Q.
Hi, I planted my passionfruit last year and it grew well. I got about eight passionfruit and they were a good size. I thought I would get more this coming year, however my vine leaves are yellow and the new growth sparse. I have fed with horse manure, potassium and plant food with no affect. Can you help please? Thanks Vivienne.
A.
It sounds like they may have had too much fertiliser. Too much fertiliser can have the same effect as too little. The weather has also been very warm lately. Also, passionfruit need at least 18 months to two years to establish. Any animal manure must be well rotted and not fresh as this can cause the roots to burn. Ease off the potassium as the plant food will also contain potassium.
Regularly apply Tui Organic Seaweed Plant Tonic every 7 days at a rate of 70mls per 9 litre watering can. Once you see it pick up then cut the Organic Seaweed Plant Tonic back to every two weeks and 30mls per 9 litre watering can. Feed passionfruit in spring with a nitrogen rich fertiliser such Tui NovaTec Premium fertiliser (a slow release fertiliser) when it is going through its leafy growth phase until it starts to flower.

Yellowing and fruit not ripening up and shriving up on passion fruit vine
Collett
Hi Collett, have you fed your passionfruit vine? We suggest feeding with Tui NovaTec Premium fertiliser and applying Seasol seaweed plant tonic to give it an overall boost. Thanks, Jenna - Tui Team

Hi, my passion fruit is getting yellow leaves, & I saw one of the fruits being wrinkly, I have dried chicken manure a few wks bak & also last week epsom salts, 1.5 spoon in 4 litres of water & watered other plants with it too... now I don't understand why its looking sad & yellow, can u help, I live in Cyprus that is quite a warm weather for the time we're up to 30 degrees?? any advise will be much appreciated.. thank u
Pamela Vorka
Hi Pamela, your plant may have mites, these are tiny insects which live under the leaves and cause the leaves to shrivel and the fruit to distort. They are tiny to see, but if they are there it is the most likely cause of your issue. Spray with something that is registered to treat the problem. Thanks, Jenna - Tui Team.
jenna
ok try not to move the vine when picking etc it will kill the vine if flexed too much , epson salt , a few table spoon per litter and iron sulfate again table spoon or two per littler , saying all this I working from the point of view of a clean slate , plant another few plants foot or two apart
richard
My passion fruit vine has yellowing leaves and I've noticed a couple of the fruit are shriveling. I have feed my vine with citrus fertilizer and water regularly every day as up here in the north our temperatures have been in the 24+ degrees each day. Can you me. Thanks
Dean Love
This is my 1st time ever growing Passion Fruit. I have been using Seasol Complete Plant Food . I live in New Plymouth New Zealand.
Patricia Wilson
I planted my passionfruit plantsin january 2016 or thereabouts... one on each side of the fence. The one on the northern side died off due to pricklespray on it but the other thrived hard out. It is grown heaps with lotsa fruit but just in the last two days the leaves have started to turn yellow. What could be causing this to happen.
Dianne Conroy
Hi Dean, yellowing leaves are normally a sign of an insect infestation or a problem in the soil. Hold off adding any more citrus fertiliser to the plant, and apply Seasol plant tonic once a month for the next few months, this may help sort out a soil issue. Look carefully at the undersides of the leaves, you may find tiny insects called mites which may be sucking the sap out of the leaves, spray these with an insecticide, making sure the spray coats the undersides of the leaves. Passionfruit will shed excess leaves and fruit if the crop is exceptionally heavy. Thanks, Tui Team
jenna
Hi I planted my passionfruit in spring it was loaded with fruit however they dont seem to brown they just shrivel up and have patches on the outside of the skin, i sprayed fungi spray to try to save them but i dont think its working would you know whats wrong
Charlene
Hi Charlene, what a shame, and dealing with fungal problems once they appear on fruit is hard and very challenging and often not successful. Suggest you cut your plant back now, forgo this season?s fruit and set about getting your plant healthy for next season. Once you have cut it back give it a good covering with fungal spray, 2 or 3 times over the next month, as well as an application of Seasol plant tonic, to give the roots and immune system a boost. All the best, Tui Team
jenna
Hi Dianne, yellowing of leaves is usually a sign of a lack of magnesium. We suggest feeding with Tui NovaTec Premium fertiliser. Tui Epsom Salts will also help with yellowing of leaves. All the best, Tui Team

