Product Description
JBA Blight Guard
A brand new product developed for the prevention of foliar blight in tomatoes and potatoes.
This a 100% natural product with no chemicals and is safe to use in your garden.
DIRECTIONS FOR USE:
Simply add 40ml of the JBA Blight Guard concentrate to 20 litres of water and either spray onto the foliage or apply with a watering can. The measuring chamber holds approx 40ml of concentrate.
Spraying is considered to be the best method of application as you need to spray the foliage on both sides of the leaf.
The solution can also be made up in smaller batches of 10ml to 5 litres of water.
You should use this product every 7 days directly to the foliage during June - September to help combat the threat of blight.
If you have a period of weather that's more likely to cause blight (Smith Period) then use the product at the time that period is forecast.
Use any mixed solution within 48hrs of being mixed with water.
Allow 24 hours after every application before you consume any of the sprayed crops
Try not to spay directly onto the tomatoes to avoid scorch marks
This product will only help to reduce the chances of your crops getting blight and like any other product we can't guarantee that it will prevent blight in all cases.
SMITH PERIOD:
The conditions under which blight infections can be expected are known as a "Smith Period". This is a 48 hour period in which the minimum temperature is 10°C or more and the relative humidity exceeds 90% for at least 11 hours during the first 24 hours and for at least 11 hours again during the final 24 hours. As the conditions are specific these can be forecast in advance and there are plenty of blightcast reports available online.

FAQs
Please read our FAQs page to find out more.
What's the best compost for my flower bulbs?
We would recommend a compost that contains nutrients that last up to 6 months to promote strong, healthy roots, and often includes a wetting agent to improve water retention and drainage for a vibrant spring display.
Here's the perfect one: Click Here
How can I prevent my bulbs from rotting and ensure they bloom again?
Bulbs rot in wet soil! You must have light, well-drained soil. Work compost or organic matter 8-12 inches deep into the planting bed to ensure rapid drainage and aeration.
Plant most bulbs in full sun or part sun for the long-term energy recharge.
What is the most critical step for getting flowers next year after the current blooms fade?
Do not cut the foliage (leaves) after the flower dies. The green leaves need approximately 8 weeks to yellow and brown naturally. This post-bloom period is when the bulb recharges its energy (carbohydrates) for next year’s flower. Cutting them early causes bloom failure!
How deep should I plant my bulbs?
Plant bulbs roughly three times as deep as the bulb’s height (e.g., a 2-inch tall bulb should be planted 6 inches deep). This depth provides crucial thermal protection.
You'll find the exact specifications on the bulbs page/
Do you ship to Northern Ireland or the EU?
At present, we’re unable to ship to Northern Ireland due to post-Brexit regulations. The additional paperwork and costs involved would make it too expensive for customers.
We hope this situation will change in the near future.
