do than you think!

Preserving the harvest - Cumquat marmalade

Our little cumquat tree fruited well this year. We like to give home produce as gifts so this weekend we turned the harvest into cumquat marmalade.

Here's the recipe we used. It's based on one published in The Age newspaper, many moons ago.

Cumquat Marmalade

Ingredients
1 kg cumquats
5 cups water
2 tblspn lemon juice
5 cups sugar

Method
1.  Wash the fruit and cut them into quarters, removing seeds and placing them in a small bowl.  Using containers with lids, soak the seeds overnight in 1 cup of the water, the fruit in what remains.

2.  Transfer the mixture to a large saucepan and stir in the lemon juice.  Bring to boil, then reduce heat and simmer, covered, for 30 minutes until cumquats are tender.

3.  Add sugar, stir over heat without boiling until sugar dissolves.  Bring to boil over high heat , then continue to cook, uncovered, without stirring for about 20 minutes or until marmalade jells when tested.

4.  To test if the marmalade is ready place a teaspoon of it onto a cold saucer and place in freezer for 2 minutes. Remove from freezer and press your finger gently against the marmalade to see if it wrinkles and has formed a skin. If not, keep cooking the marmalade for another 5 minutes, then retest.

5.  When ready, remove from heat and allow to settle for 10 minutes. Scoop out any remaining pips at this point and discard. Pour into hot, sterilised jars and seal.

To sterilise jars: Wash in hot soapy water. Rinse. Place upside down on tray in warm oven (120 C) for 20 minutes. Useful to keep in oven while making the marmalade. Sterilise lids by putting them in boiling water for a couple of minutes. 

Bee tongue!

It's been a while since we've posted a backyard bee picture...

I've never noticed a bee flying with its tongue out until I took this photo:

 Neat huh?

In the garden - they're back

It's that time of year again when large flocks of little corellas descend on our street to feast on the street trees. 

They're earlier this year - last year they visited us in May.

It's too darn hot

Another 39 C day - yuk.  Summer in Melbourne can be just too darn hot.  While we and the pets spend time inside in front of the fan, the beehive gets at least some of the hot afternoon sun.

Here's what we do to spare the girls some of the heat.

A polystyrene box full of water and foam floats is placed on top of the hive. 

Not only does the box of water insulate the hive by stopping direct sun hitting the lid, it also means the girls don't have to travel far in search of water to cool the hive.

We also lean a sheet of masonite (foraged from a hard waste collection) against the side of the hive to shield it from direct sun. The masonite board is heavy enough to stay put in mild winds, and the hive location itself is sheltered from the wind, so the system works well.

In addition to observing the hive, we weigh it on a regular basis to get an idea of what's going on inside.  It has been interesting to note this year how quickly the weight dropped over the hot days. Some weight loss is not surprising - instead of bringing in nectar, the foragers are out gathering water to use to cool the hive, and they are consuming their stores in order to have the energy to make the flights. What surprises us is why we didn't note a similar weight drop over the extended hot period we had in Melbourne during the summer of 2014.

How do you manage your hives in summer?

Beautiful garden pests

Our fruit trees are being ravaged, by garden pests of the most attractive kind:

Rainbow lorikeets (Trichoglossus haematodus), are very common in our area, and particularly so at our place. Males and females look alike with a mauve head and belly, green wings, tail and back, and an orange/yellow breast. 

Our yard must be like a smorgasbord - apricots, plums, pears, apples, nectarines, peaches, they devour them all, well before they have a chance to ripen.

They are not discouraged easily.  Stern words and shaking of the tree branch are just met with at "yeah, whatever" look.  Secure netting will give them pause, unfortunately we were a bit slow in that department this year and our trees got too big for us to net.

Just as well they are so cute....