I have a huge fig tree that bears 2 crops each summer - it's always loaded with fruit but the figs usually drop off the tree on the first round before they ripen. On the second crop there isn't enough summer left and most are smaller and dry inside. Should I prune off the first figs when they appear? What can I do to get a decent crop? It's in the Nth Wairarapa.
Kuini
Hello, I have two passion vines in pots and at the beginning of our season were growing very well. I had a few roses with black spot so I just gave everything a spray with a combination fungicide/pesticide/mitigate and fertilized a few days later. The purple cultivar has pale washed out yellow looking blooms and both have no new growth. What have I done?
JulieG
Hi Kuini, this is a very common problem, often it occurs when the plant is inconsistently watered, the plant aborts the fruit it can't hold. This is probably the cause of your first lot of fruit falling from the tree if you had a dry spring or summer. For the later crop it is often poor pollination. Thanks, Tui Team
jenna
Hi Julie, at this time of year passionfruit looks like its sulking a bit, the plants can drop there leaves and loose there vigour, depending on what part of the country you live in. However you may also have mites, these are a tiny insect which live underneath the leaves and are very hard to spot, the symptoms are the same. Have a look and see if you can see them, they are pin head size. If they are there spray with Tui Insect Control for Fruit & Veges this will kill the hatching eggs as well as the adults. Follow the instructions on the pack. Apply Seasol plant tonic now (and every few weeks), this will give the root zone a boost, like a shot of vitamin C. All the best, Tui Team

Planted passion fruit plant this year. Leaves are turning yellow. Need advice
Nangnem
When you buy garlic seed bulbs do you divide them or plant the whole bulb?
olive inglis
Hi Olive, you break up each bulb into cloves, rather than planting the whole bulb. Check out our Garlic Growing Guide here: http://www.tuigarden.co.nz/howtoguide/garlic-growing-guide Enjoy, Tui Team

Hi, So when I transplanted my passion fruit plants I added a cup or so of worm compost and potting soil was used to plant them in mixed with soil. So the flowers are turning brown and dropping. I think it's too much nitrogen. How do I have help them! I made a mistake by adding extra compost I know :( but will they burn! I don't want them to die on me. What can I do to remove some of the nitrogen from the soil? I heard wood chips but which kind?
Ana
Our passionfruit took off this season covering the side of the garage giving lots of fruit..should we now cut it back?
Laurel Amon
Hi Laurel, in spring when the risk of frost has passed remove weak or dead growth, reduce vigorous shoots by about one third and thin out overcrowded growth and vines that are growing where you don?t want them. Pruning will ensure the vine is vigorous and produces fruit. When temperatures warm up start feeding it a fertiliser rich in potassium (potash) so that you get good flowering and fruiting such as Tui NovaTec Premium fertiliser. All the best, Tui Team
jenna
Hi Ana, it sounds like you have done all the right things for your passionfruit plants. If they are not too big, suggest digging them up and growing them in tubs for a season. It seems you may have added too much good stuff to your soil at the start. Let the soil settle down and replant in 6 to 12 months. All the best, Tui Team

