pest
Spider mite
Tiny mites feed on the leaves, causing pale spots (stippling); if neglected, fine webbing appears at the shoot tips. Worse in warm, dry conditions.
Cause
Two-spotted spider mite (Tetranychus urticae).
What to do
- direct: biological control with the predatory mite Phytoseiulus persimilis; in greenhouses, an acaricide at least 3× at intervals of 3–5 days
- preventive: raise humidity, do not let plants dry out
disorder
Scorch, sunburn and drought
Dry brown leaf edges and tips, dried-out patches; typical of newly planted plants, full sun and wind, or lack of water.
Cause
Scorch and incorrect (insufficient) watering; for outdoor plants, wind as well.
What to do
- in the first year, water regularly and generously, and mulch
- shade sensitive species or plant taller neighbours beside them
- cut off damaged leaves
This is general information. When using plant protection products, follow the label.
Planting step by step
- Set out the pots by number
Do not plant anything yet. Set the pots out on the border exactly by the numbers in the planting plan, tall ones at the back (framework), low ones at the front (edge). - Check the spacing
Step back and look from above. There should be gaps between the plants. They will fill them once they have grown together. The recommended spacing is given for each plant (spacing in cm). - Photograph the layout
Before you start planting, photograph the border from above. If something does not fit, now is the time to move it, not after planting. - Plant in groups
Start with the framework (the tallest, at the back), then the filler, and finally the edge. Plant to the depth of the pot, firm in and water at the roots. - Water and mulch
After planting, water generously (~10 l/m²) and mulch the surface between the plants 5–7 cm deep. This holds moisture and suppresses weeds. - Note the planting date
Make a note of the planting day. We will use it to prepare a care plan for the first, most sensitive season.
