Sustainability

We try to produce as sustainably as possible to keep our footprint small. Therefore, our letterbox boxes are made of grass paper and tomato leaf pulp is the basic component of the seed bags. The printing is either made of paper that is 30-70% recycled paper or paper that comes from agricultural waste. In addition, you have the option to plant a tree when you place an order through Regreener.

Gifting

Helianthus 'Ruby' has smaller dark red flowers, truly an unusual color. This species is branching, which means there are several flowers on a stem. Because of this, you can also cut them for a vase, the plant will just keep flowering.

Indoor pre-seeding 
Pre-sow from March to April in P9 pots. Cover the seeds with a thin layer of soil, they need light to germinate. Put them in a room at about 18 degrees in a bright place but away from direct sunlight or in a (cold) greenhouse. After germination, put cooler. Keep the soil moist. Repotting is not necessary if you sow directly into P9 pots. Harden off outside and transplant after the last night frost with 45 cm spacing. 

Sow directly
Sow directly into the soil from April to May when the chance of night frost has passed. Sow 2 seeds together every 45 cm. Cover the seeds with a thin layer of soil. Do not do this during heavy rain or on hot days to prevent the seeds from washing away or drying out. Keep the soil moist. Remove one of the two seedlings so you keep the strongest one. Provide support if necessary.

Which is what?

The terms may be new to you, here's what they all mean:

Annual- plants that bloom one summer and then die
Biennial- plants that you sow one year, and bloom the next year (and then die)
Perennial- plants that bloom several summers
Perennial- plants that survive frost and last for years

How many hours of sunshine?

Annuals plants almost without exception grow only in full sun. That means that you preferably need more than 8 hours of summer sun in the place where you want to grow them, for example from 10 - 18 hours. 6 - 7 hours will also go a long way, but the plants will grow just a little slower.

What soil?

Unless otherwise specified, annuals want nutrient-rich soil with extra compost in the spring. Read more about it in the Seed Guide.

Storing seeds

On the package of your seeds you will find the shelf life. You can use them until the date you see on it. An opened package is best stored in an airtight box in a cool and dark place, such as a closet in the hallway. Not sure if the germination is still good? Then it's best to buy a new pack. We deliberately choose small amounts of seeds in the packs so you don't have to waste seeds. Do you have any questions about this? Call 033 - 202 43 38 or email to [email protected], and we will help you further.
