Yes! We sell dahlia tubers seasonally, available in the lead-up to dahlia season. Keep an eye on the shop for when they're listed, or contact us to find out more.

Shake well before use and mix at a ratio of 1:100 with water. Apply the mixed solution every 3 to 4 weeks, or weekly for optimum results.

Flowers, vegetables & lawn: Mix 3 oz with 2 gallons of water to cover 200 square feet.
Large fruit trees: Mix 2 oz with 1.5 gallons of water.
Pastures & crops: Mix 1 gallon with 100 gallons of water per acre.

Store in a cool, dry place away from sunlight. Shelf life is 2 to 4 years.

Feed at half strength (1:200) every 2 to 3 weeks for 6 to 7 feeds, starting early in the season and continuing until early September. Feeding continues right through blooming — it's only in the final 4 weeks before digging up tubers that you should stop.

Once plants begin to bud, alternate weeks with a liquid potash. This helps with stem strength, bloom colour, and tuber production.

Vigor Plant Booster is best used as a soil drench, since it works as much as a soil conditioner as a fertiliser. Foliar feeding is also an option at a weaker ratio of 1:500, including for rooted cuttings and small seedlings.

As a general guide, mix 2 oz into a 2-gallon watering can — enough to feed 50 to 60 plants when applied as a soil drench.

Yes. Apply Vigor Plant Booster around two days before a heatwave hits. The seaweed component increases the plant's cell size, helping it hold more moisture and cope better with heat.

Any good quality liquid potash works well alongside Vigor Plant Booster during the budding stage.

Apply Vigor Plant Booster when the soil is slightly damp. This helps the soil soak it up more effectively. Following up with a light watering afterwards can also help carry it down to the plant's root zone.

Yes, that's fine. On hot days, if you're applying with a watering can or have micro sprays that reach the leaves, it's a good idea to wash it off the plants afterwards.

Vigor Plant Booster contains molasses (sugar), and growers who foliar feed at the 1:500 ratio have reported it also helps keep powdery mildew at bay.