Hi our golden queen peach tree produced plenty of fruit last year but then the fruit rotted on the tree when it ripened. It is covered in beautiful blossom now, how can I prevent this happening this year? Thankyou.
Barb
Hi Barb, it sounds like your peach tree suffered from brown rot which is a fungal problem. You may be a little late to spray now, ideally copper oxychloride should be applied at green tip and again 10 days later. If your green leaves haven?t appeared you can still spray now. All the best, Tui Team.
jenna
Good to know thanks. Also info on passion fruit feeding - will do more seaweed fertiliser thanks
Jo Cottingham
Hi, my Golden Queen peach tree has had a bumper crop for years. Summer 2016/2017 the tree was laden then in January the fruit looked mouldy and we didn't get any. This season it has lots of beautiful green leaves but only 8 or 9 peaches. My neighbour told me that the problem last season was because I had watered the whole tree and it got mildew over night ?? I haven't sprayed the tree or done anything to it ... please advise, cheers Meg
Megan
Hi Meg, it sounds like your tree more than likely has brown rot, which is a disease that affects the fruiting capacity of the tree. This Infection would have laid dormant over the winter and then when the trees flowered in spring it becomes active again causing the blossoms to turn brown and wilt. Sadly even a few infected flowers can host enough fungal spores to ruin a whole tree and limit its capacity to fruit significantly. Treat your tree over winter with a copper-based spray program, starting in autumn then in spring. All the best ^Tui Team

I have about 12 small starter seedlings grown from seeds and the leaves and stalk have started to yellow, they have good soil and I added a very small amount of coop poop. I first covered them with a plastic wrap to create a warmer humid environment, but as its warmed up I have tried placing them outside in the sun. If it is a colder night I put them in the window inside the house. I'd hate to loose them, what do you think I could do to promote a healthy plant?
Beth Geddis
Hi Beth, at this time of year the plants naturally go into a state of dormancy, in some regions they totally lose all their leaves in others they lose only a few. Keeping them protected from the cold weather will help speed up growth and further establishment in the spring. Just check the plants have good drainage in the pots as they hate wet feet. ^ Tui Team

Wonderful information
Alma Bainbridge
Hello, My passion fruit vine broke off and the new growth has shriveled up and died. It was doing well before. What Am I doing wrong? Thanks.
Danny Aguilar Jr
Hi Danny, it sounds like your passionfruit has a root disorder, photo's are always helpful in determining what is wrong with a plant. If it is a root rot then the plant will need to be removed and start again with fresh soil to replace the soil that may be infected with soil-borne fungi. Before doing that, try applying Tui Organic Seaweed Plant Tonic to the plant every 7 days at a rate of 100ml per 9L watering can until the plant shows signs of recovery. Other things that can cause plants to wilt like that is over feeding with fertiliser, do not apply fertiliser until the plant recovers, only apply Seaweed Plant Tonic for now and hopefully that will be successful. The Tui Team.
Hi Tui, one of my passionfruit vines has being growing well - laden with unripe fruit but I recently noticed the vine has started dying and yellowing in late November and fruit starting to shrivel. Any suggestions - I had this happen last year too. Thanks, Colleen

Hi Colleen, this is likely to be a fungal disease called Brown Spot or a root rot disorder called phytophthora, passionfruit are susceptible to both.
Brown Spot is prevalent in warm humid weather in spring and summer, and appears as brown ring spots on the fruit which can shrivel, the foliage starts yellowing and dying back. Remove affected fruit, pick up any fallen fruit and dispose of in the rubbish rather than the compost to prevent the disease spreading. Cut out the dying parts of the vine. Avoid overhead watering and wetting the leaves and water around the base of the vine. Lightly prune the vine to improve airflow around the plant. Maintain regular watering, especially in dry periods. Passionfruit do a lot of growing in a season and so require regular fertiliser applications, feed the vine with Tui NovaTec Premium or Tui Citrus Food. Feed once a month during the growing season (spring and summer). Regular applications of a copper based fungicide spray are effective as a preventative measure throughout winter and spring, avoid spraying when the vine is in flower.
Phytophthora is a soil borne disease that causes root rot and can become a problem if the soils are not well drained, passionfruit require a free draining soil and don't enjoy heavy water logged soils. Irregular watering can also lead to root rot disorders, the plant dries out, water is applied and the plant takes up a lot of water, causing the roots to burst, soil borne diseases enter the plant through the root system. If it is phytophthora, the plant may need to be removed if it doesn't recover. You could try applying a seaweed based plant tonic such as Tui Organic Seaweed Plant Tonic to stimulate root growth, cut back infected plant material and fruit, dispose of in the rubbish or burn, do not compost, make sure the vine is consistently watered, mulch around the vine to help conserve soil moisture and keep the vine well fertilised.
