Great gadget for green fingers .. the 4-in-1 plantmonitor!

The 4-in-1 plant monitor – this device leaves you in no doubt about optimal fertility, correct root humidity, light intensity and temperature! Simply insert the monitor into the pot with the plant to be monitored. With a smartphone a Bluetooth connection is made to the gadget. Through the app (“Flower Care”) you have access to the optimal growth factors per plant (a large database of plant names plus optimal growth factors is available for this) and a connection is made to the device. I have tested it, it works really well! You can get reports per period. There is a telephone helpline for people who cannot manage the installation well.

Protecting your plants from winter frosts

protecting your plants from winter frosts

Wrapping your plants well and using plenty of straw is important in severe to very severe frosts!

Winter can arrive suddenly and unexpectedly. Make sure you’re prepared .. protect your garden bananas with leaves and stram from autumn onwards! I try to get the little shoots safely through the winter with straw insulation, so that there is a chance of flowering next year. If moderate frost I use bubble-wrap and as soon as the leaves are brown, I add a layer of tarpaulin.
In severe frosts also protect palms by firstly binding the leaves together in a kind of pointed hat, and then insulating with reed mats or a few layers of fleece cloth.

And then keep your fingers crossed …

Pallet deliveries abroad

This autumn we sent a packaged Camellia to a client in Budapest. It took 12 days for the parcel to be delivered by the Dutch ‘Postnl’ company. So from now to reduce the risk of accidents to our precious plants we are advising foreign clients to accept deliveries by pallet only!


Beautiful Camellia sinensis

tea Camellia at Nursery De Groene Prins

Camellia sinensis

The earliest Camellia to bloom is Camellia sinensis which is cultivated worldwide for the production of tea.

Foodies beware: Camillia sinensis has numerous subvarieties. Those cultivated in the mountains of Korea and Japan are hardy! And it’s nice that these plants are the first to introduce the Camellia flowering-season with white blossom and yellow stamens. Usually a frost-sensitive tea plant with larger leaves is available: Camellia sinensis var. Assamica, which doesn’t survive our cold winters planted out!
