Rocket Astra. A British bred Rocket which replaces our popular variety ‘Skyrocket’. Rocket ‘Astra’ is vigorous, with superb bolting tolerance even under poor soil or adverse weather conditions. The finely cut leaves have a traditional peppery flavour and make an attractive addition to salad bowls or wilted as a replacement for spinach. This easy to grow salad crop can be harvested in just 21 days from sowing. It’s improved vigour makes Rocket ‘Astra’ ideal for growing all year round, in an unheated greenhouse or under cloches during the winter months.
Height and spread: 15cm (6″) if harvested regularly or up to 60cm (24″) if left uncropped.
March – September
January – December
How to sow
Direct sow rocket seeds from April to September outdoors or October to March under glass, into well prepared, moist, well drained soil in sun or semi shade. Sow seeds thinly at a depth of 1cm (1/2″) in drills 45cm (18″) apart in soil which has been raked to a fine tilth. When large enough to handle, thin rocket seedlings to 23cm (9″) apart, or leave un-thinned and harvest as ‘baby salad’ leaves or as a ‘cut and come again’ crop. Sowings made in late summer will continue cropping into winter if protected by cloches, or if sown in frames, under glass, or in pots on the windowsill.
