Citrus trees can suffer from sunburn. In Australia we have some serious sun and in summer time with no protection, some citrus trees will get burnt. There’s a lot of things we can do to help prevent it. Here are three simple ways to stop the burn and save your trees.

Provide part shade

Provide some shade for your tree by putting up some shade cloth. If your tree is in a pot you can move it into a shadier location. For some of my smaller trees, I put shade cloth on one side and it saves them during the major heat of the day. 

You’ll find that the leaves will green up, get softer and grow larger in the shade. Adjust the amount of shade for each tree as their requirements are different. 

Oh and yeah, this is great for some fruit too. I’ve found our lemons don’t burn as badly with a little shade. 

Paint the trunk white

Grab some paint that will last (water-based latex paint) or find tree trunk paint at your local home hardware centre. Some people mix it with white acrylic paint. 

Paint the bottom two thirds or wherever you see sunburn. You’ll see the bark turning brown and eventually dying off if it’s getting burnt. 

It’s like sunscreen for trees!

Mulch around the tree

Mulching a few inches around the base is a great way to save water, keep the citrus tree roots moist for longer and trap some of the heat into the soil. 

Mulch the width of the tree. 

Other ways to prevent burn

Water your trees before hot days. The night before is good so they’ve had adequate time to soak up the water. 

Burlap barriers. These can be used instead or as well as the white paint method. However be mindful to keep checking where it comes into contact with the tree bark and no rot is forming. 

Put geofabric around the base. I wasn’t a fan of this tbh, but I tested it and it’s worked well in smaller pots to reduce evaporation. 

Reflective heat off building or other surfaces. I have a corner of the garden where three trees sit in an area with three light coloured walls around them. There’s quite a bit of radiant light and heat coming off the walls and the trees struggle. 

I think I’ll be moving them soon. 

Don’t prune during the heat of summer. It opens up wounds which enable water loss through evaporation. I’ve had trees die on me because I cut branches off during summer. 

I hope these help, leave a comment if you give these a try.

Citrus tree cuttings are one of the easiest ways to clone a fruit tree. Just by taking a good size cutting and getting it to strike, you can have a cloned tree very quickly. Here’s one of the ways I duplicate citrus trees in my garden. 

In Australia I do it right after fruiting and the warmth of summer is perfect for striking the cuttings in a humid container.  

Gather your cuttings

Figure out which tree you’d like to duplicate and choose the right time to take some thicker cuttings from it. A good time is when it’s not fruiting or flowering. 

Cuttings that have a higher probability of survival are, 30cm / 12″ or longer and as thick as a pencil or thicker. The thicker and longer the better chance of it surviving. I get pretty much 100% strike rate with cuttings that are thumb thickness. 

Preserve or plant

Plant your cuttings immediately (to strike them) or you can put them away to keep them for later. To preserve them, put them in a zip lock bag and put them in the fridge. 

Plant in a container

To root your cuttings, plant them in a clear container with a removable lid. I’ve tested coco peat and soil and a mix seems to work well. But just soil will work fine. 

Plant your cuttings at 45 degrees. 

Keep them in the shade

Put the lid back on and keep the container in the shade. The soil needs to be slightly moist. Too wet and the cuttings will go mouldy and start to rot. 

Open the lid and air them out every few days. A slightly loose fitting lid helps with trapping the humidity in but also letting oxygen in. 

Wait till roots sprout

After a few weeks, new leaves will sprout from the cuttings. The roots won’t come until a month or two later. Once they have roots 10cm / 4″ long (you might be able to see from the side of the container), then they’re ready to plant out.

Plant your tree

Carefully remove the cuttings and plant your lil trees in pots. The roots are fragile so be careful. Keep them moist and in the shade for a couple of months. Then they should be ready to plant outside. 

You’ve done it! You made yourself a whole bunch of new citrus trees. Not long before you’ll be enjoying the fresh fruit!

How I grow stone fruit trees from seed. There’s a huge variety of stone fruit and if you’re lucky to live in a climate where they grown, they’re so delicious and amazing trees to have in the garden. 

Grab your favourite stone fruit

In this case I chose peaches. I love the white peaches in particular. It’s a habit I picked up in Japan where the white peaches are so big, they’re a meal in one. Eat your fruit and save the pit. 

Give it a rinse to get the flesh off, it will be easier to handle.

Hammer time

Grab a hammer (or you can use something else solid – a brick) and hit the pit gently on the seam. It will eventually crack open. Hit it repeatedly but gently. If you hit it too hard you’ll likely smash the soft seed inside. It takes practice. 

Check the quality of your seed. 

Prepare your seed

If the seed looks pale yellow and dried up, it is likely a goner. Your seed needs to be round and firm. Put it into some water for a few hours to rehydrate. 

Plant your seed

last your seed into a pot, a sandy soil seems to be good. 2-3cm or 1″ deep is plenty. Keep the soil moist and put it in the shade. Full sun will likely kill the seed. 

You got peaches!

After a month or so, your seed will germinate and a small seedling will grow. Keep it in the shade and grow it to 40cm or 1ft. Bigger if you’d like. Then plant it in the ground in a sunny position, water it often and mulch the base. 

Put plenty of organic matter in the hold when you plant it. Fruit trees love that. It will take a few years, but eventually you will have grown a beautiful peach tree that bears lots of yummy peaches!

I’ve grown lots of stone fruit trees this way. I have several nectarines growing via this method at the moment. Good luck!

Mulberries are awesome trees because they have so many uses and are real easy to propagate. The cuttings will root if you leave them lying on the ground and they have enough water. 

Here’s a few tips on how to grow your own mulberry trees from a cutting using wax. 

Grab a mulberry cutting

Get yourself a cutting off a healthy tree. You might able to find a tree in a public space in your neighbourhood, a neighbour may have one or you could order online. 

A cutting that’s thicker than a pencil, 30-40 cm or 16 inches or longer is good. The thicker and longer, the better chance of survival. Anything thinner than a pencil may not survive and may need lots of attention. 

Prepare your cutting

Keep your cutting(s) in the shade. Close off the open parts where you cut (not the base) with some wax. I use baybybel cheese wax because we eat the cheese! Put the wax in a jar lid and melt it with a candle or other method. You can just use candle wax too. 

This closes off the open wounds on the cutting so that water doesn’t evaporate the and cutting dries out. 

Plant your cutting

Plant your mulberry cutting in a 10L or 2.5 gal pot. Water it in and mulch it. Any neutral soil that’s a little sandy and has lots of organic matter will suit.

Place your potted cutting in a shady spot to settle and root. 

Leaves will shoot

Wait for a month or so and your first leaves will start to shoot from the cuttings. The cuttings won’t be rooting yet, so keep watering and be patient. I water every couple of days or daily in summer. Keep your pot in the shade. 

You got mulberries!

A few months later your cuttings will be small trees, rooted and producing small berries. The first berries will be small and not really the yummo. Plant your tree in the ground in a place where it has access to water and sun and it will thrive. 

These trees (unless it’s a drwarf version) will grow up to 5m / 16 ft so give them some space. You can trim them aggressively and make more cuttings. 

Enjoy your berries!
