I haven’t been too hot on pest control this year so far and unfortunately it shows on my broad bean patch. My broad beans have become victim to both black soot and chocolate spot.

Black soot

This year my broad beans have become victim to a massive black fly assault and as a result a black, powdery soot-like mold is covering the leaves, steam and is present on the some of the pods.

Black soot occurs after the black fly (or white fly) suck out all of the glucose and sugar from the plant, with the mold growing off of the excess sugar and glucose.

The black mold can be particularly damaging to your plants the mold can block out any light reaching the plant which will lead to a growth deficiency.

Sooty mold will also attract other pests including ants, aphids and more black and white fly.  I need to first address the pest problem before I look to eradicate the mold problem.

Chocolate Spot

To add to my black mold woes, I’ve also got a dose of chocolate spot on my broad beans. Chocolate spot is a fungus and is spread via the air and the rain.

In recent weeks we’ve experienced very wet and humid conditions which has caused a secondary bout of chocolate spot.

Chocolate sport performs well at a temperature between 15° and 22° – and guess what, that’s been the average temperature of the UK over the past few days!

Chocolate spot is a little brown spot that appears on the leaf of the plant but can also affect the stem of the plant, which will eventually lead to the plant collapsing in a horrible brown heap.

Because the leaves will begin to shrivel and I’ve pretty much got the most out of my plants (crop included) I can’t say that I’m too fussed about seeing them go.

It’ll free up some space and I can look to use the area for crops that I want to grow in the autumn or winter.

In the last few weeks my broad beans have gone from strength to strength. Not so long ago I separated them into their own pots and no less than a month later I’ve decided to the plant them out.  They’ve reached about 30cm in height and they’re drying out relatively quickly, which is a sure sign that they are due to be planted outside.

My old grandad used to say, “Don’t cast a clout until May is out!” which mean not to plant anything outside because you still have a risk of frost – well, I’ve decided to take a chance, with planting these beans outside.

I have 16 plants in total and I plant to plant them in a bed with french beans (that I’m yet to sow), and some herbs.

Broad beans tend to like a little bit of support, so I’ve planted each of them with a bamboo cane, creating a bit of a rudimentary cage by the end. Broad beans are prone to a number of pests and diseases including black fly, aphids and weevils.  They’re also prone to attack from pigeons if there’s nothing else available too!

Much like the strawberries I planted outside earlier this month, I’ve dug a hole big enough to cater for the majority of the rootstock and then covered well. I’ve then wrapped the whole plant structure in string to try and deter the birds from eating the leaves of the plants.

I’ll keep you updated in about a weeks time on how things are going with the broad beans – my biggest fear is that they get decimated by the frost or they’ve been eaten by the birds. When the temperature rises I’ll look to empty the compost bin and lay down a mulch on the bed so that the ground will hold more water than usual.

After a number of mice attacks, and after the third attempt at sowing some seeds my broad beans have grown into lovely plants – which, I’m glad to say need to be separated into their own pots.

I planted two seeds to each pot and much like the brussels sprouts, the time has come to give each plant a bit more room.

Because these plants are bigger, they’re easier to handle. There’s no need to fill the new pots to the brim, just a handful of compost will do, just so that the base of the pot is covered.

Pat the plants out of their pots and pull away the two plants from the root, making sure you keep hold of as much of the roots as possible.

Place the plants into the middle of the new pot and fill the gaps with fresh compost.

Water well and hope for the best! These plants will be a target for slugs and snails, so I’ve set a slug bin to help deter any pests from eating my broad beans.
